By 2020 all BMW’s will be AWD range-extender electric cars

BMW have embarked on a radical engineering overhaul which could see all future models from the 3-series upwards, including the Rolls-Royce range, become all-wheel-drive range-extender electric cars.

The days of spot-welded steel bodies and engines that drive the rear wheels via conventional transmissions are set to be consigned to history. BMW’s plan to make all of its cars from the 3-series upwards plug-in hybrids has forced the company’s engineers to rethink the make-up of its cars from first principles.

The first move is to radically reduce the weight of future bodyshells to help offset the extra weight of battery packs. Work on BMW’s bodyshell of the future is already well advanced, and the first generation of the mixed-materials structure will be seen this coming summer, underpinning the next-generation 7-series.

It is expected to take another generation of the 3-series, expected in 2018, before BMW is ready to switch its mainstream car to this kind of carbonfibre-intensive construction. That’s partly because it will take some years to reduce the cost of this kind of construction.

The next phase in BMW's reengineering is a rethink of the powertrain. The final concept — demonstrated in Nov 2014 with a 500 kw AWD 5-series GT xDrive plug-in hybrid — is similar in basic principle to the series hybrid system that propels the Chevrolet Volt.

Where the Chevy Volt has an ICE powered generator/motor + a traction motor in a single front-wheel-drive transverse gearbox assembly, BMW will retain it's famous rear-wheel-drive bias by splitting that combination and putting the main traction motor on the rear axle while the front axle can still be driven by the ICE powered motor/generator. This also means that on-demand four-wheel drive will be available on all future BMWs.

As seen in the BMW i8, a large battery will occupy the centre tunnel and some of the space usually occupied by the fuel tank. The front-mounted engine acts as a generator in most driving situations, creating electricity to help drive the electric motors.

The front electric motor is key to the new powertrain

In normal use, the front electric motor drives the front wheels via a still-secret new type of transmission. At speeds above 80 km/h or so, the engine ‘assists’ the electric motor by attaching itself to the new transmission via a mechanical planetary system to help drive the front wheels at motorway speeds in parallel mode much like a Chevy Volt or Mitsubishi Outlander PHEV. The combustion engine expected to be driving the front wheels only 10 per cent of the time on a typical journey.

BMW won’t reveal the details of this new combined electric motor and transmission system, but we speculate BMW, like Renault and Bugatti, may be considering a disc-shaped Axial Flux electric motor mounted within the gearbox housing.

The new transmission is unlikely to have more than three ratios and could be a mechanical planetary system. It is likely to be less expensive than today’s eight and nine-speed autos and dual-clutch transmissions.

Because the new-generation engine runs as a lean-burn generator for 90 per cent of the time and the twin electric motors provide significant torque, demands on the engine are much reduced. So it probably doesn’t need a turbocharger, the accompanying intercooler system or the Valvetronic system.

The emissions control system should also be less complex and expensive, all of which greatly reduces the cost of the unit. The engine is likely to be significantly lighter, too.

The battery pack can be larger. It will fit neatly in space freed up by the removal of the propshaft and the use of a smaller fuel tank. Braking assistance from electric motors means the mechanical brakes can be smaller, lighter and cheaper.

The multi-material bodyshell will be at least 100kg lighter than that of today’s 3-series, partly offsetting the battery’s weight.

This new hybrid powertrain offers part-time and permanent all-wheel drive and can be scaled across all models. So although the new, simplified generator motors might come in different sizes and capacities — and the battery pack will come in different sizes — this powertrain can largely be shared between everything from a 3-series to an X5 to a Rolls-Royce Phantom. This will save BMW a huge amount of money in production and research and development costs.

BMW is rumoured to already be testing a four-seater with some of the above technology. Weighing less than 1,200 kg with a drag co-efficient of 0.18, the BMW prototype consumes only 0.4 liters per 100 kilometers or 706 miles per imperial gallon (588 miles per US gallon).

BMW Wants to Put an EV Charging Station In Every Street Light

BMW's MINI Plant in Oxford UK is showcasing a high-efficiency street lighting system that doubles as a charging station for electric vehicles (EVs) during the city’s second Low Carbon Oxford Week.

Known as Light & Charge and demonstrated for the first time in the UK, this innovative system is the outcome of a pilot project developed by the BMW Group and is a state-of-the-art LED street light that combines energy-efficient lighting with affordable EV charging.

Allowing cities to significantly reduce energy consumption, its integrated charge point also provides a cost-effective and simple solution which can be grafted straight onto the existing local authority street lighting infrastructure, substantially increasing the number of public charging stations. EV charging stations can be set up at any location where suitable parking is available, simply by replacing conventional street lights with Light & Charge systems.

“Light & Charge is a simple and innovative solution which aims to integrate a charging station network into the urban landscape and this is essential if we want to see more electric vehicles on the road in our cities in the future. I’m delighted that the MINI plant is the first location in the UK to showcase BMW Group’s technological expertise not only in developing electric vehicles but also as part of a much wider commitment to electric mobility,” said Frank Bachmann, Managing Director, MINI Plant Oxford.

Oxfordshire County Council and Oxford City Council are currently working in partnership to increase the uptake of ultra-low emission vehicles such as electric cars as part of their bid for funding from the Office of Low Emission Vehicles, Go Ultra Low City Scheme.

Commenting on the new innovation, representatives from Oxfordshire County Council and Oxford City Council said: “We’re pleased that we have the opportunity to take a look at this innovative new technology as part of Low Carbon Oxford week. Combining energy-efficient street lighting with a re-charging station for electric vehicles is a neat solution to the problems of on-street charging stations.”

With its modular LED design, the Light & Charge street light is much more energy-efficient than conventional street lighting and provides more effective illumination. It can be installed anywhere and its modular design can to be tailored to different locations. Up to four LED modules can be used to provide night-time lighting on main roads, while one or two modules are sufficient to provide lighting on side streets and in residential areas. As is already the case with vehicle headlights, LED technology allows more targeted light distribution with highly uni­form illumination to increase road safety and is optimised for minimum glare and light pollution. Through intelligent control electronics, the street light can adjust itself to its environment and yields energy savings by enabling the reduction of light output late at night and whenever no one is around.

The EV charging cable connects to a standard connector on the Light & Charge street light and the integrated control panel allows drivers to start charging with the swipe of a card regardless of vehicle model.

BMW and SCHERM Group launch 40-ton electric truck pilot project

The BMW Group is partnering with logistics company SCHERM Group to deploy a 40-ton pure-electric truck in the city this summer and become the first automobile manufacturer in Germany to use an electric truck of this size to transport materials on public roads.

The innovative traction vehicle, which is licensed for use on public roads, will be deployed as of this summer for just-in-time material transport over short distances. The electric truck will drive between the logistics company SCHERM Group and the BMW Group Plant Munich eight times a day, covering a distance of almost two kilometres one-way. Thanks to its alternative drive train, the truck is quiet, CO2-free in traffic and generates virtually no particle pollution for the environment. This is also reflected in the vehicle’s overall assessment in comparison with a truck with diesel engine: The environmentally friendly truck will generate 11.8 tons less CO2 per year – equivalent to a BMW 320d Efficient Dynamics driving almost three times around the world.

“Just under two years ago, our BMW i brand put sustainable mobility on the road. This pure electric truck signals that we are constantly working on innovative solutions and tackling logistics challenges,” says Hermann Bohrer, director of BMW Group Plant Munich. “We are therefore delighted with the cooperation with SCHERM.”

The BMW Group and SCHERM Group are investing a six-figure amount in the pilot project, which will initially span one year. If the vehicle proves itself in everyday driving conditions, both partners will seek to expand the project.

“After a long search, we have found an electro-mobility solution for the transport sector,” explains Rainer Zoellner, “e-truck” project manager at SCHERM Group. “We are certain to gain valuable experience with the BMW Group from this pilot project.”

The BMW Group pursues a holistic approach focused on implementing sustainability throughout the value chain. In addition to future-oriented mobility solutions, issues such as corporate environmental protection, efficient use of resources and reduction of CO2 emissions are firmly rooted in company strategy. Since 2014, the BMW Group has sourced more than half its global electricity needs from renewables.

SCHERM Group is an international systems provider offering solutions for the logistics, transport, real estate and service sectors. As a provider of services for the entire value chain, the company employs a workforce of around 2,000 employees at 14 locations and on a mobile basis in around 500 company-owned trucks. Sustainability is an important factor the company has defined as a fundamental value.

BMW doubles i8 production to meet demand

Although BMW has doubled the production capacity for the plug-in hybrid i8, the order backlog is, according to Production Director Harald Krüger still at 4.5 months.

"We are really proud to see how this demands develops for a completely new car," Kruger said at the BMW Financial News Conference. Pride partly because of the spectacular E-athletes have been accepted even better than expected in the market, and secondly because the production team at the Leipzig plant has got a handle on the production processes of the vehicle with a high carbon content faster than expected.

Since launch in summer 2014 a total of 1,741 i8 were delivered. Given the high demand BMW have doubled the production number. Currently 20 cars per day will be built. Nevertheless, demand is still rising.

Overall, BMW sold 17,793 i models last year including 16,052 i3. Norbert Reithofer acknowledged that BMW are satisfied with the development because of the valuable experience developed through the i-series with Reithofer emphasizing the goal of electrification power trains through all series.

BMW Developing Future Batteries with Samsung SDI

BMW announced that it is developing future batteries with Samsung SDI. Also, it will use a Samsung SDI battery in its PHEV model of the BMW 3 series.

During its annual press conference in Munich, Germany, on March 18, BMW Automotive Group's purchasing division head Klous Draeger said, “We are in a very good relationship with Samsung. Last year, we signed an MOU for long-term cooperation with Samsung. Currently, we are developing future batteries together.”

He continued, “We are not sure if we would cooperate with other companies in the future. The only thing we are certain of is that we are in good cooperating relationship now. In five or 10 years, if we produce too many electric cars and demand exceeds supply, only then might we consider getting batteries from other companies. At the moment, we have no plan to get batteries from other firms.”

This is a very rare case that a high-ranking executive in the BMW Group mentioned particular batteries in an annual press conference. The industry believes that the BMW Group is working hard for cooperation with Samsung SDI.

Draeger said, “We will use Samsung SDI’s batteries in our plug-in hybrid electric vehicles based on its compact sedan 3 series next year.”

In July last year, Samsung SDI signed an MOU with BMW Group at BMW Driving Center on Yeongjong Island, Incheon, to supply electric car batteries worth trillions of won in the medium and long term. At that time, the two companies mentioned only the supply deal of Samsung SDI batteries for BMW's i3 and i8 models.

Samsung Group’s venture capital arm recently led a $17 million round of financing for Solid State Lithium Ion battery maker Seeo Inc. California-based Seeo currently has cells (though not in use commercially) capable of operating with an energy density of 350 Wh/Kg (watt-hour per kilogram), but it’s now targeting 400 Wh/Kg — around double that used in most electric vehicles today.

Samsung SDI is also currently supplying electric vehicle batteries to Chrysler and Mahindra of India.

Next BMW i model not due until 2020

BMW R&D chief Klaus Froehlich says the company will launch a third BMW i car but it won’t arrive until at least 2020.

“We are still in the strategic research phase where we brainstorm,” BMW Group r&d chief Klaus Froehlich told Automotive News Europe. “Teams that start with a white sheet of paper. They talk with customers, hold workshops, then present their ideas and we decide.”

Froehlich disputed media reports that claimed the third model after the i3 and i8 would be a variant of the X5 premium large SUV. He said the mission of the i subbrand is to change the perception of how a low-emissions car should look and perform, therefore there are no plans to re-package an existing BMW Group model and call it an i model.

Also, he said the i subbrand is supposed to be a starting point for cutting-edge innovation that progressively moves down into the rest of the automaker’s lineup. Current examples include carbon fiber, which is a key part of the i3 and i8 and is moving into other BMWs, and the i8’s plug-in hybrid powertrain, which is being added to high-volume models such as X5, 3 series and 4 series.

BMW will focus on steadily improving the i3 and i8 during the six-plus years until the subbrand’s portfolio grows again.

“We have a minimum 20 percent battery density improvement every three years, thus over the i3 and i8’s life cycle, we will offer more performance, more range or a combination of the two,” Frohlich said.

When asked whether current i3 and i8 owners would be able to switch to the more powerful electrical powertrains Froehlich said: “I don’t think a retrofit makes sense. When better batteries are available, we could then offer models with a longer range or with the same range but at a lower price.”

BMW Ceo Norbert Reithofer, who approved the i project skunkworks that developed the lightweight, low-cost carbon-fiber composites and electric drivetrains for the i3 and i8, will step down in May to be be replaced by Harald Krüger, current head of production. Krüger is known to have a more pragmatic view of electric vehicles than Reithofer.

Also BMW's R&D Chief, Herbert Diess, who oversaw the launch of the i3 and i8, and was thought to be a potential successor for BMW's CEO role was recently poached by Volkswagen to become chairman of VW's passenger car brand.

Japan Has More EV Chargers Than Petrol Stations

There are more electric-car charging points in Japan than there are petrol stations.

That surprising discovery comes from Nissan Motor Co., which reported that the number of power points in Japan, including fast-chargers and those in homes, has surged to 40,000, surpassing the nation’s 34,000 gas stations.

The figure shows that in the relatively brief time since electric vehicles were introduced, the infrastructure to support them has become bigger than what the oil industry built over decades in the world’s third-biggest economy -- at least by this one measure.

Why that matters is obvious. Nissan’s battery-powered Leaf can travel 84 miles (135 kilometers) on a charge, and the anxiety of being stuck away from home without power has restrained consumer demand. As the charging network expands and batteries become more powerful, that concern will wane.

“An important element of the continued market growth is the development of the charging infrastructure,” Joseph G. Peter, Nissan chief financial officer, told analysts on a conference call.

As charging stations become more common, electric-car support services are also emerging. Open Charge Map, for example, operates an online listing of public charging points worldwide. A mobile app combines the data with GPS technology to guide drivers to the nearest site.

Of course, gas stations typically have multiple pumps and can serve more vehicles in a day than an electric-car charging point.

Private Chargers

Also, one criticism of Nissan’s number is that many of those charging sites are in private garages. Considering the emerging so-called sharing economy, such as the online home-sharing service operated by Airbnb Inc., homeowners may soon be willing to make their chargers available to other drivers.

And more charging locations are being built all the time. Automakers have recognized that oil companies are unlikely to install plugs next to gasoline pumps, and are building their own networks.

Tesla Motors Inc. has its own network of charging stations, and Bayerische Motoren Werke AG and Volkswagen AG announced in January that they are joining the network operated by ChargePoint Inc., and plan to build as many as 100 fast chargers along the busiest corridors of the U.S. coasts, from Portland to San Diego in the west and from Boston to Washington, in the east.

Free Charging

Utilities are joining in. Great Plains Energy Inc., the Kansas City, Missouri-based utility holding company, announced in January plans to build a network of more than 1,000 charging stations in the region by mid-2015. Charging will even be free to everyone for the first two years.

Given that there are only about 9,000 public charging stations in the entire U.S., the initiative gives Kansas City, the nation’s 29th largest metropolitan area, a chance to become the nation’s electric car capital with as much as 10 percent of the nation’s chargers.

Kansas City may not be able to retain that position. PG&E Corp., owner of California’s biggest utility, asked regulators Feb. 9 for permission to build a network of about 25,000 chargers in public areas over a five-year period.

BMW, Volkswagen and ChargePoint Join Forces to Instal DC Fast Charging Network on East and West Coasts

At the 2015 Washington Auto Show, two of the top automakers, BMW of North America and Volkswagen of America, together with ChargePoint, the largest electric vehicle charging network, announced an initiative to create express charging corridors along heavily-traveled routes on the East and West Coasts. Designed to increase the number of fast charging locations, the initiative will help meet the large and growing demand for convenient, publicly available electric vehicle fast chargers, including direct current (DC) Fast charging locations, and support the adoption of electric vehicles in the United States. In the initial phase, the aim is to install nearly 100 DC Fast charging ports across both coasts, with plans to expand the program to increase access to fast charging across the country. These newly installed DC Fast chargers will be added to the growing ChargePoint network of more than 20,000 charging spots in North America.

With more than 280,000 electric vehicles sold in the United States, EV owners need more charging flexibility while on the go. The express charging corridors will provide electric vehicle drivers access to DC Fast chargers along the most heavily populated and highly-trafficked regions on Interstate 95 on the east coast, from Boston to Washington, D.C., and on the west coast covering and connecting the metropolitan areas of Portland, San Francisco, Los Angeles, and San Diego. The installations will occur both within and between relevant metro areas, strategically-spaced at a maximum of 50 miles apart, making it even easier to take long road trips in an EV.

"A robust network of conveniently located DC Fast charging stations will go a long way toward increasing electric vehicle adoption and making electric vehicle ownership even more enjoyable," said Robert Healey, Head of EV Infrastructure at BMW of North America. "The express charging corridors are another important step in the development of the U.S. e-mobility infrastructure that makes longer distance travel a real option for consumers, particularly along the most heavily trafficked portions of both coasts-making the BMW i3 and other electric vehicles even more appealing."

"Volkswagen believes in a holistic approach to e-mobility in order to create a seamless experience for the consumer," said Jörg Sommer, vice president, product marketing and strategy, Volkswagen of America. "The investment in the express charging corridor will provide e-Golf and other electric vehicle owners with the added support to travel their day-to-day and popular long distance routes."

Each fast charging location along the express charging corridors is expected to include up to two 50 kW DC Fast chargers, or 24 kW DC Combo Fast chargers with the SAE Combo connector, used in both BMW and Volkswagen electric vehicles as well as many other electric vehicles that incorporate a DC Fast Charging capability. When charging at a 50 kW station, both the BMW i3 and the Volkswagen e-Golf can charge up to 80 percent in 20 minutes. Both vehicles can charge up to 80 percent in 30 minutes at a 24 kW station. Locations will also include Level 2 chargers, currently the most commonly available public charging stations, which are compatible with all electric vehicles. Level 2 stations can dispense up to 25 miles of range per hour of charging, providing a full charge for the BMW i3 and the VW e-Golf within 3.5 to 4 hours.

The DC Fast charging stations will be part of the ChargePoint network and can be easily accessed with a ChargePoint or ChargeNow card or with the ChargePoint mobile app.

"Our goal at ChargePoint is to get everyone behind the wheel of an EV and provide EV charging everywhere they go," said Pasquale Romano, ChargePoint CEO. "With strategically-placed stations where drivers need them, these express charging corridors will give EV drivers the freedom to go farther and have an EV as their only car without limitation."

Installations have already begun on the west coast, with the first location in San Diego County. There is a target of nearly 100 DC Fast charging ports in the first phase, available by the end of 2015. DC Fast chargers along the express charging corridors are expected to be installed in convenient locations such restaurants, shopping centers, rest stops, and more. ChargePoint will leverage its existing customer base and knowledge on usage to pick strategic locations either where drivers currently charge, or to fill in spaces where there is currently a lack of infrastructure.

With the investment, BMW, Volkswagen and ChargePoint are providing drivers with the ability and confidence to enjoy longer distance driving and recharge their electric vehicles quickly, ultimately leading to greater electric vehicle adoption.

BMW sell almost 18,000 “i” vehicles in 2014 and ramp up production

Around 17,800 customers have taken delivery of a BMW i vehicle in 2014. Global deliveries of the BMW i3 total 16,052; nearly three-quarters of those sales occurred in the second half of the year, following the vehicle’s late-spring market launch in several major markets including the USA. The keys to a total of 1,741 BMW i8s have been handed over to customers since it went on sale in the summer.

Due to the success of the BMW i vehicles, their production continues to ramp up. Harald Krüger, Member of the Board of Management of BMW AG responsible for Production said,

“Our production lines in Leipzig are highly flexible and we have switched more production to the i8 to reduce customer waiting times to a better level. Meanwhile, more than 100 BMW i3’s leave the plant each day. The BMW Group is the first automotive company to manufacture using significant quantities of carbon fibre in series production and the success of these cars speaks for itself.”

BMW plans to offer plug-in hybrid versions of all their main models including Mini and Rolls Royce brands.

BMW to Show Wireless EV Charging @ CES

BMW is trying to make charging cables optional as it plans plug-in hybrid versions of top models from the 3-Series to the X5 sport-utility vehicle.

BMW will show wireless charging technology in the i8 hybrid sports car at this week’s Consumer Electronics Show in Las Vegas. Using a magnetic field to transmit electricity between a base pad on the garage floor or street and a coil on the underside of the vehicle, drivers would be able to avoid retrieving cables from the trunk and getting their hands dirty re-folding them.

“Inductive charging offers important convenience benefits for drivers of electric or plug-in hybrid vehicles,” the Munich-based luxury-car maker said.

BMW and Mercedes-Benz owner Daimler AG agreed last July to work together on wireless charging. Under pressure to meet tough emissions regulations, both carmakers have promised to broaden their range of electric vehicles. Mercedes-Benz already offers the electric B-Class and a plug-in hybrid version of its top-of-the-line S-Class model.

Today’s prototype takes two hours to replenish the battery of the i8, which can drive in electric-only mode for 23 miles, about the same time as using a normal cable. BMW also sells the i3 battery-powered city car as part of the “i” sub-brand it created to showcase its clean-car technology.

BMW had already worked on contactless charging in a previous partnership with Siemens AG, testing prototypes in Berlin in 2011. Fulton Innovation, a unit of Alticor Inc., also showed the technology that year on Tesla Motors Inc. (TSLA)’s Roadster electric model.

BMW say Auto Industry Switch to Electric Cars Not Far In Future

BMW gives the signal of change in the auto industry saying that the moment to move to electric cars is not that far in future.

The evolution of electricity storage technologies will ensure the appearance of more efficient batteries and the launch of electric cars with ranges comparable to that of fossil fuel cars. BMW officials think that moment will soon be upon us.

One of the core people in BMW’s organization chart, Ian Robertson, said that electric cars that run on hydrogen fuel cells may be the solution for the future of the automotive industry. But this is very unlikely to happen because the technologies that will enable more efficient energy storage in “normal” batteries will evolve and will radically transform ranges and load times of conventional electric cars.

“We’ve said we’ll continue to invest in hydrogen and that will result in a small number of production test vehicles being made to prove the technology works. The real issues lie not around what we can do, though, but whether the infrastructure can be built up to supply hydrogen in the marketplace cost-effectively.” said Robertson arguing that the current lithium-ion batteries will slowly be replaced by more efficient technology.

“Advances in lithium ion technology are set to be followed by a switch to lithium air and then solid-state batteries. These advances over the next 10 years could see charging time and range worries disappear,” Robertson thinks.

Solid-State Batteries are one of the solutions proposed by technology companies. This battery is based on solid electrolytes instead of liquid electrolyte from today’s batteries. This technique allows using conventional electrodes and they are changed with some Lithium Metal. In this configuration, a battery can store two to three times more energy and provides short charge times, thus improving the level of safety: the battery does not contain the flammable liquid presently found on any battery on the market today.

With regards to the pace of adopting electric cars, BMW official believe that it will be accelerated by the manufacturers which, at one time, will redirect investments from classical combustion engines toward the electrical ones.

“At some point in the future the technologies will switch over. When the crossover comes and the focus becomes electricity, the rate of learning will accelerate even faster. Relatively, that time is not far away” concludes Ian Robertson.

BMW i8 vs BMW M1 track battle [VIDEO]

The new BMW i8 is a futuristic stunner, with a hi-tech duo of an electric motor and petrol engine from the MINI Cooper. Jump back more than three decades and the last mid-engined car to wear a BMW badge was the M1 - which turned just as many heads when it debuted in 1978.

To find out how thirty years of evolution has changed the BMW supercar, Auto Express took along a classic M1 to meet the new i8 at the test track. The BMW i8 features a 1.5-litre three-cylinder turbocharged petrol from the MINI Cooper driving the rear wheels, while an electric motor drives the front. Under the engine cover of the M1 is something altogether much more traditional: a 3.5-litre six-cylinder unit putting out 277bhp and 330Nm of torque. This compares to 357bhp and 570Nm in the i8.

On the track, the two cars feel very different. The M1 wasn't pushed too hard due to its age and value - mint examples fetch around £400,000 - but it performed brilliantly around the track. The gearbox has lovely action, the steering is perfectly weighted and the chassis feels perfectly matched to the power on tap.

Jump into the i8 and it feels very futuristic. There's instant power on tap due to the combination of the electric motor and the engine in Sport mode, with a great soundtrack in the cabin - it's even reminiscent of the sound of the M1. There's plenty of grip, too, and the performance is great. It's rather special and doesn't feel like any other BMW.

Both the i8 and M1 are true BMWs at heart. It's not often that BMW breaks the mould and builds a mid-engined car, but when they do, they know how to make their mark.

BMW Plans to Roll Out Plug-in Versions for Its Top Cars

BMW plans to offer plug-in hybrid versions of all its main models, including the best-selling 3-Series sedan, as the world’s largest maker of luxury vehicles reacts to tighter emissions regulations.

Carmakers are adding electric motors to improve fuel efficiency and make their vehicles viable in cities like London, which has set up a low-emission zone to improve air quality. Plug-in hybrids have batteries that can be recharged from electrical outlets and can drive emission-free for longer distances than conventional hybrids.

BMW is presenting a prototype of a plug-in hybrid 3-Series today in Miramas, France, the company said in a statement. The car combines a four-cylinder gasoline engine with an electric motor and can drive about 35 kilometers (22 miles) on battery power.

The German carmaker also plans to roll out a plug-in hybrid version of its X5 sport-utility vehicle and other “core-brand” models, according to the statement. Electric versions from the Mini and Rolls-Royce brands are also “a possibility,” said Manfred Poschenrieder, a spokesman for the Munich-based company.

Bayerische Motoren Werke AG (BMW) created the ‘’i’’ sub-brand for showcasing its clean-car technology and safeguarding its image as a maker of sporty vehicles. The first cars from the BMW i unit were the i3 battery-powered city car and the i8 plug-in hybrid super car. The company didn’t specify a timeframe for rolling out plug-in hybrid versions of its models.

BMW reveal 500 kW eDrive plug-in hybrid system

Following the success of the BMW i3 electric car, and the i8 hybrid supercar, BMW has developed an even more powerful petrol-electric drivetrain that could underpin prestige and performance models in the future.

The new system is part of an increasing investment into hybrid electric powertrains, starting with the upcoming 3-Series ActiveHybrid. This one in particular will sit at the top of the range. Expect it to appear in the firm's large saloons and M-powered SUVs in the next few years.

Dubbed Power eDrive, the new system forms part of a extended range of modular hybrid drivetrains being developed in a performance-based EfficientDynamics engineering program at BMW's research and development centre in Munich and envisaged for launch on a limited number of BMW Group production models in what it describes as "up-market segments" before the end of the decade.

The new hybrid system aims to provide the sort of smooth yet urgent step-off performance qualities delivered by a contemporary battery powered electric drive systems like that offered in the Tesla Model S, albeit with an overall range described as being over 600km thanks to a range extender function, including a 100km range on electric power alone.

Revealed in a 5-series GT bodied prototype, the most powerful of BMW's new modular hybrid drivetrains uses the company's new 170 kW turbocharged 2.0-litre four-cylinder direct injection petrol engine in combination with two electric motors – a 150 kW version of the i3's synchronous unit mounted up front in the space usually taken up by the torque converter in the car's eight-speed automatic gearbox and an even more powerful 200 kW unit set within the rear axle assembly.

All up, it is claimed to boast a combined system output of 500 kW along with a torque loading that, BMW engineers suggest, reaches beyond 1000 Nm – figures that easily top the 338 kW and 720 Nm of the existing 6.75-litre V12 petrol engine used by the 11-year-old Rolls-Royce Phantom.

The principle behind BMW's Power eDrive system is a maximization of electric motor performance.

"The electric motors provide approximately two-thirds of the combined output, with the combustion engine accounting for the remaining third," says Franz Drescher-Kaden, a BMW concept engineer responsible for the new petrol-electric hybrid set-up.

Energy for the electric motors is provided by a 20 kWh lithium-ion battery mounted both longitudinally in the rear of the 5-series GT's centre tunnel and horizontally underneath the rear seat in a space ahead of the rear axle. It can be charged both via plug-in means and on the run using the combustion engine in a steady state mode. The fuel tank has been reduced in size from a standard 70-litres to 30-litres.

As well as acting as a generator to produce electricity, the Power eDrive hybrid system's petrol engine can also provide a performance boost with direct drive to the front wheels during kick down, in which all three power sources are used for propulsion.

Drive is nominally channeled to the rear wheels via the rear electric motor, whose reserves are sent through a multi-speed gearbox like the front motor in an i8. The introduction of the front electric motor, which operates via the eight-speed automatic in which it is housed, provides all-electric four-wheel drive. This is further enhanced by the combustion engine, which also delivers its power to the front wheels.

BMW has not revealed a weight figure for its new hybrid system. However, it does concede the addition of two electric motors as well as the lithium ion battery pack and ancillary electronic management system adds handsomely to the kerb weight. Despite this, the German car maker says the straight line performance of its 5-series GT Power eDrive prototype exceeds that of the 330 kW twin-turbocharged 4.4-litre V8 powered 550i GT, which tips the scales at 2070 kg.

Power eDrive is being developed as a scalable system with power outputs ranging from 190kW to over 500 kW, according to BMW, which says the plug-in hybrid technology will be "a natural choice for use in up-market vehicle segments".

Tesla in talks with BMW over car batteries & component alliance

Tesla Motors is in talks with Germany's BMW over a possible alliance in batteries and light-weight components, Tesla's Chief Executive Elon Musk told German weekly Der Spiegel.

In an interview published on Sunday, Musk described BMW's production of carbon fibre reinforced car body parts as "interesting" and "relatively cost efficient."

BMW uses carbon fibres from its joint venture with materials supplier SGL to make reinforced passenger cell parts for its i3 electric hatchback and i8 plug-in hybrid sports car.

Officials at BMW were not immediately available to comment.

"We are talking about whether we can collaborate in battery technology or charging stations," Musk was quoted as saying in the interview.

There were no further details on the specific nature of the alliance, however BMW and Tesla executives already met in June to discuss the creation of charging stations usable for different types of electric cars.

Rival Daimler, owner of the Mercedes brand, said last month it would continue to collaborate with Tesla even after selling its remaining four percent stake in the U.S. company. Tesla has also worked with Toyota on electric SUVs.

Tesla's billionaire co-founder Musk also told Der Spiegel that he expects Tesla to have a battery production plant in Germany in five to six years.

BMW likely to phase out internal combustion engines over the next 10 years [VIDEO]

During a recent interview with CNBC.com , mutual fund manager Ron Baron of Baron Capital revealed that two of his analysts recently visited BMW in Germany and the BMW financial team believes that a "revolution in the drive train is underway."

"We believe that BMW will likely phase out internal combustion engines over the next 10 years,"
Baron wrote in his most recent quarterly letter to shareholders of his funds.

Almost exactly 12 months ago, BMW product chief Herbert Diess told Autocar "all BMW models will soon need to be sold with some form of electrification." BMW’s head of production for large vehicles, Peter Wolf, told motoring.com.au. “We are planning to have a plug-in hybrid in each and every model series.”

We have also regularly reported on a steady stream on informal announcements from German automakers (Audi, BMW, Mercedes, Porsche) regarding their plans to build a 'Tesla killer', but Wall Street financial analysts concluding a major automaker may abandon the production of ICE power plants within a decade still comes as a revelation. It was only four years ago (December 2010) the first mass market electric vehicle, the Nissan Leaf, began deliveries to retail customers.

Baron, who holds a $250 Million position in Tesla Motors, believes that of all the major automakers, BMW is the only car company with a 'culture' comparable to that of Tesla. Baron believes the rest of the auto industry is resisting the move to electric vehicles. "As a result, they are developing electric expertise so slowly that the lead Tesla has built up through its fast growing staff ... may soon become insurmountable."

He argues automakers don't want electric vehicles to happen because their engine and transmission plants would become stranded assets. Unions don't want EVs to happen because they are easier to assemble which results in fewer jobs and dealers don't want EVs to happen because of direct sales and lack of vehicle servicing. Electric cars have 18 moving parts compared to 2,000 moving parts in a combustion engined car. EVs simply don't wear out or breakdown leading to lost automaker/dealer revenues.

With global auto sales heading towards 100 Million a year, Baron believes that in 15 years time Tesla could be selling 10 Million vehicles a year.
