Mitsubishi MiEV Evolution III Wins Pikes Peak Electric Division & 2nd Outright

Mitsubishi Motors Corporation (MMC) entered two MiEV Evolution III all-electric racecars, which combine the best of MMC's electric vehicle (EV) and four-wheel drive control technologies, in the Electric Modified Division of the 2014 edition of the world-famous Pikes Peak International Hill Climb (Pikes Peak, June 23 to June 29) in Colorado, United States.

Race Day was held on Sunday June 29 and after posting the fastest time of 9 minutes 08 seconds 188, Greg Tracy won the Electric Modified Division honors and 2nd overall. Meanwhile, Hiroshi Masuoka set a time of 9 minutes 12 seconds 204, finishing 2nd in the division and 3rd overall, dominating the Electric Modified Division. These Race Day results and the performance of the cars during the event speak volumes about the advanced level of MMC’s EV and four-wheel drive control technologies.

The race starts at an elevation of 2,862 meters and takes competitors through 156 corners on a 20 km course to the finish on the 4,301 meter summit of Pikes Peak. With an elevation difference of 1,439 meters, atmospheric pressure, temperature, weather and other conditions vary significantly between the start and finish. A feature of the race course is that it is split into three major sections: Bottom at the foot of the mountain, Middle and then Upper near the summit.

Lined by coniferous trees, the Bottom section starts with its rhythmical series of mid- to high-speed corners but all of a sudden the drivers hit a series of much tighter and difficult turns which demand the utmost care and concentration.

The Middle section is distinguished by some spectacular scenery with oddly-shaped rocks closely bordering the road. This is a very technical section as shortly after the start a series of tight hairpin bends demand precise handling as the car races along the steeply ascending road.

The Upper section is a very high-speed course taking competitors through many fast corners between craggy rocks and boulders. With little guard railing at the side of the road, this very difficult section brings with it the risk of plunging over the edge should the car slide off the tarmac. This is why the highest levels of vehicle stability are required over the high-speed parts of the section. At 4,301 meters, the mountain summit is higher than Mt. Fuji and the thin air means that cars powered by internal combustion engines lose power the higher up they go. Electrically powered cars, however, are unaffected by the thin air and so this could prove the key section in setting a really fast overall race time.

BMW i3 with F1 Technology [VIDEO]

BMW i3 is one of many cars that now come equipped with F1 technology. The carbon fibre reinforced plastic (CFRP) Monocoque is used to reduce weight and ensure road safety.

The extensive use of carbon fibre keeps the curb weight down to 1,195 kg which is much lower then either a Nissan Leaf (1,500 kg) or a plug-in hybrid like the Chevy Volt (1,700 kg).

When combined with the i3's 125 kW BLDC electric motor, which is more powerful than either the Leaf (80 kW) or the Volt (110 kW), the result is a 0-100 km/h time of 7 seconds.

Driving Tesla Model S P85 on German autobahn [VIDEO]

Norwegian Tesla owner Bjørn Nyland has uploaded a video demonstrating his Model S at Autobahn speeds.

A Tesla Model S P85 driven at it's maximum speed of 210 km/h (130 mph) has an estimated range of 154 kms (96 Miles)

Having recently returned from Munich I can vouch for the fact that driving at 160 km/h (100 mph) in the fast lane is considered slow, they really do drive at 200 km/h routinely on unlimited sections, yet the road toll is actually lower than in many other countries (including Australia).

Audi Plans Range of High-Performance Electric Cars

Audi has drawn up blueprints for a wider range of high-performance electric cars to help it take on German rivals and U.S. firm Tesla Motors, according to sources at the carmaker.

Tesla has managed to stay ahead of the pack with new technology, which has extended driving range and reduced costs. Its success and the excitement about BMW's new "i" electric series have caught the attention of Audi, which some analysts have said risks looking like a laggard in an industry where innovation is a major draw for customers.

Audi, a unit of Volkswagen, is about to launch its first purely electric car, a battery-powered version of its R8 supercar, which is due to hit European dealerships in 2015. It will offer a driving range of 450 km (280 miles), close to the 502 km of Tesla's top-selling Model S luxury saloon.

Meanwhile, Audi has scaled up its electric car plans, having devised blueprints for several high-performance electric saloons and sport-utility vehicles, two company sources told Reuters, asking not to be identified because the matter is confidential.

VW declined to comment. Audi did not return calls seeking comment. The manufacturer has shown various hybrid and purely electric concept cars since about 2009, but the latest blueprints stand a bigger chance of getting the nod for production after it lately overcame range limits.

"Germany's major carmakers all have their electric car plans ready in the drawer," Hanover-based NordLB analyst Frank Schwope said. "They want to be prepared when demand accelerates," he said. The sources at Audi did not specify how many models were being planned or the scale of any production plans.

They said, however, that one of the blueprints is for an electric version of a new Q8 SUV that would pit the brand against Tesla's forthcoming Model X. Audi has defined a range target of about 400 km for any future electric model it aims to develop, the sources said.

Audi's plans will be helped by steps underway to upgrade a production platform dubbed MLB that already underpins larger models across the VW group, such as the Audi A8 saloon and Porsche Cayenne SUV, and would cut costs for electric cars.

INNOVATIONS

Sales of electric cars are expected to surge to 2.7 million globally by 2018 from 180,000 last year as more models come to market, battery costs fall and the number of charging stations grows, according to business consultancy Frost & Sullivan. While mid-market battery cars such as the Renault Zoe and Nissan Leaf have missed sales targets, there has been more buoyant demand for premium offerings. Germany's three leading luxury carmakers are all advancing on the electric market.

Rival BMW has launched its "i" series of electric models, including a 34,950 euro ($47,400) city car, while Mercedes, whose parent Daimler owns a 4.3 percent stake in Tesla, started production in April of its B-Class electric compact.

Tesla has devised innovations that have cut the cost and raised the safety of battery packs. Its models also recharge more quickly than those of rivals, thanks to its connectors, software and efficient power management.

But the California-based company is now facing its own challenges related to scaling up further after its success. It said last week it would share its patents with competitors in hopes of speeding up development of electric cars across the industry.

Tesla executives have also met counterparts from BMW to discuss ways to promote electric cars which analysts say must include steps to create a common infrastructure and share the cost of building recharging stations.

Audi's electric-car moves highlight a change of tack at VW. In 2012 Audi shelved the R8 e-tron at request of its parent as efforts to expand the model's driving range had stalled at only 215 km.

Audi, which has since swapped R&D chiefs, has overcome the range limits by increasing the efficiency of the electric drivetrain and curbing on-board power consumption, development chief Ulrich Hackenberg has said.

"Electric mobility is a key focus of our development strategy," he said in March. "We are ideally prepared for the future with our strategic roadmap and a well-filled development pipeline."

Nissan & BMW keen to collaborate with Tesla on Supercharger standards

We recently reported that BMW is keen to collaborate with Tesla on creating possible global vehicle-charging standards, and now Nissan is also interested according to sources.

“It is obviously clear that everyone would benefit if there was a far more simple way for everyone to charge their cars,” said one executive, who declined to be named as the plans are not yet official.

Between them, Nissan, the world’s biggest electric-car manufacturer, BMW and Tesla account for about 80 per cent of the world’s battery electric-car sales.

Tesla has risen from an ambitious San Francisco start-up to account for about a quarter of the world’s electric-car market, and defy naysayers at some of the world’s largest carmakers that said that the vehicles were not commercially viable.

BMW, which has invested heavily in its electric i range, said that it and Tesla were “strongly committed to the success of electro-mobility”, and used their meeting to discuss ways to “further strengthen” the global electric-vehicle market.

BMW was informed of Mr Musk’s patent decision at the Wednesday meeting, but both companies stressed that the meeting’s timing was coincidental.

“Nissan welcomes any initiative to expand the volumes of electric vehicles,” the Japanese manufacturer said. “Nissan is the market leader in EVs and has worked with other manufacturers to help proliferate the technology.”

BMW + Tesla superchargers a strategic move?

On Wednesday Tesla and BMW met, but what specifically was discussed was not published.

“Both companies are strongly committed to the success of electromobility and discussed how to further strengthen the development of electromobility on an international level,” a BMW spokesman said today in a statement.

On Thursday, Tesla CEO Elon Musk said his company has been in talks with BMW and other automakers on the topic of promoting EVs and making better use of its German Supercharger charging stations.

Musk said that Tesla’s intent wasn’t to create a walled garden around it's supercharger network and that the company is more than happy to allow other makers to use its fast chargers.

There are number of preconditions, though. Firstly, other makers’ cars would need to be able to accept the 135kW output of the Supercharger. Secondly, rival manufacturers would have to contribute to some of the capital cost of the fast charging network.

The Germany market for long range EVs has some unique requirements. Not only is Tesla offering a special tune-up so that its Model S is capable of 130 MPH to compete against the local Porsches, BMW,s Mercedes and Audis on Germany’s unrestricted, high-speed autobahns. But the extra aerodynamic load resulting from sustained Autobahn speeds means that a huge network of very high powered (read Fast) EV charging stations is essential for the long range EV market to be viable in Germany.

With BMW, Audi, Porsche & Mercedes all having leaked plans for 400-600km BEVs there will definatly be future demand for a fast charger network in German. Establishing the Tesla fast charger standard in Germany now in partnership with BMW, the undisputed leader in EV investment, could be seen as a strategic move.

If Tesla doesn't build it, then someone else will!

BMW and Tesla executives meet to discuss electric cars

Executives from German carmaker BMW and U.S.-based Tesla Motors Inc met this week in a move which could lead to the creation of charging stations usable for different types of electric cars. Both carmakers are seeking ways to raise the popularity of battery-powered vehicles.

"Both companies are strongly committed to the success of electro-mobility and discussed how to further strengthen the development of electro-mobility on an international level," a BMW spokesman said in a statement on Friday.

BMW said the meeting had taken place on Wednesday but declined to comment in detail about the nature of the talks, or about which BMW executives had met with Tesla.

In a conference call on Thursday, Tesla Chief Executive Elon Musk said there had been talks with BMW about how to promote the use of electric vehicles and how to make better use of Tesla's network of charging stations.

Carmakers including General Motors, Ford, Chrysler, BMW, Daimler, Volkswagen, Audi and Porsche have committed to adopting a common SAE combo standard for fast-charging connectors.

Fast-charging stations allow electric vehicle owners to recharge batteries up to 80 percent in less than 20 minutes.

Today, the Chevrolet Spark and the BMW i3 for example can use the same battery recharging stations.

Tesla has, however, developed its own network of high-speed charging stations including along key autobahn routes in Germany in an effort to make electric cars viable for long-distance commuting.

Tesla's charger system can be fitted with an adapter that allows its cars, including the Tesla Model S, to be recharged on both the SAE chargers and its own system.

SHARING PATENTS

Tesla also said on Thursday that it would allow others to make use of its intellectual property in the hope of speeding up development of electric cars by all manufacturers.

Musk said this included all of Tesla's patents, including several hundred current ones and several thousand in the future.

German premium auto makers have been keen to collaborate with Tesla.

In January, Daimler Chief Executive Dieter Zetsche said the German maker of Mercedes-Benz cars was open to deepening its partnership with the U.S. firm.

Daimler holds a 4.3 percent stake in Tesla, which is already supplying it with electric motors and batteries for its Smart Fortwo electric vehicle (EV) and the new Mercedes-Benz B-Class EV.

Aero Comparo! Tesla Model S vs Volt, Prius, Leaf, Mercedes [VIDEO]

Car and Driver gathered five slippery cars to study their drag and lift properties at a wind tunnel to determine which brand did the best job optimizing its car’s aero performance.

The overall winner was the Tesla Model S by virtue of its larger 25.2-square-foot face and lower 0.24 drag coefficient, which yield the same 6.2-square-foot drag area as the Prius. Low drag is a tougher challenge with a larger frontal area, hence the Tesla’s overall win.

Petrol stations will die out as drivers plug EVs into Solar Panels at home

Petrol stations could vanish in the near future as drivers start charging their cars at home, a scientist has forecast.

Keith Barnham, emeritus Professor of Physics at Imperial College, said he and his colleagues were already producing solar panels, which were three times as efficient as current models.

“A typical (solar panel) system will generate enough electricity for typical mileage in a year.

“Free fuel for life from your rooftop. Even the most fervent opponents of electric cars like Jeremy Clarkson couldn’t argue with that.

“We need to spread the word that we have got the technology already, we just need to use it.”

A good example is EV News contributor Dr Phoebe Thornley who charges her Nissan Leaf with a 3kw roof top solar system. In Australia a 3kw PV system generates enough energy to power a Leaf for 15,000km annually which is precisely the average annual distance travelled by private motorists.

Mitsubishi enter two MiEV Evolution III racecars for 2014 Pikes Peak

Mitsubishi Motors Corporation (MMC) will enter two MiEV Evolution III all-electric racecars in the 2014 edition of the world-famous Pikes Peak International Hill Climb (Pikes Peak, June 23 to June 29) in Colorado, United States. MMC will use two MiEV Evolution III all-electric racecars, which combine the best of MMC's electric vehicle and four-wheel drive control technologies. MMC has competed twice before in the Electric Division in 2012 and 2013, and now with the MiEV Evolution III, hopes to take its first victory, this time in the new Electric Modified Division.

The MiEV Evolution III racecar is an improved and evolved version of last year's MiEV Evolution II. Main components including high-capacity battery, high-output electric motor and electric powered 4WD consisting of four electric motors have been retained with improvements made to give better motive and cornering performance. To reduce weight in the pipe-frame chassis the design has rationalized and some structural materials have been replaced.

Total motor output of four motors has been boosted from 400 kW to 450 kW and to ensure all the extra power is put down on the road surface the tires have been uprated in size from 260/650-18 to 330/680-18. Accordingly downforce has been increased with a new carbon cowl design and with wind-tunnel optimization of the spoiler and other detail shapes. Evolutionary development of the S-AWC integrated vehicle dynamics control system has improved traction control performance and has reduced wheel slip by controlling vehicle attitude more precisely when near the limit of adhesion. These improvements allow the driver to extract the full potential of the racecar's awesome handling with confidence and reassurance.

The race team will feature the same drivers as last year. One MiEV Evolution III will be driven by two-time Dakar Rally overall champion Hiroshi Masuoka, who piloted the MiEV Evolution II to second place honors in the Electric Division last year and also act as team captain. The second MiEV Evolution III will be piloted by Greg Tracy, six-time Pikes Peak motorcycle champion whom last year drove a MiEV Evolution II to third place in the Electric Division, his first time challenging the race on four wheels.

The team technical director and chief mechanics are mainly all engineers in MMC's Development Engineering Office. Responsible for the maintenance of the racecars during the hill climb event, they will also be gathering data and knowhow which will be fed back into the advance development of MMC EV technologies, its S-AWC (Super All-Wheel Control) integrated vehicle dynamics control system and into the company's "e-EVOLUTION" - a fusion of electric motor drive and the S-AWC system.

Tesla announce Model S pricing for Australia

Tesla Motors has has rolled out Australian pricing for its Model S which starts at $96,208 plus on-road costs for the Model S 60 and tops out at $133,257 for the high-performance P85.

The base model can be had for about $107,000 driveaway in Melbourne or Sydney, while the range-topper is about $140,000.

This reflects the growing affordability of electric cars, as this pricing is about half that of the Tesla Roadster which pioneered the brand Down Under in 2011 at $222,995 driveaway for the base model and $260,535 for the Sport.

Australian orders for the American-made plug-in Model S are now being taken on Tesla’s website, two years after the model went on sale in the United States.

Tesla, which expects to sell 35,000 of the five-door liftback Model S sedans globally this year, is planning to re-establish a retail showroom in Sydney, along with sales representation in Melbourne and a dedicated service facility.

Expected to land in Australia by August, the three-model range will offer three levels of performance, depending on battery size and electronic tweaks.

The base Model S 60 boasts 225kW of power from its 60kWh lithium-ion battery pack, driving the large sedan from zero to 100km/h in 6.2 seconds – about the same as a V6 Holden Commodore – and to a top speed of 190km/h. Official driving range on a full battery charge is said to be 390km.

Stepping up to the mid-range $111,807 Model S 85 adds more battery oomph (85kWh) for more power (270kW), faster acceleration (5.6 sec to 100km/h) and greater range (502km).

The $119,900 flagship P85 – P stands for performance – has the same 85kWh battery and 502km range as the 85 but adds an enhanced electric drivetrain for faster acceleration.

Tesla says the P85 can cover the 0-100km/h sprint in 4.4 seconds – a split second faster than the 4.4-litre V8 BMW M5. And it is about $100,000 cheaper, too, at least in base format that is well short of the M5’s feature level.

If the Tesla buyer ticks all the boxes for optional extras, including a performance suspension and 21-inch wheels package, ‘tech’ package (a bundle of electricals that includes sat-nav, keyless entry, memory seats and power tailgate, among others), and other extras, the price can top $170,00, plus on-roads.

In standard form, the Model S is available in one exterior colour – flat black – with 19-inch alloy wheels, cloth seats and piano black interior trim.

Metallic paint in a variety of colours costs between $900 and $1800, while leather is also $1800. A glass panoramic roof is a $3100.

The standard on-board charger comes with a 40-amp single-phase wall connector. For an extra $1800, a buyer can have twin chargers fitted to reduce charging time.

As well, Tesla promises to establish a network of “Tesla Superchargers” that it claims can replenish the batteries by more than half in a little as 20 minutes. The facility will be free to Model S 85 and P85 owners, but requires a $2700 tweak for 60 buyers.

Because “green” cars get luxury car tax breaks in Australia, but the flagship P85 still attracts $13,357 in tax.

The Tesla website provides driveaway pricing that varies by state and territory, with the Australian Capital Territory the cheapest and Western Australia the dearest. For example, the driveaway price for the base Model S 60 in the ACT is $103,095, while in WA it is $109,363.

Tesla Model S pricing:*

Model S 60 $96,208
Model S 85 $111,807
Model S P85 $133,257

Google launches an all-electric self driving ‘pod’ car [VIDEO]

We have seen battery powered 'pod' type driver-less cars before with the ULTRra PRT at Heathrow airport and the recently announced 100 vehicle trial on public streets around Milton Keynes. These vehicles can only navigate on purpose built guideways as opposed to merging with general traffic. Google has demonstrated a driver-less pod type electric vehicle based on their self-driving technology.

The two-seater prototype vehicle is Google’s reimagination of what the modern automobile should look and feel like if you took the human out of the transportation equation and designed something solely to chauffeur passengers from point A to B.

“The project is about changing the world for people who are not well-served by transportation today,” Google co-founder Sergey Brin said at the inaugural Code Conference in Rancho Palos Verdes, California. “There’s not great public transportation in many public places in the United States.”

The car — which was conceived and designed by Google, unlike the ones it previously modified — lacks many of the trappings of a normal car, and that includes the three essentials: A steering wheel, an accelerator and a brake pedal.

Google wants to get these cars on the streets ASAP. The company plans to start testing them in Mountain View, Calif., later this summer. They hopes to build at least 100 prototypes over the next two years, and get them into the hands of volunteer drivers — or nondrivers, as it were — as soon as the system is evaluated to be safe.

Australia Post takes delivery of first Renault electric vans

In an Australian-first, Renault's 100 percent electric-powered delivery vans will shortly join Australia Post's fleet in Melbourne and Sydney.

The Renault Kangoo Maxi Z.E. (Zero Emission) electric van, currently not sold in Australia, is widely used across Europe and the United Kingdom and will be used exclusively by Australia Post from mid-2014 for a 12 month proof-of-concept.

Australia Post Head of Environmental Sustainability, Andrew Sellick said using the Renault Kangoo Maxi Z.E. for day-to-day parcel and letter deliveries is another exciting step in Australia Post's sustainability journey and an important step in assessing the real-world use of electric commercial vehicles.

"The Kangoo Maxi Z.E. assessment is part of a broader strategy to explore alternative fuels at Australia Post, including using biofuel and hybrid vehicles in our current fleet.

"The electric vans will be powered by accredited GreenPower from renewable energy sources to ensure we are maximising the potential to reduce our environmental impact.

"The Kangoo proof-of-concept will give us a clearer picture of the benefits of using electric powered delivery vans. Through this assessment we expect to see at least a 50 percent reduction in energy costs and a 100 percent reduction in carbon emissions to comparable combustible-engine vehicles in our fleet.

"While at this stage we are working with Renault to prove this concept, if the vans perform well across the range of metrics we'll be measuring them on, the future potential is very exciting. We hope this initiative will ultimately help drive the commercialisation and acceptance of electric vehicles in this country."

Renault Australia's Managing Director, Justin Hocevar said "we are excited to broaden our existing relationship with Australia Post in rolling out the Kangoo Z.E. in Australia. Through our partnership with Australia Post, we are able to comprehensively investigate the business case for introducing the fully electric Kangoo Z.E. van in Australia in the future."

Some of the alternative fuel initiatives implemented across Australia Post's network have included the rollout of:

  • 740 electric bikes that have replaced motorbikes at various locations
  • 100 hybrid vehicles introduced to the fleet to replace existing six cylinder vehicles, reducing emissions by over 30 percent
  • 25 hybrid trucks introduced into StarTrack's fleet of vehicles, improving fuel efficiency by 20 percent improvement on average
  • implementing 5 percent of bio-diesel to StarTrack's fuel supply in 2012 - an initiative which has saved approximately 820 tonnes of carbon

    Australia Post's Port Melbourne Business Hub will receive 2 Renault Kangoo Maxi Z.E. vans mid-year, with the remaining 2 vans that are part of the 12 month assessment delivered to StarTrack House in Sydney by year-end. Charging stations at each location will be powered by accredited GreenPower sources.

    The charging station at Australia Post's Port Melbourne Business Hub is funded by the Victorian Government Department of Transport, Planning and Local Infrastructure.

    Solar House Uses EV to Realize 75% Energy Self-sufficiency

    Sekisui Chemical have launched the "Grand Two U V to Heim," a wooden smart house that links an electric vehicle (Nissan Leaf) and a solar power generation system with an output capacity of 10kW in the aim of realizing practical energy self-sufficiency.

    By appropriately controlling a solar power generation system and the rechargeable battery of an EV, the system is able to provide up to 75% of the amount of electricity consumed by the entire house throughout the year.

    Conventional "V2H" systems, which provide electricity from an EV to a house, have various limitations. For example, when electricity is supplied from an EV to a house, it is necessary to temporarily cut off electricity from the power grid. To solve this issue, the Grand Two U V to Heim comes with a grid connection system that also controls an EV and a solar power generation system.
