Porsche Hybrid Defeats Audi Hybrid at 83rd Le Mans

Porsche won the Le Mans 24-hour endurance sports-car race for the first time since 1998 with the first non-diesel win since 2005.

Porsche’s 2.0-litre V4 turbo Petrol A123 battery powered 919 Hybrid car took first and second places, while Audi’s R18 4.0-liter V6 Turbo Diesel flywheel powered e-tron hybrid came in third. Both carmakers are owned by German-based Volkswagen AG, the world’s second-biggest auto manufacturer.

The return of Porsche to Le Mans in 2014 after a 16-year hiatus and its subsequent victory Sunday underscore how Volkswagen is stoking in-house competition on and off the racetrack, even amid additional costs. Porsche and Audi each entered three vehicles in the fastest vehicle category, Le Mans Prototype 1, or LMP1.

“This is a very special day for us,” Matthias Mueller, Porsche’s chief executive officer, told reporters in Le Mans. “It was a great team effort.”

VW is pouring money into new vehicles, technology and factories as the company plans to surpass global industry leader Toyota Motor Corp. by 2018. Maintaining a technological edge is vital for VW’s upscale brands, which also include Bentley and Lamborghini, as they vie for affluent customers with the likes of BMW AG and Daimler AG’s Mercedes-Benz.

Research Budget

Audi and Porsche accounted for 66 percent of Volkswagen’s operating profit in the first quarter. Volkswagen, which has one of the largest research and development budgets of any publicly traded company, is investing 85.6 billion euros ($96.1 billion) through 2019 to add models and production capacity.

Rising costs to develop electric cars and new digital features such as piloted driving are weighing on Volkswagen’s efforts to improve profitability, including a program announced a year ago to increase earnings at its namesake passenger-car brand by 5 billion euros by 2017. The manufacturer has taken steps to rein in costs companywide by sharing more parts among a wider range of vehicles.

Porsche and Audi have denied reports in recent weeks that they plan to enter Formula One car racing, citing high costs and shrinking visitor numbers. Formula One “needs to solve its problems alone,” Rupert Stadler, Audi’s CEO, said last month.

Audi and Porsche say Le Mans provides a better opportunity to test new technology that can be used later in road cars, such as lightweight construction and high-performance hybrid electric systems.

Ford Motor Co., the second-biggest U.S. carmaker, said Friday it will return to Le Mans in 2016. Competing in the GT racing class, the Dearborn, Michigan-based company will commemorate the 50th anniversary of its 1966 sweep of the top three places at the race.

What You Need to Know About LMP1 Hybrids Leading up to Le Mans [VIDEO]

The hybridised World Endurance Championship has introduced a new version of cut and thrust racing that is very entertaining to watch but I'm not sure either Jalopnik nor the (with respect) race commentators fully understand how the very different hybrid systems interact on the track.

The video sequence features a race for position between the Audi R18 E-Tron Quattro and the Porsche 919 Hybrid. While these cars are both in the same LMP1 hybrid class, the rules allow for a large amount of technical freedom (especially when compared to many other 'control formula' International championships).

The 2015 Audi R18 features a 558 HP (410 kW) 4.0-liter Turbo Diesel V6 combustion engine driving the rear wheels with a 272 HP (200 kW) electric motor driving the front wheels. The R18 is in the 4 Megajule class with a flywheel energy storage system can store 700 kilojoules.

The Porsche 919 Hybrid features a 500 Hp (370 kW) 2.0-liter Turbo Petrol V4 combustion engine driving the rear wheels with a 400 HP (300 kW) electric motor driving the front wheels. The 919 is in the 8 Megajule class with an A123 Lithium-ion battery energy storage system and also has thermodynamic energy recuperation using the energy from exhaust gases from the turbo charger.

The energy class regulations refer to the amount of regenerated energy that can be used each lap, for example 8 megajoules equals 2.2 kWh that can be deployed around the race track (3.6 megajoules is equivalent to 1 kilowatt hour (kWh).

Like in Formula One, the energy recuperation is pre-programmed and not directly controlled by the drivers, what might be confusing is that unlike in F1 where output from the KERS systems is driver controlled via a steering wheel mounted 'boost' button, in the WEC the KERS output is also pre-programmed. In fact KERS 'boost' buttons are banned in the WEC.

The FIA specify hybrid ‘braking zones’ where teams can program energy recovery. The hybrid output can be used anywhere around the track and is calculated by race engineers pre-race to maximise the use of this energy for fastest laps times with minimal fuel burn. As a result, what we're seeing in the video above where the Porsche 919 is said to be "running out of hybrid power" is in fact the same pre-programmed energy duty cycle used by the 919 on every laps of the race. This becomes very clear watching extended in-car race footage (the FIA WEC on-line package offers full race in-car access to all works LMP1 cars). What we see as the Porsche massively out accelerates the Audi at the top of Eau Rouge is a combination of the 919 having a 60 kW advantage over the Audi and where the Porsche is pre-programmed to apply it's 4Mj of additional hybrid power. Again, the 919 drives this duty cycle every lap.

There are other very interesting differences at play such as braking performance. Where the Audi (flywheel) and Toyota (super capacitor) systems can recover a 'full charge' during high speed braking, while the Porsche (li-ion battery) has a noticeable extended high speed braking profile, e.g the 919 starts braking a longer distance before the corner, and is belived to take several braking zones to recover a 'full charge'. This is due to the asymmetric charge and discharge curves of lithium ion batteries and is partially compensated for by the thermodynamic turbo generator which makes the Porsche 919 Hybrid the only car in the field that recuperates energy not only when it brakes but also when it accelerates.

Motorsport is a technical sport and this is exactly what racing is meant to be about, advancing automotive technology.

Audi Launch 2015 R18 E-Tron Quattro WEC

Audi Motorsport has taken the wraps off the 2015 R18 e-tron quattro scheduled to compete in the FIA World Endurance Championship (WEC).

The new version has some big shoes to fill taking into account last year's model triumphed at Le Mans, but Audi is confident they can repeat the 2014 success thanks to a more aerodynamic body. It features larger air inlets in the redesigned front wheel arches along with reshaped headlights benefiting from matrix LED and Audi Laserlight technologies. Also new are the front wing, hood and engine cover while the monocoque has been carried over.

Audi has prepared two body configurations suitable for various tracks of the 2015 WEC calendar and they have also optimized the chassis in collaboration with Michelin. The engineers were responsible for doubling the amount of energy from 2 to 4 megajoules per race lap at Le Mans and during braking the energy recovered is then sent back to the front axle during acceleration.

The electric motor has been upgraded to 272 HP (200 kW), representing a "significant increase" compared to last year's variant while the encapsulated flywheel energy storage system can now store 700 kilojoules which is 17% more than before.

The LMP1 prototype tips the scales at just 870 kg (1,918 lbs) and now consumes 2.5% percent less diesel per lap than last year in order to meet the more stringent regulations implemented by FIA. Output of the TDI 4.0-liter V6 engine stands at 558 HP (410 kW) and only five engines will be available during the 2015 WEC season.

Audi launch 2nd Generation Audi R8 e-tron @ Geneva

The second generation of the Audi R8 forms the basis for two models. Audi has made major engineering developments in its high-performance electric sports car, the R8 e-tron. The latest evolution of the vehicle takes up the multimaterial Audi Space Frame from the new series-production model.

The supporting structure was enhanced by a CFRP rear-section module comprising the luggage compartment. The walls of the CFRP luggage compartment well are corrugated. This way, in the event of a rear-end collision, more energy can be absorbed despite the reduced material weight.

Thanks to targeted modifications to the outer shell and on the wheels, the Audi R8 e tron achieves an aerodynamic drag coefficient (cd) value of 0.28. In terms of performance and range, the car enters entirely new dimensions.

The large T-shaped battery is structurally integrated into the center tunnel and behind the occupant cell – optimally positioned in the car. It supports the dynamics of the R8 e-tron with its low center of gravity. Audi produces the high-voltage battery itself, for the first time based on a newly developed lithium-ion technology which was specially conceived for a purely electric vehicle drive. In comparison to the first technology platform, the battery capacity has grown from 49 kWh to approximately 92 kWh. This progress was possible without changing the package.

The R8 e-tron achieves an electric range of 450 kilometers (279.6 mi) instead of a previous 215 kilometers (133.6 mi) with an energy density that has been increased from 84 Wh/kg to 154 Wh/kg and some other modifications to the car. The electrically powered high-performance sports car has the Combined Charging System (CCS) on board, which allows charging with direct and alternating current. Using this system, it is possible to fully charge the battery in significantly less than two hours.

The power is now twice 170 kW and the maximum torque twice 460 Nm (339.3 lb-ft). The R8 e-tron accelerates from 0 to 100 km/h (62.1 mph) in 3.9 seconds on its way to an electronically restricted top speed of 210 km/h (130.5 mph) or 250 km/h (155.3 mph). Intelligent energy management and an electromechanical brake system enable high energy recuperation rates. Targeted torque vectoring – needs-based distribution of power transmission between the rear wheels – ensures maximum stability and dynamism.

Audi uses the electrical high-performance sports car primarily as a mobile high-tech laboratory. Accordingly, the findings from the R8 e-tron help in creating a vehicle with a sedan character. Upon customer request, the R8 e-tron will be available for order in 2015 as an electrically powered sports car in supreme hand-built quality.

2015 Audi R8 e-tron confirmed with 450 km range

The 2015 Audi R8 e-tron electric supercar will have 340 kW of power and a remarkable 920 Nm of torque, sprint from 0-100 km/h in 3.9 seconds and offer a range in excess of 450 km.

The second-generation of Audi’s halo product will have more than doubles the range over the original small-batch model thanks to an increase in battery capacity from 49 kWh to approximately 92 kWh. Energy density has increased from 84 Wh/kg to 154 Wh/kg apparently without affecting packaging.

The battery powered R8 has a Combined Charging System (CCS) on board, which allows charging with direct and alternating current. Using this system, it is possible to fully charge the battery in significantly less than two hours.

The rear wheels are powered by two electric motors with specs uprated from 381 HP (280 kW) and 820 Nm (605 lb-ft) to 462 HP (340 kW) and 920 Nm (679 lb-ft). It's enough electric power to provide the Audi R8 e-tron 2.0 with a 0-62 mph (0-100 km/h) time of 3.9 seconds before hitting an electronically-capped top speed of 155 mph (250 km/h).

Audi says the new R8 e-tron serves "primarily as a mobile high-tech laboratory" that will eventually feed into technology used in a high-volume sedan — but in the meantime, if you've got the time and the money, the Germans are willing to build you one by hand. Hopefully we'll see the car on display in Geneva next week.

Audi aims to launch two electric vehicles by 2018

Volkswagen's premium Audi division aims to bring two purely electric vehicles to market by 2018 as it tries to catch up with rivals such as Tesla Motors and BMW.

Audi's Chief Executive Rupert Stadler told German daily Frankfurter Allgemeine Zeitung (FAZ) in an interview to be published on Saturday that the launch of an electric sports car and a sports activity vehicle (SAV) were under way.

The SAV would be a four-wheel drive with a range of more than 500 km (310 miles) per battery load, Stadler said.

He also told FAZ that Audi's push to develop electronic drive and digital technologies would mean the division adding 2 billion euros ($2.4 billion) to its investments by 2019. Audi's investment budget through 2018 amounts to 22 billion.

First Audi A3 Sportback e-tron plug-in hybrid drive off the assembly line in Ingolstadt

Production of the Audi A3 Sportback e-tron: Assembly – On the engine and component assembly line, the electric motor and transmission are fitted to the engine.

Approximately 50 cars every day, with the same timing and on the same assembly line as the other models: Audi is now ramping up production of the Audi A3 Sportback e-tron*. The premium manufacturer is producing its first plug-in hybrid model at the brand's main plant in Ingolstadt.

"We started series production of the Audi A3 Sportback e‑tron in the summer," said Dr. Hubert Waltl, Board of Management Member for Production at AUDI AG. "Most of the assembly work is integrated into the A3 line; no separate manufacturing is necessary. That demonstrates the flexibility and efficiency of our production planners and employees."

With the Audi A3 Sportback e‑tron, Audi is launching the mobility of the future. The compact five‑door combines a 1.4 TFSI combustion engine with a 75 kW electric motor, resulting in a total system output of 150 kW (204 horsepower). Despite the sporty driving performance, fuel consumption in the NEDC is just 1.5 liters per 100 kilometers (35 grams of CO2 per kilometer). The A3 Sportback e‑tron can travel up to 50 kilometers in purely electric mode and up to 890 kilometers more with the gasoline engine.

"We first of all ramped up production of the A3 Sportback e‑tron to about 30 cars a day in September," explained Board of Management member for Production Waltl. "Our peak is approximately 50 units each day now. In any case, we are keeping additional capacity available."

Peter Kössler, head of the Ingolstadt plant, stated: "Working with high‑voltage systems in series production was a new challenge for us, but we mastered it well. At all stages of assembly, we achieve maximum levels of safety for our employees and quality for our customers."

Safety is given top priority during the entire assembly process. All the employees who come into contact with the A3 Sportback e‑tron have received technical safety instructions for the new technology; some employee who are directly involved are qualified as specialist electricians for automotive technology.

Porsche Readying Tesla Model S Fighter

The German automaker is currently in the early stages of development for an EV that will target the Tesla Model S and will be a new dedicated fifth model range slotting beneath the existing Panamera. While details on Porsche’s first all-electric production vehicle are mostly being kept under wraps at the moment, it will likely be built on the automaker’s second-generation MSB platform that underpins the current Panamera.

It will have a shorter wheelbase than the existing Panamera sedan but will be a five-door hatchback, similar in style to the Panamera Sport Turismo concept that debuted at the 2012 Paris Motor Show. The company is hoping to keep it around 2,100 kg and its electric powertrain will provide similar performance as the Model S, though Tesla did just announced the more powerful all-wheel drive Model S P85D.

Porsche is aiming for a range of over 450 km and the company is expected to work with Audi, so we expect they will also use solid-state batteries.

Audi Confirm Tesla Model S Rival with 450 km Range for 2017

According to a report by Auto Express, Audi is also looking to join the electric vehicle sedan market with its own offering sporting a 450 km (280-mile) all-electric range.

The vehicle is currently under development according to Audi’s Dr. Ulrich Hackenberg, who also revealed that it will arrive in 2017 as an all-new model.

In the interview, Hackenberg said that he was “able to re-engineer the R8 e-tron project and technology with the team” and confirmed that it will not be a sports car.

The German automaker will use next-generation batteries in order to achieve the 450 km range, technology that is said to have up to five times more energy density than the current batteries used in vehicles such as the Volkswagen e-Golf.

VW Chairman thinks solid-state batteries can deliver 700 km range

Following persistent news leaks from 'highly placed insiders' about an all-electric version of Audi's upcoming Q8 sports SUV with 700 km battery range, VW Chairman Prof. Dr. Martin Winterkorn, has hinted at the battery technology Audi may use to achieve that range.

In a speech at Stanford University, during the award of the 3rd Science Award for Electrochemistry, Dr Winterkorn said he sees great potential in solid-state batteries.

"Increasing the specific energy of lithium-ion cells to as much as 380 Wh/l will reduce driving range drawbacks.

With a higher nickel content, much more will be feasible.

But we also need to intensify basic research into batteries with an even greater specific energy, such as solid-state batteries.

I see great potential in this new technology, possibly boosting the range to as much as 700 kilometers (1,000 Wh/l)."

In March we reported that VW were bench testing new battery chemistry capable of providing "between three and four times the power" from a given capacity. This would mean up to 80kWh from a similar volume occupied by the current Golf Blue-e-motion's 26.5kWh battery pack.

Dr Heinz-Jakob Neusser, VW board member responsible for development, speaking at the Geneva motor show, refused to name the battery chemistry, but doesn’t deny it is a lithium-air unit, which are capable of delivering huge amounts of power, but are in the very early stages of development.

Given Dr Winterkorn's statement that current energy density with lithium-ion batteries, which allow a range of 190 kilometers, is 260 Wh/l and in the same speech he references solid-state batteries @ 1,000 wh/l, a 4x increase, I think it becomes clear this is the chemistry VW are bench testing.

The Science Award Electrochemistry was initiated by BASF and Volkswagen in 2012. The aim being to foster exceptional scientific and engineering achievements in electrochemistry and to provide an incentive for the development of high-performance energy storage.
