Mercedes-Benz outlines synergies between F1 motorsport and production car engineering
July 10, 2014
Mercedes-Benz has outlined areas of actual synergies between its F1 motorsport activities with Mercedes AMG Petronas and Mercedes-Benz Cars. While there is definitely a technology transfer between race and road car engineering, said Paddy Lowe, Executive Director (Technical) at Mercedes AMG Petronas, “it’s a more subtle process than bolting bits from one car onto another.”
There are examples of direct transfer—such as the Nanoslide technology used to coat cylinder bore surfaces (earlier post)—and then there are examples of indirect transfer, such as F1 serving as a research laboratory for developing new solutions and showing the world what is possible, he noted.

The Audi R18 e-tron quattro diesel hybrids (earlier post) that will race at Le Mans this coming weekend (14-15 June) are the lightest and most fuel efficient LMP1 racers has yet to bring to the track. New WEC regulations require up to 30% less fuel use this year.
For the powertrain, Audi, in the 25th year of the TDI engine, has developed a new diesel 4.0-liter V6 unit for Le Mans. It has been purposefully designed for efficiency and, together with many other optimizations of the race car, such as aerodynamics, helps save energy. Compared with the 2006 5.5-liter V12 Audi R10 TDI, the first TDI engine used at Le Mans, the current race car consumes about 40% less fuel while achieving comparable lap times.

The Porsche 919 Hybrid LMP1 Le Mans prototype made its premiere at the Geneva Motor Show. The hybrid prototype will be joined by the Porsche 911 RSR at the Porsche exhibition in Geneva as well as at all eight races of the World Endurance Championship (WEC), the season highlight of which will be the 24 hours of Le Mans.
Porsche 919 Hybrid development began in the middle of 2011 on a blank sheet of paper. With a 16-year absence from the LMP1 class, Porsche engineers have had to develop the racecar without the same experience of their competitors. However, the experience acquired in racing the 911 GT3 R Hybrid (earlier post) and production of the 918 Spyder plug-in hybrid (earlier post) has directly translated to the 919 Hybrid.

Renault’s Energy F1-2014 hybrid Power Unit (earlier post), designed and developed for the FIA Formula One World Championship this year, is ready for the track; the 2014 season kicks off in Australia on 16 March. New FIA regulations are driving energy efficiency levels higher this year, with two types of energy propelling the cars. The internal combustion engine will produce power through consumption of traditional carbon-based fuel, while electrical energy will be harvested from both exhaust and braking by two discrete motor generator units. Teams and drivers will balance the use of the two types of energy throughout the race.
This year, the power unit is divided into six separate elements: Engine (ICE); Motor generator unit-kinetic (MGU-K); Motor generator unit-heat (MGU-H); Energy store (ES); Turbocharger (TC); and Control electronics (CE). The combination of the 1.6-liter turbocharged direct injection V6 engine (maximum speed of 15,000 rpm) with the two motor generator units and battery energy store delivers combined maximum power output of 760 bhp (567 kW), on a par with the previous V8 generation.

Audi has released initial details on its new 2014-generation Audi R18 e-tron quattro LMP1 Le Mans prototype racer. Although the new diesel hybrid sports car appears like a continuous further development of the World Championship winning car and Le Mans winner of the past two years, due to the new LMP1 regulations that will come into effect in 2014, Audi Sport redeveloped every component.
In the new Technical Regulations, a large number of principal definitions, which concern the powertrain, body dimensions, safety and aerodynamics, were re-determined. With the new R18, Audi Sport has opted for a similar concept as in the past—albeit with new detailed solutions and an additional hybrid system. Powertrain elements include:
