"Racing improves the breed". So said the late Soichiro Honda, believing that the lessons learned on the racing cars and motorcycles could be used to improve the marque's road vehicles.
The evidence is plain to see. Technologies such as anti-lock brakes, traction control, unibody chassis, electrically adjustable shocks and many others have all stemmed from motorsport and have undoubtably helped to improve performance and safety in road vehicles.
BMW Experts take on the electric challenge
BMW have taken the theory one step further though: Following their exit from Formula One racing last year, their whole engineering team expertise has been moved over to the maker's electric car program, to improve the electric breed.
50 ex-F1 engineers have migrated to BMWs EV program to ensure the German company retains their reputation for quality and performance even without fossil fuels.
Development chief Klaus Draeger says "The drivetrain is and will remain the heart of an automobile, and this goes for electric vehicles too... That’s why we’re developing the propulsion system for the Megacity Vehicle ourselves." Engineer Jochen Schroeder adds "The technology we’re developing for BMW is pretty similar to Formula One".
Both engineers clearly see their F1 experience as beneficial for the EV projects. Gone is the adrenaline of the high-octane race environment, replaced by considered strategic development and testing.

The BMW engineers certainly aren't the first to make the move from motorsports to EVs.
One notable engineer to have made the move from the red-hot to the green is South-African born Gordon Murray. Murray is best known for his work on Brabham and McLaren Formula One cars throughout the seventies, eighties and nineties, and his role in designing the McLaren F1 road car and the Mercedes-Benz SLR McLaren, both 200mph plus supercars known rather more for performance than economy.
Murray has moved from one extreme to the other though.
The engineer has now turned his talents to the T25 and T27 microcars. The former is gasoline powered, but the T27 will have an electric motor providing the power. Smaller than a Smart ForTwo, the T25 and T27 aren't just green vehicles but their "i-Stream" production is low energy too, as much as 80 percent less than regular car production.
The motorsport pedigree can be seen in the lightweight chassis, central driving position and economy of materials use, effectively getting the most from the least.

German sports car company Porsche wants to get in on the act too. In a good example of racing improving the breed, the company are using their 911 GT3-R Hybrid race car to develop techology that will eventually be seen in their road cars.
Using a regular gasoline powertrain coupled with electric motors powering the front wheels for extra traction and a kinetic energy recovery system (similar to that used by BMW's old F1 team) to recharge the hybrid's batteries. The car has been making quite an impact and raising the profile of electric technology in events such as the Petit Le Mans and the Nürburgring 24 Hours.
