The Technical University of Munich (TUM) and its TUfast Eco Team took its teardrop-shaped electric vehicle out to Audi's test track in Bavaria earlier this month to see how far it could go on as little electric power as possible. With a few tweaks here and there, the TUfast team took the little-bitty vehicle around the Audi track's banked turns and achieved an efficiency rate of more than 1,200 kilometers per kilowatt hour. Convert that to miles per gallon-equivalent, and you have a vehicle that gets the equivalent of about 26,100 miles per gallon. That's good for a Guinness Record for energy efficiency out of a vehicle.
The nine-member team took its vehicle to the European version of the Shell Eco-marathon in London earlier this month, and posted a video on its entry. In fact, the car was originally built for the 2014 Shell Eco-marathon, and has been improved since then.
Granted, the car can't be compared to the garden-variety light-duty vehicle. The three-wheeled car is dwarfed by the size of a typical road vehicle, while the car's single occupant drives it by practically lying down. Meanwhile, updates during the past year include super-aerodynamic rims, low-friction bearings, and a tweak in the magnet placement in the vehicle's electric motor.
