It’s apparently not that car makers can’t make cars with amazing fuel mileage. It’s that they don’t want to. Volkswagen has a concept, the EcoRacer, that is capable of getting up to 100 miles per gallon and yet can top out at 230 km/h. The turbo diesel engine can boost the car from 0 to 62 mph in just 6.3 seconds.
The car provides a great deal of flexibility in terms of looks. You can drive it as a coupe, remove the roof and rear window to make a roadster, or take off the windshield and upper dashboard cover to have a sporty speedster. When it is a coupe, wings in the roof lift up to make it easier to get in and out. Electromechanical technology lets you get in and go without a key. Most of the body of the car is made of carbon-fiber plastic. Sounds good, but it’s a concept, so don’t hold your breath, because you likely won’t ever see it.
