MUNICH, Germany (CNN) -- At first glance, the C-1 scooter looks like BMW crossed one of its auto assembly lines with one of its motorcycle plants.
Heads do turn as the hybrid scooter cruises European streets. It's marketed here as a commuter alternative to crowded public transportation -- and to the high costs of fueling a car, the equivalent of some U.S. $4 per gallon for gas these days. The C-1 is miserly by comparison, getting about 80 miles (128 km) per gallon of petrol.
