Photos: Concept cars in China

The Mazda Senku concept car, making its Chinese premiere, features a cutting-edge powertrain and oversize, electrically operated flying-wing doors--but don't call it a DeLorean. The gasoline-powered rotary engine is complemented by a hybrid electric unit, and solar panels provide recharging for the batteries. The name "Senku" is a Japanese term that means "pioneer," Mazda says.
