Beginning with DaVinci’s spring-powered cart (c. 1478) and Nicolas Cugnot’s steam-powered wagon, Le Fardier a Vapeur (1769), non-gasoline powered automobiles have a long history. The Petersen Automotive Museum explores efforts – past, present, and future – to develop alternative power sources for automobiles. On display are electric vehicles from the early part of the 20th century and a hybrid gas-electric vehicle from 1916, the Woods Dual Power. We also show more recent fuel cell, turbine, and flexible fuel piston-driven engines. Finally, the focus will turn to the alternative power sources that are in development now and the direction scientific research will take in the future to develop cleaner running vehicles that run on renewable or abundant resources.
