Electricity is the once and future drivetrain for automobiles, but until the advent of lithium batteries their capabilities were somewhat modest. One EV blip on the automotive timeline is the XP-512E commuter prototype by GM.
The 60s saw a wide variety of interesting experiments in the automobile space, and both GM and AMC were evaluating the possibilities of a return to electric cars for short journeys. GM wasn’t set on a particular drivetrain for their new experimental commuter cars, so the XP 512 became a trio with conventional, hybrid, and electric variants. Each car was a two seater with a fiberglass body and steel chassis. The canopy could lift and a small door in the front swung to the side for access to the cockpit. Some images from the time show the car without the canopy and just the rollbar, giving you a very small convertible (83″/2108 mm long).
Lead acid was the only viable traction battery until the 1990s, so the 1,250 lb vehicle was limited to a top speed of 30 mph and a range of 50 miles. GM was exploring a number of alternatives at the time including another blast from the automotive past, steam power, in an effort to reduce the issues of smog and air pollution that plagued cities beset by droves of V-8 powered sedans. While the XP-512E and the AMC Amitron never made it to production, they’re an interesting reminder that technologies that seem infeasible today may just need to bake a bit longer.
We have some thoughts about the opportunities afforded by electric cars, but it’s probably a good thing we didn’t get nuclear powered automobiles.
