Along with the bubble-topped Trident, the P50 featured tricycle design and crude construction that made it the perfect conveyance for crowded cities (provided you were able to avoid collisions with vehicles and large pedestrians). Fitted with a 49cc DKW engine that could propel the little car to 37 mph, the original models had a three-speed manual transmission that had no reverse gear, forcing the driver to manhandle it around when necessary. Fuel economy, predictably, was quite good at 100 mpg and reliability was outstanding.
Following on the P50’s success, the bubble-topped Trident was launched in 1964 at Earl’s Court, with slightly larger dimensions that could accommodate two small adults. Production of both models resumed in 2010 with both electric and gas powered models, and improved suspension, steering and gearboxes. They are street legal in the United States and the Trident, especially, looks particularly cool for cruising around the town.
