Volkswagen XL1 with sleek, lightweight body and construction was also one of first diesel plug-in hybrids in automotive history. With one charge of lithium-ion battery it could drive purely electric for up to 30 miles, but for all other drive scenarios, it was fitted with a combination of an electric motor and 800cc two-cylinder diesel engine, which were linked by a seven-speed dual-clutch transmission to the rear wheels.
Also the bodywork was more than just visually attractive. It was constructed from carbon fibre reinforced polymer with polycarbonate windows and weighted just 795 kilograms. It also allowed a respectful acceleration in 11.9 seconds to 100 km/h and the top speed was limited to 160 km/h.
