|The talk of Frankfurt was the Volkswagen L1, a two-seater. This diesel-electric hybrid has a single door, weighs just 380kg and is made of aluminium and lightweight carbon fibre materials. The L1 has a stunning fuel economy of 189m/pg (100km/liter), tops out 110 m/hr, has a driving range of 416 miles with 39g/km of CO2. Available in 2013. This is serious competition for my favourite car, the Loremo.
