Here’s Gizmag with the report:
Volkswagen rocked the automotive world at a lunchtime press conference on the first day of the Frankfurt Motor Show with a carbon fiber, half width, 1-liter hybrid electric diesel tandem two-seater car named the L1. When the car makes production in 2013, four years from now, it will almost certainly be the most fuel efficient car available with a combined diesel fuel consumption figure of 1.38 l/100km, thanks to its frugal motor combo, feather-like weight – 380 kg in total – and an aerodynamic drag co-efficient of just 0.195! – from Gizmag
