I think that the BMW i8 Concept is cool.
(Well, this/BMWi8 is an adsense displayed on the JWN)
"Acceleration of 0 to 100 km/h (62 mph) in under five seconds combined with fuel consumption in the European cycle of under three litres per 100 kilometres (approx. 94 mpg imp) are figures currently beyond the capability of any vehicle powered by a combustion engine of comparable performance."
