While in Anaheim last week covering the AFVI show, we got a chance to take the 2006 Smart Fortwo Brabus diesel conversion out for a spin. Robert Bosch Co. imported the vehicle down from Canada to demonstrate Bosch's diesel fuel injection technology but there's no implication they'll bring the vehicle to market any time soon. A gasoline fortwo is coming to the US in early 2008.
The fuel economy specs for the Brabus Smart fortwo are here (taken from the flyer handed out at AFVI). The standout numbers are 90 g/Km of CO2 and 56 mpg (European combined cycle). Technical details on the petrol Brabus Smart fortwo can be found on Smart's website.
