Same shit as the 0.5l challenge, but on east coast usa Highway. Set Cruise control to 90 kmh (Or 55 mph for americans) I done 6.6 km with a diesel d series with bed, door panles and mirrors removed.
19.2km with stock covet 1.5DX. didnt even passed 3 in the rpm gauge at all the time ---------------------------------------------------------------------------------------------------------------------------- 21.2km/l with stock covet DXi. 5th overdrive gear and Fuel injection seems make covet go 3km more per liter than DX.
