MB GL400 vs. GL400 Coupe

[boof777]

MB have released their new 2016 GL class SUV in traditional wagon and 4-door Coupe versions.

What I found interesting was the two different rooflines. So I looked up the fuel consumption figures for both models in the GL400 class (twin turbo V6 gasoline engine with auto and AWD).

So MB has quoted the 'slippery' Coupe as only 0.1lt per 100km better on the combined cycle. I know the difference would be noticed more at highway speeds, but I couldn't find a highway only figure for the upcoming Coupe version.

Would have thought the better aero shape of the Coupe might have yielded a bigger difference even in the combined cycle??

Still, at 8.8lt (Wagon) vs. 8.7lt (Coupe) per 100km its hardly a thirsty SUV. Albeit, claimed manufacturers figures ;-)
