2012MY on have 10.4% better fuel economy!




This is due to the MCT transmission and a revised power steering pump.
10.4% is significant! I'll take it.




I drove a 2010 C63 26597km and averaged 6.588615km/l. My 2012 C63 has 31177km and I put on 8107km of those and averaged 6.590814km/l. That is an insignificant increase of 0.03%. YMMV
