I’ve read that the E class offers improved fuel consumption, but I’m not sure how much difference the platform the engine is would really make.
As suggested the most comparable platforms I have is the W164 M156 versus W166 M157 which I run side by side and driven around 200,000 miles combined.
So that’s enough to average out the wrinkles of the occasional nightmare traffic jams, B-road blasts, thousand mile motorway trips, seasonal variation, etc.
The published stats are distorted by the use of stop-start in the test methods of the time, ie urban cycle 11.7 MPG versus 18.0 MPG, in the real world urban use is the same.
That said the figures for the extra urban (23.2 MPG versus 29.4 MPG) and combined (17.1 MPG versus 23.9 MPG) cycles are also distorted by stop-start.
I’m not commenting there on official verses real world because that should never be expected to be the same as that’s not the purpose of the official test.
I am commenting on the unrealistic differences between generations though. I hope that nobody ever buys an AMG based upon published figures!
I’ve never owned consecutive versions of the other models which featured both engines - so S/CL, SL and E/CLS - so I can’t make a reliable direct comparison.
