Mercedes 3.0l v 2.2l (2006 onwards) (1 Viewer)

[MotorhomeMart]

Are the running costs between the 3.0l engine (OM642) massively different to the smaller 2.2l engine (OM646) ?

 

[Podney]

No,I don’t think they are.

The V6 is a bit thirsty but an absolute delight with the auto box. I probably get about 21-22 compared with a bit better for the smaller motor, but to be honest, in the great scheme of things it doesn’t really matter. At this level of spend, a few MPG is very small beans indeed

Yes the V6 is a cracking engine, plenty of torque & very smooth, we have one in our Mercedes R Class with 265bhp on tap & I can't fault it.
The trouble is that the 2.2 is a seriously good frugal lump.
I still lament the departure of the five cylinder 2.7 diesel.

full auto and 3.0l on our 5T Hymer 20mpg is very much the norm

18 if head wind, 21 if tail wind

we sit around 56mph on dual carriageways / motorways

3lt+autobox+ cruise control on 25-27mpg

3L V6 5.4t around 21mpg. Last van 2.8JTD Fiat 3.5t around 22mpg. Frontal area and cruising speed much more important than engine size. I cruise at (a genuine) 65mph. All the above A class vans.

Quantum tuning, had it done at Stoneleigh. £250 I think Have a look at there website.
I told my insurance company Saga and they noted on policy, no extra charge.

We used to have a Rapido 3850kg on 2.2auto.
Averaged 25 mpg and that include tramping up and down some serious mountains in Morocco.
