My 350 engine same as CLS or SLK?

[A210AMG]

Hello,

Currently have a M-class (350), is this the same engine as in a CLS or SLK?
think mine has 240bhp and the CLS / SLK has 270
If its the same can mine be 'remapped'

Thanks

Are you talking about the W163 ML or the new W164 ML?

The CLS and SLK both have a new generation 3.5 litre V6 engine - as does the new W164 ML350.

Whereas the older W163 ML came with a previous generation 3.7 litre V6 engine (despite the 350 name tag).

Hope this helps.
