Checking out some of the other threads, I saw the discussion regarding variable valve timing and the Crossfire engine. Not sure if anyone wants this little discussion, but here goes.

Basically the Xfire engine (and assorted other bits and pieces - only the good stuff I'm sure!) were sourced out of the Mercedes parts bins - many coming from the outgoing Mercedes SLK model. The engine is the same 3.2L, 3-valve/cylinder, 215 HP engine as was used in the "standard" version of the outgoing SLK. Bear in mind, however, that the SLK weighs in at 200+ pounds over the svelte Xfire and I believe the gearing was somewhat different (and of course WE have those lovely 19" wheels on the rear versus 17" for the Mercedes).

The SLK was also available with the AMG option engine - supercharged 3.2L producing 349 HP. As I understand it, this is the same engine that will be available in the SRT-6 version of the Xfire although slightly de-tuned. For what it's worth, the Xfire platform - thanks in part to the closed coupe structure - is much more rigid than the SLK and will be able to make full and effective use of the supercharged engine - something the SLK could apparently never do.

The new SLK is getting a 3.5L, 4-valve/cylinder engine producing 268HP in normal form and an optional V-8 will be available. Factor in, however, that the SLK will still be more than 200 pounds heavier than a comparable Xfire, and be about $10,000 more expensive!

Frankly I think the Xfire has one of the more beautiful designs on the road today and I certainly wouldn't trade mine - even straight across - for any SLK!
