22 cls450
I haven’t seen one post about the new CLS 450. This is the right forum? Supposedly getting mine in a few days once it gets off the transport truck.

Yes, this is the correct forum. Post VIN if you want MB data card.

Correct forum, the CLS is just sadly a very low volume model despite being excellent (although I'm clearly biased ), With the rise of SUV's, decrease in sedans and coupes, as well as redundant more popular models like the GT4D, the CLS is sadly destined for discontinuation in the US, so welcome to a very exclusive club. If you need any information on the car, a lot of its parts are directly shared with the W213 E-Class, and that forum is also more lively.

Thanks for the info.
Just got my 22!

Has anyone starting modding the M256 engine? and anyone know of any other differences between the 53's M256 spec and the 450 other than the additional e-compressor?
thanks!

currently moving around the C257 AMG, W213 AMG, W213 sedan groups, but it's still rather hard to find information directly related to the M256 engine. The W213 group is definitely the most lively but it's more on generic topics, the W213 AMG i see more on the 63 stuffs, and the C257 AMG is a dead town.

I believe the turbo size is also identical between the 450 and 53, although part numbers are different (but will confirm again through EPC)... if this is the case, highend power could be matched with tuning? Current stock boost for the 450 was measured at 0.75bar of boost (or about 11psi). Engine internals (part numbers) are exactly the same.

yup, i mentioned that... the e-compressor or e-supercharger..... i noted that the electric charger helps to minimize lag by pushing up boosting to about 0.5bar before the turbo takes over.

I am sorry about that, I don't know why my eye skipped over the word e-compressor but guess my brain was "programmed" to look for the word supercharger and match wasn't find, I apologize for that but ya since E 53 is amg-enhanced, there certainly are other changes under the hood by them or at least I expect other changes compared to regular mb branded engines. I too not sure what else is changed though, sorry about that.
at least good to know the engine internals are identical between the 53 and 450.
Yeah, i noticed some other accessory parts which are not in the 450 besides the e-charger.
back to research again...

Did anyone test drive the C257 450 FL and PFL and compared the ride comfort differences, if any? I am wondering if it is finally on par with the W213 and C238. As I did hear that the C257 pfl has a harsher riding suspension than the regular W213 and C238, 450 models.

Any findings? Admittedly I didn't find anything new.

Springs wise are part numbers belonging to the W213 variant.
Mine are the regular avant garde ones as i have the intent to switch to coilovers eventually...

i went ahead to check the suspension i had and it seems those with the regular avantgarde struts without adjustable damping shared the same W213 part, while those on variable damping and airmatic struts had part numbers only for the C257 (not shared with W213).

I'm gonna kick off my unusual projects soon and will look into either an upgraded hybrid turbo or a full aftermarket one (likely the BW EFR series).. lets see how it goes...

"This supercharger, which is located downstream of the turbocharger, uses a centrifugal flow compressor—like the compressor side of a turbo—driven by a 48-volt electric motor. It spins to 70,000 rpm and can develop a peak boost pressure of about 6.6 psi. "
"There’s a more conventional twin-scroll turbo on the other side of the M256 to do most of the heavy lifting, with peak boost of 29 psi. The electric compressor fills the gaps with about 7 pounds of boost as the conventional turbo builds steam."

Thanks again good luck and have fun with your projects and... boost pressure? Hmmm, I wonder if this article is accurate: https://www.caranddriver.com/news/a1...es-inline-six/
