Hey guys...don't know much about Benz's and the new C has really caught my eye.

Can you guys tell me if the HP ratings for the C (or all of Mercedes in general) is measured at the crank or at the wheel? Most auto makers do it at the crank with the exception of BMW (that I know of). I'm currently pushing about 240 at the crank in my VW and need to know if I need the C350 for an increase.

Thanks in advance for your response.

Sorry but all automakers tell you how much power is being made at the crank. I can tell you that the M5 does not make 500hp at the wheels. If it did, it would romp on most cars ever made.

MBZ measures at the crank.

Thanks for the response.

Well I remember hearing that but it must have not been a credible source. Although I did come across this article regarding a 335i dyno that said it peaked at 300 at the wheels. I thought I remember BMW's site having it listed as 300.

Could be a real happy dyno too I guess.

Thanks for the info.

335i is simply underrated.

I seem recall the 335i putting 300 ponies at the crank and ~275 at the rear wheels. I think the torque was the same at 275 which is fairly impressive since most cars seem to loose 10-20% when measured at the wheels, the 335i is loosing less than 10%.

I haven't found any reliable dyno reports on the new C350 yet. I did see a post on another site where a C350 owner said he installed Kleemann headers and Eisenmann racing exhaust and dyno'd out at 325hp & 315 torque at the wheels. He said he killed a 335i. Not sure if I buy that, seems like A LOT of gain for headers and exhaust. But I liked the killing part

it's not that the loss is low, the twin-turbo I6 is underrated.

The 335i is making around 340hp at the CRANK. The loss is not low, the engine is simply making more power than what is being advertised.

Right on.
