Average RPM at 100 kmh?

[torontodude]

Hi,

I have a 2001 C320. I am wondering what are the RPMs suppose to be when cruising at 100 km/h on the highway. My car turns about 2500 - 3000. I am wondering if this is normal as it seems to me a bit high for a V6. I also have 97 C230 which revs about the same.

Thanks

Nope.. thats completely normal... only in a V8 will you notice the lower revs at highway speeds... Mercedes keeps the torque on demand in that range so you can pass on the freeway with ease.

mine is less than 2500 rpm if the road is relatively level. some uphills won't change it either.
