I have '94 C280 - just recently purchased. BMW's for years before. Here's the topic: What can I expect for rpm's at 70 mph? My tach shows just over 3100 rpm!? Maybe I'm used to having a 5-speed manual but this rpm seems excessive...
If this is the norm for a '94 C280, what can I expect for 100mph? 120 mph? I keep wanting to reach down and upshift at 70 mph! Somebody tell me this is normal...Thanks. |

Ok, its normal. No, really it is normal. My 300E will tach around 3300 RPM @ 75 mph.
Oh, and there is plenty of ass left in the engine @ 120mph.

Yup, your car is all good. You will hit about 4,000 @ 100. Then if you hit 5,000 you're pushing 120+, and it could run all day long at this speed!
It sometime annoys me too... but atleast you don't always have to downshift when passing on the hwy!

lookup the rpm at which your M104 engine develops max power. My guess is that your 4th gear ratio is designed such that the car reaches max speed at that rpm.

Max horsepower for the M104 2.8 liter is 195 @ 5500 RPM, though redline is 6400, I believe.
