Engine RPM at highway cruising speed?

Northern335i · 01-01-2015, 08:43 PM

Hello all! How many RPMs are you running at 70mph indicated? What kind of mileage are you getting at a constant 70mph?

Thanks for your help!

DCT, I think just under 2K RPM and highway mileage was around 27-28 mpg.

DCT
2000-2200 RPM
24 to 26 mpg

I have MT, I think my RPM at 70MPH in 6th gear is closer to 3K. Others?

With an MT, at 3k, the car is traveling at 83 mph... That is what I set my cruise control to and get about 24-25 mpg

Ya much taller dct gearing than e92. It's too bad they cost cut and used m5 diff. A shorter final drive with bit taller 1st and 2nd heard would have made power to ground easier and more pull in 3rd

DCT 70 mph in 7th = 2060 RPM
6MT 70 mph in 6th = 2590 RPM

DCT 60 mph in 7th = 1760 RPM
6MT 60 mph in 6th = 2220 RPM
