seems a little high, but not drastically. The tacho may not be 100% accurate.
These engines don’t have much torque down low and are designed to rev.

How can it be? Any advice appreciated

a small correction
The Differential Ratio
for 280 SEL 4.5
and 300 SEL 4.5
early with 3.23 should be 42:13

with kind regards
Jonas Gradin

I’m curious if it’s a Limited Slip. In my case, the rear diff has been replaced, so it’s not original to the car.
