my benz 230e year 1989...3.5k rpm at 110km/h..I think the rpm is high because of the 4 speed automatic Gb and the weight of car which is 1850KG..

the weight I found in the bonet near the chasis number

As a matter of fact, what is the content inside the tyre doesn't effect the vehicle speed/engine speed but the circumference of the tyre (it's outer diameter to be easier understandind), allright this is only bout tyre. But offcourse is known to many of us here tht the transmission gear ratios play a big role.

My perdana V6 shows ~2800 revs at 110km/h.

To prove it:
Perdana v6 gear ratios:
Gear Ratio    1st  =  2.846
                        2nd  =  1.581
                        3rd  =  1.000
                        4th  =  0.685
Final Gear Ratio        =  4.350
110km/h change to meters/minutes = (110 x 1000) / 60
                                                    = 1833.3 meters/mins

Speed reduction at Final gear = 0.685 x 4.35
                                            = 2.979

Meaning 1 tire rotation equals 2.979 engine turns.

Tire circumference (stock perdana v6 205/55 R16) =  1.986 meters.

Tire revs per min = 1833 / 1.986
                          = 922.96 tire revolution / min

Engine revolution per min = 922.96 x 2.979
                                      = 2749 revs / mins

So the calculated engine revs is close the reading on the rev meter (-51 revs).

But that was when my auto gearbox is ok.
Now using manual gearbox becoz my auto box kong already.
Manual tranny reads 3100 @ 110 km/h.
Not sure what are the gear ratios on the manual tranny.

Does the calculation above applies to automatic box as well since it's using torque converter which means indirect drive unlike manual tranny tht is driven directly by the engine.
