## What is the E36 M3's gear ratio - BMW M3 MEDIASERVANT.INFO (E30 M3 | E36 M3 | E46 M3 | E92 M3 | F80/X)

Now, in physics, engineering, and design, as in many other fields, there are always multiple ways to arrive at the correct answer. Elegant explanations generally consist of the most basic examples which most clearly demonstrate the proof with a minimum of complexity. Ok, so we can solve this problem in any one of these ways: If we wanted actual time or distance separation, we would have to integrate the torque curves over time along with the gearing to get actual force derivatives.

That's why this ratio is so powerful and easy. You don't need the actual integration of the area under the curve. With axle ratios of 3. Call the distance factor d g or distance separation relative to gear with all of the distance units summed. We will make positive values the 4. That's why there are no units.

If you used actual derived integrated torque and mass, you could figure out the actual distances. Stage 2-Car A shifts to 2nd gear-ends at 40mph Even though the percentage advantage of Car B was greater in Scenario 2 than the advantage Car A had in Scenario 1, the time available was much shorter from 36 mph to 40 mph than from mph.

Stage 3-Car B shifts to 2nd gear-ends at 60mph The extra time in identical gears for the 4. Stage 4-Car A shifts to 3rd. Stage 5-Car B shifts to 3rd. Car A is now. Stage 6-Car A shifts to 4th. Notice however that on each chance that Car B has to do this, Car A is still slowly increasing it's advantage.

Stage 7-Car B shifts to 4th. Notice each even and each odd stage gap is increasing. Stage 8-Car A shifts to 5th.

Stage 9-Car B shifts to 5th. Stage Car A shifts to 6th. Stage Car B shifts to 6th. As a result, the total integration of acceleration over time is greater in the 4. Notice also that the outcome was partially dependent on the M3's ability to hold a gear for a long period of time ie. I could do a proof showing that for the M3's gearing, the optimum shift points are actually up in the rpm range depending on the gear change. Obviously an added shift, corner, or turbo car spool time etc.

The human body is pretty good at feeling force but not very good at feeling the integration or time of force. That's why quite often a turbo car will "feel" faster than an NA car of equal acceleration because of the torque peak or "hit" of the turbo.

Likewise, the added force in each gear of the 4. You won't notice the reduced time of the force in each gear as much. Since most people get an M3 for how it "feels", this is even more of a reason to go with a 4.
