Cruising at 3250 RPM would only give me 66 MPH so I'd need to drive at 3400 to get back to 70 MPH. If I were to start with 4.10:1 and move to 4.27 I would experience the opposite effect. It will be less noticeable in the first and second but as the gears go up the effect is more and more noticeable. In making the overall gearing longer I would have had quite an impact on the acceleration of the car. Turning around the maths would show us that putting a 3.64:1 diff in a 318iS would save around 350 RPM at motorway cruising. Using the above gearing calculator I can demonstrate:ДЇor 3250 RPM, 5th gear, 205/55/R15 wheels: The other thing to remember is that shorter gearing will mean higher engine revs for any given speed and longer gearing will mean lower revs for the same speed.

By contrast, a longer gearing (smaller number) will accelerate slower for any given gear. A shorter gearing (larger number) will make the car accelerate faster. The ratio will affect the performance characteristics of the car. A good gear calculator is on the Unixnerd site ] If we know the wheel size and gear box ratios as well as the final drive ratio we can work out road speed for any given engine speed. If the ratio is 1:1 then one turn of the prop-shaft would equal one turn of the wheels.

The ratio of a diff, often referred to as final drive, or final drive ratio, is last set of gears that the power goes through before hitting the wheels.
