I didn't notice this until a friend of mine pointed this out to me, but if I'm cruising in 5th gear at 80MPH, is my engine supposed to be spinning at 4000RPMs? At ~45MPH, it's rotating at about 2400RPMs. Now I know this my be a different car, but in the 5SFE auto Camry that I used to drive, 2000RPMs at the highest gear was 50MPH. Anyone else with a GT notice this or is it just me?

Go look up the gear ratios for the transmission used in your Celica... the answer is in the gear ratios. The transmission is selected based on available HP of the engine, where the power band of that engine resides, the required torque in ft-lbs for the vehicle and the desired top speed.
Other factors play in transmission selection , like a "sporty feel" where the manuafacturer wants the engine to rev higher inthe power band prior to the shift point. This post has been edited by Rangemaster: Dec 10, 2006 - 11:02 PM |
