My first car was an '84 Cutlass, with the 307 V-8 and TH-200-C transmission. The R&P ratio on that car was 2.14:1. Yes, 2.14:1. I replaced that axle with a posi axle out of a Grand Prix, and although it was advertised as a 2.41:1 ratio, I think it was really 2.29:1.

The final drive in my '04 subaru legacy is 4.10. This thing will turn 3000 rpm at 70 mph in 5th gear. Its awesome gearing for mountainous driving, not so much for open highway.

3.84 for the Cobalt 4.44 for the Outback? That 4.44 seems pretty high (numerically) to me. Engine revs in OD are about the same as the Cobalt - around 2500 @ 65mph.

I looked back at this and with the differences in wheel diameter (195/60/R15 for the Cobalt vs. 225/55/R17 for the Outback) it works out to be very close.

A discussion about gear ratios cannot include engine revs at speed without also including the transmission ratios. For example, my two Honda products have pretty short final drive gearing, but have pretty tall 5th gears in the transaxles (close to 0.56:1 in both). So engine speeds at higher road speeds are reasonable. The Honda is 2,100 rpm at 70 mph. The Acura is 1,900 rpm at 70 mph.
