Gear Ratio & Speed
Type in your gearbox ratios, final drive and tyre size — see the speed each gear reaches at redline, plus cruising rpm at 60 and 100 km/h.

Good to know
- Speeds assume a manual/auto gear ratio list from 1st to top gear, in order.
- Real speed at high rpm depends on tyre growth, clutch/converter slip and drivetrain losses — expect a few percent either way.
- Cruising rpm tells you a lot: below ~2,200 rpm is relaxed highway gearing, above ~3,000 rpm gets thirsty.
