Speedometer accuracy and MT gear ratios

Tags: #speedometer · #mkpp

Speedometer scale and top speed by engine/transmission. The speedometer face is marked up to 240 km/h. Actual top-speed performance differs by engine and transmission: the naturally-aspirated CA4GD1 reaches 185 km/h with the manual transmission and 180 km/h with the automatic; the turbocharged CA4GC18T reaches 198 km/h. Across the range, the speedometer reads consistently 5-7% higher than actual road speed¹²³⁴⁵⁶.

Manual transmission (MКПП) gear ratio performance. Reported speed-at-RPM figures for the manual gearbox: 2nd gear — 75 km/h at 5000 RPM (satellite/GPS-verified), 90 km/h at 6000 RPM. 3rd gear — approximately 115 km/h at 5000 RPM (calculated) and ~138 km/h at 6000 RPM. The car has an electronic rev limiter to prevent over-revving; redline is near 6500 RPM, at which point the ECU cuts throttle to protect the drivetrain⁷⁸⁹¹⁰.
