Audi RS 5 Sedan vs BMW M2 G87: which is truly faster?

Off the line, the RS 5 Sedan hits 100 km/h in 3.73 s versus 4.12 s for the M2. The instant torque of 825 Nm from the electric motor makes the difference. At this point, the RS 5 Sedan leads by 0.39 s and sits roughly 6 m ahead.

At 200 metres, the RS 5 Sedan is doing 156 km/h against 155 km/h for the M2. The gap is 0.28 s. The challenger starts to claw back ground.

At 400 metres standing start, the RS 5 Sedan crosses the line in 11.77 s versus 12.08 s. The 0.31 s gap represents roughly 16 m of track - two to three car lengths.

Past 400 metres, the RS 5 Sedan continues to build its lead. At 600 metres, it runs at 218 km/h versus 215 km/h. At 1,000 metres, the RS 5 Sedan finishes in 21.38 s versus 21.80 s, with a 0.43 s lead. Despite a higher top speed (285 km/h), the M2 never recovers its launch deficit.

The RS 5 Sedan features all-wheel drive (AWD) against the M2’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.

Both rivals are electronically governed, but not at the same level: the RS 5 Sedan is capped at 250 (i.e. 155 mph - industry threshold) km/h, the M2 at 285 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.94 seconds. The 0.39 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
