Audi e-tron GT quattro vs BMW M3 Competition Sedan G80: which is truly faster?

Off the line, the Bmw M3 Competition Sedan hits 100 km/h in 3.88 s versus 4.14 s for the e-tron GT quattro. Despite lacking instant torque, 510 hp of power compensates. The 0.26 s gap is negligible: both vehicles are neck and neck.

At 200 metres, the Bmw M3 Competition Sedan is doing 163 km/h against 149 km/h for the e-tron GT quattro. The gap is 0.32 s. The gap remains stable from the start.

At 400 metres standing start, the Bmw M3 Competition Sedan crosses the line in 11.64 s versus 12.36 s. The 0.72 s gap represents roughly 36 m of track — a gap visible to the naked eye.

Past 400 metres, the Bmw M3 Competition Sedan continues to build its lead. At 600 metres, it runs at 228 km/h versus 208 km/h. At 1,000 metres, the Bmw M3 Competition Sedan finishes in 20.91 s versus 22.46 s, with a 1.54 s lead. Both vehicles have similar top speeds (245 vs 250 (i.e. 155 mph — industry threshold) km/h), preventing any comeback.

Both rivals are electronically governed, but not at the same level: the e-tron GT quattro is capped at 245 km/h, the Bmw M3 Competition Sedan at 250 (i.e. 155 mph — industry threshold) 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 6.28 seconds. The 0.26 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
