The start: 0 to 100 km/h

Off the line, the A6 Sedan TFSI quattro S tronic 270 kW hits 100 km/h in 4.65 s versus 4.68 s for the Bmw M240i Coupé. The 0.04 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the A6 Sedan TFSI quattro S tronic 270 kW is doing 141 km/h against 149 km/h for the Bmw M240i Coupé. The gap is 0.02 s. The gap remains stable from the start.

At 400 metres standing start, the Bmw M240i Coupé crosses the line in 12.70 s versus 12.93 s. The 0.22 s gap represents roughly 11 m of track — two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Bmw M240i Coupé continues to build its lead. At 600 metres, it runs at 210 km/h versus 198 km/h. At 1,000 metres, the Bmw M240i Coupé finishes in 22.71 s versus 23.55 s, with a 0.83 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph — industry threshold) vs 250 (i.e. 155 mph — industry threshold) km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the Bmw M240i Coupé and the A6 Sedan TFSI quattro S tronic 270 kW are governed to 250 (i.e. 155 mph — industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold — an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

With two combustion powertrains, the difference comes down to power-to-weight ratio (4.37 kg/hp vs 5.40 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.22 seconds. The 0.04 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
