The start: 0 to 100 km/h

Off the line, the M240i hits 100 km/h in 4.67 s versus 5.65 s for the A6 50 TDI quattro. The 0.99 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the M240i is doing 147 km/h against 129 km/h for the A6 50 TDI quattro. The gap is 0.54 s. The challenger starts to claw back ground.

At 400 metres standing start, the M240i crosses the line in 12.78 s versus 13.94 s. The 1.17 s gap represents roughly 51 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the M240i continues to build its lead. At 600 metres, it runs at 205 km/h versus 180 km/h. At 1,000 metres, the M240i finishes in 23.03 s versus 25.62 s, with a 2.59 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 M240i and the A6 50 TDI quattro 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 (4.49 kg/hp vs 6.54 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.15 seconds. The 0.99 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
