The start: 0 to 100 km/h

Off the line, the M140i hits 100 km/h in 4.54 s versus 6.21 s for the A3 Sedan. At this point, the M140i leads by 1.67 s and sits roughly 4 m ahead.

From 100 km/h to 400 metres

At 200 metres, the M140i is doing 151 km/h against 119 km/h for the A3 Sedan. The gap is 1.01 s. The challenger starts to claw back ground.

At 400 metres standing start, the M140i crosses the line in 12.60 s versus 14.73 s. The 2.13 s gap represents roughly 85 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the M140i continues to build its lead. At 600 metres, it runs at 210 km/h versus 169 km/h. At 1,000 metres, the M140i finishes in 22.65 s versus 27.19 s, with a 4.54 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 241 km/h), preventing any comeback.

What the numbers don’t tell you

Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the M140i never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

With two combustion powertrains, the difference comes down to power-to-weight ratio (4.32 kg/hp vs 7.13 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.24 seconds. The 1.67 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
