Off the line, the M240i Convertible hits 100 km/h in 4.66 s versus 5.81 s for the TT 45 TFSI. At this point, the M240i Convertible leads by 1.15 s and sits roughly 12 m ahead.
At 200 metres, the M240i Convertible is doing 145 km/h against 133 km/h for the TT 45 TFSI. The gap is 0.82 s. The challenger starts to claw back ground.
At 400 metres standing start, the M240i Convertible crosses the line in 12.85 s versus 14.06 s. The 1.22 s gap represents roughly 55 m of track - a gap visible to the naked eye.
Past 400 metres, the M240i Convertible continues to build its lead. At 600 metres, it runs at 201 km/h versus 184 km/h. At 1,000 metres, the M240i Convertible finishes in 23.31 s versus 25.49 s, with a 2.18 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 251 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the M240i Convertible 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 (4.88 kg/hp vs 5.43 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.89 seconds. The 1.15 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
