Off the line, the Bmw Z4 M40i hits 100 km/h in 4.54 s versus 5.81 s for the TT 45 TFSI. At this point, the Bmw Z4 M40i leads by 1.27 s and sits roughly 12 m ahead.
At 200 metres, the Bmw Z4 M40i is doing 147 km/h against 133 km/h for the TT 45 TFSI. The gap is 0.90 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw Z4 M40i crosses the line in 12.70 s versus 14.06 s. The 1.37 s gap represents roughly 61 m of track — a gap visible to the naked eye.
Past 400 metres, the Bmw Z4 M40i continues to build its lead. At 600 metres, it runs at 205 km/h versus 184 km/h. At 1,000 metres, the Bmw Z4 M40i finishes in 22.95 s versus 25.49 s, with a 2.54 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 Bmw Z4 M40i 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 (4.51 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 1.27 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
