Off the line, the Bmw 840i hits 100 km/h in 5.12 s versus 5.81 s for the TT 45 TFSI. At this point, the Bmw 840i leads by 0.69 s and sits roughly 7 m ahead.
At 200 metres, the Bmw 840i is doing 140 km/h against 133 km/h for the TT 45 TFSI. The gap is 0.47 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 840i crosses the line in 13.33 s versus 14.06 s. The 0.73 s gap represents roughly 33 m of track — a gap visible to the naked eye.
Past 400 metres, the Bmw 840i continues to build its lead. At 600 metres, it runs at 196 km/h versus 184 km/h. At 1,000 metres, the Bmw 840i finishes in 24.04 s versus 25.49 s, with a 1.45 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 840i 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 (5.20 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 0.69 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
