Off the line, the TT 45 TFSI hits 100 km/h in 5.81 s versus 7.44 s for the Bmw 420i. At this point, the TT 45 TFSI leads by 1.63 s and sits roughly 5 m ahead.
At 200 metres, the TT 45 TFSI is doing 133 km/h against 117 km/h for the Bmw 420i. The gap is 0.67 s. The challenger starts to claw back ground.
At 400 metres standing start, the TT 45 TFSI crosses the line in 14.06 s versus 15.38 s. The 1.32 s gap represents roughly 52 m of track - a gap visible to the naked eye.
Past 400 metres, the TT 45 TFSI continues to build its lead. At 600 metres, it runs at 184 km/h versus 163 km/h. At 1,000 metres, the TT 45 TFSI finishes in 25.49 s versus 28.23 s, with a 2.74 s lead. Both vehicles have similar top speeds (251 (i.e. 155 mph - industry threshold) vs 238 km/h), preventing any comeback.
Electronically capped at 240 km/h, the Bmw 420i 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 (5.43 kg/hp vs 8.29 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.15 seconds. The 1.63 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, TT 45 TFSI wins (5,81 s vs 7,44 s).
TT 45 TFSI goes from 0 to 100 km/h in 5,81 seconds (calibrated simulation).
