Off the line, the Bmw 540i hits 100 km/h in 5.20 s versus 6.33 s for the A6 45 TFSI. At this point, the Bmw 540i leads by 1.13 s and sits roughly 11 m ahead.
At 200 metres, the Bmw 540i is doing 141 km/h against 128 km/h for the A6 45 TFSI. The gap is 0.76 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 540i crosses the line in 13.32 s versus 14.54 s. The 1.22 s gap represents roughly 53 m of track - a gap visible to the naked eye.
Past 400 metres, the Bmw 540i continues to build its lead. At 600 metres, it runs at 199 km/h versus 180 km/h. At 1,000 metres, the Bmw 540i finishes in 23.90 s versus 26.23 s, with a 2.33 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 247 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the Bmw 540i is capped at 250 (i.e. 155 mph - industry threshold) km/h, the A6 45 TFSI at 247 km/h. This isn’t a physical engine limit - it’s a manufacturer choice, usually for tyre safety or homologation reasons. Neither car reaches its true aerodynamic top speed.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.69 kg/hp vs 6.69 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.77 seconds. The 1.13 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Swap one of the two models to explore an equivalent duel in the same segment.
