Off the line, the Bmw M5 CS hits 100 km/h in 3.03 s versus 6.33 s for the A6 45 TFSI. At this point, the Bmw M5 CS leads by 3.30 s and sits roughly 19 m ahead.
At 200 metres, the Bmw M5 CS is doing 170 km/h against 128 km/h for the A6 45 TFSI. The gap is 2.54 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M5 CS crosses the line in 10.81 s versus 14.54 s. The 3.72 s gap represents roughly 154 m of track — a gap visible to the naked eye.
Past 400 metres, the Bmw M5 CS continues to build its lead. At 600 metres, it runs at 231 km/h versus 180 km/h. At 1,000 metres, the Bmw M5 CS finishes in 19.94 s versus 26.23 s, with a 6.29 s lead.
The Bmw M5 CS features all-wheel drive (AWD) against the A6 45 TFSI’s FWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Both rivals are electronically governed, but not at the same level: the Bmw M5 CS is capped at 305 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 (2.87 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 3.30 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.
