Off the line, the M5 CS hits 100 km/h in 3.03 s versus 7.73 s for the A5 Avant. At this point, the M5 CS leads by 4.70 s and sits roughly 21 m ahead.
At 200 metres, the M5 CS is doing 170 km/h against 117 km/h for the A5 Avant. The gap is 3.18 s. The challenger starts to claw back ground.
At 400 metres standing start, the M5 CS crosses the line in 10.81 s versus 15.68 s. The 4.86 s gap represents roughly 180 m of track - a gap visible to the naked eye.
Past 400 metres, the M5 CS continues to build its lead. At 600 metres, it runs at 231 km/h versus 162 km/h. At 1,000 metres, the M5 CS finishes in 19.94 s versus 28.61 s, with a 8.67 s lead.
The M5 CS features all-wheel drive (AWD) against the A5 Avant’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 M5 CS is capped at 305 km/h, the A5 Avant at 240 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 9.00 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.40 seconds. The 4.70 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M5 CS F90 wins (3,03 s vs 7,73 s).
M5 CS F90 goes from 0 to 100 km/h in 3,03 seconds (calibrated simulation).
