Off the line, the 420d xDrive hits 100 km/h in 7.48 s versus 7.79 s for the A5 Sedan. At this point, the 420d xDrive leads by 0.31 s and sits roughly 9 m ahead.
At 200 metres, the 420d xDrive is doing 117 km/h against 117 km/h for the A5 Sedan. The gap is 0.34 s. The gap remains stable from the start.
At 400 metres standing start, the 420d xDrive crosses the line in 15.43 s versus 15.74 s. The 0.30 s gap represents roughly 12 m of track - two to three car lengths.
Past 400 metres, the 420d xDrive continues to build its lead. At 600 metres, it runs at 162 km/h versus 162 km/h. At 1,000 metres, the 420d xDrive finishes in 28.37 s versus 28.62 s, with a 0.25 s lead. Both vehicles have similar top speeds (242 vs 237 km/h), preventing any comeback.
The 420d xDrive features all-wheel drive (AWD) against the A5 Sedan’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 A5 Sedan is capped at 242 km/h, the 420d xDrive at 238 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 (8.92 kg/hp vs 8.79 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.41 seconds. The 0.31 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
