BMW 430i xDrive Gran Coupe G22 vs Audi A5 Avant: which is truly faster?

Off the line, the 430i xDrive Gran Coupe hits 100 km/h in 5.81 s versus 7.72 s for the A5 Avant. At this point, the 430i xDrive Gran Coupe leads by 1.91 s and sits roughly 28 m ahead.

At 200 metres, the 430i xDrive Gran Coupe is doing 130 km/h against 122 km/h for the A5 Avant. The gap is 1.37 s. The challenger starts to claw back ground.

At 400 metres standing start, the 430i xDrive Gran Coupe crosses the line in 14.04 s versus 15.70 s. The 1.67 s gap represents roughly 68 m of track - a gap visible to the naked eye.

Past 400 metres, the 430i xDrive Gran Coupe continues to build its lead. At 600 metres, it runs at 181 km/h versus 172 km/h. At 1,000 metres, the 430i xDrive Gran Coupe finishes in 25.67 s versus 27.94 s, with a 2.27 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 245 km/h), preventing any comeback.

The 430i xDrive Gran Coupe 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 430i xDrive Gran Coupe is capped at 250 (i.e. 155 mph - industry threshold) km/h, the A5 Avant at 245 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 (6.51 kg/hp vs 8.38 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.72 seconds. The 1.91 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
