Off the line, the M340i xDrive hits 100 km/h in 4.32 s versus 7.72 s for the A5 Avant. At this point, the M340i xDrive leads by 3.40 s and sits roughly 31 m ahead.
At 200 metres, the M340i xDrive is doing 147 km/h against 122 km/h for the A5 Avant. The gap is 2.36 s. The challenger starts to claw back ground.
At 400 metres standing start, the M340i xDrive crosses the line in 12.46 s versus 15.70 s. The 3.24 s gap represents roughly 129 m of track - a gap visible to the naked eye.
Past 400 metres, the M340i xDrive continues to build its lead. At 600 metres, it runs at 206 km/h versus 172 km/h. At 1,000 metres, the M340i xDrive finishes in 22.65 s versus 27.94 s, with a 5.29 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 245 km/h), preventing any comeback.
The M340i xDrive 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 M340i xDrive 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 (4.77 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 3.40 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M340i xDrive G20 wins (4,32 s vs 7,72 s).
M340i xDrive G20 goes from 0 to 100 km/h in 4,32 seconds (calibrated simulation).
