Off the line, the M340i xDrive Touring hits 100 km/h in 4.58 s versus 9.13 s for the 318d. At this point, the M340i xDrive Touring leads by 4.55 s and sits roughly 23 m ahead.
At 200 metres, the M340i xDrive Touring is doing 145 km/h against 109 km/h for the 318d. The gap is 2.35 s. The challenger starts to claw back ground.
At 400 metres standing start, the M340i xDrive Touring crosses the line in 12.74 s versus 16.56 s. The 3.82 s gap represents roughly 135 m of track - a gap visible to the naked eye.
Past 400 metres, the M340i xDrive Touring continues to build its lead. At 600 metres, it runs at 203 km/h versus 151 km/h. At 1,000 metres, the M340i xDrive Touring finishes in 23.11 s versus 30.51 s, with a 7.40 s lead.
The M340i xDrive Touring features all-wheel drive (AWD) against the 318d’s RWD. 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 Touring is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 318d at 210 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 (4.73 kg/hp vs 10.45 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 15.33 seconds. The 4.55 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M340i xDrive Touring G20 wins (4,58 s vs 9,13 s).
M340i xDrive Touring G20 goes from 0 to 100 km/h in 4,58 seconds (calibrated simulation).
