Off the line, the M340i xDrive hits 100 km/h in 4.32 s versus 8.33 s for the 318i. At this point, the M340i xDrive leads by 4.01 s and sits roughly 24 m ahead.
At 200 metres, the M340i xDrive is doing 147 km/h against 113 km/h for the 318i. The gap is 2.29 s. The challenger starts to claw back ground.
At 400 metres standing start, the M340i xDrive crosses the line in 12.46 s versus 16.06 s. The 3.60 s gap represents roughly 132 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 157 km/h. At 1,000 metres, the M340i xDrive finishes in 22.65 s versus 29.44 s, with a 6.79 s lead.
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 318i at 223 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 9.55 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 13.71 seconds. The 4.01 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 8,33 s).
M340i xDrive G20 goes from 0 to 100 km/h in 4,32 seconds (calibrated simulation).
