Off the line, the M135i xDrive hits 100 km/h in 4.78 s versus 9.12 s for the 218d Convertible. At this point, the M135i xDrive leads by 4.34 s and sits roughly 21 m ahead.
At 200 metres, the M135i xDrive is doing 144 km/h against 109 km/h for the 218d Convertible. The gap is 2.25 s. The challenger starts to claw back ground.
At 400 metres standing start, the M135i xDrive crosses the line in 13.00 s versus 16.65 s. The 3.64 s gap represents roughly 130 m of track - a gap visible to the naked eye.
Past 400 metres, the M135i xDrive continues to build its lead. At 600 metres, it runs at 199 km/h versus 152 km/h. At 1,000 metres, the M135i xDrive finishes in 23.59 s versus 30.48 s, with a 6.89 s lead.
Both rivals are electronically governed, but not at the same level: the M135i xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 218d Convertible at 208 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 (4.98 kg/hp vs 10.43 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 15.20 seconds. The 4.34 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M135i xDrive F40 wins (4,78 s vs 9,12 s).
M135i xDrive F40 goes from 0 to 100 km/h in 4,78 seconds (calibrated simulation).
