Off the line, the M135i xDrive hits 100 km/h in 4.78 s versus 6.54 s for the 225d Convertible. At this point, the M135i xDrive leads by 1.76 s and sits roughly 15 m ahead.
At 200 metres, the M135i xDrive is doing 144 km/h against 127 km/h for the 225d Convertible. The gap is 1.16 s. The challenger starts to claw back ground.
At 400 metres standing start, the M135i xDrive crosses the line in 13.00 s versus 14.76 s. The 1.76 s gap represents roughly 74 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 175 km/h. At 1,000 metres, the M135i xDrive finishes in 23.59 s versus 26.79 s, with a 3.20 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 225d Convertible at 231 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 7.25 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.18 seconds. The 1.76 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 6,54 s).
M135i xDrive F40 goes from 0 to 100 km/h in 4,78 seconds (calibrated simulation).
M135i xDrive F40: 306 hp, ratio 4,98 kg/hp. 225d Convertible F22: 224 hp, ratio 7,25 kg/hp.
M135i xDrive F40: 250 km/h. 225d Convertible F22: 231 km/h.
