Off the line, the Bmw M135i xDrive hits 100 km/h in 4.78 s versus 5.07 s for the Boxster S. At this point, the Bmw M135i xDrive leads by 0.29 s and sits roughly 3 m ahead.
At 200 metres, the Bmw M135i xDrive is doing 144 km/h against 143 km/h for the Boxster S. The gap is 0.17 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M135i xDrive crosses the line in 13.00 s versus 13.18 s. The 0.18 s gap represents roughly 9 m of track - barely a car length.
Past 400 metres, the gap narrows. The Bmw M135i xDrive maxes out at 250 (i.e. 155 mph - industry threshold) km/h while the Boxster S keeps accelerating towards 272 km/h. At 600 metres, the gap has dropped to 0.17 s.
At 1,000 metres, the Bmw M135i xDrive finishes in 23.59 s versus 23.72 s, with just 0.13 s to spare. The Boxster S fails to fully close the launch gap.
The Bmw M135i xDrive features all-wheel drive (AWD) against the Boxster S’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 Boxster S is capped at 272 km/h, the Bmw M135i xDrive at 250 (i.e. 155 mph - industry threshold) 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 (4.39 kg/hp vs 4.98 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.54 seconds. The 0.29 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 5,07 s).
Boxster S 987 goes from 0 to 100 km/h in 5,07 seconds (calibrated simulation).
