Off the line, the 911 Carrera (Manual) hits 100 km/h in 4.77 s versus 4.81 s for the Bmw X4 M40d. The 0.04 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the 911 Carrera (Manual) is doing 148 km/h against 138 km/h for the Bmw X4 M40d. The gap is 0.00 s. The gap remains stable from the start.
At 400 metres standing start, the 911 Carrera (Manual) crosses the line in 12.81 s versus 13.14 s. The 0.34 s gap represents roughly 16 m of track - two to three car lengths.
Past 400 metres, the 911 Carrera (Manual) continues to build its lead. At 600 metres, it runs at 209 km/h versus 192 km/h. At 1,000 metres, the 911 Carrera (Manual) finishes in 22.88 s versus 24.09 s, with a 1.21 s lead.
The Bmw X4 M40d features all-wheel drive (AWD) against the 911 Carrera (Manual)’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 911 Carrera (Manual) is capped at 289 km/h, the Bmw X4 M40d 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 (4.13 kg/hp vs 5.94 kg/hp) and transmission (Manual vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.57 seconds. The 0.04 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 911 Carrera (Manual) 991.1 and X4 M40d G02 are neck and neck (4,77 s vs 4,81 s, no significant gap).
911 Carrera (Manual) 991.1 goes from 0 to 100 km/h in 4,77 seconds (calibrated simulation).
