Off the line, the M140i xDrive hits 100 km/h in 4.43 s versus 4.56 s for the 718 Cayman. At this point, the M140i xDrive leads by 0.13 s and sits roughly 3 m ahead.
At 200 metres, the M140i xDrive is doing 147 km/h against 149 km/h for the 718 Cayman. The gap is 0.09 s. The gap remains stable from the start.
At 400 metres standing start, the M140i xDrive crosses the line in 12.64 s versus 12.65 s. The 0.01 s gap represents roughly 1 m of track
Past 400 metres, the situation changes. The M140i xDrive maxes out at 250 (i.e. 155 mph - industry threshold) km/h while the 718 Cayman keeps accelerating towards 274 km/h. At 600 metres, the gap has dropped to 0.05 s.
Around 437 metres, both vehicles are level. This is the inversion point: the 718 Cayman overcomes its launch deficit thanks to a 24 km/h higher top speed.
At 1,000 metres, the 718 Cayman finishes in 22.89 s versus 23.01 s. The 0.12 s delta shows an extremely tight race.
The M140i xDrive features all-wheel drive (AWD) against the 718 Cayman’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 M140i xDrive is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 718 Cayman at 274 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 (4.53 kg/hp vs 4.45 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.70 seconds. The 0.13 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, M140i xDrive F20LCI wins (4,43 s vs 4,56 s).
M140i xDrive F20LCI goes from 0 to 100 km/h in 4,43 seconds (calibrated simulation).
