BMW iX M60 I20 vs Porsche 911 Carrera S (PDK) 991.1: which is truly faster?

Off the line, the iX M60 hits 100 km/h in 3.72 s versus 4.14 s for the 911 Carrera S (PDK). The instant torque of 1,100 Nm from the electric motor makes the difference. At this point, the iX M60 leads by 0.42 s and sits roughly 8 m ahead.

At 200 metres, the iX M60 is doing 151 km/h against 156 km/h for the 911 Carrera S (PDK). The gap is 0.27 s. The challenger starts to claw back ground.

At 400 metres standing start, the iX M60 crosses the line in 11.94 s versus 12.09 s. The 0.15 s gap represents roughly 8 m of track - barely a car length.

Past 400 metres, the situation changes. The iX M60 maxes out at 250 (i.e. 155 mph - industry threshold) km/h while the 911 Carrera S (PDK) keeps accelerating towards 297 km/h. At 600 metres, the gap has dropped to 0.05 s.

Around 719 metres, both vehicles are level. This is the inversion point: the 911 Carrera S (PDK) overcomes its launch deficit thanks to a 47 km/h higher top speed.

At 1,000 metres, the 911 Carrera S (PDK) finishes in 21.76 s versus 21.84 s. The 0.08 s delta shows an extremely tight race.

The iX M60 features all-wheel drive (AWD) against the 911 Carrera S (PDK)’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 iX M60 is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 911 Carrera S (PDK) at 300 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.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.01 seconds. The 0.42 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
