BMW i7 xDrive60 G70 vs Porsche 2013 Panamera GTS: which is truly faster?

Off the line, the 2013 Panamera GTS hits 100 km/h in 4.48 s versus 4.66 s for the i7 xDrive60. Despite lacking instant torque, 430 hp of power compensates. At this point, the 2013 Panamera GTS leads by 0.18 s and sits roughly 3 m ahead.

At 200 metres, the 2013 Panamera GTS is doing 147 km/h against 145 km/h for the i7 xDrive60. The gap is 0.13 s. The gap remains stable from the start.

At 400 metres standing start, the 2013 Panamera GTS crosses the line in 12.69 s versus 12.86 s. The 0.17 s gap represents roughly 9 m of track - barely a car length.

Past 400 metres, the 2013 Panamera GTS continues to build its lead. At 600 metres, it runs at 205 km/h versus 203 km/h. At 1,000 metres, the 2013 Panamera GTS finishes in 22.94 s versus 23.17 s, with a 0.23 s lead.

The 2013 Panamera GTS features all-wheel drive (AWD) against the i7 xDrive60’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 i7 xDrive60 is capped at 240 km/h, the 2013 Panamera GTS at 288 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 6.94 seconds. The 0.18 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
