Tesla Model S 85 vs BMW 540i xDrive Touring G30: which is truly faster?

Off the line, the 540i xDrive Touring hits 100 km/h in 5.07 s versus 5.75 s for the Model S 85. Despite lacking instant torque, 340 hp of power compensates. At this point, the 540i xDrive Touring leads by 0.67 s and sits roughly 14 m ahead.

At 200 metres, the 540i xDrive Touring is doing 140 km/h against 137 km/h for the Model S 85. The gap is 0.58 s. The gap remains stable from the start.

At 400 metres standing start, the 540i xDrive Touring crosses the line in 13.25 s versus 13.94 s. The 0.68 s gap represents roughly 32 m of track - a gap visible to the naked eye.

Past 400 metres, the 540i xDrive Touring continues to build its lead. At 600 metres, it runs at 195 km/h versus 190 km/h. At 1,000 metres, the 540i xDrive Touring finishes in 24.02 s versus 25.17 s, with a 1.15 s lead.

The 540i xDrive Touring features all-wheel drive (AWD) against the Model S 85’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 Model S 85 is capped at 201 km/h, the 540i xDrive Touring 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.

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 8.41 seconds. The 0.67 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
