The start: 0 to 100 km/h

Off the line, the M340d xDrive hits 100 km/h in 4.57 s versus 4.66 s for the i7 xDrive60. Despite lacking instant torque, 340 hp of power compensates. The 0.08 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the M340d xDrive is doing 140 km/h against 145 km/h for the i7 xDrive60. The gap is 0.15 s. The gap widens compared to the 0-100.

At 400 metres standing start, the i7 xDrive60 crosses the line in 12.86 s versus 12.86 s. The 0.01 s gap represents roughly 0 m of track

Beyond 400 metres: top speed comes into play

Past 400 metres, the i7 xDrive60 continues to build its lead. At 600 metres, it runs at 203 km/h versus 197 km/h. At 1,000 metres, the i7 xDrive60 finishes in 23.17 s versus 23.52 s, with a 0.35 s lead. Both vehicles have similar top speeds (240 vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.

What the numbers don’t tell you

The M340d xDrive 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 M340d xDrive 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 7.23 seconds. The 0.08 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
