The start: 0 to 100 km/h

Off the line, the M340i xDrive hits 100 km/h in 4.32 s versus 5.16 s for the 745e. Despite lacking instant torque, 382 hp of power compensates. At this point, the M340i xDrive leads by 0.84 s and sits roughly 13 m ahead.

From 100 km/h to 400 metres

At 200 metres, the M340i xDrive is doing 147 km/h against 139 km/h for the 745e. The gap is 0.68 s. The challenger starts to claw back ground.

At 400 metres standing start, the M340i xDrive crosses the line in 12.46 s versus 13.37 s. The 0.90 s gap represents roughly 43 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the M340i xDrive continues to build its lead. At 600 metres, it runs at 206 km/h versus 196 km/h. At 1,000 metres, the M340i xDrive finishes in 22.65 s versus 24.07 s, with a 1.43 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.

What the numbers don’t tell you

The M340i xDrive features all-wheel drive (AWD) against the 745e’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 share the same electronic speed cap: the 745e and the M340i xDrive are governed to 250 (i.e. 155 mph - industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

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 7.80 seconds. The 0.84 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
