BMW i5 eDrive40 G60 vs BMW 330d xDrive G20: which is truly faster?

Off the line, the 330d xDrive hits 100 km/h in 5.17 s versus 6.12 s for the i5 eDrive40. Despite lacking instant torque, 265 hp of power compensates. At this point, the 330d xDrive leads by 0.95 s and sits roughly 21 m ahead.

At 200 metres, the 330d xDrive is doing 135 km/h against 135 km/h for the i5 eDrive40. The gap is 0.80 s. The challenger starts to claw back ground.

At 400 metres standing start, the 330d xDrive crosses the line in 13.48 s versus 14.29 s. The 0.81 s gap represents roughly 37 m of track - a gap visible to the naked eye.

Past 400 metres, the 330d xDrive continues to build its lead. At 600 metres, it runs at 188 km/h versus 186 km/h. At 1,000 metres, the 330d xDrive finishes in 24.66 s versus 25.87 s, with a 1.20 s lead.

The 330d xDrive features all-wheel drive (AWD) against the i5 eDrive40’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 i5 eDrive40 is capped at 193 km/h, the 330d 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 8.92 seconds. The 0.95 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
