BMW 420i xDrive G22 vs MINI Cooper E FWD: which is truly faster?

Off the line, the Cooper E FWD hits 100 km/h in 7.20 s versus 7.74 s for the Bmw 420i xDrive. The instant torque of 290 Nm from the electric motor makes the difference. Despite the faster sprint time, the Bmw 420i xDrive is 9 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.

At 200 metres, the Bmw 420i xDrive is doing 115 km/h against 124 km/h for the Cooper E FWD. The gap is 0.13 s. The challenger starts to claw back ground.

At 400 metres standing start, the Cooper E FWD crosses the line in 15.37 s versus 15.61 s. The 0.24 s gap represents roughly 9 m of track - barely a car length.

Past 400 metres, the situation changes. The Cooper E FWD maxes out at 160 km/h while the Bmw 420i xDrive keeps accelerating towards 234 km/h. At 600 metres, the gap has dropped to 0.42 s.

Around 918 metres, both vehicles are level. This is the inversion point: the Bmw 420i xDrive overcomes its launch deficit thanks to a 74 km/h higher top speed.

At 1,000 metres, the Bmw 420i xDrive finishes in 28.71 s versus 28.93 s. The 0.21 s delta shows an extremely tight race.

The Bmw 420i xDrive features all-wheel drive (AWD) against the Cooper E FWD’s FWD. 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 Bmw 420i xDrive is capped at 238 km/h, the Cooper E FWD at 160 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 12.85 seconds. The 0.54 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
