BMW X2 M35i F39 vs MG4 Long Range RWD: which is truly faster?

Off the line, the X2 M35i hits 100 km/h in 4.99 s versus 6.73 s for the 4 Long Range RWD. Despite lacking instant torque, 306 hp of power compensates. At this point, the X2 M35i leads by 1.74 s and sits roughly 23 m ahead.

At 200 metres, the X2 M35i is doing 138 km/h against 129 km/h for the 4 Long Range RWD. The gap is 1.27 s. The challenger starts to claw back ground.

At 400 metres standing start, the X2 M35i crosses the line in 13.30 s versus 14.92 s. The 1.61 s gap represents roughly 69 m of track - a gap visible to the naked eye.

Past 400 metres, the X2 M35i continues to build its lead. At 600 metres, it runs at 190 km/h versus 176 km/h. At 1,000 metres, the X2 M35i finishes in 24.37 s versus 27.23 s, with a 2.86 s lead.

The X2 M35i features all-wheel drive (AWD) against the 4 Long Range RWD’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 X2 M35i is capped at 250 (i.e. 155 mph - industry threshold) km/h, the 4 Long Range RWD at 180 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 10.07 seconds. The 1.74 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
