Audi RS e-tron GT vs MG4 Long Range RWD: which is truly faster?

Off the line, the RS e-tron GT hits 100 km/h in 3.34 s versus 6.73 s for the 4 Long Range RWD. At this point, the RS e-tron GT leads by 3.39 s and sits roughly 23 m ahead.

At 200 metres, the RS e-tron GT is doing 167 km/h against 129 km/h for the 4 Long Range RWD. The gap is 2.59 s. The challenger starts to claw back ground.

At 400 metres standing start, the RS e-tron GT crosses the line in 11.17 s versus 14.92 s. The 3.75 s gap represents roughly 154 m of track - a gap visible to the naked eye.

Past 400 metres, the RS e-tron GT continues to build its lead. At 600 metres, it runs at 233 km/h versus 176 km/h. At 1,000 metres, the RS e-tron GT finishes in 20.27 s versus 27.23 s, with a 6.96 s lead.

The RS e-tron GT 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 RS e-tron GT 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.

With two electric powertrains, the difference comes down to power-to-weight ratio (3.25 kg/hp vs 7.00 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.07 seconds. The 3.39 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
