Lexus IS 300 AWD vs MG MG4 Long Range RWD: which is truly faster?

Off the line, the MG4 Long Range RWD hits 100 km/h in 6.73 s versus 7.70 s for the IS 300 AWD. The instant torque of 350 Nm from the electric motor makes the difference. At this point, the MG4 Long Range RWD leads by 0.97 s and sits roughly 10 m ahead.

At 200 metres, the MG4 Long Range RWD is doing 129 km/h against 122 km/h for the IS 300 AWD. The gap is 0.55 s. The challenger starts to claw back ground.

At 400 metres standing start, the MG4 Long Range RWD crosses the line in 14.92 s versus 15.66 s. The 0.74 s gap represents roughly 31 m of track - a gap visible to the naked eye.

Past 400 metres, the gap narrows. The MG4 Long Range RWD maxes out at 180 km/h while the IS 300 AWD keeps accelerating towards 210 km/h. At 600 metres, the gap is down to 0.83 s from 0.74 s at 400 metres.

At 1,000 metres, the MG4 Long Range RWD finishes in 27.23 s versus 27.75 s, with just 0.52 s to spare. The IS 300 AWD fails to fully close the launch gap.

Both rivals are electronically governed, but not at the same level: the IS 300 AWD is capped at 210 km/h, the MG4 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 11.57 seconds. The 0.97 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
