MG4 Long Range RWD vs Atto 3 Extended Range: chronicle of a drag race at 180 km/h
The launch: 0 to 100 km/h
Off the line, the MG4 Long Range RWD hits 100 km/h in 6.73 s versus 7.41 s for the Atto 3 Extended Range. At this point, the MG4 Long Range RWD leads by 0.68 s and sits roughly 4 m ahead.
From 100 km/h to 400 metres
At 200 metres, the MG4 Long Range RWD is doing 129 km/h against 121 km/h for the Atto 3 Extended Range. The gap is 0.32 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 15.57 s. The 0.65 s gap represents roughly 26 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the MG4 Long Range RWD continues to build its lead. At 600 metres, it runs at 176 km/h versus 160 km/h. At 1,000 metres, the MG4 Long Range RWD finishes in 27.23 s versus 29.19 s, with a 1.96 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the MG4 Long Range RWD is capped at 180 km/h, the Atto 3 Extended Range 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.
With two electric powertrains, the difference comes down to power-to-weight ratio (7.00 kg/hp vs 8.58 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.71 seconds. The 0.68 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
MG MG4 Long Range RWD has a clear edge over the BYD Atto 3 Extended Range to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
