Mercedes CLA 250+ with EQ technology 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 6.83 s for the CLA 250+ with EQ technology. The 0.10 s gap is negligible: both vehicles are neck and neck.

At 200 metres, the MG4 Long Range RWD is doing 129 km/h against 128 km/h for the CLA 250+ with EQ technology. The gap is 0.05 s. The gap remains stable from the start.

At 400 metres standing start, the MG4 Long Range RWD crosses the line in 14.92 s versus 15.00 s. The 0.08 s gap represents roughly 4 m of track — barely a car length.

Past 400 metres, the situation changes. The MG4 Long Range RWD maxes out at 180 km/h while the CLA 250+ with EQ technology keeps accelerating towards 210 km/h. At 600 metres, the gap has dropped to 0.09 s.

Around 800 metres, both vehicles are level. This is the inversion point: the CLA 250+ with EQ technology overcomes its launch deficit thanks to a 30 km/h higher top speed.

At 1,000 metres, the CLA 250+ with EQ technology finishes in 26.90 s versus 27.23 s. The 0.34 s delta shows an extremely tight race.

Both rivals are electronically governed, but not at the same level: the CLA 250+ with EQ technology 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.

With two electric powertrains, the difference comes down to power-to-weight ratio (7.56 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 10.25 seconds. The 0.10 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
