Porsche Panamera 4 E-Hybrid 971 vs MG4 Long Range RWD: which is truly faster?

Off the line, the Panamera 4 E-Hybrid hits 100 km/h in 4.56 s versus 6.73 s for the 4 Long Range RWD. At this point, the Panamera 4 E-Hybrid leads by 2.18 s and sits roughly 25 m ahead.

At 200 metres, the Panamera 4 E-Hybrid is doing 143 km/h against 129 km/h for the 4 Long Range RWD. The gap is 1.55 s. The challenger starts to claw back ground.

At 400 metres standing start, the Panamera 4 E-Hybrid crosses the line in 12.86 s versus 14.92 s. The 2.05 s gap represents roughly 87 m of track - a gap visible to the naked eye.

Past 400 metres, the Panamera 4 E-Hybrid continues to build its lead. At 600 metres, it runs at 198 km/h versus 176 km/h. At 1,000 metres, the Panamera 4 E-Hybrid finishes in 23.49 s versus 27.23 s, with a 3.75 s lead.

The Panamera 4 E-Hybrid 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 Panamera 4 E-Hybrid is capped at 278 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 plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (4.93 kg/hp vs 7.00 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.07 seconds. The 2.18 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
