The start: 0 to 100 km/h

Off the line, the G6 hits 100 km/h in 3.80 s versus 6.73 s for the 4 Long Range RWD. At this point, the G6 leads by 2.93 s and sits roughly 25 m ahead.

From 100 km/h to 400 metres

At 200 metres, the G6 is doing 152 km/h against 129 km/h for the 4 Long Range RWD. The gap is 2.12 s. The challenger starts to claw back ground.

At 400 metres standing start, the G6 crosses the line in 12.03 s versus 14.92 s. The 2.89 s gap represents roughly 121 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the G6 continues to build its lead. At 600 metres, it runs at 200 km/h versus 176 km/h. At 1,000 metres, the G6 finishes in 22.89 s versus 27.23 s, with a 4.34 s lead.

What the numbers don’t tell you

The G6 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 G6 is capped at 200 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 (4.41 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 2.93 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
