Manufacturer technical specifications. The power-to-weight ratio is the key physical factor in a drag race.

The start: 0 to 100 km/h

Off the line, the G6 hits 100 km/h in 3.80 s versus 7.44 s for the Bmw 420i. The instant torque of 660 Nm from the electric motor makes the difference. At this point, the G6 leads by 3.64 s and sits roughly 17 m ahead.

From 100 km/h to 400 metres

At 200 metres, the G6 is doing 152 km/h against 117 km/h for the Bmw 420i. 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 15.38 s. The 3.35 s gap represents roughly 128 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 163 km/h. At 1,000 metres, the G6 finishes in 22.89 s versus 28.23 s, with a 5.34 s lead. Despite a higher top speed (238 km/h), the Bmw 420i never recovers its launch deficit.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the G6 is capped at 200 km/h, the Bmw 420i at 240 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 12.15 seconds. The 3.64 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
