Under the bonnet

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 3.92 s for the i4 M50 xDrive. At this point, the G6 leads by 0.12 s and sits roughly 3 m ahead.

From 100 km/h to 400 metres

At 200 metres, the G6 is doing 152 km/h against 155 km/h for the i4 M50 xDrive. The gap is 0.06 s. The gap remains stable from the start.

At 400 metres standing start, the i4 M50 xDrive crosses the line in 12.01 s versus 12.03 s. The 0.02 s gap represents roughly 1 m of track

Beyond 400 metres: top speed comes into play

Past 400 metres, the i4 M50 xDrive continues to build its lead. At 600 metres, it runs at 216 km/h versus 200 km/h. At 1,000 metres, the i4 M50 xDrive finishes in 21.97 s versus 22.89 s, with a 0.92 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the i4 M50 xDrive is capped at 225 km/h, the G6 at 200 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 (4.07 kg/hp vs 4.41 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.75 seconds. The 0.12 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
