The start: 0 to 100 km/h

Off the line, the SQ6 SUV e-tron hits 100 km/h in 4.37 s versus 7.74 s for the 420i xDrive. The instant torque of 855 Nm from the electric motor makes the difference. At this point, the SQ6 SUV e-tron leads by 3.38 s and sits roughly 16 m ahead.

From 100 km/h to 400 metres

At 200 metres, the SQ6 SUV e-tron is doing 144 km/h against 115 km/h for the 420i xDrive. The gap is 1.80 s. The challenger starts to claw back ground.

At 400 metres standing start, the SQ6 SUV e-tron crosses the line in 12.70 s versus 15.61 s. The 2.91 s gap represents roughly 110 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the SQ6 SUV e-tron continues to build its lead. At 600 metres, it runs at 198 km/h versus 160 km/h. At 1,000 metres, the SQ6 SUV e-tron finishes in 23.29 s versus 28.71 s, with a 5.43 s lead. Both vehicles have similar top speeds (230 vs 234 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the SQ6 SUV e-tron is capped at 230 km/h, the 420i xDrive at 238 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 12.85 seconds. The 3.38 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
