The start: 0 to 100 km/h

Off the line, the i7 xDrive60 hits 100 km/h in 4.66 s versus 6.33 s for the A6 45 TFSI. The instant torque of 745 Nm from the electric motor makes the difference. At this point, the i7 xDrive60 leads by 1.67 s and sits roughly 14 m ahead.

From 100 km/h to 400 metres

At 200 metres, the i7 xDrive60 is doing 145 km/h against 128 km/h for the A6 45 TFSI. The gap is 1.11 s. The challenger starts to claw back ground.

At 400 metres standing start, the i7 xDrive60 crosses the line in 12.86 s versus 14.54 s. The 1.68 s gap represents roughly 72 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the i7 xDrive60 continues to build its lead. At 600 metres, it runs at 203 km/h versus 180 km/h. At 1,000 metres, the i7 xDrive60 finishes in 23.17 s versus 26.23 s, with a 3.06 s lead. Both vehicles have similar top speeds (240 vs 247 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the i7 xDrive60 is capped at 240 km/h, the A6 45 TFSI at 247 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 9.77 seconds. The 1.67 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
