The start: 0 to 100 km/h

Off the line, the i7 M70 xDrive hits 100 km/h in 3.65 s versus 4.64 s for the S3 Sportback. The instant torque of 1,015 Nm from the electric motor makes the difference. At this point, the i7 M70 xDrive leads by 0.99 s and sits roughly 9 m ahead.

From 100 km/h to 400 metres

At 200 metres, the i7 M70 xDrive is doing 155 km/h against 139 km/h for the S3 Sportback. The gap is 0.86 s. The challenger starts to claw back ground.

At 400 metres standing start, the i7 M70 xDrive crosses the line in 11.83 s versus 13.08 s. The 1.25 s gap represents roughly 60 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the i7 M70 xDrive continues to build its lead. At 600 metres, it runs at 214 km/h versus 197 km/h. At 1,000 metres, the i7 M70 xDrive finishes in 21.61 s versus 23.72 s, with a 2.11 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the i7 M70 xDrive and the S3 Sportback are governed to 250 (i.e. 155 mph - industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

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 7.65 seconds. The 0.99 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
