Off the line, the i7 xDrive60 hits 100 km/h in 4.66 s versus 4.84 s for the S4 TDI. The instant torque of 745 Nm from the electric motor makes the difference. Despite the faster sprint time, the S4 TDI is 1 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the i7 xDrive60 is doing 145 km/h against 140 km/h for the S4 TDI. The gap is 0.10 s. The gap remains stable from the start.
At 400 metres standing start, the i7 xDrive60 crosses the line in 12.86 s versus 13.12 s. The 0.26 s gap represents roughly 13 m of track - two to three car lengths.
Past 400 metres, the i7 xDrive60 continues to build its lead. At 600 metres, it runs at 203 km/h versus 195 km/h. At 1,000 metres, the i7 xDrive60 finishes in 23.17 s versus 23.86 s, with a 0.69 s lead. Both vehicles have similar top speeds (240 vs 250 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
The S4 TDI features all-wheel drive (AWD) against the i7 xDrive60’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Both rivals are electronically governed, but not at the same level: the i7 xDrive60 is capped at 240 km/h, the S4 TDI at 250 (i.e. 155 mph - industry threshold) 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 7.47 seconds. The 0.18 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, i7 xDrive60 G70 wins (4,66 s vs 4,83 s).
