Off the line, the S5 Sedan hits 100 km/h in 4.50 s versus 4.66 s for the i7 xDrive60. Despite lacking instant torque, 367 hp of power compensates. At this point, the S5 Sedan leads by 0.16 s and sits roughly 6 m ahead.
At 200 metres, the S5 Sedan is doing 142 km/h against 145 km/h for the i7 xDrive60. The gap is 0.15 s. The gap remains stable from the start.
At 400 metres standing start, the S5 Sedan crosses the line in 12.80 s versus 12.86 s. The 0.06 s gap represents roughly 3 m of track - barely a car length.
Past 400 metres, the situation changes. The i7 xDrive60 maxes out at 240 km/h while the S5 Sedan keeps accelerating towards 250 (i.e. 155 mph - industry threshold) km/h. At 600 metres, the gap has dropped to 0.03 s.
Around 539 metres, both vehicles are level. This is the inversion point: the i7 xDrive60 overcomes its launch deficit thanks to a 10 km/h higher top speed.
At 1,000 metres, the i7 xDrive60 finishes in 23.17 s versus 23.38 s. The 0.21 s delta shows an extremely tight race.
The S5 Sedan 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 S5 Sedan 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 7.04 seconds. The 0.16 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, S5 Sedan wins (4,50 s vs 4,66 s).
i7 xDrive60 G70 goes from 0 to 100 km/h in 4,66 seconds (calibrated simulation).
