Off the line, the S3 Sportback hits 100 km/h in 4.64 s versus 7.79 s for the A5 Sedan. At this point, the S3 Sportback leads by 3.15 s and sits roughly 22 m ahead.
At 200 metres, the S3 Sportback is doing 139 km/h against 117 km/h for the A5 Sedan. The gap is 1.75 s. The challenger starts to claw back ground.
At 400 metres standing start, the S3 Sportback crosses the line in 13.08 s versus 15.74 s. The 2.65 s gap represents roughly 102 m of track - a gap visible to the naked eye.
Past 400 metres, the S3 Sportback continues to build its lead. At 600 metres, it runs at 197 km/h versus 162 km/h. At 1,000 metres, the S3 Sportback finishes in 23.72 s versus 28.62 s, with a 4.91 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 242 km/h), preventing any comeback.
The S3 Sportback features all-wheel drive (AWD) against the A5 Sedan’s FWD. 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 S3 Sportback is capped at 250 (i.e. 155 mph - industry threshold) km/h, the A5 Sedan at 242 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.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.61 kg/hp vs 8.92 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.41 seconds. The 3.15 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, S3 Sportback wins (4,64 s vs 7,79 s).
