Off the line, the S5 Avant hits 100 km/h in 4.53 s versus 5.81 s for the TT 45 TFSI. At this point, the S5 Avant leads by 1.28 s and sits roughly 16 m ahead.
At 200 metres, the S5 Avant is doing 142 km/h against 133 km/h for the TT 45 TFSI. The gap is 0.94 s. The challenger starts to claw back ground.
At 400 metres standing start, the S5 Avant crosses the line in 12.83 s versus 14.06 s. The 1.23 s gap represents roughly 55 m of track - a gap visible to the naked eye.
Past 400 metres, the S5 Avant continues to build its lead. At 600 metres, it runs at 197 km/h versus 184 km/h. At 1,000 metres, the S5 Avant finishes in 23.49 s versus 25.49 s, with a 2.00 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph - industry threshold) vs 251 (i.e. 155 mph - industry threshold) km/h), preventing any comeback.
The S5 Avant features all-wheel drive (AWD) against the TT 45 TFSI’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.
Electronically capped at 250 (i.e. 155 mph - industry threshold) km/h, the S5 Avant never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (5.35 kg/hp vs 5.43 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.89 seconds. The 1.28 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, S5 Avant wins (4,53 s vs 5,81 s).
