The start: 0 to 100 km/h

Off the line, the A6 Sedan TFSI quattro S tronic 270 kW hits 100 km/h in 4.65 s versus 9.87 s for the A3 Sedan. At this point, the A6 Sedan TFSI quattro S tronic 270 kW leads by 5.23 s and sits roughly 32 m ahead.

From 100 km/h to 400 metres

At 200 metres, the A6 Sedan TFSI quattro S tronic 270 kW is doing 141 km/h against 108 km/h for the A3 Sedan. The gap is 2.87 s. The challenger starts to claw back ground.

At 400 metres standing start, the A6 Sedan TFSI quattro S tronic 270 kW crosses the line in 12.93 s versus 17.21 s. The 4.28 s gap represents roughly 149 m of track — a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the A6 Sedan TFSI quattro S tronic 270 kW continues to build its lead. At 600 metres, it runs at 198 km/h versus 150 km/h. At 1,000 metres, the A6 Sedan TFSI quattro S tronic 270 kW finishes in 23.55 s versus 31.24 s, with a 7.69 s lead.

What the numbers don’t tell you

The A6 Sedan TFSI quattro S tronic 270 kW features all-wheel drive (AWD) against the A3 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.

Electronically capped at 250 (i.e. 155 mph — industry threshold) km/h, the A6 Sedan TFSI quattro S tronic 270 kW 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 (5.40 kg/hp vs 11.68 kg/hp) and transmission (Automatic vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 16.25 seconds. The 5.23 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
