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 7.54 s for the A5 Avant TFSI quattro S tronic 150 kW. At this point, the A6 Sedan TFSI quattro S tronic 270 kW leads by 2.90 s and sits roughly 16 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 116 km/h for the A5 Avant TFSI quattro S tronic 150 kW. The gap is 1.56 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 15.50 s. The 2.57 s gap represents roughly 98 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 161 km/h. At 1,000 metres, the A6 Sedan TFSI quattro S tronic 270 kW finishes in 23.55 s versus 28.53 s, with a 4.98 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph — industry threshold) vs 237 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the A6 Sedan TFSI quattro S tronic 270 kW is capped at 250 (i.e. 155 mph — industry threshold) km/h, the A5 Avant TFSI quattro S tronic 150 kW 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 (5.40 kg/hp vs 8.65 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.55 seconds. The 2.90 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
