IS 300 AWD vs A6 Sedan: chronicle of a drag race at 244 km/h
The launch: 0 to 100 km/h
Off the line, the IS 300 AWD hits 100 km/h in 7.70 s versus 8.16 s for the A6 Sedan. At this point, the IS 300 AWD leads by 0.46 s and sits roughly 3 m ahead.
From 100 km/h to 400 metres
At 200 metres, the IS 300 AWD is doing 122 km/h against 119 km/h for the A6 Sedan. The gap is 0.21 s. The challenger starts to claw back ground.
At 400 metres standing start, the IS 300 AWD crosses the line in 15.66 s versus 16.06 s. The 0.40 s gap represents roughly 16 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the IS 300 AWD continues to build its lead. At 600 metres, it runs at 173 km/h versus 167 km/h. At 1,000 metres, the IS 300 AWD finishes in 27.75 s versus 28.62 s, with a 0.87 s lead. Despite a higher top speed (244 km/h), the A6 Sedan never recovers its launch deficit.
What the numbers don’t tell you
The IS 300 AWD features all-wheel drive (AWD) against the A6 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 IS 300 AWD is capped at 210 km/h, the A6 Sedan at 244 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 (7.08 kg/hp vs 8.68 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.53 seconds. The 0.46 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Lexus IS 300 AWD has a clear edge over the Audi A6 Sedan to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
