IS 300 RWD 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 RWD hits 100 km/h in 7.40 s versus 8.16 s for the A6 Sedan. At this point, the IS 300 RWD leads by 0.76 s and sits roughly 6 m ahead.
From 100 km/h to 400 metres
At 200 metres, the IS 300 RWD is doing 124 km/h against 119 km/h for the A6 Sedan. The gap is 0.37 s. The challenger starts to claw back ground.
At 400 metres standing start, the IS 300 RWD crosses the line in 15.44 s versus 16.06 s. The 0.62 s gap represents roughly 25 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the IS 300 RWD 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 RWD finishes in 27.59 s versus 28.62 s, with a 1.03 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
Both rivals are electronically governed, but not at the same level: the IS 300 RWD is capped at 225 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 (6.92 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 0.76 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Lexus IS 300 RWD 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.
