Off the line, the IS 300 AWD hits 100 km/h in 7.70 s versus 7.72 s for the A5 Avant. The 0.02 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the A5 Avant is doing 122 km/h against 122 km/h for the IS 300 AWD. The gap is 0.00 s. The gap remains stable from the start.
At 400 metres standing start, the IS 300 AWD crosses the line in 15.66 s versus 15.70 s. The 0.05 s gap represents roughly 2 m of track
Past 400 metres, the IS 300 AWD continues to build its lead. At 600 metres, it runs at 173 km/h versus 172 km/h. At 1,000 metres, the IS 300 AWD finishes in 27.75 s versus 27.94 s, with a 0.19 s lead. Despite a higher top speed (245 km/h), the A5 Avant never recovers its launch deficit.
Both rivals are electronically governed, but not at the same level: the IS 300 AWD is capped at 210 km/h, the A5 Avant at 245 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 8.38 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.72 seconds. The 0.02 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, IS 300 AWD and A5 Avant are neck and neck (7,70 s vs 7,72 s, no significant gap).
IS 300 AWD goes from 0 to 100 km/h in 7,70 seconds (calibrated simulation).
IS 300 AWD: 245 hp, ratio 7,08 kg/hp. A5 Avant: 204 hp, ratio 8,38 kg/hp.
IS 300 AWD: 210 km/h. A5 Avant: 245 km/h.
