Off the line, the A4 40 TFSI hits 100 km/h in 7.28 s versus 7.70 s for the IS 300 AWD. At this point, the A4 40 TFSI leads by 0.42 s and sits roughly 15 m ahead.
At 200 metres, the A4 40 TFSI is doing 119 km/h against 122 km/h for the IS 300 AWD. The gap is 0.48 s. The gap remains stable from the start.
At 400 metres standing start, the A4 40 TFSI crosses the line in 15.36 s versus 15.66 s. The 0.30 s gap represents roughly 13 m of track - two to three car lengths.
Past 400 metres, the situation changes. The IS 300 AWD maxes out at 210 km/h while the A4 40 TFSI keeps accelerating towards 232 km/h. At 600 metres, the gap has dropped to 0.10 s.
Around 696 metres, both vehicles are level. This is the inversion point: the IS 300 AWD overcomes its launch deficit thanks to a 22 km/h higher top speed.
At 1,000 metres, the IS 300 AWD finishes in 27.75 s versus 28.08 s. The 0.33 s delta shows an extremely tight race.
Electronically capped at 210 km/h, the IS 300 AWD 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 (7.08 kg/hp vs 7.97 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.78 seconds. The 0.42 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, A4 40 TFSI wins (7,28 s vs 7,70 s).
IS 300 AWD goes from 0 to 100 km/h in 7,70 seconds (calibrated simulation).
