Audi e-tron GT quattro vs Lexus IS 300 AWD: which is truly faster?

Off the line, the e-tron GT quattro hits 100 km/h in 4.14 s versus 7.70 s for the IS 300 AWD. The instant torque of 830 Nm from the electric motor makes the difference. At this point, the e-tron GT quattro leads by 3.56 s and sits roughly 28 m ahead.

At 200 metres, the e-tron GT quattro is doing 149 km/h against 122 km/h for the IS 300 AWD. The gap is 2.42 s. The challenger starts to claw back ground.

At 400 metres standing start, the e-tron GT quattro crosses the line in 12.36 s versus 15.66 s. The 3.30 s gap represents roughly 133 m of track - a gap visible to the naked eye.

Past 400 metres, the e-tron GT quattro continues to build its lead. At 600 metres, it runs at 208 km/h versus 173 km/h. At 1,000 metres, the e-tron GT quattro finishes in 22.46 s versus 27.75 s, with a 5.29 s lead.

Both rivals are electronically governed, but not at the same level: the e-tron GT quattro is capped at 245 km/h, the IS 300 AWD at 210 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.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.57 seconds. The 3.56 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
