Cayenne (Tiptronic S) vs IS 300 AWD: chronicle of a drag race at 220 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 8.05 s for the Cayenne (Tiptronic S). Despite the faster sprint time, the Cayenne (Tiptronic S) is 9 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
From 100 km/h to 400 metres
At 200 metres, the Cayenne (Tiptronic S) is doing 117 km/h against 122 km/h for the IS 300 AWD. The gap is 0.19 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 15.79 s. The 0.13 s gap represents roughly 5 m of track — barely a car length.
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 163 km/h. At 1,000 metres, the IS 300 AWD finishes in 27.75 s versus 28.75 s, with a 1.00 s lead. Both vehicles have similar top speeds (220 vs 210 km/h), preventing any comeback.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Cayenne (Tiptronic S) is capped at 227 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.
With two combustion powertrains, the difference comes down to power-to-weight ratio (7.38 kg/hp vs 7.08 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.92 seconds. The 0.35 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Lexus IS 300 AWD is slightly faster than the Porsche Cayenne (Tiptronic S) to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
