Cayenne Turbo S vs IS 500 F Sport RWD: chronicle of a drag race at 279 km/h
The launch: 0 to 100 km/h
Off the line, the Cayenne Turbo S hits 100 km/h in 4.36 s versus 4.54 s for the IS 500 F Sport RWD. At this point, the Cayenne Turbo S leads by 0.18 s and sits roughly 2 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Cayenne Turbo S is doing 152 km/h against 154 km/h for the IS 500 F Sport RWD. The gap is 0.07 s. The challenger starts to claw back ground.
At 400 metres standing start, the Cayenne Turbo S crosses the line in 12.42 s versus 12.42 s. The 0.00 s gap represents roughly 0 m of track
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The IS 500 F Sport RWD maxes out at 270 km/h while the Cayenne Turbo S keeps accelerating towards 279 km/h. At 600 metres, the gap has dropped to 0.07 s.
Around 412 metres, both vehicles are level. This is the inversion point: the IS 500 F Sport RWD overcomes its launch deficit thanks to a 9 km/h higher top speed.
At 1,000 metres, the IS 500 F Sport RWD finishes in 22.06 s versus 22.41 s. The 0.35 s delta shows an extremely tight race.
What the numbers don’t tell you
The Cayenne Turbo S features all-wheel drive (AWD) against the IS 500 F Sport RWD’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Both rivals are electronically governed, but not at the same level: the Cayenne Turbo S is capped at 282 km/h, the IS 500 F Sport RWD at 270 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 (3.81 kg/hp vs 3.67 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.36 seconds. The 0.18 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Cayenne Turbo S and Lexus IS 500 F Sport RWD are virtually tied to 100 km/h. The gap is under a tenth of a second — only the physics engine can settle it step by step.
