IS 500 F Sport RWD vs Panamera S: chronicle of a drag race at 277 km/h
The launch: 0 to 100 km/h
Off the line, the IS 500 F Sport RWD hits 100 km/h in 4.54 s versus 5.16 s for the Panamera S. At this point, the IS 500 F Sport RWD leads by 0.62 s and sits roughly 6 m ahead.
From 100 km/h to 400 metres
At 200 metres, the IS 500 F Sport RWD is doing 154 km/h against 140 km/h for the Panamera S. The gap is 0.51 s. The challenger starts to claw back ground.
At 400 metres standing start, the IS 500 F Sport RWD crosses the line in 12.42 s versus 13.31 s. The 0.89 s gap represents roughly 43 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the IS 500 F Sport RWD continues to build its lead. At 600 metres, it runs at 217 km/h versus 197 km/h. At 1,000 metres, the IS 500 F Sport RWD finishes in 22.06 s versus 23.98 s, with a 1.92 s lead. Both vehicles have similar top speeds (270 vs 277 km/h), preventing any comeback.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the IS 500 F Sport RWD is capped at 270 km/h, the Panamera S at 283 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 (3.67 kg/hp vs 4.43 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.71 seconds. The 0.62 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Lexus IS 500 F Sport RWD has a clear edge over the Porsche Panamera S to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
