IS 500 F Sport RWD vs 718 Cayman GT4: chronicle of a drag race at 303 km/h
The launch: 0 to 100 km/h
Off the line, the 718 Cayman GT4 hits 100 km/h in 4.24 s versus 4.54 s for the IS 500 F Sport RWD. At this point, the 718 Cayman GT4 leads by 0.30 s and sits roughly 7 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 718 Cayman GT4 is doing 156 km/h against 154 km/h for the IS 500 F Sport RWD. The gap is 0.32 s. The gap remains stable from the start.
At 400 metres standing start, the 718 Cayman GT4 crosses the line in 12.02 s versus 12.42 s. The 0.41 s gap represents roughly 21 m of track — two to three car lengths.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 718 Cayman GT4 continues to build its lead. At 600 metres, it runs at 224 km/h versus 217 km/h. At 1,000 metres, the 718 Cayman GT4 finishes in 21.46 s versus 22.06 s, with a 0.60 s lead.
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 718 Cayman GT4 at 303 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 3.45 kg/hp) and transmission (Automatic vs Manual).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.32 seconds. The 0.30 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 718 Cayman GT4 is slightly faster than the Lexus IS 500 F Sport RWD to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
