IS 350 F Sport RWD vs Boxster: chronicle of a drag race at 261 km/h
The launch: 0 to 100 km/h
Off the line, the Boxster hits 100 km/h in 5.71 s versus 5.94 s for the IS 350 F Sport RWD. At this point, the Boxster leads by 0.23 s and sits roughly 7 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Boxster is doing 134 km/h against 136 km/h for the IS 350 F Sport RWD. The gap is 0.22 s. The gap remains stable from the start.
At 400 metres standing start, the Boxster crosses the line in 13.88 s versus 14.07 s. The 0.19 s gap represents roughly 9 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Boxster continues to build its lead. At 600 metres, it runs at 189 km/h versus 188 km/h. At 1,000 metres, the Boxster finishes in 25.03 s versus 25.26 s, with a 0.23 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the IS 350 F Sport RWD is capped at 240 km/h, the Boxster at 261 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 (5.43 kg/hp vs 5.27 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.71 seconds. The 0.23 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche Boxster is slightly faster than the Lexus IS 350 F Sport RWD to 100 km/h. The edge holds on standing starts but may narrow at higher speeds depending on aerodynamic load.
