Bmw M240i Coupé vs IS 350 F Sport RWD: chronicle of a drag race at 250 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw M240i Coupé hits 100 km/h in 4.68 s versus 5.94 s for the IS 350 F Sport RWD. At this point, the Bmw M240i Coupé leads by 1.26 s and sits roughly 14 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw M240i Coupé is doing 149 km/h against 136 km/h for the IS 350 F Sport RWD. The gap is 0.94 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M240i Coupé crosses the line in 12.70 s versus 14.07 s. The 1.37 s gap represents roughly 62 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw M240i Coupé continues to build its lead. At 600 metres, it runs at 210 km/h versus 188 km/h. At 1,000 metres, the Bmw M240i Coupé finishes in 22.71 s versus 25.26 s, with a 2.54 s lead. Both vehicles have similar top speeds (250 vs 240 km/h), preventing any comeback.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the Bmw M240i Coupé is capped at 250 km/h, the IS 350 F Sport RWD at 240 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 (4.37 kg/hp vs 5.43 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.71 seconds. The 1.26 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw M240i Coupé has a clear edge over the Lexus IS 350 F Sport RWD to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
