Bmw 330d xDrive vs IS 300 RWD: chronicle of a drag race at 250 km/h
The launch: 0 to 100 km/h
Off the line, the Bmw 330d xDrive hits 100 km/h in 4.95 s versus 7.40 s for the IS 300 RWD. At this point, the Bmw 330d xDrive leads by 2.45 s and sits roughly 32 m ahead.
From 100 km/h to 400 metres
At 200 metres, the Bmw 330d xDrive is doing 135 km/h against 124 km/h for the IS 300 RWD. The gap is 1.77 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw 330d xDrive crosses the line in 13.28 s versus 15.44 s. The 2.16 s gap represents roughly 90 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the Bmw 330d xDrive continues to build its lead. At 600 metres, it runs at 189 km/h versus 173 km/h. At 1,000 metres, the Bmw 330d xDrive finishes in 24.36 s versus 27.59 s, with a 3.23 s lead.
What the numbers don’t tell you
The Bmw 330d xDrive features all-wheel drive (AWD) against the IS 300 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 Bmw 330d xDrive is capped at 250 km/h, the IS 300 RWD at 225 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 (6.17 kg/hp vs 6.92 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.11 seconds. The 2.45 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Bmw 330d xDrive has a clear edge over the Lexus IS 300 RWD to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
