Off the line, the Bmw M340i xDrive hits 100 km/h in 4.46 s versus 5.76 s for the IS 350 F Sport RWD. At this point, the Bmw M340i xDrive leads by 1.30 s and sits roughly 16 m ahead.
At 200 metres, the Bmw M340i xDrive is doing 147 km/h against 137 km/h for the IS 350 F Sport RWD. The gap is 0.96 s. The challenger starts to claw back ground.
At 400 metres standing start, the Bmw M340i xDrive crosses the line in 12.56 s versus 13.83 s. The 1.27 s gap represents roughly 59 m of track — a gap visible to the naked eye.
Past 400 metres, the Bmw M340i xDrive continues to build its lead. At 600 metres, it runs at 207 km/h versus 193 km/h. At 1,000 metres, the Bmw M340i xDrive finishes in 22.70 s versus 24.69 s, with a 1.99 s lead. Both vehicles have similar top speeds (250 (i.e. 155 mph — industry threshold) vs 250 (i.e. 155 mph — industry threshold) km/h), preventing any comeback.
The Bmw M340i xDrive features all-wheel drive (AWD) against the IS 350 F Sport 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 share the same electronic speed cap: the Bmw M340i xDrive and the IS 350 F Sport RWD are governed to 250 (i.e. 155 mph — industry threshold) km/h. At that speed, standard-fit tyres approach their safety threshold — an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.
With two combustion powertrains, the difference comes down to power-to-weight ratio (4.47 kg/hp vs 5.58 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.49 seconds. The 1.30 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
