IS 300 RWD vs Countryman S ALL4: chronicle of a drag race at 236 km/h
The launch: 0 to 100 km/h
Off the line, the Countryman S ALL4 hits 100 km/h in 7.33 s versus 7.40 s for the IS 300 RWD. The 0.07 s gap is negligible: both vehicles are neck and neck.
From 100 km/h to 400 metres
At 200 metres, the Countryman S ALL4 is doing 120 km/h against 124 km/h for the IS 300 RWD. The gap is 0.30 s. The gap widens compared to the 0-100.
At 400 metres standing start, the Countryman S ALL4 crosses the line in 15.37 s versus 15.44 s. The 0.07 s gap represents roughly 3 m of track — barely a car length.
Beyond 400 metres: top speed comes into play
Past 400 metres, the situation changes. The IS 300 RWD maxes out at 225 km/h while the Countryman S ALL4 keeps accelerating towards 236 km/h. At 600 metres, the gap has dropped to 0.11 s.
Around 472 metres, both vehicles are level. This is the inversion point: the IS 300 RWD overcomes its launch deficit thanks to a 11 km/h higher top speed.
At 1,000 metres, the IS 300 RWD finishes in 27.59 s versus 27.99 s. The 0.40 s delta shows an extremely tight race.
What the numbers don’t tell you
On paper, the IS 300 RWD combines 245 hp, 350 Nm and 1,695 kg — a clear theoretical edge over the Countryman S ALL4. Yet the Countryman S ALL4 launches quicker. At standstill, both motors deliver peak torque from 0 rpm: the decisive factor is no longer raw power, but available grip. If the Countryman S ALL4 has a better traction coefficient (tyres, weight distribution, traction control calibration), it puts down more force despite inferior specs — exactly what the simulation reflects, calibrated on manufacturer 0-100 km/h times.
The Countryman S ALL4 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.
Electronically capped at 225 km/h, the IS 300 RWD never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor — it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (6.92 kg/hp vs 8.50 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.66 seconds. The 0.07 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Lexus IS 300 RWD and MINI Countryman S ALL4 are virtually tied to 100 km/h. The gap is under a tenth of a second — only the physics engine can settle it step by step.
