Off the line, the Model S 85 hits 100 km/h in 5.75 s versus 6.04 s for the iX xDrive40. Despite the faster sprint time, the iX xDrive40 is 6 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the Model S 85 is doing 137 km/h against 127 km/h for the iX xDrive40. The gap is 0.04 s. The challenger starts to claw back ground.
At 400 metres standing start, the Model S 85 crosses the line in 13.94 s versus 14.36 s. The 0.43 s gap represents roughly 18 m of track - two to three car lengths.
Past 400 metres, the Model S 85 continues to build its lead. At 600 metres, it runs at 190 km/h versus 175 km/h. At 1,000 metres, the Model S 85 finishes in 25.17 s versus 26.37 s, with a 1.20 s lead. Both vehicles have similar top speeds (201 vs 200 km/h), preventing any comeback.
The iX xDrive40 features all-wheel drive (AWD) against the Model S 85’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 Model S 85 and the iX xDrive40 are governed to 201 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 electric powertrains, the difference comes down to power-to-weight ratio (5.82 kg/hp vs 7.48 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.74 seconds. The 0.29 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, Model S 85 wins (5,75 s vs 6,04 s).
Model S 85 goes from 0 to 100 km/h in 5,75 seconds (calibrated simulation).
