Off the line, the 540i hits 100 km/h in 5.06 s versus 5.13 s for the S 450 d 4MATIC Saloon, long version. The 0.07 s gap is negligible: both vehicles are neck and neck.
At 200 metres, the S 450 d 4MATIC Saloon, long version is doing 135 km/h against 143 km/h for the 540i. The gap is 0.11 s. The gap remains stable from the start.
At 400 metres standing start, the 540i crosses the line in 13.21 s versus 13.33 s. The 0.12 s gap represents roughly 6 m of track - barely a car length.
Past 400 metres, the 540i continues to build its lead. At 600 metres, it runs at 200 km/h versus 194 km/h. At 1,000 metres, the 540i finishes in 23.70 s versus 24.11 s, with a 0.41 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 S 450 d 4MATIC Saloon, long version features all-wheel drive (AWD) against the 540i’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 S 450 d 4MATIC Saloon, long version and the 540i 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 (6.14 kg/hp vs 4.69 kg/hp) and transmission (Unknown vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.01 seconds. The 0.07 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, S 450 d 4MATIC Saloon, long version W223 and 540i G30 are neck and neck (5,06 s vs 5,13 s, no significant gap).
S 450 d 4MATIC Saloon, long version W223 goes from 0 to 100 km/h in 5,13 seconds (calibrated simulation).
S 450 d 4MATIC Saloon, long version W223: 367 hp, ratio 6,14 kg/hp. 540i G30: 340 hp, ratio 4,69 kg/hp.
S 450 d 4MATIC Saloon, long version W223: 250 km/h. 540i G30: 250 km/h.
