Mercedes S 450 4MATIC Limousine Langversion W223 vs Tesla Model S 85: which is truly faster?

Off the line, the S 450 4MATIC Limousine Langversion hits 100 km/h in 4.86 s versus 5.75 s for the Model S 85. Despite lacking instant torque, 381 hp of power compensates. At this point, the S 450 4MATIC Limousine Langversion leads by 0.88 s and sits roughly 19 m ahead.

At 200 metres, the S 450 4MATIC Limousine Langversion is doing 138 km/h against 137 km/h for the Model S 85. The gap is 0.78 s. The challenger starts to claw back ground.

At 400 metres standing start, the S 450 4MATIC Limousine Langversion crosses the line in 13.08 s versus 13.94 s. The 0.86 s gap represents roughly 40 m of track - a gap visible to the naked eye.

Past 400 metres, the S 450 4MATIC Limousine Langversion continues to build its lead. At 600 metres, it runs at 196 km/h versus 190 km/h. At 1,000 metres, the S 450 4MATIC Limousine Langversion finishes in 23.76 s versus 25.17 s, with a 1.41 s lead.

The S 450 4MATIC Limousine Langversion 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 are electronically governed, but not at the same level: the S 450 4MATIC Limousine Langversion is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Model S 85 at 201 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.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.41 seconds. The 0.88 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
