Mercedes E 400 e 4MATIC Saloon W214 vs Tesla Model S 85: which is truly faster?

Off the line, the E 400 e 4MATIC Saloon hits 100 km/h in 5.31 s versus 5.75 s for the Model S 85. At this point, the E 400 e 4MATIC Saloon leads by 0.44 s and sits roughly 13 m ahead.

At 200 metres, the E 400 e 4MATIC Saloon is doing 135 km/h against 137 km/h for the Model S 85. The gap is 0.42 s. The gap remains stable from the start.

At 400 metres standing start, the E 400 e 4MATIC Saloon crosses the line in 13.57 s versus 13.94 s. The 0.37 s gap represents roughly 17 m of track - two to three car lengths.

Past 400 metres, the E 400 e 4MATIC Saloon continues to build its lead. At 600 metres, it runs at 190 km/h versus 190 km/h. At 1,000 metres, the E 400 e 4MATIC Saloon finishes in 24.58 s versus 25.17 s, with a 0.59 s lead.

The E 400 e 4MATIC Saloon 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 E 400 e 4MATIC Saloon 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.

With two plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (5.89 kg/hp vs 5.82 kg/hp) and transmission (Unknown vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 8.41 seconds. The 0.44 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
