Tesla Model X Performance vs Mercedes C 300 de Estate W206: which is truly faster?

Off the line, the Model X Performance hits 100 km/h in 3.05 s versus 6.17 s for the C 300 de Estate. At this point, the Model X Performance leads by 3.12 s and sits roughly 12 m ahead.

At 200 metres, the Model X Performance is doing 168 km/h against 123 km/h for the C 300 de Estate. The gap is 2.14 s. The challenger starts to claw back ground.

At 400 metres standing start, the Model X Performance crosses the line in 10.92 s versus 14.36 s. The 3.44 s gap represents roughly 140 m of track - a gap visible to the naked eye.

Past 400 metres, the Model X Performance continues to build its lead. At 600 metres, it runs at 233 km/h versus 179 km/h. At 1,000 metres, the Model X Performance finishes in 19.92 s versus 26.07 s, with a 6.15 s lead.

The Model X Performance features all-wheel drive (AWD) against the C 300 de Estate’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 Model X Performance is capped at 262 km/h, the C 300 de Estate at 240 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 (3.16 kg/hp vs 6.98 kg/hp) and transmission (Automatic vs Unknown).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.22 seconds. The 3.12 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
