Tesla Model S P85D vs Mercedes CLA 200 Limousine: which is truly faster?

Off the line, the Model S P85D hits 100 km/h in 3.33 s versus 8.09 s for the CLA 200 Limousine. The instant torque of 931 Nm from the electric motor makes the difference. At this point, the Model S P85D leads by 4.76 s and sits roughly 22 m ahead.

At 200 metres, the Model S P85D is doing 167 km/h against 116 km/h for the CLA 200 Limousine. The gap is 3.11 s. The challenger starts to claw back ground.

At 400 metres standing start, the Model S P85D crosses the line in 11.17 s versus 15.93 s. The 4.75 s gap represents roughly 176 m of track - a gap visible to the naked eye.

Past 400 metres, the Model S P85D continues to build its lead. At 600 metres, it runs at 232 km/h versus 164 km/h. At 1,000 metres, the Model S P85D finishes in 20.31 s versus 28.73 s, with a 8.42 s lead.

The Model S P85D features all-wheel drive (AWD) against the CLA 200 Limousine’s FWD. 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 S P85D is capped at 249 (i.e. 155 mph - industry threshold) km/h, the CLA 200 Limousine at 232 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 12.89 seconds. The 4.76 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
