Off the line, the P7i hits 100 km/h in 6.31 s versus 7.01 s for the CLA 220 4MATIC Saloon. The instant torque of 430 Nm from the electric motor makes the difference. Despite the faster sprint time, the CLA 220 4MATIC Saloon is 2 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.
At 200 metres, the P7i is doing 129 km/h against 120 km/h for the CLA 220 4MATIC Saloon. The gap is 0.16 s. The challenger starts to claw back ground.
At 400 metres standing start, the P7i crosses the line in 14.56 s versus 15.05 s. The 0.49 s gap represents roughly 20 m of track - two to three car lengths.
Past 400 metres, the P7i continues to build its lead. At 600 metres, it runs at 178 km/h versus 168 km/h. At 1,000 metres, the P7i finishes in 26.38 s versus 27.48 s, with a 1.11 s lead. Despite a higher top speed (237 km/h), the CLA 220 4MATIC Saloon never recovers its launch deficit.
The CLA 220 4MATIC Saloon features all-wheel drive (AWD) against the P7i’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 P7i is capped at 200 km/h, the CLA 220 4MATIC Saloon at 237 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 11.40 seconds. The 0.70 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, P7i wins (6,31 s vs 7,01 s).
