Off the line, the P7i hits 100 km/h in 6.31 s versus 6.83 s for the CLA 250+ mit EQ Technologie. At this point, the P7i leads by 0.52 s and sits roughly 10 m ahead.
At 200 metres, the P7i is doing 129 km/h against 128 km/h for the CLA 250+ mit EQ Technologie. The gap is 0.41 s. The challenger starts to claw back ground.
At 400 metres standing start, the P7i crosses the line in 14.56 s versus 15.00 s. The 0.44 s gap represents roughly 19 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 176 km/h. At 1,000 metres, the P7i finishes in 26.38 s versus 26.90 s, with a 0.52 s lead. Both vehicles have similar top speeds (200 vs 210 km/h), preventing any comeback.
Both rivals are electronically governed, but not at the same level: the P7i is capped at 200 km/h, the CLA 250+ mit EQ Technologie at 210 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 electric powertrains, the difference comes down to power-to-weight ratio (7.18 kg/hp vs 7.56 kg/hp) and transmission (Automatic vs Unknown).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.25 seconds. The 0.52 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
