The start: 0 to 100 km/h

Off the line, the I-PACE EV400 hits 100 km/h in 4.84 s versus 6.73 s for the 4 Long Range RWD. At this point, the I-PACE EV400 leads by 1.90 s and sits roughly 21 m ahead.

From 100 km/h to 400 metres

At 200 metres, the I-PACE EV400 is doing 141 km/h against 129 km/h for the 4 Long Range RWD. The gap is 1.32 s. The challenger starts to claw back ground.

At 400 metres standing start, the I-PACE EV400 crosses the line in 13.18 s versus 14.92 s. The 1.73 s gap represents roughly 74 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the I-PACE EV400 continues to build its lead. At 600 metres, it runs at 192 km/h versus 176 km/h. At 1,000 metres, the I-PACE EV400 finishes in 24.36 s versus 27.23 s, with a 2.88 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the I-PACE EV400 is capped at 200 km/h, the 4 Long Range RWD at 180 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 (5.52 kg/hp vs 7.00 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 10.07 seconds. The 1.90 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
