The start: 0 to 100 km/h

Off the line, the I-PACE EV400 hits 100 km/h in 4.84 s versus 8.51 s for the G9. At this point, the I-PACE EV400 leads by 3.68 s and sits roughly 31 m ahead.

From 100 km/h to 400 metres

At 200 metres, the I-PACE EV400 is doing 141 km/h against 120 km/h for the G9. The gap is 2.40 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 16.32 s. The 3.14 s gap represents roughly 124 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 169 km/h. At 1,000 metres, the I-PACE EV400 finishes in 24.36 s versus 28.71 s, with a 4.35 s lead. Both vehicles have similar top speeds (200 vs 200 km/h), preventing any comeback.

What the numbers don’t tell you

Both rivals share the same electronic speed cap: the I-PACE EV400 and the G9 are governed to 200 km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

With two electric powertrains, the difference comes down to power-to-weight ratio (5.52 kg/hp vs 7.18 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.63 seconds. The 3.68 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
