The start: 0 to 100 km/h

Off the line, the Formentor VZ e-Hybrid hits 100 km/h in 6.54 s versus 8.51 s for the G9. At this point, the Formentor VZ e-Hybrid leads by 1.97 s and sits roughly 27 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Formentor VZ e-Hybrid is doing 127 km/h against 120 km/h for the G9. The gap is 1.35 s. The challenger starts to claw back ground.

At 400 metres standing start, the Formentor VZ e-Hybrid crosses the line in 14.71 s versus 16.32 s. The 1.61 s gap represents roughly 65 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Formentor VZ e-Hybrid continues to build its lead. At 600 metres, it runs at 175 km/h versus 169 km/h. At 1,000 metres, the Formentor VZ e-Hybrid finishes in 26.77 s versus 28.71 s, with a 1.94 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the G9 is capped at 200 km/h, the Formentor VZ e-Hybrid at 225 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 plug-in hybrid powertrains, the difference comes down to power-to-weight ratio (7.18 kg/hp vs 6.83 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 1.97 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
