The start: 0 to 100 km/h

Off the line, the iX xDrive40 hits 100 km/h in 6.04 s versus 6.54 s for the Formentor VZ e-Hybrid. At this point, the iX xDrive40 leads by 0.50 s and sits roughly 9 m ahead.

From 100 km/h to 400 metres

At 200 metres, the iX xDrive40 is doing 127 km/h against 127 km/h for the Formentor VZ e-Hybrid. The gap is 0.35 s. The challenger starts to claw back ground.

At 400 metres standing start, the iX xDrive40 crosses the line in 14.36 s versus 14.71 s. The 0.34 s gap represents roughly 15 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the iX xDrive40 continues to build its lead. At 600 metres, it runs at 175 km/h versus 175 km/h. At 1,000 metres, the iX xDrive40 finishes in 26.37 s versus 26.77 s, with a 0.40 s lead. Despite a higher top speed (225 km/h), the Formentor VZ e-Hybrid never recovers its launch deficit.

What the numbers don’t tell you

The iX xDrive40 features all-wheel drive (AWD) against the Formentor VZ e-Hybrid’s FWD. 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 iX xDrive40 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 (7.48 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 10.06 seconds. The 0.50 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
