The start: 0 to 100 km/h

Off the line, the Leon VZe hits 100 km/h in 7.45 s versus 8.32 s for the V 300 d 4MATIC (long). The instant torque of 350 Nm from the electric motor makes the difference. Despite the faster sprint time, the V 300 d 4MATIC (long) is 8 m further along the track at this moment: stronger low-speed acceleration offsets a slower run beyond 100 km/h.

From 100 km/h to 400 metres

At 200 metres, the V 300 d 4MATIC (long) is doing 114 km/h against 126 km/h for the Leon VZe. The gap is 0.01 s. The challenger starts to claw back ground.

At 400 metres standing start, the Leon VZe crosses the line in 15.41 s versus 16.03 s. The 0.61 s gap represents roughly 23 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Leon VZe continues to build its lead. At 600 metres, it runs at 174 km/h versus 156 km/h. At 1,000 metres, the Leon VZe finishes in 27.49 s versus 29.55 s, with a 2.07 s lead.

What the numbers don’t tell you

The V 300 d 4MATIC (long) features all-wheel drive (AWD) against the Leon VZe’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 V 300 d 4MATIC (long) is capped at 217 km/h, the Leon VZe 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.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 14.08 seconds. The 0.87 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
