The start: 0 to 100 km/h

Off the line, the 630d Gran Turismo hits 100 km/h in 6.06 s versus 7.45 s for the Leon VZe. Despite lacking instant torque, 265 hp of power compensates. At this point, the 630d Gran Turismo leads by 1.39 s and sits roughly 24 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 630d Gran Turismo is doing 127 km/h against 126 km/h for the Leon VZe. The gap is 1.03 s. The challenger starts to claw back ground.

At 400 metres standing start, the 630d Gran Turismo crosses the line in 14.32 s versus 15.41 s. The 1.09 s gap represents roughly 46 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 630d Gran Turismo continues to build its lead. At 600 metres, it runs at 177 km/h versus 174 km/h. At 1,000 metres, the 630d Gran Turismo finishes in 26.17 s versus 27.49 s, with a 1.32 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the 630d Gran Turismo is capped at 250 (i.e. 155 mph - industry threshold) 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 10.94 seconds. The 1.39 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
