The start: 0 to 100 km/h

Off the line, the 120d hits 100 km/h in 7.24 s versus 7.54 s for the Leon e-Hybrid. Despite lacking instant torque, 190 hp of power compensates. At this point, the 120d leads by 0.30 s and sits roughly 7 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 120d is doing 123 km/h against 125 km/h for the Leon e-Hybrid. The gap is 0.23 s. The gap remains stable from the start.

At 400 metres standing start, the 120d crosses the line in 15.38 s versus 15.48 s. The 0.10 s gap represents roughly 4 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the situation changes. The Leon e-Hybrid maxes out at 225 km/h while the 120d keeps accelerating towards 231 km/h. At 600 metres, the gap has dropped to 0.01 s.

Around 583 metres, both vehicles are level. This is the inversion point: the Leon e-Hybrid overcomes its launch deficit thanks to a 6 km/h higher top speed.

At 1,000 metres, the Leon e-Hybrid finishes in 27.56 s versus 27.74 s. The 0.19 s delta shows an extremely tight race.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the Leon e-Hybrid is capped at 225 km/h, the 120d at 231 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 11.29 seconds. The 0.30 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
