The start: 0 to 100 km/h

Off the line, the 120i hits 100 km/h in 6.91 s versus 7.54 s for the Leon e-Hybrid. Despite lacking instant torque, 178 hp of power compensates. At this point, the 120i leads by 0.63 s and sits roughly 14 m ahead.

From 100 km/h to 400 metres

At 200 metres, the 120i is doing 124 km/h against 125 km/h for the Leon e-Hybrid. The gap is 0.51 s. The challenger starts to claw back ground.

At 400 metres standing start, the 120i crosses the line in 15.02 s versus 15.48 s. The 0.46 s gap represents roughly 20 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the 120i continues to build its lead. At 600 metres, it runs at 174 km/h versus 174 km/h. At 1,000 metres, the 120i finishes in 27.09 s versus 27.56 s, with a 0.47 s lead. Both vehicles have similar top speeds (225 vs 235 km/h), preventing any comeback.

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 120i at 235 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 11.03 seconds. The 0.63 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
