The start: 0 to 100 km/h

Off the line, the 320e hits 100 km/h in 7.46 s versus 7.54 s for the Leon e-Hybrid. The 0.08 s gap is negligible: both vehicles are neck and neck.

From 100 km/h to 400 metres

At 200 metres, the 320e is doing 115 km/h against 125 km/h for the Leon e-Hybrid. The gap is 0.54 s. The gap widens compared to the 0-100.

At 400 metres standing start, the 320e crosses the line in 15.43 s versus 15.48 s. The 0.05 s gap represents roughly 2 m of track

Beyond 400 metres: top speed comes into play

Past 400 metres, the situation changes. The 320e maxes out at 215 km/h while the Leon e-Hybrid keeps accelerating towards 225 km/h. At 600 metres, the gap has dropped to 0.40 s.

Around 420 metres, both vehicles are level. This is the inversion point: the Leon e-Hybrid overcomes its launch deficit thanks to a 10 km/h higher top speed.

At 1,000 metres, the Leon e-Hybrid finishes in 27.56 s versus 28.77 s. The 1.21 s delta in favour of the Leon e-Hybrid shows that top speed makes a clear difference.

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 320e at 220 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 (6.76 kg/hp vs 8.65 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 12.74 seconds. The 0.08 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
