Manufacturer technical specifications. The power-to-weight ratio is the key physical factor in a drag race.

The start: 0 to 100 km/h

Off the line, the i3 hits 100 km/h in 7.24 s versus 7.54 s for the Leon e-Hybrid. At this point, the i3 leads by 0.30 s and sits roughly 9 m ahead.

From 100 km/h to 400 metres

At 200 metres, the i3 is doing 122 km/h against 125 km/h for the Leon e-Hybrid. The gap is 0.27 s. The gap remains stable from the start.

At 400 metres standing start, the i3 crosses the line in 15.40 s versus 15.48 s. The 0.08 s gap represents roughly 3 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the situation changes. The i3 maxes out at 150 km/h while the Leon e-Hybrid keeps accelerating towards 225 km/h. At 600 metres, the gap has dropped to 0.37 s.

Around 458 metres, both vehicles are level. This is the inversion point: the Leon e-Hybrid overcomes its launch deficit thanks to a 75 km/h higher top speed.

At 1,000 metres, the Leon e-Hybrid finishes in 27.56 s versus 29.80 s. The 2.24 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 i3 at 150 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 7.47 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 11.47 seconds. The 0.30 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
