The start: 0 to 100 km/h

Off the line, the CLA 220 Limousine hits 100 km/h in 7.31 s versus 7.54 s for the Leon e-Hybrid. Despite lacking instant torque, 211 hp of power compensates. At this point, the CLA 220 Limousine leads by 0.23 s and sits roughly 10 m ahead.

From 100 km/h to 400 metres

At 200 metres, the CLA 220 Limousine is doing 122 km/h against 125 km/h for the Leon e-Hybrid. The gap is 0.31 s. The gap remains stable from the start.

At 400 metres standing start, the CLA 220 Limousine crosses the line in 15.32 s versus 15.48 s. The 0.16 s gap represents roughly 7 m of track - barely a car length.

Beyond 400 metres: top speed comes into play

Past 400 metres, the gap narrows. The Leon e-Hybrid maxes out at 225 km/h while the CLA 220 Limousine keeps accelerating towards 240 km/h. At 600 metres, the gap is down to 0.07 s from 0.16 s at 400 metres.

At 1,000 metres, the CLA 220 Limousine finishes in 27.53 s versus 27.56 s, with just 0.02 s to spare. The Leon e-Hybrid fails to fully close the launch gap.

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 CLA 220 Limousine at 240 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 11.41 seconds. The 0.23 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
