Cupra Born VZ vs Mercedes A 250 W177: which is truly faster?

Off the line, the Born VZ hits 100 km/h in 5.73 s versus 6.26 s for the A 250. The instant torque of 310 Nm from the electric motor makes the difference. At this point, the Born VZ leads by 0.53 s and sits roughly 6 m ahead.

At 200 metres, the Born VZ is doing 138 km/h against 134 km/h for the A 250. The gap is 0.37 s. The challenger starts to claw back ground.

At 400 metres standing start, the Born VZ crosses the line in 13.96 s versus 14.39 s. The 0.43 s gap represents roughly 20 m of track - two to three car lengths.

Past 400 metres, the situation changes. The Born VZ maxes out at 160 km/h while the A 250 keeps accelerating towards 250 (i.e. 155 mph - industry threshold) km/h. At 600 metres, the gap has dropped to 0.02 s.

Around 593 metres, both vehicles are level. This is the inversion point: the A 250 overcomes its launch deficit thanks to a 90 km/h higher top speed.

At 1,000 metres, the A 250 finishes in 25.56 s versus 27.45 s. The 1.89 s delta in favour of the A 250 shows that top speed makes a clear difference.

Both rivals are electronically governed, but not at the same level: the Born VZ is capped at 160 km/h, the A 250 at 250 (i.e. 155 mph - industry threshold) 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 9.15 seconds. The 0.53 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
