The start: 0 to 100 km/h

Off the line, the S3 Sportback hits 100 km/h in 4.64 s versus 6.00 s for the Seal 313 2WD. Despite lacking instant torque, 333 hp of power compensates. At this point, the S3 Sportback leads by 1.36 s and sits roughly 19 m ahead.

From 100 km/h to 400 metres

At 200 metres, the S3 Sportback is doing 139 km/h against 135 km/h for the Seal 313 2WD. The gap is 0.91 s. The challenger starts to claw back ground.

At 400 metres standing start, the S3 Sportback crosses the line in 13.08 s versus 14.21 s. The 1.12 s gap represents roughly 51 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the S3 Sportback continues to build its lead. At 600 metres, it runs at 197 km/h versus 180 km/h. At 1,000 metres, the S3 Sportback finishes in 23.72 s versus 26.31 s, with a 2.59 s lead.

What the numbers don’t tell you

Both rivals are electronically governed, but not at the same level: the S3 Sportback is capped at 250 (i.e. 155 mph - industry threshold) km/h, the Seal 313 2WD at 180 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 8.80 seconds. The 1.36 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
