911 Carrera 4 Cabriolet vs Seal 313 2WD: chronicle of a drag race at 283 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Carrera 4 Cabriolet hits 100 km/h in 4.37 s versus 6.00 s for the Seal 313 2WD. Despite lacking instant torque, 375 hp of power compensates. At this point, the 911 Carrera 4 Cabriolet leads by 1.63 s and sits roughly 18 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Carrera 4 Cabriolet is doing 152 km/h against 135 km/h for the Seal 313 2WD. The gap is 1.24 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Carrera 4 Cabriolet crosses the line in 12.42 s versus 14.21 s. The 1.79 s gap represents roughly 80 m of track — a gap visible to the naked eye.
Beyond 400 metres: top speed comes into play
Past 400 metres, the 911 Carrera 4 Cabriolet continues to build its lead. At 600 metres, it runs at 212 km/h versus 180 km/h. At 1,000 metres, the 911 Carrera 4 Cabriolet finishes in 22.38 s versus 26.31 s, with a 3.93 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the 911 Carrera 4 Cabriolet is capped at 288 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 1.63 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 Carrera 4 Cabriolet has a clear edge over the BYD Seal 313 2WD to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
