911 Carrera 4 GTS Cabriolet vs EX40 Twin Motor AWD: chronicle of a drag race at 307 km/h
The launch: 0 to 100 km/h
Off the line, the 911 Carrera 4 GTS Cabriolet hits 100 km/h in 3.65 s versus 4.93 s for the EX40 Twin Motor AWD. At this point, the 911 Carrera 4 GTS Cabriolet leads by 1.28 s and sits roughly 15 m ahead.
From 100 km/h to 400 metres
At 200 metres, the 911 Carrera 4 GTS Cabriolet is doing 162 km/h against 144 km/h for the EX40 Twin Motor AWD. The gap is 1.12 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Carrera 4 GTS Cabriolet crosses the line in 11.55 s versus 13.14 s. The 1.60 s gap represents roughly 77 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 GTS Cabriolet continues to build its lead. At 600 metres, it runs at 224 km/h versus 180 km/h. At 1,000 metres, the 911 Carrera 4 GTS Cabriolet finishes in 20.93 s versus 25.14 s, with a 4.21 s lead.
What the numbers don’t tell you
Both rivals are electronically governed, but not at the same level: the 911 Carrera 4 GTS Cabriolet is capped at 307 km/h, the EX40 Twin Motor AWD 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.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.26 kg/hp vs 5.17 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 7.30 seconds. The 1.28 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Porsche 911 Carrera 4 GTS Cabriolet has a clear edge over the Volvo EX40 Twin Motor AWD to 100 km/h. This difference is clearly noticeable in spirited driving and widens on standing starts.
