Off the line, the 911 Turbo Cabriolet hits 100 km/h in 3.14 s versus 4.77 s for the Boxster Spyder. At this point, the 911 Turbo Cabriolet leads by 1.63 s and sits roughly 16 m ahead.
At 200 metres, the 911 Turbo Cabriolet is doing 169 km/h against 151 km/h for the Boxster Spyder. The gap is 1.31 s. The challenger starts to claw back ground.
At 400 metres standing start, the 911 Turbo Cabriolet crosses the line in 10.93 s versus 12.69 s. The 1.76 s gap represents roughly 89 m of track - a gap visible to the naked eye.
Past 400 metres, the 911 Turbo Cabriolet continues to build its lead. At 600 metres, it runs at 235 km/h versus 210 km/h. At 1,000 metres, the 911 Turbo Cabriolet finishes in 19.88 s versus 22.73 s, with a 2.85 s lead.
The 911 Turbo Cabriolet features all-wheel drive (AWD) against the Boxster Spyder’s RWD. At low speeds (0-30, 0-50, 0-80 km/h), AWD doubles the driven contact area: all four wheels transmit torque to the road, virtually eliminating wheelspin at launch. This traction advantage is decisive in the range where the motor delivers peak torque, before power and aerodynamics take over.
Electronically capped at 319 km/h, the 911 Turbo Cabriolet never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.
With two combustion powertrains, the difference comes down to power-to-weight ratio (3.04 kg/hp vs 4.01 kg/hp) and transmission (Automatic vs Automatic).
In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.74 seconds. The 1.63 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
Over 0–100 km/h, 911 Turbo Cabriolet 991.2 wins (3,14 s vs 4,77 s).
