The start: 0 to 100 km/h

Off the line, the Panamera GTS hits 100 km/h in 3.93 s versus 4.43 s for the 911 Carrera Cabriolet. At this point, the Panamera GTS leads by 0.50 s and sits roughly 10 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Panamera GTS is doing 151 km/h against 153 km/h for the 911 Carrera Cabriolet. The gap is 0.37 s. The challenger starts to claw back ground.

At 400 metres standing start, the Panamera GTS crosses the line in 12.12 s versus 12.42 s. The 0.30 s gap represents roughly 16 m of track - two to three car lengths.

Beyond 400 metres: top speed comes into play

Past 400 metres, the gap narrows.

At 1,000 metres, the Panamera GTS finishes in 22.14 s versus 22.28 s, with just 0.13 s to spare. The 911 Carrera Cabriolet fails to fully close the launch gap.

What the numbers don’t tell you

The Panamera GTS features all-wheel drive (AWD) against the 911 Carrera Cabriolet’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.

Both rivals share the same electronic speed cap: the Panamera GTS and the 911 Carrera Cabriolet are governed to 291 km/h. At that speed, standard-fit tyres approach their safety threshold - an industrial ceiling common to most electric vehicles in this segment. Neither car shows its true aerodynamic potential in this duel.

With two combustion powertrains, the difference comes down to power-to-weight ratio (4.49 kg/hp vs 4.00 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.39 seconds. The 0.50 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
