Porsche Panamera GTS 971 vs Porsche 911 GT3 997.2: which is truly faster?

Off the line, the Panamera GTS hits 100 km/h in 3.93 s versus 4.08 s for the 911 GT3. At this point, the Panamera GTS leads by 0.15 s and sits roughly 2 m ahead.

At 200 metres, the 911 GT3 is doing 158 km/h against 151 km/h for the Panamera GTS. The gap is 0.03 s. The challenger starts to claw back ground.

At 400 metres standing start, the 911 GT3 crosses the line in 11.85 s versus 12.12 s. The 0.26 s gap represents roughly 14 m of track - two to three car lengths.

Past 400 metres, the 911 GT3 continues to build its lead. At 600 metres, it runs at 225 km/h versus 210 km/h. At 1,000 metres, the 911 GT3 finishes in 21.23 s versus 22.14 s, with a 0.91 s lead.

The Panamera GTS features all-wheel drive (AWD) against the 911 GT3’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 291 km/h, the Panamera GTS 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 (4.49 kg/hp vs 3.16 kg/hp) and transmission (Automatic vs Manual).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.06 seconds. The 0.15 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
