Porsche 911 GT3 997.2 vs Porsche Panamera 4 970.1: which is truly faster?

Off the line, the 911 GT3 hits 100 km/h in 4.08 s versus 5.77 s for the Panamera 4. At this point, the 911 GT3 leads by 1.69 s and sits roughly 11 m ahead.

At 200 metres, the 911 GT3 is doing 158 km/h against 128 km/h for the Panamera 4. The gap is 1.28 s. The challenger starts to claw back ground.

At 400 metres standing start, the 911 GT3 crosses the line in 11.85 s versus 14.11 s. The 2.25 s gap represents roughly 96 m of track - a gap visible to the naked eye.

Past 400 metres, the 911 GT3 continues to build its lead. At 600 metres, it runs at 225 km/h versus 177 km/h. At 1,000 metres, the 911 GT3 finishes in 21.23 s versus 25.94 s, with a 4.71 s lead.

Electronically capped at 256 km/h, the Panamera 4 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 (3.16 kg/hp vs 5.99 kg/hp) and transmission (Manual vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 9.39 seconds. The 1.69 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
