Porsche Taycan GTS vs Porsche 911 GT3 RS 991.1: which is truly faster?

Off the line, the Taycan GTS hits 100 km/h in 3.65 s versus 3.85 s for the 911 GT3 RS. The instant torque of 850 Nm from the electric motor makes the difference. At this point, the Taycan GTS leads by 0.21 s and sits roughly 4 m ahead.

At 200 metres, the Taycan GTS is doing 156 km/h against 164 km/h for the 911 GT3 RS. The gap is 0.03 s. The challenger starts to claw back ground.

At 400 metres standing start, the 911 GT3 RS crosses the line in 11.57 s versus 11.75 s. The 0.18 s gap represents roughly 10 m of track - barely a car length.

Past 400 metres, the 911 GT3 RS continues to build its lead. At 600 metres, it runs at 232 km/h versus 219 km/h. At 1,000 metres, the 911 GT3 RS finishes in 20.63 s versus 21.32 s, with a 0.68 s lead.

The Taycan GTS features all-wheel drive (AWD) against the 911 GT3 RS’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 249 (i.e. 155 mph - industry threshold) km/h, the Taycan 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.

Instant electric torque gives an advantage off the line. The higher top speed of the combustion engine gives an advantage over longer distances. The distance at which one catches the other depends on the top speed differential.

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 5.53 seconds. The 0.21 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
