WE TESTED THE NEW PORSCHE 911 CARRERA GTS AND FOUND THAT IT OUTGUNS THE OLD VERSION
- In our testing, the 2025 Porsche 911 Carrera GTS coupe is three-tenths of a second quicker to 60 mph than the 2022 version of the same car.
- The extra speed comes despite the GTS adding 239 pounds between the 992.1 and 992.2 generations.
- We expected the weight gain to add roughly two-tenths of a second to the 60-mph time, but the hybrid's 64-hp boost has the opposite effect.
Welcome to Car and Driver's Testing Hub, where we zoom in on the test numbers. We've been pushing vehicles to their limits since 1956 to provide objective data to bolster our subjective impressions (you can see how we test here).
Before talking about how horsepower, torque, and grip levels affect acceleration, it's important to note that the weight of a car is closely related to its ability to accelerate. Because the heavier a vehicle is, the larger the force required to increase its velocity becomes. The logic behind that truth has set endless teams of automotive engineers down the path of shaving weight from their automobiles. And, despite adopting a hybrid powertrain and gaining 239 pounds between the 992.1 and 992.2 generations, the Porsche 911 Carrera GTS coupe hits 60 mph three-tenths of a second quicker than its predecessor in our testing. Both our test cars featured an eight-speed dual-clutch automatic, which is the only transmission available in the new hybrid model.
Three-tenths of a second may not sound like a lot, but when we're talking about a car moving from a launch-control-enabled 2.8-second 60-mph sprint to 2.5 seconds in the span of a single generation, that's something worth noting. And that's exactly what Porsche did between the last 911 GTS coupe we tested in 2022 to the most recent model we tested earlier this year.
Interestingly, while the old car was powered by a twin-turbo 3.0-liter flat-six and the new car by an enlarged 3.6-liter with a single turbo, Porsche says the new engine is actually lighter by about 40 pounds. Of course, the extra weight has to come from somewhere, and the secret behind the added fat is also the secret behind the 2025 model's impressive acceleration: the new T-Hybrid system.
On its own, the turbocharged 3.6-liter spits out 478 horsepower, only five more than the old 3.0-liter, but the electric motor incorporated into the PDK gearbox can add a continuous 53 horsepower or up to 64 ponies in 10-second bursts. With the electrons involved, the new GTS churns out a combined 532 horsepower and 449 pound-feet of torque, improvements of 59 and 29 compared with the old GTS.
Continuing beyond 60 mph through the quarter-mile, the new version's advantage stays the same. The 2025 GTS rockets through the marker in 10.6 seconds at 131 mph, with the 2022 car doing the deed in 10.9 seconds at 128 mph. The hybrid system makes an even bigger difference when accelerating from a roll, with the 3638-pound 2025 model needing just 3.1 seconds in our 5-to-60-mph test compared with 3.9 seconds for the 3399-pound 2022 model. The newer model wins out in top-gear accelerations too, needing just 2.5 seconds in our 50-to-70-mph test compared with the older model's 2.7 seconds.
Want to stop or add a corner into the mix? The new version still has you covered. Stops from 70 mph to zero require just 140 feet in the new car, three fewer than the old model. The 2025 model outperforms on the skidpad as well. Our 2025 test car wore a set of Goodyear Eagle F1 SuperSport R summer tires sized 245/35R-20 up front and 315/30R-20 at the rear, which resulted in it posting 1.07 g on the skidpad. Wearing a set of Pirelli P Zero PZ4 shoes (similarly sized except for being 10mm narrower at the rear), our 2022 car managed a still mighty impressive 1.06 g.
Despite the new GTS's extra weight, there's no denying that Porsche found a way to improve performance with the T-Hybrid system. Acceleration figures aside, the hybrid aspects blend seamlessly into the background, allowing you to take full advantage of their benefits without reminding you of the added complexity.
