With the launch of the 2025 Porsche 911 Carrera GTS, the 911 lineup now includes a hybrid 911 model. This model is known as the 992.2, features a 3.6-liter T-Hybrid powertrain that utilizes an electrically enhanced turbocharger and an integrated electric motor/generator. Priced at $166,895.

Powertrain and Performance
The 2025 GTS introduces the 9A3B6 engine, an evolution from the 9A2B6 engine found in the 992.1. Engine displacement has increased from 3.0 liters to 3.6 liters.
The new engine employs an electrically enhanced turbocharger and an electric motor/generator. Power output rises modestly from 473 to 478 horsepower. Peak torque remains at 420 pound-feet. Maximum boost pressure increases from 18.6 to 26.1 psi.
The new hybrid 911 will be available in the high-performance 911 Carrera GTS model. It integrates an electric motor into the car’s eight-speed transmission, complementing the six-cylinder gas engine.
This combination allows the new hybrid 911 to produce up to 532 horsepower, an increase of 59 horsepower over the current Carrera GTS model.
Hybrid Integration
The electric motor/generator is integrated into the eight-speed PDK dual-clutch transmission. The T-Hybrid system uses a single, large, electrically boosted turbocharger, replacing the twin-turbo setup of its previous model.
The electric motor sandwiched in the turbo reduces turbo lag achieving full boost in less than a second at 2000 rpm.
Unlike Porsche’s other hybrid models, such as the Cayenne e-Hybrid and Panamera e-Hybrid, the 911 Carrera GTS is not a plug-in hybrid.
It will be a fully self-contained hybrid, charged solely by the engine and through regenerative braking without the capability to drive distances on electric power alone.
The ‘T-hybrid’ system focuses on enhancing performance rather than improving fuel efficiency. By eliminating turbo lag and providing instant power, the hybrid 911 system allows for a smoother and more linear power delivery. This performance boost is complemented by a modest 3g/km reduction in emissions.
Design and Engineering Innovations
The 9A3B6 engine has been redesigned for compactness from the top of the intake manifold to the bottom of the oil pan.
This redesign accommodates the power control electronics for the hybrid 911 components. The accessory drive is eliminated, the transmission-mounted motor functions as both the starter and generator.
The air conditioning compressor is driven by a 400-volt motor and the water pump is now integrated into the engine and driven by the oil pumps.
The exterior design of the hybrid 911 does not overtly signal its hybrid nature. There are no hybrid-specific badges or green brake calipers, though an optional ‘T-hybrid’ sticker is available.
The front bumper features venetian blind shutters that open and close for cooling and aerodynamic efficiency. Inside, the hybrid 911 elements are subtle with the hybrid display accessible via the touchscreen.
Weight-saving efforts have reduced the engine’s weight by 40 pounds. The 1.5-kWh lithium-ion battery weighs about 60 pounds and operates at 400 volts. The overall curb weight of the GTS coupe is 3536 pounds.
Porsche has managed to keep the weight increase to a minimum. The hybrid 911 system adds 50kg, much less than the 150kg a plug-in hybrid system would have added.
The total claimed curb weight of the hybrid 911 Carrera GTS is 1,595kg, just under Porsche’s target of 1,600kg.

Performance
Porsche claims a 0-to-60-mph time of 2.9 seconds down from 3.2 seconds in the previous model. Top speed has increased to 194 mph.
In real-world testing the new GTS covered 70.5 feet in the first 2.5 seconds from a standstill compared to 47.6 feet for the old model.
On the Nürburgring Nordschleife, the new GTS driven by Jörg Bergmeister clocked a time of 7 minutes and 16.9 seconds, 8.7 seconds faster than its previous model. The handling and grip of the car were improved, by powerful brakes and instant throttle response.
The base 992.2 Carrera retains the 9A2B6 engine but adopts the Lambda 1 philosophy for better emissions control.
Peak boost increases from 12.0 to 17.4 psi. Power output rises from 379 to 388 horsepower with torque remaining at 331 pound-feet.
A Porsche test driver took the hybrid 911 around Germany’s Nürburgring Nordschleife racetrack, clocking a lap time of 7 minutes and 17 seconds.
This is 8.7 seconds faster than the comparable current-generation Hybrid 911 Carrera GTS, indicating that the added weight of the batteries and electric motors has not hindered the car’s performance.
Interior and Exterior
New headlights incorporate all front lighting functions allowing for larger air intakes for the front-mounted radiators.
The GTS features active grille shutters and an active front diffuser to optimize airflow. The rear design includes a more integrated light bar, taillights, and Porsche script along with repositioned license plate cutout and engine grille adjustments.
A fully digital 12.6-inch instrument cluster offers various display options including a customizable center-tach, five-gauge layout.
Several new wheel designs are available with 19 and 20-inch diameters for the base model and 20 and 21-inch for the GTS.
The exterior design of the hybrid 911 does not overtly signal its hybrid nature. There are no hybrid-specific badges or green brake calipers, though an optional ‘T-hybrid’ sticker is available.
The front bumper features venetian blind shutters that open and close for cooling and aerodynamic efficiency. Inside, the hybrid 911 elements are subtle with the hybrid display accessible via the touchscreen.

Pricing and Availability
The base Carrera is priced at $122,095, a $6,000 increase from the previous model. The GTS starts at $166,895. The convertible version of the GTS adds $13,300, and all-wheel drive (available only on the GTS) adds $7,800.
Prices for the GTS start at £132,600 ($165,000), with higher costs for cabriolet, Targa top, or all-wheel-drive variants. The rear-wheel-drive version is quicker off the line due to its lighter weight and superior traction.
Advanced Features
The hybrid system in the hybrid 911 Carrera GTS, dubbed the ‘T-hybrid’ (T for turbo) includes a 1.9 kWh battery weighing 27kg located under the front bulkhead.
This setup powers two electric motors. One motor integrated into the eight-speed PDK gearbox provides a 55 horsepower, 110 foot-pound boost. The other, a smaller 14 horsepower motor helps to spool up the larger single turbo, eliminating turbo lag.
The hybrid 911 Carrera GTS hybrid features a 400-volt electric architecture that powers the car’s climate control, eliminating the need for a belt-driven air conditioning compressor.
This change allows the engine to rev faster and be slightly smaller and lighter. The engine is positioned 110mm lower, making room for a new lithium-ion battery for ancillaries.
The adaptive suspension benefits from the high-voltage system, reacting more quickly. The car’s nose-lifter now raises the front in one second flat compared to five seconds previously.
The hybrid 911 system maintains a 70% state of charge to ensure consistent performance. In Sport Plus mode, the system prioritizes using up the battery’s power quickly, calibrated to last an entire lap of the Nürburgring.
The unveiling of this hybrid 911 model comes nearly 60 years after the original 911 was launched in 1963. The 911 has remained a core model for Porsche, even as the company has expanded its lineup to include more SUVs like the Macan and Cayenne.
As sales of fully electric vehicles (EVs) have started to slow in the U.S., hybrids have become increasingly popular due to their greater fuel efficiency without sacrificing power.
This trend is attributed to the high prices of EVs and a lack of reliable public EV charging infrastructure. Hybrids generally more affordable and not dependent on chargers.
