Porsche Engineer Sheds More Light On The 992.2 2025 Porsche 911 Carrera GTS

A Break-Down Of Porsche’s New T-Hybrid System

While the latest 911 has now gained 50 kg (103 pounds), the system itself relies on a lightweight, high power-to-energy ratio battery with a tiny 1.9-kilowatt-hour capacity. The 992.2 GTS’ all-new 3.6 liter flat-6 engine has a wider bore and a longer stroke than the engine in the outgoing GTS, and it’s also just got one single turbocharger, instead of the twin turbos in the old car. The system’s centerpiece, however, is the new e-Turbo.

Unlike a conventional turbo with delayed spool-up, this one employs an electric motor for near-instantaneous power. This results in a driving experience akin to a large, naturally aspirated engine. You now get 541 horsepower, which is 61 horsepower more than the 992.1 911 GTS, and it has 570 Nm (420 lb-ft) of torque, which is 40 Nm (30 lb-ft) more than the old car.

Further to this, there is an additional electric motor that has been integrated into the 8-speed PDK, for boosting and recuperating power. Clen also elaborates on the system’s real "magic" happening at high RPM ranges. Here, the system recuperates electric and thermal energy from the drivetrain, converting it into up to 11 kilowatts and feeding it back into the electric motor. This not only provides a direct boost but also replenishes the battery’s energy, allowing for the modest battery size to work in combination with the electric motor.

The conversation then shifted towards how the engineering team’s key goal was: staying under 1,600 kg (3,274 pounds) curb weight. Clen confirmed this as their "magic number," a weight limit crucial to preserving the 911’s athletic character. The 911, he emphasized, is so much more than just straight-line speed; it is about an emotional connection forged through dynamic handling, something that Jack experiences later in the video, on the race track. Clen proudly shares their success, in achieving a curb weight of 1,595 kg (3,516 pounds) for the coupe version. This accomplishment, coupled with an impressive 8.7-second performance gain over the predecessor around the famed Nürburgring.

The pair then explored the broader perception of hybrids, particularly the negative connotation in the United States. Clen countered this view by highlighting that the battery’s real role is to eliminate turbo lag and also power the car’s suspension system. Further substantiating this, Clen says that the redesigned 3.6-liter 9A3 engine not only addresses weight reduction but also facilitates powering the PDCC (Porsche Dynamic Chassis Control) system using the high-voltage battery. This further enhances the PDCC’s responsiveness, leading to a more agile suspension system and an improvement in both comfort and overall performance.

The final sequence of the video is presenters Mark and Jack hitting the street and the track in the Carrera and GTS, with Porsche test driver, Jörg Bergmeister giving the new 911 a proper thrashing around the Estoril circuit in Spain.
