  • Porsche is preparing an updated version of the 911 sports car, which will be called 992.2.

  • In addition to a new hybrid system, it will also have a new 3.6-liter engine for certain models.

  • Expect to see the 992.2 appear within the next six months, going on sale as a 2025 model.

Due out early next summer as a 2025 model, the revised Porsche 911 will feature redesigned front and rear fascias, an updated cockpit and a few detail changes, including 48-volt hybrid systems across the engine range. But when it comes to breaking new ground for this 992.2 model, nothing beats the new T-HEV hybrid system that comes a little later and will bring the iconic sports car a big step closer to electrification. While Porsche has yet to confirm any details about the hybrid, two dealers we spoke to independently acknowledged the project’s existence but claimed deliveries wouldn’t begin before calendar year 2025.

Hybrid system

Unlike the plug-in hybrids Ferrari 296 GTB and McLaren Artura, the Porsche unit is intended for charging ‘on the fly’ and cannot be plugged into the socket. The electric motor can generate an additional 80 to 90 hp and is powered by a powerful Varta battery with a capacity of approximately 2.0 kWh. The software for the fast charging and discharging Porsche 400 volt system, inspired by the KERS technology used in F1, is said to have been developed in collaboration with Rimac (Porsche has a 45 percent minority stake in Rimac). The jointly designed T-HEV system combines two electrical elements. According to the supplier, the integrated starter generator provides an on-demand instant boost effect and powers the auxiliary equipment. The actual electric motor, located under the fuel tank, drives the front wheels and improves weight distribution.

The heart of the T-HEV system is a small battery that powers the compact electric drive unit. It is constantly charged, both by the combustion engine and by the kinetic energy generated during braking. For complexity reasons, a manual gearbox is not an option, sources say. The entire T-HEV module is claimed to weigh no more than 55 pounds. The engine in question is apparently a modified 3.0-liter twin-turbo six-cylinder, producing 395 hp and 347 Nm of torque. Assuming the electric motor contributes about 84 horsepower and 129 pound-feet to the action, combined output should be about 478 horsepower and 475 pound-feet of torque. Apparently an even more powerful 528 hp version is also in the works that would bridge the gap between the beefed-up future 911 GTS and the next 911 Turbo. According to the Weissach grapevine, the range-topping GT2 RS with more than 800 hp, expected in 2026, will also use a hybrid setup.

New engines for GTS and Turbo

According to various internal and external documents, the rest of the lineup will also see some significant engine changes. While the 3.0-liter twin-turbo six-cylinder will remain in the Carrera and Carrera S, the GTS will get a naturally aspirated 3.6-liter six-cylinder and the Turbo and Turbo S will trade their 3.8-liter engine for a more advanced model. twin-turbo 3.6-litre range-topper. The naturally aspirated 3.6-liter boxer is destined to eventually replace the 3.0-liter boxers, as well as the 4.0-liter engine unique to the GT3 twins and the S/T. The Carrera S and GTS will also use a 48-volt hybrid system.

Power from the essentially unchanged 3.0-liter in the base Carrera will increase from 379 and 331 pound-feet to 390 horsepower and 347 pound-feet. Next in line is the Carrera S, which reportedly climbs from 443 horsepower and 390 pound-feet to 454 horsepower and 406 pound-feet. Still according to the same semi-official source: the displacement of the GTS engine increases from 3.0 to 3.6 liters, but at 483 horsepower and 413 pound-feet the new VTCI variable-vane engine delivers only 10 horsepower more than today’s vintage, while peak torque drops by 7 pound-feet.

In a closely related scenario, the future 911 Turbo and Turbo S are tipped to swap the 3.8-liter boxer for a more advanced and economical 3.6-liter version. While the increased displacement appears to support Deputy CTO Frank-Steffen Walliser’s earlier statement that engine power will need to increase to meet stricter future emissions standards, the standardized bore and stroke will undoubtedly improve economies of scale.

The naturally aspirated 4.0-liter flat-six engine rated at a reported 503 horsepower and 347 pound-feet seems like the logical short-term evolutionary choice for the next GT3 and GT3 Touring. Peaking at 8,400 rpm, it would feature a 48-volt hybrid system, courtesy of Valeo. With no more than 5,600 units planned for the period 2024-2026, the charismatic high-revving 24-valve engine remains the coveted choice in the brand’s powertrain offering.

However, if our informant is right, the next GT3 version, scheduled for 2027, will switch to a more efficient 3.6-liter engine with virtually identical horsepower and torque, fully compliant with upcoming stricter European emissions regulations. Another source tells us that the redesigned GT3 will be an even rawer and purist example, a kind of modern interpretation of the minimalist 911 SC RS from 1984.

Design changes

Like the Macan EV and facelifted Taycan, the 992.2 will be almost a year behind schedule when it arrives in dealer showrooms just in time for the 2025 model year. While the sheet metal remains largely unchanged, almost all soft parts, including bumpers, wheels, lights, mirrors and aero aids, are new. The strikingly redesigned center front air intake is flanked by five adjustable vertical slats that can channel more cooling air to the radiators and brakes when necessary. On certain versions, the lower lip extends to increase downforce at high speed. As always, there are numerous model-specific front and rear bumper variants to choose from. While the Turbo and Turbo S have two pairs of exhaust pipes that differ in style and design, smaller models have center or side-mounted single or dual exhausts with chrome or black tips.

Further differentiation takes place through the Turbo, GT3, GT2 RS and Sport Design packages. The associated aerodynamic treatment, which is fixed or adaptive, ranges from a relatively small but full-width motorized air deflector at the rear to the RS’s extra-large and super-high semi-active wing. Apparently the split rear air intakes also apply to other versions. Last but not least, there are redesigned five-dot matrix headlights, complemented in the rear by stacked wraparound taillights and turn signals. The Porsche lettering in the center is illuminated at night; the split rear fog lights are located directly above it.

Inside, we noticed a new high-resolution fully electronic instrument cluster, which features five partially overlapping circular instruments, with the no longer analog tachometer and the larger digital speedometer in the center. It’s unlikely that a new operating system with more powerful software will arrive before the all-new 994, expected in 2027.

Where is the electric 911?

There’s talk of a radically redesigned electric generation 998 that was originally set to debut in September 2028. But based on what we’re hearing now, it’s now unlikely to see the light before the start of the next decade – think 2034, when the life cycle of the 992 replacement, called 994, ends. And even then, the battery-powered 911 won’t completely replace, but complement, its sister internal combustion models, which could potentially run on e-fuels by then.
