The ever-evolving Porsche 911 is getting ready for a mid-cycle facelift for 2024. Known internally as "992.2," the updated variant of Stuttgart's beloved sports car is apparently getting a new heart. A report from Car and Driver claims a 3.6-liter flat-six is coming in naturally aspirated and twin-turbo configurations.

This engine won't be an addition to the lineup, instead, it will replace existing engines. The reports has it on good authority the GTS will adopt the NA configuration with a mild-hybrid setup. That would represent a radical change given that the current 911 GTS has a twin-turbo 3.0-liter engine.

While the GTS' engine displacement could go from 3.0 to 3.6 liters, the Turbo models are downsizing from 3.8 to 3.6. The more potent variants are going to retain their twin-turbo setup, which currently sits at 572 hp and 553 lb-ft for the Turbo and 640 hp and 590 lb-ft for the Turbo S. Elsewhere, the GT3 is keeping its naturally aspirated 4.0-liter engine and a gaining a tiny power bump.

Car and Driver says the already confirmed electrified 911 won't be a PHEV, so you won't have to charge it yourself. The battery will be juiced up by the combustion engine and through regenerative braking. An electric motor good for up to 90 horsepower is expected to draw its juice from a tiny 2.0-kilowatt-hour battery pack, with the e-motor mounted underneath the gas tank and driving the front wheels.

The hybrid setup – which apparently won't add more than 55 pounds – will be based on a revised twin-turbo 3.0-liter flat-six engine producing an unconfirmed 395 hp and 347 lb-ft. Factor in the e-motor, and the total output is rumored to reach 478 hp and 475 lb-ft. A more potent 911 hybrid is apparently getting 528 hp, while the flagship GT2 RS could also be a hybrid with up to 800 hp.

Of course, we take all these rumors with a grain of salt. For now, there are only two guarentees: the 911 is going hybrid soon but a fully electric model won't happen this decade.
