2025 Porsche 911 GT3 992.2 vs GT3 992.1 Exhaust Sound

The new Porsche 911 GT3 features a 4.0-liter, naturally aspirated engine designed to meet stricter emissions standards, utilizing two particulate filters and four catalytic converters. Despite the more robust emission controls, the engine still roars powerfully as it revs up to 9,000 revolutions per minute. Borrowing the camshaft profile from the 911 GT3 RS, along with revised cylinder heads, optimized throttle body butterfly valves, and enhanced oil coolers, this powerhouse produces an impressive 502 horsepower. The result is a balance of performance and sound, but enthusiasts will be eager to compare it with the previous generation model to see if there are any noticeable differences.
