The 2025 Porsche 911 GT3 has a new look and can now be bought with the lighter Weissach package. The 4.0-liter flat-six continues to deliver 502 horsepower, but torque decreases from 346 pound-feet to 331. Deliveries are set to commence next summer, with the base price increasing by almost $40,000 to reach $224,495. For 2025, Porsche made a few small changes to the famous 911 sports car’s design. The GTS model was the first to use a hybrid drivetrain. Porsche is currently giving the track-ready 911 GT3 new, lighter box seats, a more angular look, and updated suspension. Porsche will also add the Weissach package, which saves weight, to the GT3 for the first time. Business Continues as Usual The changes to the style are small, as usual for Porsche. The LED headlights have been changed, and you can choose to add a white trim ring. For more downforce, a new hood and underbody fins have been added to the front end. Because Porsche built all the lighting features into the main headlight unit, there is no longer a need for an extra LED strip in the bumper. This makes the air intake bigger. There are new air vents, a decklid, and a diffuser on the back. The side plates of the rear wings have also been changed. The naturally aspirated 4.0-liter flat-six engine stays behind the 911 GT3’s rear axle. Porsche says it was built with two particulate filters and four catalytic converters to meet stricter emissions guidelines. Power stays the same from 502 hp to 346 to 331 lb-ft of torque. For the same amount of horsepower, Porsche used the camshaft profile from the 911 GT3 RS and made changes to the cylinder heads. They also added new oil coolers and adjusted the butterfly valves in each throttle body. Don’t worry—the 4.0-liter engine can still go as fast as 9,000 rpm and can be paired with either a six-speed manual or a seven-speed PDK automatic gearbox. Porsche says that both gears have an 8% shorter final-drive ratio so that the cars can speed up. Manual-equipped GT3s can do the same run in 3.7 seconds and reach a top speed of 195 mph. PDK-equipped GT3s, on the other hand, should be able to go from 0 to 60 mph in 3.2 seconds. Porsche used the stricter GT3 RS as a model to figure out how to change the GT3’s suspension in 2025. Porsche says that the lower front axle position of the front ball joint on the lower trailing arm lowers pitching when stopping, making the car less likely to dive. The GT3’s anti-dive changes and teardrop-shaped trailing arms on the front axle keep the car’s aerodynamic balance while adding downforce at high speeds. GT3 Slimmed Down Thanks to its new silver metal wheels, the 2025 GT3’s unsprung mass has gone down by 3.3 pounds. The Weissach package will also come with magnesium wheels from Porsche, which will cut the weight by an extra 20 pounds. Porsche put in a new 12-volt lithium-ion battery, which made the car 9.9 pounds lighter than the old one. The GT3 still has 255/35ZR-20 tires up front and 315/30ZR-20 tires on the back. Inside the car, Porsche added new lightweight bucket seats with a thorax airbag and automatic height adjustment. The seat is heated, and the padding for the top can be taken off so that you can drive on the track while wearing a helmet. You can choose between 18-way power-adjustable sports seats and a lightweight carbon-fiber-reinforced plastic (CFRP) seat shell. The GT3 still has the traditional rotary ignition switch, but starting in 2025, the less expensive 911 Carrera models will have push-button starts. The digital gauge panel only shows important driving information and flashes to let you know when it’s time to shift gears when the car is in Track Screen mode. There is also a wireless charging pad inside the car, which will come in handy most of the time when you’re not racing. The GT3 Touring will also be back in 2025. The underbody strakes are changed to even out the aerodynamics, and the swan-neck rear wing is swapped out for an active rear spoiler with a Gurney flap that makes the car look less aggressive. The Touring model is the only one with an optional back seat because that’s what customers have asked for. Porsche now offers more leather upholstery options on the inside. The bucket seats have a backrest that can be folded down, which makes it easier to get to the back seats. Porsche is also adding the Weissach package to the 2025 GT3, which was only offered on the GT3 RS before. The anti-roll bar, coupler rods, and shear panel for the rear axle are all made of CFRP to keep their weight as low as possible. The door handles, side mirrors, roof, and back wing side plates are some other CFRP parts. The top half of the panel is covered with Race-Tex suede to cut down on glare. The GT3 Touring can also be ordered with the Lightweight package, which includes many of the same CFRP parts as the Weissach package, plus forging magnesium wheels. The shorter gear shift from the 911 S/T is used on Touring models with manual transmissions, and the Lightweight package adds a plaque inside the car that says “Leichtbau.” Dealers will be able to order the 2025 Porsche 911 GT3 at the end of this year. The cars should arrive in the summer of 2025. The GT3 costs $224,495, and the base price of the 2024 model will be more than $40,000 more.
