Some cars are fast. The 2025 Porsche 911 GT3 RS is precise in a way that makes “fast” feel like an afterthought — and at a starting price of $241,300, it asks a serious premium for that precision.
From the moment the 4.0-litre flat-six spins past 8,000 rpm, the GT3 RS announces itself not with brute force but with a finely tuned scream. The naturally aspirated engine produces 518 horsepower and 343 lb-ft of torque, redlining at 8,500 rpm. Porsche quotes 0-60 mph in 2.9 seconds and a top speed of 184 mph (296 km/h) — numbers that matter, but they only tell part of the story.
Price and trims
The 2025 GT3 RS starts at $241,300 MSRP in the US, before options. Popular additions — the Weissach Package, magnesium wheels, ceramic composite brakes (PCCB), and front-axle lift — routinely push a well-equipped example past $300,000. Used prices for the outgoing 992-generation GT3 RS currently hold well above MSRP due to limited allocation, so buyers looking for one on the secondary market should expect dealer markups rather than discounts.
A rolling wind tunnel
The active aerodynamics generate up to 900 kg of downforce at 285 km/h (177 mph) — more than double the previous-generation GT3 RS. On the circuit, the car feels pinned to the tarmac, cornering with a flatness that borders on the absurd.
“It does not so much turn into a corner as teleport to the apex.”
The DRS-style adjustable rear wing is more than a gimmick — it genuinely changes the car’s character from lap to lap, softening for straight-line stability and hardening for maximum cornering grip at the push of a steering-wheel button.
Weight and chassis
At 3,268 lbs (1,483 kg), the GT3 RS is heavier than a standard GT3 thanks to the aero hardware and structural reinforcements needed to handle the extra downforce, but Porsche offsets this with a carbon-fiber roof, hood, and rear wing as standard fitment. The result is a car that carries its weight low and central, which shows up most in fast, direction-change-heavy corners.
GT3 RS vs. GT3 vs. GT2 RS
Buyers cross-shopping the range should know where the GT3 RS sits: it trades the standard GT3’s everyday usability for outright downforce and lap time, while the turbocharged GT2 RS out-powers it in a straight line but can’t match its cornering precision. For anyone prioritizing track lap times over straight-line speed or comfort, the GT3 RS is the clear pick of the three.
