Wild Comparison Drive: 2026 Porsche 911 GT3 Street Car vs. 911 Cup Race Car, In Our Hands

Automotive journalists like to joke that the car industry’s toughest job belongs to the Porsche designer who is tasked with the next 911. How do you improve upon a car that has been around for so long and commands such a loyal following?

Likewise, the hardest job journo types face is reviewing the latest Porsche 911 GT3. The new one is basically perfect, just like the last one. Only better. This of course was the case when I recently strapped myself into a Cartagena Yellow 992.2 GT3 and set out for some laps on the small yet fun test track at the Porsche Experience Center Los Angeles, following behind lead instructor Johnny Kanavas in a Vanadium Grey Metallic GT3. The cars have the same power as the 992.1 version of the GT3—the car that won MotorTrend’s 2022 Performance Vehicle of the Year award—with probably the same weight, yet somehow the new GT3 is better. It’s sharper, easier to drive, better balanced, quicker, more lovable, more GT3. I don’t know how Porsche’s GT department does it. No one in the industry does.

The GT3 Somehow Gets Even Sharper

We were in PDK transmission-equipped cars with wings (not the GT3 Touring), and I left the gearbox in automatic mode and simply rotated the little steering wheel knob to Track. Unlike most transmissions on the market, Porsche’s PDK—when in Track mode—shifts itself in a nearly ideal manner. Yes, pulling the shift paddles is more satisfying, but my goal was to go as quickly as I could manage. The less thinking and doing, the better. After a few decent, nearly identical laps, my mind drifted back to a conversation I had with Le Mans winner Justin Bell while we were driving a C6 Corvette Z06 around Laguna Seca during the MotorTrend 2010 Best Driver’s Car Competition. I was praising the Chevy’s on-track prowess, and Bell said something like, “Yes, I’m the sure the Corvette is quicker after one lap, but I’m equally sure the Porsche GT3 RS will be quicker after 10.” To wit, I didn’t notice a change in the GT3’s behavior until the second corner of my ninth lap, and that simply felt like the tires were getting too hot. Just as easily, it could have been driver fatigue.

The tires, new for the 992.2-generation GT3, are Pirelli’s P Zero Trofeo RS, and they seem like a solid alternative to the usual-suspect Michelin Pilot Sport Cup 2R. Other changes to Porsche’s track car for the street include 8 percent shorter gears (the change is to the axle, so every gear in both the manual and PDK is shortened), retuned electric power-steering assist, new bump stops that allow for slightly more damper travel, anti-dive technology for the front end under braking, an aerodynamically enhanced trailing-arm suspension piece (yes, the suspension parts help out with aero—just like on the 992.1 GT3 RS), and revised damping, or PASM in Porsche speak.

All of that new-fangled goodness comes at a price: $239,850, which not too long ago was 911 Turbo S money. To be more accurate, a Turbo S was like $205,000. For the first time ever, a Weissach package is now available (it adds functional carbon fiber all around the vehicle and costs $28,310, unless you opt for the now foldable carbon-fiber bucket seats, then it’s $32,780), and Porsche claims this results in a 9-pound weight reduction. Yes, $28,310 for 9 fewer pounds. Further opt for the $17,840 magnesium wheels, and the weight savings grows to 48 pounds, or more than 10 unsprung pounds per corner. Since you’re obviously rolling in cash, you could further reduce unsprung weight by checking the box for the $10,370 carbon-ceramic brakes with yellow calipers. Want black calipers? That will be $11,330. Ain’t car configurators fun?

It’s difficult to argue with the results, though. I can’t think of another car you can jump inside and take to your personal limit as quickly and easily as a 911 GT3. It’s remarkable, really, bordering on magic. The biggest change in the 992.2 from where I sat was the anti-dive tech on the nose. Because the GT3 remains flatter while braking, you feel more efficient when turning, especially in a quick right-left situation, which Porsche’s L.A. track offers several times per lap. The new GT3 simply moves around less under braking. It seems as if high-speed stability has improved a touch as well (not that any GT3 has ever struggled in that department), because within a few laps I went from brushing the brakes for the kink on the long straight to only thinking about brushing said brakes at said location. Fun.

A Near-Perfect Track Tool—at a Price

But was it fun?

Look, I’m no spring chicken; I’ve been doing this professionally for more than 20 years, and I’m just not as into following instructors around racetracks as I once was. I just don’t care as much. Years ago, I got to chase David Donahue around Laguna Seca in matching McLaren 650Ss, and that was fantastic. Partially because Laguna Seca is a terrific racetrack, but also because I could feel myself improving each lap. I could see the speeds through Turn 1 rise repeatedly, until we were hitting more than 140 mph. In the GT3? Bored isn’t the right word, but I was thinking about all the concrete lining the tight track as much as I was about my kid’s upcoming birthday, two items that are sure to slow you down, Porsche GT3 or not. Plus, this Porsche Experience Center is across the street from where the Goodyear Blimp is moored (no, really), and I kept coming around corners and seeing the damn blimp slowly meandering above its base. It can be difficult to concentrate on the task at hand when a blimp is catching your eye, and I was relieved once I returned to the pits with an undamaged GT3.

Then the Real Race Car Showed Up

Next up was the new 992.2 911 Cup race car. There are a couple of things to know here. Yes, this used to be called the 911 GT3 Cup, but to cut down on confusion (caused by the fact that the 911 Cup does not compete in the actual GT3 class), the new version is simply called 911 Cup. What does that mean? Well, a 911 Cup car competes in one-make races (Porsche Cup cars only race against each other), whereas the even more hardcore 911 GT3 R competes in races—like the Rolex 24 at Daytona, the 12 Hours of Sebring, and the 24 Hours of Le Mans, etc.— against cars from other manufacturers. In a career filled with ridiculous stuff, I once flew to Portugal to drive the 992.1 GT3 Cup and 992.1 GT3 R on the old Estoril Formula 1 track, so I had some experience downward-dogging myself around the roll cage and into the racing seat. But man, was this thing a blast.

The 992.2 Cup car is an evolution of the previous car, and most of the changes just make good sense. For instance, the front splitter is now three pieces instead of one. Many “racing incidents” are going to involve the thing that sticks out in front of the car, so why replace the whole part when you can just replace one third of it? Likewise, the end caps on the extra-wide rear wing are now cheaper plastic instead of expensive carbon fiber. Why? Because the widest part of the car often gets tangled up with other racers. Almost all the body panels are made from “recycled carbon-fiber fleece” (yes, including the doors) mixed with a “bio-based resin.” The predictable result is that the 911 Cup is lighter than a GT3 road car.

It sure felt that way on the track, too. For this session, I’d be following Porsche factory-racing star Patrick Long, a multi-time Le Mans winner, co-founder of Luftgekulht, and co-star of the Oscar-nominated F1 movie. Odds are whenever I’m following Long around a track, I’m driving something cool. For example, once it was a Porsche 959.

From behind the wheel, there’s essentially nothing to mentally connect the GT3 to the 911 Cup. I guess the start button is in the same spot. While it may only compete against itself, make no mistake: The Porsche 911 Cup is a serious race car. And oh, was it a hoot and a holler on the track.

Blimp? What blimp? Suddenly I was dead focused on the task at hand, trying to catch Long and the 911 GT3 RS road car he was leading me with. This was fun. More than fun, after maybe four corners I was impressed by just how easy the new Cup car is to drive. In Portugal, I remember struggling in tight, second-gear corners as the car easily slid into oversteer situations. Here, on Porsche’s short track where nearly every corner takes place in second gear? Planted like a shrub. Some credit must be given to the sticky Pirelli slicks, which replace the Michelins on the previous iteration. But more mechanical grip is involved, too. The Porsche track’s surface is also better than Estoril’s notoriously (these days) slippery tarmac. Still, the car offered grip galore.

Why the 911 Cup Feels Notably Different

Indeed, it feels so much different that when we came in after the first session, Long commented that I was catching him in the corners. Yes! Of course, his race craft and skill meant he exited said corners 10 times better than I could ever hope to, which is why he was dusting me on the straights, not the extra 8 horsepower the GT3 RS has over the 911 Cup (520 hp versus 512). Besides, the Cup car’s weight-to-power ratio is far superior. Sometimes, kids, it is all down to driver talent. To illustrate that very point, at the start of the final lap, Long actually went flat out and left me in his wake. Hey, I wouldn’t want me getting too cocky, either.

Which almost was the case. That’s how confident I was in the 992.2 911 Cup after about a dozen laps. Aside from being reliable, the best thing a race car can be is easy to drive. Barrels of fun, too. That’s exactly what the new Porsche 911 Cup car is. So here’s saying nice works as always to the boffins in Flacht.
