Jay Leno puts carbon fiber wheels to the test on a Porsche 911 GT3 RS

Jay Leno's Garage usually focuses on looking at cars new and old, speaking to their owners and then Jay taking a drive to see what he thinks. However, Leno throws his usual shtick to the curb this week to do a full product test of the carbon fiber wheels from a company called Carbon Revolution. If you're not interested in hearing about wheels for 18 minutes, don't worry. They get mounted on a Porsche and are tested back-to-back with stock wheels, and Leno takes the 911 for a track test, too.
While carbon-fiber wheels aren't exactly a new idea, Carbon Revolution's goal is to create a lightweight, one-piece product that can be mass produced. The company even claims that it already has a deal with an OEM automaker to offer them on a vehicle in a few years. The key to the technology is that it doesn't need an expensive autoclave to be made.
In the meantime, the company's carbon fiber wheels are available as an aftermarket option for about $15,000 a set, according to the video. They weigh in at about 15.5 pounds each and offer OEM-levels of stiffness, so they could cut some unsprung mass off of a performance car. Watch here as Jay and his mechanic Bernard lap Willow Springs and give their feedback about what they think of this cutting-edge technology.

Fastest and most powerful SUVs in America for 2022

Here in the United States, we enjoy power almost as much as we like our SUVs. Thankfully, we’ve got plenty of both. Traditionally, the most powerful SUVs source their massive horsepower and torque from some form of a V8. While thatÂ’s still generally the case, electrification comes into play more and more, whether itÂ’s mild-hybrid tech, a plug-in hybrid powertrain or, as is the case with the two vehicles topping this list, fully electric vehicles. As we enter the 2022 model year, letÂ’s look at the most powerful SUVs available.  Before we dive in, letÂ’s address the elephant that is waiting just outside the door. Due to supply shortages, Mercedes-Benz is shelving most V8 models for the 2022 model year. Some 2021 models can still be found in dealer inventories, but we wonÂ’t include them. With that in mind, letÂ’s dive into the list. 2022 Audi RS Q8 — 591 hp / 190 mph Read our review of the Audi RS Q8 The only Audi on this list is a hot little number, which we characterized as “an uncompromising option in a field of compromised options.” Powered by a 4.0-liter twin-turbo V8 (which seems to be a popular format in this list), its 591 hp and 590 lb-ft of torque get it scootinÂ’ to 60 mph in just 3.7 seconds, and on to a top speed of 190 mph. It even has the bragging rights of holding the Nurburgring lap record for an SUV.   2022 Rolls-Royce Cullinan Black Badge — 592 hp / 155 mph (limited) Read our review of the Rolls-Royce Cullinan This is one SUV where being a passenger might be more exciting than sitting in the driverÂ’s seat, thanks to over-the-top luxury — what do you expect from a car that costs over $350,000? The driver doesnÂ’t go unrewarded, though, with a turbocharged 6.75-liter V12 at their disposal. Thanks to the Black BadgeÂ’s software upgrade, it makes 592 hp and 664 lb-ft of torque to help get to its electronically limited top speed of 155 mph that much quicker.    2022 BMW Alpina XB7 — 612 hp / 180 mph Read our review of the BMW Alpina XB7 Alpina takes already impressive BMW vehicles and turns them into even more powerful, more luxurious machines. The Alpina XB7 improves upon the BMW X7 with a biturbocharged 4.4-liter V8 offering up 612 hp and 590 lb-ft of torque. ThatÂ’s good for a 4.0-second 0-60 sprint and a 180-mph top speed. Alpina also adds its own transmission and drivetrain tuning, upgraded suspension, exhaust and a whole slew of unique appearance touches.

2016 Porsche 911 R First Drive

Competition has forced the 911 GT3 RS to prioritize lap times over driving enjoyment. The 911 Carrera line has softened, now full of GT cars rather than the wild children of yore. Turbocharging is hitting the rear-engine Porsche en masse. All of this gave Porsche Motorsport a vacuum of emotion and purity to fill with just 991 examples of its glorious 911 R, a machine focused on putting unadulterated feel and enjoyment back into driving. Even amongst the diehard Porsche fraternity, just going faster doesn't work for everybody. They don't all want the thrill that comes from a high-downforce car running out of grip inches from a concrete wall. Not everybody loves suspensions so tied down that the slightest bump threatens the front splitter's continued existence. And many don't love turbochargers or want a computer to shift gears for them. Fortunately, just such people live, breathe, and work at Porsche Motorsport. This part of the company makes its living building Porsche's fastest machines, like the Cayman GT4 and the 911 GT3 and GT3 RS. But in an era when the bulk of Porsche's profits come from SUVs, Porsche Motorsport also sees itself as the guardian of the parent company's soul. Motorsport has enough pull that when it tells Porsche's board it needs a car like the 911 R the board listens. The quickest way to turn the 911 into a driver-connected car was to pull the weight out, and the easiest way to do that was to use the 911 GT3 RS as the basis. So it gets that car's magnesium roof, polycarbonate side and rear glass, carbon-fiber bonnet and front fenders, and lots of aluminum. The air conditioning got thrown out (you can pay to put it back in), as did the multimedia screen (ditto), the audio and navigation systems (ditto, ditto), the rear seats, and even the interior door handles. Cloth straps replace the latter so you can still get out of the car. At 3,020 pounds, the R is 110 lighter than the race-bred GT3 RS. Eschewing turbocharging in the interest of car-lover must-haves like induction noise, butterfly chirps, intuitive throttle response, and purity of sound, the 911 R simply borrowed the GT3 RS's 4.0-liter flat-six. So there's 500 horsepower of engine playing for keeps, the car ripping to 60 mph in 3.7 seconds from a standing start, hitting 124 mph in 11.6 seconds, and continuing on to 201 mph thanks to the lack of a monster, drag-inducing rear wing. The dry-sump engine revs and revs and feels like it wants to keep revving forever.
