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.

Porsche 911 R is made for the purist

Who wouldn't welcome a new version of the Porsche 911 with ultra-light weight, a GT3 RS motor, a stripper interior, and a core philosophy of driving fun over outright lap times? The iconic Porsche 911 has been getting larger and more complicated with each passing generation, and that hasn't sat well with every engineer at Porsche. So there's a ready market out there for 911 R, a limited-edition show stopper of just 911 cars, due to start production in Zuffenhausen, Germany, in May. It's a car that combines a unique version of the six-speed manual gearbox, plenty of raw, naturally aspirated flat-six power, and all the feel of a cut-price version of the 911 GT3 RS pseudo racer. Yes, Porsche is bringing the beloved six-speed stick back to the sharp end of the 911, even though the brand's quickest cars are now dominated by the seven-speed dual-clutch transmission (and the less loved seven-speed manual). Porsche insists that the RS is still the 911 to have if it's stopwatch-bashing you need to do. Instead, the 911 R developers focused on trying to give it the most driving purity it could cram in. The most traditional way for motorsport operations to do that has always been to rip out weight. And Porsche Motorsport didn't diverge from the plan. The 911's rear seats have been thrown out, along with a raft of other pieces Porsche Motorsport thought it could either do without completely, redesign to be lighter or stronger, or both. View 18 Photos The R cuts 110 pounds from the next-lightest 911 variant, hitting 3,020 pounds on the scales. The pound-cutting starts at the body and bores all the way into the 911 R's chassis components, though there are some obvious nods to the marketing department that survived the dietician's axe. There is a lot of 911 GT3 in the body, with a combination of a carbon fiber (bonnet and front guards), a magnesium roof, polycarbonate front and side "glass," and aluminum everywhere else. The R cuts 110 pounds from the next-lightest 911 variant, hitting 3,020 pounds on the scales. While the 911 R has lurid (and deletable) red or green racing stripes as standard, it's not supposed to be as wild looking as the GT3. Porsche replaced the GT3's adjustable, tall-standing rear spoiler with a more-subtle pop-up version, and the R uses a rear diffuser under the bumper to offset any loss of rear downforce. The rear seats are gone, and the two remaining seats use carbon fiber shells upholstered in tartan cloth (another nod to early 911s).

Porsche recalling 24,500 Panameras for a potential HVAC coolant pump issue

A possible coolant pump problem for the HVAC system is causing Porsche to recall 24,467 units of the Panamera from the 2017 to 2020 model years. Bentley's recalling 650 examples of the sibling 2020 Continental GT for the same issue. Porsche was notified of a malfunction in the external heat pump for the Panamera's climate control in December 2022. An automaker investigation found that it's possible for excess humidity or even liquid to get past the pump seals and short out the pump's circuit board and connector. In rare instances, the malfunction could cause a fire. This can happen even when the engine is turned off because the cars in question are equipped with a residual heat function that keeps warming the cabin after shutdown. Panameras built after July 26, 2021 were fitted with a different pump. The Stuttgart carmaker's field analysis showed "a very small number of instances of thermal damage possibly attributable to this issue." Bentley changed the part in July 2019 to a model with a pressure compensation seal. Porsche said it will begin notifying owners on March 27. It also said it will reimburse any Panamera owners who have paid to have the part fixed previous to this recall. The fix is a trip to the dealer for a new pump with better sealing, sourced from a new supplier. Bentley will begin notifying owners on the same day. In Bentley's case, though, the automaker says "A hardware change will be required but the final solution is currently under investigation and cannot be confirmed at this time." Since the automaker moved to a new pump that isn't part of the recall population, we aren't sure why a resolution remains under investigation. Porsche owners can contact Porsche customer service at 800-767-7243 and refer to internal recall number APA1. Bentley owners can call 800-777-6923 and refer to RE23/02 (RC67). Anyone in that group can go straight to the National Highway Transportation Safety Administration at 888-327-4236 (TTY 1-800-424-9153) or nhtsa.gov, citing campaign number 23V033 for the Panamera or 23V034 for the Bentley.
