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.

Genesis cars win accolades, offer value — so why are sales so bad?

My high-school buddy Brent Cormier was so smitten with the Genesis G80 when he saw it at an event I hosted at SXSW in 2016 he bought a used 2013 Hyundai Genesis a short time later and fell in love with the car. "It surpasses my every expectation," said Cormier, a self-described "renaissance man" who owns and runs a real estate agency with his wife Laura, is a food service executive chef and part owner of Austin-based Thin the Herd Guitars. "I was locked into Mercedes and Audi for 10 years," he added. "And felt trapped in an endless pit of maintenance costs." After owning the Genesis over the past two years — including using it as an Uber and Lyft driver to earn extra cash — Cormier learned what some frugal luxury sedan buyers and a handful of car reviewers have discovered: Genesis offers great bang for the buck compared to other premium brands and can compete with the best in terms of performance, features and comfort. Hyundai's luxury brand also earned a prominent third-party endorsement last week when for the first time Genesis topped J.D. Power's 2018 APEAL study, surpassing German luxury-performance icon Porsche. The APEAL study (which stands for Automotive Performance, Execution and Layout) "measures owners' emotional attachment and level of excitement across 77 attributes," ranging from performance to comfort, and asks nearly 68,000 owners of new 2018 models to score vehicles on a 1,000-point scale. In its second year ranked as a stand-alone brand, Genesis earned an APEAL score that bumped it up 15 points to 884 and helped push it past Porsche — and past BMW, Lincoln, Mercedes-Benz, Audi, Volvo, Cadillac, Land Rover and Lexus, in order of ranking. Last month, Genesis also topped J.D. Power's Initial Quality Survey (IQS) for the first time this year. And both its models were awarded Top Safety Pick Plus ratings by the Insurance Institute for Highway Safety, among 11 Plus ratings in all for Korean vehicles. Despite high J.D. Power rankings and great reviews, Genesis U.S. sales were off 50 percent for the first six months of 2018 compared to 2017, and in June Genesis sold only 796 vehicles — the first time U.S. numbers dropped below 1,000 in a month. Part of Genesis's APEAL and IQS success can be attributed to its small product lineup: just two models, the G80 and G90 sedans, with a third, the 2019 G70, launching later this year. And while those numbers may help in J.D.

Porsche 911 GT3 RS revealed in patent photos

Porsche has been taking its time developing the most hardcore 911 models for the latest 991 chassis. While the GT3 has been on the market for a little while, it suffered from some teething issues. The 911 GT3 RS is certainly on the radar since being spotted testing, but it's always better to get a look at a new car without all of the camo to hide the coolest parts. Thankfully, Car in the UK has some patent photos of the RS ahead of its debut, and they show off one mean-looking 911.
The first thing that you notice about the RS is that Porsche clearly isn't afraid to rework the latest 911's shape for its track-focused version. Each piece is slightly resculpted to squeeze the most out of it. Up front, the air dam has the same shape to the earlier photos. They also both highlight the upcoming model's tiny air inlet at the tip of the hood, the massive intakes in the rear fenders and general design of the rear wing with a ducktail underneath. The bubbled roof is much clearer here, where it was disguised in spy shots. You can also spot the slashing fender gills behind the front wheels that are a completely new feature.
The GT3 RS is the ultimate naturally aspirated 911 for the street, but according to Car, Porsche aims to take that even farther with the latest model. If these are the looks, then it's working. Unfortunately, the new version's powerplant remains a mystery. Though, given all the changes to the bodywork, the engine is almost surely getting tweaked over the 475-horsepower GT3. The RS is rumored to hit the road and be screaming down the track in 2015.
