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.

Super Bowl car commercials: Follow along as we riff on them live

Join Autoblog editors Sunday starting around 6:30 p.m. ET as we react to all of the car commercials during the game. We know Hummer, Porsche, Hyundai and others will have splashy ads, and naturally, there's usually a few surprises. Whether you're a Chiefs or 49ers fan — or don't care about football — the commercials are always a highlight. And for us, the car spots are the most intriguing. Weigh in with your own thoughts in the comments section. Let's kick off.   FIRST QUARTER Editor-in-Chief Greg Migliore liveblogs the first quarter. F9 We'll count this as a car commercial. The latest edition of the Fast & Furious looks like it well, will have cars. We'll punt on further comment. PORSCHE I like it. Creative. Sort of a Night at the Museum feel. The guards stage a theft and then a car chase. The Taycan looked good. Get fired up — the future for Porsche is electric. The spot is meant to illustrate how fun that can be. I don't need any convincing.    SECOND QUARTER Associate Editor Byron Hurd is liveblogging the second quarter.  HYUNDAI Hyundai checked in super early with their Sonata "Smaht Pahk" commercial, which manages to score points for being both cute and clever while also being a fairly good commercial in a vacuum. We saw it last week, so there were no surprises here, but we enjoyed it nonetheless.  Fun note: If you go to the Sonata landing page on Hyundai's web site, you can choose "plain old English" or "the Boston way" for your language; the latter will translate the page. Enjoy.  FORD Hi ho, West Coast Editor James Riswick here. Apparently, the guys in Detroit didn't get the Mustang Mach E ad featuring Idris Elba and a whole boat load of awesome old Mustangs. Pretty sure it's bound to be viewed the exact same way as the car itself: traditionalists will be aghast, while non-car people will be intrigued by a new, all-electric, crossover version of one of the few cars they've heard of.  GENESIS They're coming more rapidly now. Genesis gets some love thanks to Chrissy Teigen and John Legend; this was another known quantity, but Hyundai's luxury brand managed another solid entry here thanks to its choice of stars. Teigen and Legend got the chance to throw back to the latter's "Sexiest Man Alive" honors, which Teigen often teases him for. Another solid all-around spot.  GMC/HUMMER Are there just no surprises left? Don't tell me; I know the answer. LeBron James fronts the revived Hummer, which will be an EV sold as a GMC.

Porsche 911 Aerodynamic prototype cheated the wind ahead of its time

You might think that sports cars would have the lowest drag coefficient of all cars. And yes, they do tend to be more slippery than, say, SUVs or convertibles, but the sleekest vehicles on the road tend to be EVs, hybrids and luxury sedans. Sports cars, on the other hand, have aerodynamically detrimental needs for downforce and additional engine cooling. Still, the Porsche 911 is better than most, and has only gotten more so over the years. Its relatively narrow track and compact form mean it has a smaller frontal area than some other sports cars, and the gradual sweeping back of its headlights and windshield have only augmented its capacity for cheating the wind.
This 911 prototype, however, is even more aerodynamic than most. It's based on a "G model" 911 from 1984, but employed such features as covered wheels, a new rear spoiler and a reprofiled front end to drop its drag coefficient from 0.40 to 0.27, making it as slippery as a modern sedan and better at cheating the wind than just about anything built up to that point, save for maybe the Tatra 77, Citroën SM or Tucker Torpedo.
Elements of this prototype ended up gradually making it into production Porsches for years to come, and you can clearly see early influences on the second-generation 964 and even on the 959. It's featured here as the latest installment in a video series on rare historic Porsches unearthed from the company archives, following previous clips that featured a rare V8-powered 911 and a mid-engined 911 prototype. Scope out the latest episode in the video below.
