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.

Mercedes-AMG GT vs. Porsche 911 [w/poll]

Mercedes-Benz designed the AMG GT to compete head-on with the Porsche 911. It's a clear, singular purpose, and Benz brings a lot of money, technology and race-bred expertise to the fight.
The AMG GT is Merc's followup to the awesome SLS AMG, the retro-modern, gullwing-doored coupe that took us by storm half a decade ago. But this new GT coupe is a more focused sports car than the SLS, rather than an all out supercar capable of extreme performance. It's got a brand-new V8 engine, and state-of-the-art technology that help it to not only be a proper Mercedes, but to be a serious performer.
Mercedes will sell its new baby in two models. The GT S arrives first, in spring 2015, followed by the standard GT in mid-2016. Of course, there's room to grow from there. And while Porsche may have already expanded its 911 range to include a vast variety of models, here's how Stuttgart's icon stacks up against Affalterbach's bad boy.

Five cursed and haunted cars

Any kid lucky enough to grow up in Detroit is familiar with the Henry Ford Museum. It's huge, full of shiny things and a great place to take a child and let them burn off some energy. After several field trips and weekend outings however, the dusty concept vehicles and famous aircraft tend to lose their punch for youngsters. As a fifth grader, I was already gazing on the museum's many gems with glassy eyes. On yet another school trip, we made our way to John F. Kennedy's death car, a gleaming black Lincoln limo. The aging volunteer docent told our little group something I had never heard before. "You know, this car is haunted. Several employees have reported seeing a gray presence right here," he said, pointing to the back passenger side seat. I perked up. Now here was something I had never heard before. A haunted car? Sure, it happened in Goosebumps, but this was real life. It made sense, in a way. Cars can be violent, emotional places. That's certainly the case with JFK's limo, as well as the other four cars on this list. And maybe those gut-wrenching deaths can permanently doom a car. 5. Archduke Franz Ferdinand's Graf & Stift Death Limo World War I tends to be a forgotten war, despite being pretty terrible in its own right and setting the stage for the entire 20th Century. The French forces, for instance, lost more lives in the first month of WWI than the US did in the entire Civil War. Everyone who has been through a freshman world history course knows the conflict started when Archduke Franz Ferdinand and his wife were shot by a Bosnian anarchist. The crazy thing is, Ferdinand had already avoided an attempt on his life that day, and was actually on his way to the hospital to comfort those who had been injured in the crossfire. One of the would-be assassins simply walked out of a cafe and saw his intended target sitting in front of him where the open-air limo had stalled. The archduke and his wife were shot through their heads and throats. Their deaths would not be the last caused by the limo. Throughout the war and into the 1920s, the limo was owned by fifteen different people and involved in six accidents and thirteen deaths, not counting the 17 million or so killed in the war triggered by the Archduke's assassination. The first person to own the car after the Archduke was an Austrian general named Potiorek, who went insane while riding in the car through Vienna.
