Porsche gives GT3 owners extra year of warranty, new engines in production April 22

While the auto industry reels from massive recall after massive recall, Porsche has quietly been working on a fix for an issue that's forced owners of the new 911 GT3 to park their track-ready rockets for fear of an engine fire. Thanks to a leaked letter from Porsche to a GT3 owner (which has been certified as real), we now have an idea of just where the German brand is at with the fix.
On April 22, Porsche will begin production of a new batch of GT3 engines for the 785 affected models across the globe. As you'll recall, the original issue rested with a screw joint that could loosen the connecting rod. The new engines have an "optimized piston rod screw connection," that should keep the connecting rod in place. Once technical validations are completed, production will kick off and new powerplants will be shipped around the globe for owners of the troubled cars.
Porsche will hand out a certificate to owners of affected cars once repairs have been completed, as a means of documenting the work. To make up for the trouble, Porsche will be giving owners an extra year on their new-vehicle warranty, while the 911 GT3 concierge will be reaching out to compensate them for having to park their car for so long.

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.
