Porsche 911 GT2 RS vs. Mercedes SLS AMG Black in battle of who can shred more rubber

We might be looking at the end of an era in European performance models. Mercedes-Benz is doing away with the SLS in favor of a rumored smaller and cheaper SLC, and Porsche has said that a new 911 GT2 isn't necessarily a sure thing, which means another 911 GT2 RS is even farther away. In its latest video, Evo's Jethro Bovingdon pits the ultimate versions of these German sports coupes against each other and finds two of the fastest cars the magazine has ever lapped around its track.
In one corner, there is the Mercedes SLS AMG Black Series that sits as the pinnacle of the company's halo model. It relies on the classic setup of a V8 mounted in front powering the rear wheels. On the other side, there is the 911 GT2 RS with a turbocharged flat-six mounted at the back, spinning the rear wheels. It was conceived to be Porsche's ultimate expression of a turbocharged 911, and while it's a few years old, Bovingdon shows that it's up to the task of racing a more modern rival.
Both of these rear-wheel-drive monsters are more than capable of some fantastically smoky power-slides, but they also show how great the last generation of sports cars was. Scroll down to check out the video.

Chris Harris pits Aston GT12 vs 911 GT3 RS vs McLaren 650S

The Geneva Motor Show is never lacking in exciting performance machinery. And this year was no exception. Our eyes, like those of Chris Harris, were drawn by two hardcore, track-focused versions of existing sports cars. Both wore the name GT3, and now Harris has brought them together for a supercar shootout. And he's thrown one more in for good measure. Those natural rivals are the Aston Martin Vantage GT12 and Porsche 911 GT3 RS, the latter manufacturer having pressed the former to drop the GT3 name to which it claims exclusive domain. There's a great deal that separates them, of course: one's got a V12 up front, the other a flat-six way in the back. But what binds them together is a common approach of taking an existing model, stripping it down, and tightening everything up to make it more of a weapon than a grand tourer. What that means in the Aston's case is a rather high price tag, much higher than that of the Porsche. But scarce demand and speculation on the open market have left British customers, at least, paying as much for the GT3 RS as for the limited-edition Aston. And that takes both into proper supercar territory. So to show what else that kind of money can get you, Monkey has brought along a McLaren. Not the similarly track-focused 675LT, but the standard 650S... Spider, no less, and with worn hard rubber. So which one performs best on the road? Which clocks the fastest lap time on the track? And which gets Harris' vote? You'll have to watch the video for yourself to find out, but it's well worth the 25 minutes of your lunch break.

2013 Porsche 911 RSR makes official debut

Porsche is ready to go racing in 2013, showing off a new 911 RSR today that is scheduled to compete in several endurance events this year. Based on the current 991 911, the new RSR will compete in the 2013 season of the World Endurance Championship and the 24 Hours of Le Mans. It will not, however, make an appearance in a North American racing series this year.
The 2013 version of the racecar has increased in wheelbase by some four inches, features a new wishbone front suspension in place of the last-generation's McPherson strut setup and boasts a new, lightweight six-speed racing gearbox. The engine, meanwhile, is an "optimized" version of last year's car, a 460-horsepower 4.0-liter boxer six-cylinder. Extensive use of carbon fiber and polycarbonate windows help the RSR shed weight, and Porsche has also balanced the weight more evenly with a lower center of gravity.
Porsche has thoughtfully dedicated some space to celebrate the 911's 50th Anniversary, with the number 50 clearly visible in the top-down view of the RSR, as well as along the doors. Scroll down to read the full Porsche press release, below.
