See what the Chevy C7 ZR1 may be benchmarked against

One of the greatest things every Corvette has had going for it, and also one of the most re-used arguments against it, is its price-to-performance equation - long before the Nissan GT-R became the de facto Porsche 911 comparator the Corvette spent decades as Exhibit A. Depending on which side of the argument you stressed, supporters crowed about how much performance you got for how (comparatively) little, detractors carped on how little you got everywhere else in the bargain.
It appears Chevrolet is working as hard as ever to render the argument meaningless. Spy shooters at KGP captured a convocation of European birds of prey leaving the General Motors test center, and aimed at benchmarking the C7 Corvette ZR1. The road train comprised of two C7 Corvette Stingrays, a 2013 Corvette ZR1, McLaren MP4-12C, Ferrari 458 Italia, Audi R8 V10 Spyder and Porsche 911 Carrera S and it was last seen heading down the same kinked-up back roads used to hone the Corvette Stingray.
The C7-series ZR1 and its possible 700 horsepower are still a ways off. If it really is being positioned to compete with the celestial exotica in the testing group, could it be the first Corvette to regularly be the first answer to the question "Cost no object, which would would you rather have?"

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.

Porsche considering turbo for new GT3 RS [w/poll]

Some automakers make one hardcore version of a sports car and are done with it. Or at least they make one at a time. Think Ferrari 458 Speciale, Lamborghini Gallardo Superleggera (or Super Trofeo Stradale or Squadra Corse) or Maserati GranTurismo MC. But not Porsche. It transforms the 911 into the hard-core GT3, the even harder-core GT3 RS, the you've-got-to-be-psychotic GT2 and the do-you-have-a-death-wish GT2 RS. The RS models take things to a further extreme, but what separates GT3 from GT2 models has traditionally been the use of foced induction: GT3s are naturally aspirated, while GT2s go turbo. But that could all be about to change.
According to the rumors making their round of the webosphere, Porsche is considering using a turbocharged engine for the next GT3 RS. The reason is that, as we all know, Porsche has already pushed the 3.8-liter flat-six in the existing GT3 about as far as it can go, and then some. And buyers expect not only a more bare-bones package with the GT3 RS, but also a bit of extra power.
Given that everything seems to be going turbo these days, the move might make some measure of sense, especially if Porsche wants to avoid with the GT3 RS the spontaneous combustion issues it faced with the GT3. But we can't help but wonder why, at that point, it wouldn't just skip the GT3 RS and go straight for the GT2.
