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?"

Porsche Cayman GT4 spotted at the N?rburgring

It was just the other day that we first caught wind of Porsche's plans to build a GT4 version of the Cayman, and now we're already looking at spy shots of the vehicle in question undergoing testing at - where else? - the Nürburgring.
With more aggressive front-end aero, a GT3-style air vent ahead of the front hood, a large wing at the back, and spindly alloys packed with over-sized brakes at each corner, this Cayman is clearly more extreme than even the range-topping GTS. The rear diffuser and central exhaust tips look about the same as those you'd find at the back of the Cayman GTS, though.
What we can't see, of course, is what Porsche has slotted in under the rear glass, how it's upgraded the interior and how much weight it's stripped out of the thing to get it down to fighting weight, but you can bet it'll come with a substantial power bump and a stripped-out interior with racing buckets and little else to open the gap between it and the GTS... and close the gap to the 911 GT3 which it will join as the baby brother in Porsche's performance-focused lineup.

Porsche 911 hybrid could get green light after all

The prospect of producing a hybrid version of the Porsche 911 has been on and off the table more times than we'd care to count. But before the year is up, the German automaker will make up its mind whether or not it will put the idea in motion. Porsche currently offers more plug-in hybrids than any other automaker. And according to Porsche CEO Matthias Muller in speaking with Automotive News, the opportunity exists to expand the powertrain technology to every model in the company's lineup, including the 911. The sports car would likely be the next in line for hybridization, said Muller, giving Porsche a direct competitor to the BMW i8. It wouldn't be the first time Zuffenhausen would slot a hybrid powertrain into the iconic rear-engined coupe, having previously raced the 911 GT3 R Hybrid (pictured above), but it would be the first road-going version available to customers. "That is a technique which we at Porsche are very familiar with," Muller told AN, "so we can suppose that we could have plug-ins all over the model range, not only to save fuel but also to boost the performance of these cars." Currently the E-Hybrid versions of the Cayenne and Panamera which Porsche offers account for roughly 15 and 11 percent of their respective model lines' sales in the US, while the 918 Spyder, of course, is offered only as a hybrid. If the 911 hybrid gets the green light, that would leave only the Macan, Boxster and Cayman without the option of electric assist. Related Video:
