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?"

2017 Porsche 911 Carrera First Drive [w/video]

The second seismic shift in the history of the Porsche 911 is happening as you read this. The first came in the late 1990s, when air cooling was thrown out and a more modern, water-cooled setup was put in place. People freaked out, and prices of air-cooled 911s are now skyrocketing. But I'll argue that this second major change is an even bigger deal: The free-breathing, naturally aspirated engine is gone, in its place a smaller, more powerful, turbocharged lump. But there's no need to panic. Purists be damned; "no replacement for displacement" shouters be silenced. This forced-induction heart beats beautifully in the 911's rump. I'm behind the wheel of a 2017 911 Carrera S coupe, stopped at the base of a winding mountain road on Tenerife, the largest of the Spanish-owned Canary Islands off the northwest coast of Africa. A nearly identical 911 is ahead of me, piloted by one of Porsche's test drivers. The road is closed. Hired spotters watch the corners. I'm about to run up the mountain at full charge, Porsche's expert leading the way. This forced-induction heart beats beautifully in the 911's rump. Behind me is the new engine: a 3.0-liter, twin-turbocharged flat-six. At idle, it still has that unmistakably Porsche, horizontally opposed hum. I've got 420 horsepower and 368 pound-feet of torque to work with, increases of 20 hp and 43 lb-ft compared to the old 3.8-liter, naturally aspirated six. If I launch it, I'll hit 60 miles per hour in under four seconds. Power is routed through the Porsche Doppelkupplung transmission – the best dual-clutch tranny in the business – and the fat, 305-section Pirelli PZero tires out back get all that thrust to the ground. There's a strong engine noise, complemented by the sound of the turbos sucking in air via the intakes just below the rear window. And then there's the exhaust. The standard Carrera comes with two large outlets and the Carrera S replaces those with quad pipes. But I've got the optional sport exhaust, not pictured on the car you see here, with two round outlets moved toward the center of the 911's hiney. Not only do they look way cooler, they're a treat for the ears. The Spanish may have decided to tunnel through many of Tenerife's mountainsides, but the pleasure of punching the throttle and letting the exhaust sing easily makes up for any loss of scenic views. The Carrera S' full 368 lb-ft is available right from 1,700 rpm, and there's no lag prior to arrival.

2016 Porsche 911 GT3 RS prowls into Geneva with biggest NA engine in the 911 range [w/video]

We've been waiting for the debut of this road-going and race-ready Porsche 911 GT3 RS for quite some time now. As is typical for high-profile sports machines, the new 911 has been foreshadowed with spy shots and information leaks aplenty, all pointing to this grand day at Geneva. Here she is. Just a glance at the duct-sliced bodywork and massive rear wing will tell you that this Porsche means business, but let's look at its bona fides. The heart of the matter, under that short rear deck, is the largest-displacement and most powerful naturally aspirated engine in the 911 family, with 500 horsepower and 338 pound-feet of torque developed by the 4.0-liter flat-six. That hoss of an engine is mated to a newly developed version of Porsche's PDK dual-clutch gearbox – with functions such as "paddle neutral" that effectively works like depressing the clutch on a standard manual, and a Pit Speed button for on the track. Working in concert, engine and trans allow the GT3 RS to sprint to 60 miles per hour in 3.1 seconds, hit a quarter mile in 11.2, and lap the Nurburgring Nordschleife in just seven minutes, 20 seconds. (That 'Ring time makes it the fastest current 911 around the benchmark course, and five seconds faster than the current 911 GT3 – so quick.) Weight has been saved via exotic materials; the car sports a magnesium roof and carbon fiber for the trunk and engine lids. Overall the RS is 22 pounds lighter than the GT3, but also boasts a lower center of gravity. As we said at the top, there's a wide, low and aggressive body kit on the GT3 RS, all engineered with racing performance in mind. That huge rear wing is balanced in the front by a deep chin spoiler, and the front wheel arches have been punctuated with vents that help to increase downforce on the front axle. The roll cage is the most obvious interior modification to let one know that this is a racing tool, but Porsche has also slathered the space in Alcantara and installed carbon-fiber bucket seats (based on those found in the 918 Spyder) to drive the point home. The cost of such racing glory will be steep at $175,900 plus a $995 destination charge, but not out of the scope of the current ask for the 911 range, when you consider that a Turbo S runs over $180k. Look for 911 GT3 RS deliveries to start in July of this year in the US, and for track days to be more competitive for the addition.
