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 inspecting 2,500 Euro-spec Macans for damaged brake boosters

Porsche is investigating a potential brake issue with 2,500 of its new Macan CUVs. The inspection focuses on the state of the brake systems following tests that discovered the brake boosters may have been damaged during assembly.
Porsche has pointed out that, despite the concern, the affected Macans still meet safety regulations. The issue is predominantly found in European-spec Macans, which according to Porsche, have been delivered to consumers. Owners of affected vehicles in Europe will be notified and asked to come in for a brief, no-cost inspection.
American consumers, though, have no reason to worry. We reached out to Porsche Cars North America, who confirmed that the vehicles in question were assembled before US-spec cars were screwed together.

Ruf RGT 4.2 offers 518 hp of naturally aspirated power

Ruf has a reputation for building some fast interpretations of the Porsche 911, and the company's latest RGT 4.2 at the Geneva Motor Show provides an interesting point of comparison compared to the new GT3 RS that's debuting there. In terms of pure power, the Ruf wins out. The company crafts a flat six with 4.2-liters of displacement making 518 horsepower and 369 pound-feet of torque with a top speed of 200 miles per hour. In contrast, the latest GT3 RS gets 500 ponies and 338 lb-ft of twist from its direct-injected 4.0-liter mill. Depending on your desires, the RGT 4.2 might have the preferred gearbox too with its six-speed manual versus the Porsche's PDK. Styling is also going to come down to personal tastes between these two. The RGT 4.2 has an almost old-school racing look with its bolted-on fender flares, five-spoke wheels, thick carbon fiber rear wing and lower front air dam. Inside, there's also an integrated roll cage. The RS, on the contrary, appears thoroughly modern with its big fender intakes at the back, slashes just behind the front wheels, CFRP hood and magnesium roof. Check out Ruf's naturally aspirated monster on the Geneva show floor in the gallery, above. The RGT 4.2 maintains a long tradition of Ruf supercars with its outrageous driving performance. Unveiled in 2000, the first RGT was characterised by its powerful, torquey normally-aspirated flat-six engine. With a significantly reduced all-up weight and sports-oriented suspension system, the RGT was an extremely impressive driving machine.Now, in 2015, the RGT remains true its original concept, though its external appearance is clearly more athletic. The wheel arches are more bulbous and the front facade presents huge round air intakes for more effective cooling. The chassis is reinforced by RUF's hallmark Integrated Roll Cage (IRC). Propulsion is provided by its virile 4.2-litre six-cylinder, normally-aspirated engine, developing 525bhp and 500Nm of torque, featuring dry sump lubrication with external oil tank.
