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 Classic launching branded motor oil for air-cooled boxer engines

It's hard not to love the look of a classic Porsche. Whether it's the upside-down bathtub styling of the 356 or the gradual evolution of the 911, there is a little beauty in all of them. However, the older they get, the more that needs repaired to keep them on the road. Porsche Classic is helping out, though, by introducing its own brand of motor oil for the demands of the company's vintage, air-cooled engines.
Developed at the Porsche Development Centre in Weissach, Germany, Porsche Classic Motoroil comes in two weights - 20W-50 for the 356, 914 and 911 models up to the 2.7-liter G-Model and 10W-60 for 3.0-liters-and-up engines through the 993-chassis 911. The company claims that the air-cooled engines have different heat demands than traditional, water-cooled units, and this oil is made to meet those requirements.
According to Porsche, modern, synthetic oils are sometimes too effective when it comes to old engines. They are fantastic at sopping up debris, but those deposits are often holding archaic seals together. Suddenly removing them can cause leaks. The new oil is specifically designed to work with the old-fashioned materials found in its classics. The company also knows that most owners aren't driving their vintage cars everyday. So this formulation is more alkaline that normal to neutralize acids that they build up and corrode components.

Mercedes S63 AMG Coupe vs Porsche Panamera Turbo S in unusual lux showdown

We'll admit it, we're really looking forward to more time with the Mercedes-Benz S-Class Coupe. Compared to other high-dollar luxury coupes - we're looking at you Bentley Continental GT - it's more stylish, easily more affordable, and since it's a Mercedes, lacks the sense of fragility that comes with a more exotic name plate.
Auto Express has taken a whack at reviewing the new two-door S-Class, and for some reason, the British mag is comparing it with a Porsche Panamera. Now, while comparing the looks of an S-Class Coupe and a Panamera is a bit like holding a beauty contest between Kate Upton and Medusa, this isn't as bizarre a pair as you might think, particularly when you opt for the high-dollar S63 AMG Coupe and the Panamera Turbo S.
The two offer similar power outputs from their force-induced V8s - 577 horsepower in the Benz and 570 horsepower in the Porsche - and are even similar in terms of interior and exterior dimensions. The S-Class actually has an extra inch between the axles and is 1.2 inches longer overall (it's also about 300 pounds heavier). In the cabin, the S-Class also has a tiny bit more rear legroom, with 33.4 inches to the Panamera's 33.3.
