It's time for Corvette to attack Porsche

For most of its existence, Porsche was a smug little sports car company with a fairly limited lineup and small but steady sales. Any time the company strayed from its air-cooled, rear engine formula, the purists would turn their noses. The 944? The 948? "Not a proper Porsche," they'd sniff. And then came the greatest sin of them all: the Cayenne. To the purists, this was treason. Porsche making an SUV? Horrors! Of course, you all know how it turned out. Porsche grew to be a profit-generating juggernaut within the Volkswagen Group. And since one SUV wasn't enough they added another, the Macan. By the end of the decade Porsche will have quadrupled its global sales. You have to wonder what else it has up its sleeve. Couldn't this be a lesson for General Motors? It has a terrific sports car brand in Corvette. In fact, it's arguably the most iconic brand within GM's full-line portfolio. But for its entire existence that brand has been locked up within Chevrolet. Maybe it's time for GM to treat Corvette as a stand-alone company. Maybe it's time for GM to unlock that brand and treat Corvette as a stand-alone company. A Corvette SUV could be a killer first step. Since Porsche only makes two SUVs, maybe Corvette could make three. Small, medium, and large. And just as Porsche has the Panamera, an executive sedan from team Corvette could become an instant "gotta-have" for the yacht-buying jet set. Of course, the Corvette purists will cringe. And the biggest hue and cry will come from Chevrolet's US dealers. That's why the best place to launch the new Corvette brand would be far away from those franchisees: in China. Chinese consumers have no pre-conceived ideas that 'Vettes can only be sold in Chevy stores. And Chinese enthusiasts very much admire Corvette's historic pedigree. You've no doubt read about how Chinese authorities are cracking down on conspicuous consumption. That makes the timing even better. Corvette's selling point has always been that it is an amazing bargain for the performance you get. What a perfect way to undercut Porsche. In fact, pairing the Corvette brand with Cadillac in China could be just the shot in the arm that Cadillac's Chinese dealers need. Despite having very competitive cars, Cadillac lags far behind Audi, Mercedes, and BMW. What Cadillac dealers need is a lot more showroom traffic. And a jaw dropping lineup of Corvette-branded vehicles could bring in throngs of buyers.

Conquest and controversy conclude the 2014 Rolex 24 at Daytona [spoilers]

If you don't wish to know who won the 2014 Rolex 24 at Daytona, you should avert your eyes right now. We'll even give you a double-space to skedaddle...
For those of you still with us, the first race in the United SportsCar Championship (USCC) is done, but the discussions about it certainly won't end for a while. Daytona Prototypes claimed the first four overall places, the top spot taken by the No. 5 Action Express Coyote-Chevrolet Corvette DP driven by Joao Barbosa, Christian Fittipaldi, Sebastien Bourdain and Burt Friselle. The 16th and final caution of the race bunched the field up for an eight-minute sprint to the flag, so the first place getter finished just 1.4 seconds ahead of the No. 10 Wayne Taylor Racing Dallara-Chevrolet Corvette DP driven by Max Angelelli. Third place went to Brian Friselle in the No. 9 Action Express Chevrolet Corvette DP, 20 seconds down. Chevrolet power hasn't taken the overall win since 2003, eleven years later it scores a one-two-three-four. The No. 6 Muscle Milk/Pickett Racing ORECA-Nissan 03 scored fifth place, the top LMP2 finisher.
The Prototype Challenge class win went to the No. 54 CORE Autosport team of Colin Braun, Jon Bennett, Mark Wilkins and James Gue.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.
