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.

GM reportedly developing 2.5-liter turbo four-cylinder

General Motors is allocating a massive amount of resources to developing electric technology, but it's not forgetting about the gasoline-powered cars that make up the bulk of its sales. It's reportedly designing a new 2.5-liter turbocharged four-cylinder engine based on its 2.7. Citing "sources familiar with the matter," enthusiast website GM Authority wrote that the 2.5-liter four is "in [the] final stages of development," meaning it should be announced sooner rather than later (assuming the report is accurate). Technical details are few and far between as of writing. The publication learned that the 2.5 will be part of the Cylinder Set Strategy (CSS) family of engines and that it will be mechanically related to the 2.7-liter currently found in the Chevrolet Silverado 1500, among several other models. It will feature dual overhead camshafts. It's too early to tell which models the 2.5-liter four-cylinder will end up in, or how much power it will generate. The output will likely depend on the application. For context, the 2.7 delivers 310 horsepower at 5,600 rpm and 348 pound-feet of torque between 1,500 and 4,000 rpm in the Silverado. In the smaller Colorado, it provides anywhere between 237 and 310 horsepower depending on the trim level selected. While this is pure speculation, our crystal ball tells us the engine will end up powering crossovers. It's an easy deduction to make. We can't imagine it will be offered in the Silverado, and seeing it in the Colorado is unlikely because its entry-level engine develops 237 horsepower; there's likely not much of a market for a midsize truck with 200 or so horsepower. Putting it in the Corvette wouldn't make sense and the Camaro has nearly reached the end of its life cycle without a successor planned. This leaves us with Chevrolet's range of crossovers, like the Equinox, as well as their GMC-, Buick-, and Cadillac-branded counterparts. We're not discounting the possibility that the cars set to receive the 2.5 haven't been unveiled, but those are likely crossovers, too; the odds of seeing another big Chevy sedan are very, very low. General Motors hasn't commented on the report, and it hasn't publicly announced plans to expand its CSS family of engines. If the report is accurate, we should learn more about the new turbocharged, 2.5-liter four-cylinder engine in the not-too-distant future.
