2017 Chevy Corvette Grand Sport brings American fury to Geneva

Power isn't everything – even when it comes to Corvettes. Sure, the mighty, 650-horsepower Z06 is a real peach, but there's a lot to be said for the base Stingray with its naturally aspirated LT1 V8, putting out 460 hp in top spec. That's still plenty of grunt. Now, put that engine in a lightweight, aerodynamic-focused Corvette with super-sticky tires, and you get the new Grand Sport – a naturally aspirated Stingray that can pull up to 1.2 Gs. GM says the new Grand Sport is nearly as quick around its Milford Proving Ground track as the previous-generation ZR1. Specific updates include sticky Michelin Pilot Super Sport summer tires – 285/30ZR19 up front and 335/25ZR20 at the rear. Huge Brembo brakes are fitted to slow things down with a quickness, new stabilizer bars and springs keep the car hunkered down, and a seven-speed manual and eight-speed automatic transmissions are available. Want an even more hardcore package? Option the Z07 pack, which adds carbon ceramic brakes and Pilot Sport 2 Cup tires. Both coupe and convertible versions will be available, and a Collector Edition will come later in the year, painted in Watkins Glen Gray with Tension Blue hash marks, satin black stripes, black wheels, and a blue full leather and suede interior. The 2017 Corvette Grand Sport debuts at this week's Geneva Motor Show, and will go on sale in the US this summer.

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.

New recall issued in 2019 Chevy Silverado and GMC Sierra brake software saga

General Motors (GM) has issued a new recall for select 2019 Chevy Silverado 1500 and GMC Sierra 1500 pickup trucks that aims to resolve a faulty fix for a previous recall. According to National Highway Traffic Safety Administration (NHTSA) campaign No. 20V055000, a software update for the Electronic Brake Control Module (EBCM) could cause the electronic brake assist to be disabled.  The NHTSA first launched a recall for 463,995 Silverados, Sierras, and Cadillac CT6es on December 12, 2019 due to a software issue in the electronic brake control module (EBCM) that could disable the electronic stability control (ESC) and anti-lock braking system (ABS). As a response and resolution to that recall, GM began to reprogram the software in affected vehicles. GM later learned that the fix was creating a different problem. The installed software had its own error that was disabling the electronic brake assist. If customers see “Service Brake Assist” or “Service ECS" diagnostic warnings, they should park the vehicle and have it towed to a dealership, GM warns. While GM was going through the process of testing, pinpointing the issue, determining action and working with the NHTSA, safety experts have criticized Chevrolet and GMC for not reacting promptly and appropriately.  According to the recall, 148,055 are now affected, all of which do not meet the standards of Federal Motor Vehicle Safety Standard (FMVSS) number 126, "Electronic Stability Control" and 135, "Light Vehicle Brake Systems." To fix the braking issue, GM will once again reprogram the software. GM began notifying owners of the recall on February 10, 2020. Related Video:
