2017 Chevy Corvette Grand Sport spotters guide

The 2017 Corvette Grand Sport is a mix of regular Stingray and steroidal Z06. Unveiled at the 2016 Geneva Motor Show, this tweener 'Vette will go on sale this summer. If you need a refresher, click here for the details and official press release. We sat down with Chief Engineer Tadge Juecter in Switzerland to explain the differences between the Grand Sport and the rest of the Corvette lineup. <p>Your browser does not support iframes.</p> Stingray Hood The Grand Sport comes with the LT1 V8 (and 460 horsepower) instead of the supercharged LT4 in the Z06. That means the Grand Sport gets the lower Stingray hood, absent the power bulge. The Grand Sport also weighs less than the Z06. As such, the Grand Sport's springs and anti-roll bars are different to accommodate the lighter nose. "Mainly it's the weight distribution that changes," explains Juecter, "It's a custom tune around the obvious standard components." Grand Sport Wheels, Z06 Brakes In the sixth-generation Corvette, the Grand Sport came with a Z06-style body but kept the standard Vette's steel structure. With every version of the C7 built on an aluminum backbone, the Grand Sport has almost the same structure as the Z06. That means the Grand Sport can handle all the track-ready goodness like Z06 brakes and the optional Z07 package that adds carbon-ceramic disks and Michelin Pilot Sport 2 Cup tires. Except the Grand Sport comes without the max-downforce add-ons of the Z07-packaged Z06, because it doesn't need them. What you can't get on the Z06, though, is the unique Grand Sport wheel design, which comes in five different finishes. Stingray Brake Lights, Interior The dead giveaway for the Grand Sport is the hash marks on the front fenders which come in six different colors. Another way to spot the Grand Sport is the taillights, which use the Stingray's red lenses instead of the blacked-out Z06's lights. Z06 body plus taillights equals Grand Sport. Got that? The Grand Sport also comes with body-color rear fender vents, which are black on the Z06. And the Grand Sport's interior is based on the Stingray except the Collector Edition, which has unique blue accents.

GM re-recalls 11k SUVs

General Motors is recalling a bunch of previously recalled SUVs because, well, they still aren't quite fixed. The latest repairs are necessary on 10,974 SUVs in North America, including 9,932 in only the US. Affected models include the 2006-2007 Buick Rainier, Chevrolet Trailblazer, and GMC Envoy; plus the 2006 Trailblazer EXT and Envoy XL. While not listed by NHTSA, a statement by GM to Autoblog says the 2006-2007 Saab 9-7X and Isuzu Ascender are also affected. In these SUVs, it's possible that liquid could get into the driver's door master power window switch module and cause a short circuit. This could potentially lead to a fire, and owners are urged to park the vehicles outside until repaired. GM has been trying to fix this issue for years. It started as an investigation into fires, and that led to a recall for about 250,000 vehicles in cold-weather states. A nationwide campaign came in 2013 for 193,000 of them in the US. Last year, the automaker decided to replace the whole module as a repair. However in a recent investigation of these recalls, GM discovered that this latest group of SUVs never received the new part. According to documents submitted to NHTSA (as a PDF), "Some dealers incorrectly used the labor code associated with module replacement when, instead of replacing the module, they only added a protective coating to the module." To fix things this time, the models finally get the correct component. Related Video: GM Statement General Motors is recalling 9,932 older midsize SUVs in the U.S. because they were mistakenly excluded from an earlier recall. Certain 2006 Chevrolet TrailBlazer EXT and GMC Envoy XL, and 2006-2007 TrailBlazer, Envoy, Buick Rainier, Saab 9-7X and Isuzu Ascender vehicles may continue to have a condition in which the printed circuit board inside the driver's door may corrode and short if exposed to certain fluids such as melted snow containing road salt. GM is aware of four fires but no crashes, injuries or fatalities associated with the expanded recall. The total number of vehicles being recalled, including Canada, Mexico and exports is 10.974. Customers are urged to park these vehicles outside until repairs have been made. GM reported this recall to the NHTSA on September 23.

Chevy Corvette is latest car breached by hackers

UPDATE: This story has been updated with comment from General Motors. In the latest car-hacking exploit in a summer full of them, researchers from the University of California-San Diego say they've found a way to manipulate braking in a 2013 Chevrolet Corvette. The vulnerabilities may not be limited to that model. Cyber-security researchers breached the car's security systems via a device they had plugged into the Corvette's OBD-II port, and through that connection, they sent messages that could turn windshield wipers on and off and tamper with the brakes as the car drove at low speeds. It's the latest in a series of car hacks that involve access to critical systems obtained via the OBD-II port, where drivers can plug in devices that provide anything from diagnostic information for mechanics to driving information for insurance companies. Last November, cyber-security engineers from Argus Cyber Security remotely controlled vehicle functions in a car that had a OBD-II dongle called a Zubie installed. In January, researchers from Digital Bond Labs found security holes in an information-tracking dongle popular with more than 2 million Progressive Insurance customers. Those came before prominent hacks unveiled in recent weeks, in which researchers remotely commandeered control of a Jeep Cherokee and, separately, showcased problems with GM's OnStar infotainment system. Regarding the dongles that plug into the OBD-II ports, Stefan Savage, a Cal-San Diego professor involved in the research, tells WIRED that, "we acquired some of these things, reverse-engineered them, and along the way, found that they had a whole bunch of security deficiencies." Savage and others unveiled the latest study at the Usenix security conference Tuesday. In a video of their exploit entitled "Fast and Vulnerable," they show how they sent SMS messages from a smartphone to the dongle plugged into the car's OBD-II port. From there, their messages accessed the CAN bus, a network on the car that connects individual electronic control units, which control dozens of vehicle functions. As they send the commands to brake the car, the driver of the Corvette notes "the pedal doesn't react to any pressure." General Motors issued a written response Wednesday, warning drivers to be careful with third-party devices they plug into their OBD-II ports.
