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.

NHTSA closes 4-year GM investigation, issues common sense advisory [w/video]

Since January 2011, the National Highway Traffic Safety Administration has been investigating a possible problem with corroding brake lines in General Motors' GMT800-platform models, like the Chevrolet Silverado and Suburban and GMC Sierra, in states with salt on their roads in the winter. However, as opposed to launching a full recall of millions of vehicles, the government is issuing a common-sense safety advisory to all drivers in snowy states to keep their vehicle's undercarriage clean. It even has a video explaining things. "Older-model vehicles, often driven in harsh conditions, are subject to corrosion over long periods of time, and we need owners to be vigilant about ensuring they, their passengers, and others on the roads are safe," said NHTSA Administrator Mark Rosekind in the announcement of the end of the investigation. The agency was clear in its report that "brake line corrosion seen in the GM vehicles was not unique," and the government "has not identified a defect that would initiate a recall order." Instead NHTSA is advising drivers, especially those of vehicles from before 2007, to wash their vehicle's undercarriage in the winter and spring to remove salt or other de-icing chemicals. It also recommends regular checks by a mechanic to make sure everything is in proper order. According to the investigation documents, for just the GMT800 platform models, NHTSA found 3,645 complaints of brake line corrosion, which included allegations of 107 crashes and 40 injuries. The issue was found to be more common in vehicles over 10 years old. GM has released a statement (embedded below) that the company "supports the consumer advisory from NHTSA urging regular maintenance and care of brake lines on older vehicles." NHTSA Closes Investigation into Brake-Line Failures NHTSA 13-15 Thursday, April 9, 2015 Agency issues safety advisory on preventing undercarriage corrosion WASHINGTON – The Department of Transportation's National Highway Traffic Safety Administration (NHTSA) today issued a Safety Advisory and consumer video encouraging owners of model year 2007 and older trucks, SUVs and passenger cars to inspect brake lines and thoroughly wash the underside of their vehicles to remove corrosive salt after the long winter in order to prevent brake-line failures that increase the risk of a crash.

GM cutting vehicle trim options to save money for electrification

Information continues to filter out about GM's plans based on comments the automaker made during its Capital Markets Day event in February. GM President Mark Reuss said the company's push to save money by rationalizing the number of build combinations will continue in 2020, carrying on the work done in 2019. As GM Authority covers, last year, the carmaker cut 3,500 components across model lines, a 12% drop in the number of parts it needed to stock in its plants. Reuss used the next-generation Chevolet Equinox and GMC Terrain as examples for more cost efficiencies, saying build possibilities — which include international markets and their options — will be cut by more than 50%, and use more shared parts. "We will reduce total trim levels on Equinox and Terrain from eight to six," Reuss said, "reduce engine variants from 11 to 5, reduce build combinations from more than 200 to less than 100 per program, and see significant cost savings of an already paid-for architecture that took the mass out, helping us self-fund electrification programs." GM will plow a large amount of the money it saves into its ambitious EV program. In 2017, the automaker said it intends to have 20 electric vehicles on the market by the end of 2023, some of which could be shared between brands. An automotive analyst at Seeking Alpha and a piece in Automobile attempted to put specifics to what we should expect. As Automobile points out, the first two EVs in the 20-car program are already on sale, being the Ariv Meld and Ariv Merge eBikes available in Belgium and The Netherlands. We've seen the Cruise Origin autonomous rideshare taxi, although we don't know when it will hit the road. The next three, which we should see in the metal shortly, are two Cadillac EVs and the GMC Hummer EV pickup. The Cadillac pair are expected to be sized like the XT4 and XT5, and along with the Hummer, should hit the market starting in late 2021.
