2017 GMC Acadia loses 700 pounds, gains everywhere else

Ladies and gentlemen, welcome to Acadia. The 2017 version of the three-row GMC crossover has all kinds of newness. The 2017 Acadia has lost 700 pounds compared to its predecessor thanks to high-strength steels allowing redesigned parts, and the fact that it overall, the vehicle is actually smaller. Length is reduced by 7.2 inches on a wheelbase diminished by 6.4 inches, it is 3.5 inches narrower and sits 3.9 inches lower. The 2016 Acadia was 4,656 pounds, the 2017 is 3,956 pounds. GMC says it will still swallow people, but not as many: the eight-passenger option didn't make the transition, potential three-row trims permitting five-, six-, and seven-passenger configurations. While you lose space, you gain convenience with a split-folding second row featuring tilt-and-slide for both sections. The third-row seats fold flat into the cargo floor, and if the second row is folded as well, cargo capacity improves over the 2016 Acadia, 79 cubic feet compared to 70 cu-ft. A new 2.5-liter four-cylinder brings a second engine option to the spec sheet, returning an estimated 22 city miles per gallon and 28 highway mpg with the help of stop/start tech on front-wheel-drive trims. The new 3.6-liter V6 gets around 310 horsepower, a power bump of about 19 hp, and an estimated 25 highway mpg in front-wheel-drive guise. Towing capacity for that V6 goes down, though, from 5,200 on the current Acadia to an estimated 4,000 pounds. The optional Tow Vision Trailering system will make that pulling easier. Both engines are hooked to a six-speed automatic. Now we can get to its looks. Trademarks like the square, flared wheel arches, dark D-pillars, and wraparound rear side windows made the transition, everything else is new. While weight has gone down, safety's gone way up with internal changes like the splayed chassis members to confront the small-offset test. New active safety upgrades run from from three kinds of automatic braking systems to surround vision cameras, automatic high beam control, a safety alert seat, and a following distance indicator. Buyers can choose from a front-wheel drive, all-wheel drive, or All Terrain model, each with its own electronic drive selector modes. The Normal, Sport, and Trailer/Tow modes are common to the trio. The FWD gets a Snow mode, the AWD adds adaptive 4x4 and Off Road modes; on the AWD, the 2x4 mode disconnects the rear axle from the drivetrain.

GM recalling 686k Lambda-platform models for hatch repair

General Motors is recalling 686,287 units of its Lambda platform crossovers. On models equipped with a power rear hatch the system can potentially fail. This campaign includes the 2008-2012 Buick Enclave, 2009-2012 Chevrolet Traverse, 2007-2012 GMC Acadia, and 2007-2010 Saturn Outlook. According to GM's documents to the National Highway Traffic Safety Administration (as a PDF), dirt can get into a portion of the strut that holds up the hatch and cause the part to prematurely fail. There's a redundancy in place called the Prop Rod Recovery system that's designed to shut the liftgate if there's a malfunction. However, if the breakdown happens too quickly after the hatch is opened the prop rod might not work the way it's supposed to. If someone were in the way of the falling liftgate, they could be hurt. For the repair, dealers will update the software for the power liftgate actuator motor control unit to prevent the hatch from closing so quickly. They'll also check the operation of the system afterward.

The affected vehicles, equipped with the power liftgate option, have gas struts that hold the power liftgate up when open. These struts may prematurely wear and the open liftgate may suddenly fall. CONSEQUENCE: If the open liftgate unexpectedly falls, it may strike a person, increasing their risk of injury. REMEDY: GM will notify owners, and dealers will update the software for the power liftgate actuator motor control unit so that the motor will prevent the rapid closing of the lift gate, free of charge. The manufacturer has not yet provided a notification schedule.

2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.
