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.

IIHS gives good ratings to 4 of 8 midsize pickups in crash test

Versions of the Toyota Tacoma, Chevrolet Colorado and GMC Canyon Crew Cab earned top ratings in a new crash test of midsize pickup trucks from the Insurance Institute for Highway Safety, while two versions of the Nissan Frontier earned marginal ratings. But the organization gave poor marks to all eight pickups tested for their dim headlights. Overall, four of the eight pickups evaluated earned good ratings for protecting occupants in all five crash test categories — the Tacoma double cab along with crew cab versions of the Colorado, Canyon and Tacoma. But the poor headlights and lack of an automatic emergency braking system blocked any of the pickups from qualifying for the IIHS's Top Safety Pick awards. The study looked at two pickup body styles using 2017 models: crew cabs, which have four full doors and two full rows of seating, and extended cabs, which have two full front doors, two smaller rear doors and compact second-row seats. It subjected each to five tests, and it evaluated the performance of front crash prevention systems and headlights. The Toyota Tacoma crew cab was the only pickup in that class that earned a good rating for structure in the small overlap test, which replicates what happens when a vehicle clips a tree, pole or another vehicle that has crossed the center line. The model's Access Cab extended-cab version was rated similarly, though its structure was rated acceptable. "This group of small pickups performed better in the small overlap front test than many of their larger pickup cousins," says David Zuby, the Institute's executive vice president and chief research officer. "The exception was the Nissan Frontier, which hasn't had a structural redesign since the 2005 model year." The extended-cab versions of the Chevy Colorado and GMC Canyon earned acceptable ratings, while both the Nissan Frontier king-cab and crew-cab models were rated marginal. Toyota says its 2018 Tacoma will feature upgraded headlights and a standard autobraking system that can detect pedestrians. "Headlights are basic but vital safety equipment. Drivers shouldn't have to give up the ability to see the road at night when they choose a small pickup," Zuby said.

Detroit 3 to implement delayed unified towing standards for 2015

Car buyers have a responsibility to be well-informed consumers. That's not always a very simple task, but some guidelines are self-evident. If you live in a very snowy climate, you generally know a Ford Mustang or Chevrolet Camaro might not be as viable a vehicle choice as an all-wheel drive Explorer or Traverse, for example. If you want a fuel-efficient car, it's generally a good idea to know the difference between a diesel and a hybrid. But what if it's kind of tough to be an informed consumer? What if the information you need is more difficult to come by, or worse, based on different standards for each vehicle? Well, in that case, you might be a truck shopper. For years, customers of light-duty pickups have had to suffer through different ratings of towing capacities for each brand. For 2015 model year trucks, though, that will no longer be a problem. According to Automotive News, General Motors, Ford and Chrysler Group have announced that starting with next year's models, a common standard will be used to measure towing capacity. The Detroit Three will join Toyota, which adopted the Society of Automotive Engineers' so-called SAE J2807 standards way back in 2011. The standard was originally supposed to be in place for MY2013, but concerns that it would lower the overall stated capacity for trucks led Detroit automakers to pass. Ford originally passed, claiming it'd wait until its new F-150 was launched to adopt the new standards, leading GM and Ram to follow suit. Nissan, meanwhile, has said it will adopt the new standards as its vehicles are updated, meaning the company's next-generation Titan should adhere to the same tow ratings as its competitors. While the adoption of SAE J2807 will be helpful for light-duty customers, those interested in bigger trucks will still be left with differing standards. There is no sign of the new tow standards being adopted for the heavy-duty market.
