GM pushing back on proposed pickup and SUV brake recall [w/poll]

Through the first six months of 2014, General Motors has recalled 29 million cars and trucks in 54 different actions. If your author's notoriously sketchy math is correct, that'd work out to one recall every 3.5 days (as of this writing). GM is actively fighting to make sure there isn't a 55th recall, though.
Safety critics, including perennial nemesis Clarence Ditlow of the Center for Auto Safety, are calling on GM to recall a further six million pickup trucks and SUVs in northerly climes due to corroding brake lines caused by the use of road salt. There is a catch, here, though ­- the vehicles in question are over 10 years old, and include the 1999 to 2003 Chevrolet Silverado, Suburban and GMC Sierra, as well as the 2000 to 2003 Tahoe and Yukon (shown above).
GM issued the following statement on the matter, obtained by CNN Money:

2014 GMC Sierra 4.3L V6 to offer segment-best 305 LB-FT

General Motors has released more information on the 4.3-liter V6 available in the 2014 GMC Sierra. The engine will serve up 285 horsepower and 305 pound-feet of torque, with a six-speed automatic transmission, and giving the V6 Sierra a maximum tow rating of 7,200 pounds in regular cab, short bed four-wheel drive configuration. GM claims that figure is 500 pounds more than the equivalent Ford F-150 equipped with a 3.7-liter V6, and 700 pounds more than the Ram 1500 with its 3.6-liter V6. Buyers can expect to see the 2014 GMC Sierra with the 4.3-liter engine start at $25,085 including destination.
While the engine does deliver more torque than either of its main competitors, it falls short on the horsepower front. The 3.7-liter V6 in the F-150 develops 302 hp while the 3.6-liter V6 in the Ram 1500 yields 305 hp. GM says fuel economy estimates for its newest entry will land later this year.

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.
