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.

Satisfaction with dealer service rises, Lexus and GMC are tops

During the economic downturn, many car dealerships counteracted their slowing income by focusing on things that would set them apart from competition - things like the quality of customer service they provide. When the economy picked up and more sales and service followed, many also first invested those funds back into the business, improving their dealership facilities and service centers.
It looks like those investments are paying off, as J.D. Power and Associates' latest Customer Service Index Study shows that overall consumer satisfaction with dealer service has increased to 797 (on a 1,000-point scale), up from 787 in 2012 and 29 points higher than the score in 2011. The study also finds that people are more satisfied with the service they get at dealerships compared to independent service providers, despite the much higher average out-of-pocket cost per visit ($118 vs. $44).
Note, however, that this study only looks at how people are treated by a dealer's service department during the first three years of ownership (the survey is based on responses from 91,000 owners and lessees of 2008 to 2012 model year vehicles), so we're talking about the experience had when bringing a car in for repair or maintenance work, most likely under warranty. In fact, maintenance work is increasing in share and accounted for 77 percent of service visits (up from 72 percent in 2012 and 63 percent in 2011). This helps explain why customer satisfaction has also risen, since a properly maintained car is one that's less likely to require a dealer visit for an unexpected repair.

GM considering new powertrain options for large SUVs

Aside from the new General Motors offerings, there's not a whole lot of action going on in the fullsize SUV segment. That doesn't seem to be stopping GM from pushing the envelope in the market as Automotive News is reporting that the automaker is looking to introduce some new powertrain options into the Chevy Tahoe (and Suburban), GMC Yukon (and Yukon XL) and the Cadillac Escalade - all have been redesigned for the 2015 model year.
Now, we already know that GM and Ford are collaborating on nine- and ten-speed transmissions for a broad range of applications (including the big SUVs), but this new report says that GM is also considering other options as a way to one-up the competition and, of course, to optimize fuel economy. AN quotes Jeff Luke, executive chief engineer for GM trucks, as saying that "interesting powertrain technologies" are coming including a return of a hybrid SUV and possibly even a diesel engine. Although it sounds like the latter could come down to how customers respond to the 2014 Jeep Grand Cherokee EcoDiesel.
