Lutz dishes dirt on GM in latest Autoline Detroit

Bob Lutz sits down for Autoline Detroit - Click above to watch video after the jump
Autoline Detroit recently played host to Bob Lutz, and, as is always the case, the former General Motors vice chairman dished out some great commentary. Lutz was promoting his new book Car Guys vs. Bean Counters: The Battle for the Soul of American Business, and talk quickly turned to his role as it related to product development and high-level decision making at GM. While on the topic of brand management, Lutz revealed a few rather interesting tidbits about his former employer:
All Chevrolet vehicles were required to have five-spoke aluminum wheels and a chrome band up front, as part of the Bowtie brand's overall image.

These cars are headed to the Great Crusher In The Sky

It happens every year. We bid adieu to some cars and trucks that will be missed, and say good riddance to others wondering how they stayed around so long. Whether they're being killed off for slow sales or due to a new product coming along to replace them, the list of vehicles being discontinued after 2012 is surprisingly long and diverse.
CNN Money has compiled a list of departing vehicles, to which we've added a few more of our own. In the slow sales column, cars like the Lexus HS 250h, Mercedes-Benz R-Class and the full Maybach lineup appear, while the Ford Escape Hybrid, Mazda CX-7 and Hyundai Veracruz are all having their gaps filled with more modern and more fuel-efficient alternatives. Obvious exceptions to the rule include models that still sell in decent numbers like the Jeep Liberty and the Chrysler Town & Country (which will eventually be replaced by a crossover-like vehicle).

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.
