GM tinkering with Silverado, Sierra model mix amidst strong early sales

Variety, as they say, is the spice of life. That's a lesson that is currently being taught to General Motors, because despite a strong showing from its 2014 Chevrolet Silverado and GMC Sierra, the General's pickup sales still can't best those of cross-town rival Ford.
With 59,163 trucks moved, GM fell just over 1,000 units short of toppling Ford, and one of the main reasons for that, according to GM's chief sales analyst, was due to a lack of variety in the engines and body styles available on dealer lots. "We are still over-weighted toward crew-cab V8 trucks. Our light-duty mix will moderate over time as our launch progresses," said Kurt McNeil.
Loading dealers with the popular combination of the 5.3-liter V8 and the four-door, Crew Cab body style was intentional during the truck's launch, but as supplies of leftover 2013 models, which are being sold at heavy incentives, are beginning to wane, both budget-conscious and high-dollar buyers are looking elsewhere instead of at the volume model pickups.

More Corvette Stingray Factoids: Vanishing panel gaps and 26-mpg LT1

During January's Detroit Auto Show, we managed a longer than expected wandering tag-team interview with C7 Corvette chief engineering exec Tadge Juechter (pictured above), and LT1 engine boss Jordan Lee (pictured below). They are, quite honestly, two of the very nicest bigshot lads to ever walk the engineering corridors of an American manufacturer. Both are enthralled by what they're doing for a day job. So are we.
We've followed the pre-sale anticipation for the Chevrolet C7 Corvette Stingray like an Oreck vacuum yanking every speck of dirt from a well-trampled carpet. Everything is reportable and contains a grain of further knowledge about this dramatically important and cheered-for car, as it continues to be pressured into representing all that is superior about the American dream. The Corvette wears one heavy cloak.
So, most of what was talked about has been expertly reported already right here on Autoblog. But, looking through our notes again, both Jeuchter and Lee added facts to the buzzing mix.

Why does the Corvette Stingray have so many vents? Here's why

Just looking at the new 2014 Chevrolet Corvette Stingray, it's not hard to see that the car's design was created with aerodynamics at the forefront, but Chevrolet designers point out exactly what went into designing the iconic coupe in a pair of recently released videos. The videos show the Corvette going through early design phases, including clay models and wind tunnel tests, as well as talking to the car's chief engineer, Tadge Juechter.
Both videos help explain various aspects of the C7 Corvette, but it's the aero tuning of the car that is most interesting. This includes extra attention paid to the lower air dam and vented hood to help reduce drag and lift, while the rear quarter inlets are for differential and transmission cooling. Juechter said that some of these aero-tuned elements were inspired from GM's involvement in racing.
