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.
If you have about five minutes and you can't get enough information about the new 'Vette, then check out the videos posted below.

2014 Chevrolet Cruze TD fires up its new diesel motor

Ever since General Motors confirmed plans to produce a diesel-powered Cruze back in 2011, we've been eagerly awaiting its arrival. And as part of the 2013 Chicago Auto Show, Chevrolet has pulled back the cover on its oil-burning compact sedan, set to go on sale in the near future with a starting price of $25,695, not including $810 for destination.
The heart and soul of the Cruze TD (that's its official name) is a 2.0-liter turbo-diesel inline four-cylinder engine rated at 148 horsepower and 258 pound-feet of torque, mated solely to a six-speed automatic transmission. The engine also has an overboost function that will increase torque to 280 lb-ft for up to ten seconds. The full brace of official specs haven't been released, but GM tells us that highway fuel economy will come in at 42 miles per gallon. If that number sounds familiar, it's because the Volkswagen Jetta TDI has the exact same rating. Unlike the Jetta, however, the Cruze TD can run on B20 biodiesel, where as the Volkswagen can only accept B5.
Model-specific changes to this 2014 Cruze TD include an aero kit and unique 17-inch alloy wheels. Inside, there's a full leather interior, and Chevrolet will provide two years of complimentary scheduled maintenance, not to mention a 100,000-mile powertrain warranty.

GM cutting back on powertrain warranty citing lack of interest

Generally, when a manufacturer offers a long, high-mileage warranty, it's a sign that it stands behind its products. On top of that, it's generally a selling point for consumers, who can rest easy knowing that any catastrophic failures will be picked up by the manufacturer. Considering those facts, it does seem rather strange that General Motors is slashing the mileage warranty on model year 2016 vehicles from Chevrolet and GMC. Instead of offering consumers a 100,000-mile warranty, GM will now only offer a powertrain warranty up to 60,000 miles. The five-year warranty period, though, remains unchanged. GM will also cut the number of free services being offered to Chevy and GMC owners, as well as Buick drivers, from four to two. "Through research, we have determined that when purchasing a new vehicle, included maintenance and warranty rank low on the list of reasons why consumers consider a particular brand over another," explained a memo sent to dealers by Chevrolet VP Brian Sweeney and his GMC counterpart, Duncan Aldred, and obtained by Automotive News. "As a result, we have benchmarked our competitors, reviewed our current offerings and have concluded the following modifications to align closely with our customers' needs and expectations." While the move might seem odd, Sweeney and Aldred are right – according to Automotive News, Ford, Honda and Toyota each offer a five-year, 60,000-mile powertrain warranty. As for what the money saved by trimming the powertrain warranty will go towards, a GM spokesperson simply told AN that the company will "reinvest the savings we will realize into other retail programs," some of which have been requested by consumers. What are your thoughts? Would a 40,000-mile reduction in a new vehicle's powertrain really turn you off from buying one? Even if it matched its competitors?
