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.

Chevrolet SS previewed by Holden VF Commodore SS V show car

It won't be long before we see the official, production-ready Chevrolet SS sedan (hint: it will be revealed this weekend). And to tide us over until all of the official details are released about the US-spec version, we have this: the Holden VF Commodore SS V show car, a performance-oriented brother to the Calais V that debuted earlier in the week.
What we really want to know about the SS V is what lies underhood, but General Motors' Australian arm is keeping that under wraps until the Chevy model breaks cover this weekend. Nevertheless, it's obvious that the SS V will be a serious performer, with all sorts of aggressive cues driving that home on the car's exterior. Take a look at those 20-inch billet aluminum wheels that hide big Brembo brake calipers up front, the sculpted hood and front fascia, the wide air intakes with LED running lights and the quad exhaust pipes out back. It's like the Pontiac G8 GXP never even left us.
Inside, there's a sporty-looking interior with aluminum accents that mix in with black leather and suede surfaces, all tied together in the middle with an eight-inch MyLink touchscreen infotainment system. It looks great, and again, while we don't know anything regarding powertrain details, it makes us oh-so happy to see a manual shifter smack dab in the middle of the center console.

2015 Chevrolet Cruze spied on its home turf

The next Chevrolet Cruze isn't set to go into production for about another year, and we're just now seeing prototypes of the new compact running around here in the States. Not much more has been revealed since we saw the car blasting through the snow in Europe, but we can still clearly see new design elements like the larger grille, slimmer headlamps and redesigned taillamps.
Our spy photographers worked up a composite image of this Cruze prototype alongside the current model, and here, we can clearly see some big visual changes are in store for the new model. The 2015 Cruze's hood slopes downward more dramatically, the windshield is more heavily raked, and the roofline looks more fluid overall. The next-generation Cruze will ride on the new global Delta platform that will also underpin other General Motors vehicles like the Chevrolet Volt and Equinox.
As for what's under the hood, we expect the normal range of gasoline four-cylinder engines (both naturally aspirated and turbocharged), and the compact's new turbodiesel four should carry over, as well. Have a look at the full brace of spy photos in the gallery above.
