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.

Chevy to show redesigned Captiva in Geneva, will it come to US rental lots?

Unless you're renting a car or driving through Orlando, Florida (the rental car capital of the US), you'll probably never see a Chevrolet Captiva - the rebadged, fleet-only version of the old Saturn Vue - on our roads, but this crossover is popular in many other parts of the world. As such, Chevrolet announced that the Captiva will be getting an update for 2013, which will be unveiled next week at the Geneva Motor Show.
Coming off a pretty extensive refresh in 2011, the 2013 model year will bring even more changes to the Captiva like LED taillights, new 18-inch wheels and revised fascias with a new grille and fog lights up front and inset chrome exhaust outlets at the rear. New interior features include heated rear seats, dual-zone climate control as well as available options on some of the upper trim levels such as leather seating and keyless entry and start. We have yet to hear back from Chevrolet as to whether or not the updated Captiva will be making its way to a rental lot near you, as the model is only available in the US to fleet buyers.
Alongside the updated Captiva, Chevy is also showing off its new Trax in Europe, where the subcompact crossover will go on sale this spring. GM's press release for these two Geneva-bound models is posted below.

Camaro spy shots show subtly different grille, front fascia

It looks like there some changes in store for the Chevrolet Camaro - the only thing is that we just don't know what Chevy has up its sleeve. Looking at these spy shots, we'd initially be inclined to think that there is just a minor facelift or a new special edition, but upon closer inspection, there are a few oddities about this car that definitely have us intrigued.
The most obvious difference on this prototype is the slightly restyled front fascia with a smaller lower air inlet and the two-bar grille. Then we get to some of the car's mysterious details. For starters, this fascia has the SS vent above the grille, but it looks to be blocked off. Granted this could just be a one-off piece used for testing. What really piqued our interest was at the rear of the car where it has quad exhaust outlets that are used on the ZL1. Could this be the LS7-powered Camaro that we reported on back in December?
At this point, your guess is as good as ours as to what we're looking at here, so let us know in the comments what you think this could be.
