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.

IIHS: High numbers of drivers treat partially automated cars as fully self-driving

WASHINGTON — Drivers using advanced driver assistance systems like Tesla Autopilot or General Motors Super Cruise often treat their vehicles as fully self-driving despite warnings, a new study has found. The Insurance Institute for Highway Safety (IIHS), an industry funded group that prods automakers to make safer vehicles, said on Tuesday a survey found regular users of Super Cruise, Nissan/Infiniti ProPILOT Assist and Tesla Autopilot "said they were more likely to perform non-driving-related activities like eating or texting while using their partial automation systems than while driving unassisted." The IIHS study of 600 active users found 53% of Super Cruise, 42% of Autopilot and 12% of ProPILOT Assist owners "said that they were comfortable treating their vehicles as fully self-driving." About 40% of users of Autopilot and Super Cruise — two systems with lockout features for failing to pay attention — reported systems had at some point switched off while they were driving and would not reactivate. "The big-picture message here is that the early adopters of these systems still have a poor understanding of the technologyÂ’s limits," said IIHS President David Harkey. The study comes as the National Highway Traffic Safety Administration (NHTSA) is scrutinizing Autopilot crashes. Since 2016, the NHTSA has opened 37 special investigations involving 18 deaths in crashes involving Tesla vehicles and where systems like Autopilot were suspected of use. Tesla did not respond to requests for comment. Tesla says Autopilot does not make vehicles autonomous and is intended for use with a fully attentive driver who is prepared to take over. GM, which in August said owners could use Super Cruise on 400,000 miles (643,740 km) of North American roads and plans to offer Super Cruise on 22 models by the end of 2023, did not immediately comment. IIHS said advertisements for Super Cruise focus on hands-free capabilities while Autopilot evokes the name used in passenger airplanes and "implies TeslaÂ’s system is more capable than it really is." IIHS in contrast noted ProPILOT Assist "suggests that itÂ’s an assistance feature, rather than a replacement for the driver." NHTSA and automakers say none of the systems make vehicles autonomous. Nissan said its name "is clearly communicating ProPILOT Assist as a system to aid the driver, and it requires hands-on operation.

2016 Chevy Colorado Duramax makes 369 lb-ft for $3,730 premium

Since announcing the new Chevrolet Colorado in late 2013, there has been absolutely no secret that the 2.8-liter Duramax diesel would wind up under the hood of the midsize pickup truck for the 2016 model year. It has been a long wait for those wanting the oil-burner, but thankfully, the anticipation is nearly at an end. Chevy is finally officially unleashing details about the four-cylinder, which churns out 181 horsepower and 369 pound-feet of torque. The diesel is available in both LT and Z71 Crew Cab trims, and there's the choice of two- or four-wheel drive. All come with a six-speed automatic gearbox with a standard automatic-locking rear differential. An electronically controlled two-speed transfer case comes on four-wheel drive models, as well. The Z82 trailering package also arrives on all of the Duramax pickups and includes an exclusive integrated trailer brake controller. The first shipment of diesels arrives at dealers this fall with a price of $3,730 on top of a comparably equipped version with the 3.6-liter V6. Customers opting for the Duramax are getting more capability from the Colorado. With a 7,700-pound tow rating on two-wheel drive examples (7,600 pounds with four-wheel drive), drivers can haul 600-700 pounds more behind the truck than its petrol V6 counterpart. Fuel economy numbers haven't been announced yet, but are expected to top the gasoline versions. The engine is also B20 bio-diesel compatible. Beyond being just a good hauler, Chevy is throwing cutting-edge tech into these models. For example, this is the company's first application of a Centrifugal Pendulum Vibration Absorber on the transmission's torque converter. The device is a dampener that cancels out torsional vibration from the engine for a more comfortable ride for occupants. There's also a driver selectable exhaust brake system that uses engine compression to help slow down the truck and reduce brake wear.
