2016 Camaro gets most revealing tease yet

Chevrolet started its long teaser campaign for the 2016 Camaro by just revealing the exhaust manifold and front frame, but as time has passed the company has slowly unveiled more. In the latest glimpse ahead of the pony car's May 16 debut, we're actually getting to see the model's profile completely undisguised. As suggested by the recent tease of the rear and hood, the 2016 Camaro wears a sharper, more angular design than the current model. This is especially the case when you look at the taut lines making up the rear. Chevy claims that the new shape underwent 350 hours of wind tunnel tests to be able to generate left lift, improve cooling and reduce wind noise in the cabin. A smooth underbody pan is among the aerodynamic tweaks, and it runs from underneath the front grille to the center of the Camaro. Chevy asserts that all of the changes at the front help reduce lift by 30 percent.

These changes illustrate the lengths the aerodynamics team went to for improved performance, stability, cooling and lower wind noise intrusion "The importance of aerodynamics increases exponentially as we increase vehicle performance," said Kirk Bennion, Exterior Design manager. "As engine output increases, we need more engine cooling. As acceleration and top speeds climb, we need to reduce lift for better high-speed stability. However, we cannot make any changes at the expense of increasing drag, which can hurt fuel economy. "To balance these different aerodynamic targets, we tested literally hundreds of changes on the new Camaro, millimeters at a time." For example, the initial design called for the lower grille bars to be set at a 20-degree angle to the horizon. However, after meticulous testing, the team improved engine-cooling airflow by 1 percent by shifting the angle to 13 degrees – a change that achieved the airflow target while maintaining the original grille design. And rather than a traditional front air dam to reduce aerodynamic lift, the team developed a flush belly pan that stretches from the front grille to the center of the vehicle.

Nissan Leaf sets new November sales record, Chevy Volt drops again

When you talk to people in the plug-in vehicle industry, one theme you hear repeatedly is that the more plug-in cars that are out there, the better things are for everyone. One reason is that more EVs build a need for more public chargers, and more chargers mean more people see that plugging in is feasible. But there's still something to be said for old-fashioned competition, and in the sales race between the two long-running plug-in vehicles in the US, the Nissan Leaf is resoundingly beating the Chevy Volt for 2014. In fact, it won't be long before the EV's cumulative sales top the PHEV's. But that's a topic for another month. For now, we have the sales results from November. Unsurprisingly, Nissan set another monthly record (that is, the best Leaf sales in any November, the 22nd time in a row we've seen a monthly record) with 2,687 sales last month. That's up 34 percent over last November and up 35 percent year-to-date. Toby Perry, Nissan's director of electric vehicle marketing, said in a statement that, "Our 'Kick Gas' ad campaign and 'No Charge to Charge' launch in Chicago and Atlanta drove an increase in November Leaf sales. Even with gas prices falling across the country, consumers appreciate that the cost of driving a Nissan Leaf is still a fraction of that of a gas-powered car." Over on the Chevy side of the ledger, there were 1,336 Volt sales last month, down 30.4 percent from the 1,920 sold in November 2013. So far this year, Volt sales are down 16.4 percent and Chevy has sold 17,315 Volts in 2014. As we said last month, the Volt slump might be due to people waiting on the new version to make an appearance at the Detroit Auto Show next month before going on sale in the second half of 2015. So far in 2014, Nissan has sold 27,098 Leafs. Look for our detailed post of US green car sales in the near future. Until then, please discuss last month's Leaf and Volt sale in the comments, below.

GM diesel pickups first to undergo extra EPA, CARB testing

The effects of Volkswagen's long-running diesel emissions evasion are starting to spill over to other automakers, but General Motors is taking things in stride. The 2.8-liter, four-cylinder Duramax in the 2016 Chevrolet Colorado and GMC Canyon is the first engine to get extra scrutiny by the Environmental Protection Agency and the California Air Resources Board, Automotive News reports. Rather than just the usual in-lab test, it's also being checked on the road. However, the extra evaluation shouldn't have any impact on when the trucks with his mill hit dealers later this fall. "We're in our final stages of the EPA certification, and our launch is on track," Chevy spokesperson Otie McKinley tells Autoblog. The four-cylinder diesel in the trucks makes 181 horsepower and 369 pound-feet of torque, and the automaker is touting low NOx production. In the announcement for the Colorado's specs, the company calls it "the cleanest diesel truck engine ever produced by General Motors." The tech includes exhaust gas recirculation to lower combustion temperatures and improve emissions. There's also a urea tank like on the bigger diesels for full-size trucks, and it gets refilled in time with oil changes. An indication on the instrument panel lets drivers know when that's needed, too. Even with the more demanding testing, the company doesn't seem too worried about the four-cylinder passing. "Part of our development process is on-road and off-road [laboratory] testing," Scott Yackley, Chevy Trucks assistant chief engineer, said to Automotive News. In the wake of the VW scandal, the EPA has pledged more rigorous testing. Before, on-road emissions evaluations were largely limited to heavy-duty vehicles, but the agency has decided to apply the checks more often to other models. There's also now greater cooperation with Canadian authorities.
