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.

GM recalls 740,000 vehicles over daytime running light issue

General Motors is recalling over 740,000 vehicles due to a daytime running light issue that causes all of the affected cars to run afoul of Federal Motor Vehicle Safety Standards. Vehicles affected by this recall are spread across many of GM’s brands. Models include the 2020-2023 Cadillac CT4 and CT5, 2021-2023 Buick Envision, 2022-2023 Cadillac Escalade and Escalade ESV, 2022-2023 Chevrolet Silverado 1500, Suburban, Tahoe and 2022-2023 GMC Sierra 1500, Yukon, and Yukon XL. GM says that the daytime running lights may remain on in these cars when the headlights are activated. This is a problem, because FMVSS rules require that the daytime running lights deactivate once the headlights turn on. If the DRLs remain on, GM says that could result in additional glare, thereby increasing the risk of an accident. The cause of this failure to deactivate the DRLs comes from body control module software that “under a combination of certain pre-conditions, could fail to deactivate the DRLs,” according to GM. Other GM vehicles were tested, but due to a difference in software or hardware, they remain unaffected. If this is reminding you of another recent GM recall, youÂ’d be right, as GM recalled another 340,000 vehicles for the same issue last month. After that original issue was found within GM, the company began looking into its other cars to determine if the population was larger than originally thought. GM found the additional vehicles included in todayÂ’s recall have the problem. The fix will either be via an over-the-air update or it will require you to bring the vehicle into a dealer for a software update, depending on which vehicle you have. Owner notification letters letting folks know what is necessary are currently scheduled to go out on January 23, 2023. Related video: Cadillac Escalade Infotainment Review

GM resumes production of its 3.0-liter turbodiesel straight-six

General Motors temporarily stopped taking orders for trucks and SUVs equipped with the 3.0-liter Duramax turbodiesel six-cylinder engine in August 2021 due to a supplier shortage. Reports claimed the pause would last through 2021, but the engine is already back in production. Enthusiast website GM Authority learned from sources inside General Motors that the straight-six is once again coming off the assembly line at the Flint Engine Plant in Flint, Michigan. There's no official word on precisely what the problem was linked to and whether it was related to the on-going chip shortage that's wreaking havoc across the automotive industry. All we know is that the pause lasted for about two weeks. Called LM2 internally, the six is available in Chevrolet's Tahoe, Suburban, and Silverado 1500 and in GMC's version of these trucks. It's also an option in the Cadillac Escalade. It develops 277 horsepower at 3,750 rpm and a V8-like 460 pound-feet of torque at 1,500 rpm in every application, and it allows these big behemoths to post surprising fuel economy numbers. Fitted to a rear-wheel-drive Tahoe, the Duramax returns 21 mpg in the city, 28 mpg on the highway, and 24 mpg in a combined cycle, figures that make it more efficient than a Blazer. Demand for the diesel-powered trucks is relatively high. While the shortage undoubtedly took a toll on sales, the Duramax represented 8% of Suburban sales and 6% of Tahoe sales in May 2021. There are no other diesel-burning full-size SUVs available new so they have the market to themselves. On the truck side, Ram still makes the EcoDiesel available on some 1500 trims but Ford abandoned the segment.
