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 says EVs are the future — but trucks are going to take it there

In the PowerPoint deck for the General Motors Capital Markets Day presentation, one of the more disturbing things comes early on, during GM President Mark Reuss' initial remarks, in an area where he is discussing the company's overall strength in trucks. The point being made is that GM has a truck for all and sundry. And there it is, a phrase on a slide that should send chills up the spines of those who still pine for the old Bob Seger "Like a Rock" Silverado ads: "Little bit country. Little bit rock 'n' roll." That's right. Donny and Marie. Somehow the Denis Leary snark in the F-150 ads is all the more appealing. The Capital Markets Day presentation was chock full of observations about electrification and automation (Reuss and CEO Mary Barra both noted that the corporation's vision is one of "Zero Crashes. Zero Emissions. Zero Congestion." Dan Ammann talked about the progress being made at Cruise Automation; Reuss rolled out the plan for an array of electrified vehicles, with a luxury EV and a compact SUV being the "Centroid Entries" for the modular bases of many others). But it is worth noting that there is no getting away from the power of pickups in the U.S. market, as that was the central topic in Chief Financial Officer Dhivya Suryadevara's comments, with "Truck Franchise" being flanked by "Key Financial Priorities" and "Financial Outlook." Clearly, to gloss the old phrase, the truck segment is where the money is. Suryadevra enumerated how the truck segment is significantly different than other types of light vehicles. Among her points: GM, Ford and FCA have more than 90% of market share. The truck parc has been growing and aging over the past 10 years. Customers are fiercely loyal to the segment—as in 70% of truck buyers are truck buyers. A good number of the vehicles are for commercial use (40 percent). Trucks are "less prone to. . .mobility disruption." Trucks offer high margins. Translaton: The segment is one that they're solidly positioned in. There are lots of old trucks on the road that will need to be replaced by new ones. Perhaps buyers may switch from a Sierra to a Canyon, but it will be a truck. If your livelihood depends on that type of vehicle, even if gas prices go up or the economy begins to go south, you're going to stick with it. Most of the country isn't San Francisco, so trucks will continue to be essential. And, well, they're profitable in the extreme.

How easy is it to rebuild a Chevy small block V8?

Chevrolet's famous small block V8 stands as one of the workhorse engines in American auto history, with its variants going into vehicles from hot rods to pickup trucks. But do you know that you can fully disassemble and completely restore one of these mills in just under four minutes? Well, as long as there's some assistance from time-lapse photography, that is. Hagerty created this short clip showing a dirt-covered small block turning from a frog into a prince. Thankfully, the time-lapse doesn't speed the process up too much, and it's still easy to see how all of the principal parts fit together. With all sorts of sensors and software helping to drive the modern automobile, viewing the internal combustion engine in its purely mechanical form is still fascinating. Related Video:
