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.

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:

2016 Chevrolet Malibu Hybrid Quick Spin [w/video]

If a Chevy Volt is like a hybrid that prefers its electric motor, then the new Malibu hybrid is like a Volt you never have to plug in. That's partly because you can't plug it in, but more because the Volt and the gas-electric Malibu share a lot of major components. Since we happen to like the newly refined Volt, that's good news for the larger family sedan. The shared parts include the blended braking system, A/C compressor, the auxiliary power module, and most of the hybrid transaxle (what you might call a fancy electro-transmission). In the Malibu, the electric motors use neodymium magnets for efficiency and power, while the Volt has weaker ferrite magnets to reduce drag, and the Volt also gets an extra clutch to lock out the engine. The two use different batteries, with their size, power capabilities, and chemistry suited to the task for each vehicle. Unlike most of the midsized sedan leaders, the Malibu has never had a full hybrid option. For a few years in the last generation, Chevy offered the Malibu Eco with a version of GM's eAssist mild-hybrid system, which featured a small motor-generator in place of an alternator hooked up to a bigger battery that could harvest energy during deceleration and add some back in when you hit the throttle; it also brought engine stop-start functionality to save a little more fuel. But it saved only a little fuel, so eAssist was nixed in favor of a more efficient four-cylinder with a standalone stop-start system. Driving Notes Mode switches between gas and electric are just as smooth as in the Volt. No shudder or weirdness in the throttle. It drives as much like a gas-only car as any midsized hybrid does. The blended braking system is also noticeably well sorted. There's no deadness in the pedal, no touchiness, and no artificial, wooden feeling when you step through the regen portion of its travel. There's nothing abrupt or jarring about any of the experience, and the Malibu's baked-in quietness helps to deal with noise from the somewhat coarse 1.8-liter gas engine. Engine startup and shutdown are noisy from outside, but much less noticeable from within. The 2016 Malibu is larger yet lighter. The hybrid weighs about 125 pounds more than a comparably equipped 1.5T. You don't notice the extra weight, but there is some space eaten out of the trunk by the battery.
