2016 Chevrolet Camaro powers up, slims down

Don't be fooled by its familiar appearance, the 2016 Chevrolet Camaro is vastly different than its iconic predecessors. It has a new chassis, a fresh engine lineup, and is loaded with clever technologies that promise to invigorate and improve the sixth generation of Chevy's legendary sports car. It was revealed Saturday before a crowd of enthusiastic Camaro revelers on Belle Isle in Detroit. Redesigning the sports coupe was a heady task, especially as its archrivals, the Ford Mustang and Dodge Challenger, drive better and are more powerful than ever. But the new Camaro is aiming to be the best combination of handling and raw performance, with quick acceleration and competitive fuel economy. "Redesigning the Camaro is thrilling and challenging all at once, but the secret is to offer something more," Mark Reuss, General Motors executive vice president of product development, said in a statement. It all began with a weight-loss plan. The new Camaro shed more than 200 pounds compared with the outgoing car, with 133 pounds coming from a lighter body-in-white. Then engineers culled weight nearly everywhere, using aluminum for the instrumental panel frame and some suspension components to trim as much fat as possible. The slimmer body rests on new bones. The Camaro's rear-wheel-drive platform is lighter and stiffer in a bid to improve handling. It's a modified version of the underpinnings used by the Cadillac ATS, though about 70 percent of the architecture is unique to the Camaro. Chevy said structural rigidity is improved by 28 percent. As you'll see, healthy doses of Cadillac and Corvette technologies have been used to bolster the Camaro's drive character and performance. The new car is also expected to handle better thanks to a slightly smaller footprint. It is about two inches shorter in length, with most of that due to the more compact wheelbase. It's also an inch shorter in height and an inch slimmer in width. So yes, the Camaro will be leaner, but it will still be plenty mean. The Camaro SS tops the range (for now) with the Corvette's 6.2-liter V8 pushing put 455 horsepower and 455 pound-feet of torque. Known as the LT1, is has a cast aluminum block and cast aluminum cylinder heads, and it's fortified with direct injection, variable valve timing, and cylinder deactivation. About 20 percent of the engine's parts are said to be unique to the Camaro, including the exhaust manifolds.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

Chevy SS prototype spotted wearing Pontiac G8 clothes

Do not adjust your computer screen, you are not seeing the rebirth of the Pontiac brand. General Motors has chosen to use a G8 to disguise a test mule for the latest prototype of the forthcoming Chevrolet SS. The G8 was closely related to the Holden Commodore and Vauxhall VXR, the platform upon which the new Chevrolet performance model will be based. It should come as little surprise, then, that GM has opted to use the cladding from the former G8.
Thought the front clip of this mule is pure Pontiac, note the vents immediately behind the front wheel. That is a distinctive design hallmark of the Vauxhall VXR. Also note that this vehicle is right-hand drive, as the Holden and its Chevy counterpart will be very closely related. That likely includes potential drivetrains. The spy photos of this mule also reveal very wide rear tires, and rear wheels that do not match the fronts.
