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. Related VIdeo: 2016 Camaro is all about the Aero Total aerodynamic lift improved by 30 percent for improved stability 2015-05-11 DETROIT – After 350 hours of wind tunnel testing – often 24 hours a day – the new Camaro will slip more easily through the wind, and drivers of the Camaro SS will experience a marked improvement in reduced aerodynamic lift. 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.

2016 Chevrolet Colorado Diesel First Drive [w/video]

The first thing you notice inside the diesel Chevy Colorado is that it's quiet. Almost too quiet. A lot has been done to quell noise and vibration with this new powertrain, and it shows – or rather, doesn't. There's some characteristic diesel clatter at idle, but even then it's distant and practically disappears as you start moving down the road. At full throttle, when the engine is at its noisiest, the sound isn't particularly diesel-like, just a pleasant intake breath. The accompanying smoothness is almost eerie. When we ask where all the noise went, Chevy's engineers, marketing guys, and PR reps all explain that this refinement is what Americans want. We're still not sure. This is a truck, after all, and the diesel pickup customer is different from the guy buying a diesel Cruze for his highway commute. Chevy contends that they're also not the same as the buyer of a Silverado HD. Although this 2.8-liter Duramax four-cylinder has been in service elsewhere around the globe, its first US application is in the Colorado and its GMC Canyon twin. The engine puts out 181 horsepower and 369 pound-feet of torque, and it does so unobtrusively as a result of a lot of modifications for our market. To keep normal diesel sensations out of the cabin, the intake and oil pan both get acoustic treatments. A new, thicker material is used for firewall sound deadening. Redesigned balance shafts have tighter tolerances to increase smoothness. The diesel powertrain is smoother than the Colorado's gasoline V6. One of the more interesting and certainly unexpected vibration-reduction changes is a special torque converter from German supplier LuK equipped with a centrifugal pendulum absorber. This pendulum spreads from the center of the torque converter as engine speed increases and is tuned to absorb the four-cylinder's second-order vibrations, not just those in a narrow frequency band. It does an admirable job, especially considering the engine's biggish, 0.7-liter cylinders, which lead to bigger vibrations. The result is a powertrain that's smoother than GM's (not particularly smooth) corporate V6, which is available in the standard Colorado. It's quieter than a Cruze diesel and even out-softens some gas direct-injection engines on the market. Paradoxically, it may be the most refined of all of the Colorados. No vibration comes through the steering wheel, pedals, floorboards, or even the rearview mirror. But you can tell it's a diesel when you hit the throttle.

Chevy 'committed to marketing Bolt the right way'

The 2015 edition of the annual AltCar Expo in Santa Monica, CA in September was a relatively quiet affair. Attendance felt light compared to previous years. But that didn't mean there wasn't something happening that might have just as big an impact on the plug-in scene as anything that's ever happened in previous years at the Santa Monica Convention Center. I say this because of what GM's Shad Balch told me about Chevy's plans to market the upcoming Bolt electric car. This is GM's next-gen electric vehicle, which will have a roughly 200-mile range and may cost about $30,000 after tax incentives (maybe). To say he's excited to start selling this car is an understatement. Set aside the obvious challenge Chevy will have with cars named both the Volt and the Bolt, especially when some languages exchange the pronunciation of the letters B and V. Set aside the fact that, for now, Balch is dealing with his own company actively advertising against the product he's trying to get people excited about. Balch, GM's manager of new product and public policy communications, is tremendously positive about the Bolt's chances in the marketplace when it arrives in 2017 or 2018. "Driving an EV is, in every proof point, better than a gas-powered car, except for charging." - Shad Balch AltCar and the concurrent National Drive Electric Week represented the Bolt's West Coast debut, and Balch told me that the car's arrival in California shows how "Detroit recognized that they need to send it out to their number one market." The car's appearance outside of the Motor City was "The most encouraging part for us out here, being in the market ... to be able to explain that we are committed to marketing this car the right way. ... We're trying to make that known as much as possible, because that is the number one criticism that we hear. That's why events like these are so important, because we can't wrap up into a 30-second spot what these cars are capable of. I can't even explain it to you in 10 minutes what it's like. But the thing is, driving an EV is, in every proof point, better than a gas-powered car, except for charging." Now, there's a fairly decent chance that GM will hit the 250,000-vehicle limit for the $7,500 federal tax incentive right about when the Bolt comes to market, so I had to ask how the Bolt gets marketed if the price tag jumps up a few thousand dollars. Balch was straightforward. "Well, we would sell fewer cars," he said. "It's pure and simple. ...
