More Corvette Stingray Factoids: Vanishing panel gaps and 26-mpg LT1

During January's Detroit Auto Show, we managed a longer than expected wandering tag-team interview with C7 Corvette chief engineering exec Tadge Juechter (pictured above), and LT1 engine boss Jordan Lee (pictured below). They are, quite honestly, two of the very nicest bigshot lads to ever walk the engineering corridors of an American manufacturer. Both are enthralled by what they're doing for a day job. So are we.
We've followed the pre-sale anticipation for the Chevrolet C7 Corvette Stingray like an Oreck vacuum yanking every speck of dirt from a well-trampled carpet. Everything is reportable and contains a grain of further knowledge about this dramatically important and cheered-for car, as it continues to be pressured into representing all that is superior about the American dream. The Corvette wears one heavy cloak.
So, most of what was talked about has been expertly reported already right here on Autoblog. But, looking through our notes again, both Jeuchter and Lee added facts to the buzzing mix.

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.

See the new COPO Camaro's awesomeness from many angles

Considering that the COPO Camaro exists solely to drag race, the action you'll see in this video comes as little surprise. Still, Chevrolet Performance wants to prove that the 2016 model, which uses on the sixth-gen body, is just as adept launching down the strip as previous COPOs. This example may still be testing, but its 427-cubic-inch V8 performs like a champ. The engine's raw muscle, at least when coupled with suitably wide and sticky tires, is enough to lift the front wheels when the driver puts the hammer down off the line. This video from Chevy Performance shows off all the drag-strip action from several unexpected angles. You can watch the rear axle at work and even see the engine under the hood during the run. Our personal favorite is the shot of the launch from underneath the car – it's a perspective you never usually get to see. And, naturally, there are lots of great angles showcasing the car's massive burnout potential. The 2016 COPO Camaro debuted at SEMA in 2015. Buyers have a choice of three V8s, and all of them come with a three-speed automatic gearbox, solid rear axle, and adjustable suspension. Relish this opportunity to see the 2016 COPO Camaro at work, but remember, it's a rare beast. As in years past, Chevy plans to build just 69 of them. Over 5,500 people applied to get one in 2016, and the first example brought $300,000 for charity. Related Video:
