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 rolls out Corvette Z06 C7.R Edition at SEMA

It's not just concept vehicles that Chevy is showcasing at SEMA this year. The Bowtie brand is also taking the occasion of the tuner expo to reveal the new Corvette Z06 C7.R Edition. The special edition of the flagship performance model pays tribute to the racing model with a series of special touches and upgrades. The C7.R edition is based on the Z06 in 3LZ trim, and comes equipped with the Z07 Performance Package, including Brembo carbon-ceramic brakes and Michelin Pilot Sport Cup 2 tires. But that's not the end of the story. It also includes special graphics, yellow brake calipers, yellow-striped black wheels, a carbon ground effects package, carbon hood section, metallic gray grilles and vents, and a black leather interior with sueded microfiber trim, Competition Sports seats, and yellow stitching. Buyers will be able to order theirs in black or yellow and in either coupe or convertible body-styles. Only 650 examples will be made, of which 500 will remain in the United States, and each of them is individually numbered starting with the VIN 700001. Of course, being based on the Z06 we already know, it packs a 6.2-liter supercharged V8 engine good for 650 horsepower and an equal measure of torque. With the Z06 pack, that translates to a 0-60 time of under 3 seconds for the automatic version and 3.2 for the manual.

The Corvette Z06's capability is derived in no small part from technology and experience leveraged from the championship Corvette Racing program. That connection is celebrated with the 2016 C7.R Edition. It's offered in Corvette Racing's signature yellow livery – or black – with coordinated exterior and interior accents. Only 650 will be built (500 for the U.S. market), all with the Z07 Performance Package with carbon ceramic brakes, and a specially serialized vehicle identification number.
