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 Silverado HD gets the Custom Sport treatment

Everyone remember the Silverado 1500 Custom Sport Chevrolet showed at the 2015 Detroit Auto Show? Good. Now, the company has applied the same styling treatment to its heavy-duty pickups, introducing the 2500 and 3500 Custom Sports. The two trucks appeared today at the 2015 Denver Auto Show. A monochromatic look is the order of the day, with the heavy-duty Silverados getting body colored bumpers both fore and aft as well as a body color grille. Chrome accents sit in said grille, while the shiny finish can also be found on the door handles and mirrors. Buyers of the 2500 Custom Sport will get five-spoke, 20-inch, polished wheels, while the brawnier 3500 gets 18-inch polished hoops as standard (dualies are downgraded to 17-inchers). Custom Sport models are only available in Summit White or Black. The trim package can be added to both LT and LTZ models, with a price premium ranging from $700 to $1,695, depending on the truck.

That time we lapped Indy with Tony Kanaan in a Corvette Z06

We're here in Indianapolis, IN, attending this weekend's 99th running of the Indy 500. The big event happens tomorrow, but the city is buzzing today with all sorts of pre-race festivities. For us, that means checking out Indianapolis Motor Speedway a day early, and getting a hot lap around the racetrack in the official Indy 500 pace car – a 2015 Chevrolet Corvette Z06. Our driver for the occasion is IndyCar racer Tony Kanaan, who won the Indianapolis 500 in 2013. Of course, he'll be competing tomorrow, leaving pace duties to none other than Jeff Gordon. Check out our minute-and-a-half-long lap of the Indy 500 track in the video above, where Kanaan hugs the wall in true race style, getting the Z06 past 150 miles per hour on the back straight. Stay tuned for more Indy 500 coverage later this weekend.
