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.

Outrageous Thor24 semi truck to appear in the new season of 'Jay Leno's Garage'

Wednesday is Jay Leno's birthday, and CNBC used the occasion to announce the upcoming season of Jay Leno's Garage. In a new teaser video, Leno is seen with a stacked list of guests, some new, some repeats, as well as a wild gamut of vehicles, including the absolutely insane 24-cylinder, 3,424-horsepower Thor24.  The outrageous semi build, which sold at auction in Saudi Arabia earlier this year for a whopping $12 million (or $1 million per supercharger) will join the likes of the Tesla Cybertruck and a recliner on wheels on the upcoming season of Jay's series.  Thor24 View 24 Photos The formula for Jay Leno's Garage is simple, successful, and not changing anytime soon. He brings out a bunch of famous people, some of which are real enthusiasts, others who have more casual driving backgrounds, and they experience a vehicle together. In the short clip released by CNBC, Leno is accompanied by Elon Musk (again), Danny Trejo, Bill Burr, Tim Allen, Jon Hamm, Brad Garrett, Jeff Dunham, Kelly Clarkson, Matt LeBlanc, Blake Shelton, Norm MacDonald, Edd China, and Jon Lovitz.           View this post on Instagram                   Thank you for sharing your dream with us.

This season will include the Tesla Cybertruck, the record-breaking Bugatti Chiron Super Sport 300+, a 1965 Buick Riviera, a naked cat car, an Aston Martin DBS Superleggera, a Porsche Taycan, a modern Ford GT, a Chevrolet Corvette C8 hard-top convertible, amphicars, a snail car, a beetle car, a couch car, and the 24-cylinder, 12-supercharger, 3,424-horsepower Thor24 semi. Just to name a few. As usual, there will be racing, stunts, spinouts, smoke from both tires and engines, and lots of silly dad jokes.

GM to squeeze out more production capacity for midsize trucks

General Motors was predicting a strong showing for the Chevrolet Colorado and GMC Canyon before they debuted, and demand among dealers for the midsize trucks even exceeded company's expectations. The positive situation has left GM with a problem, though: finding ways to increase capacity for the pickups at the Wentzville Assembly plant in Missiouri. With a third shift already running, GM has continued to look for ways to build just a few more of the trucks at the plant. The company has plans to hire as many as 1,000 more workers for the Saturday and Sunday shifts to construct an additional 2,000 pickups a month, according to unnamed insiders at the factory speaking to Automotive News. The little adjustments even extend to getting rid of an unpaid break to add 18 minute of assembly time over the course of a day, which equals about 3,500 more vehicles a year. All of this effort comes because the trucks are in such high demand. According to GM's figures, the company has delivered a combined 35,720 units of the Colorado and Canyon from January through April 2015, and the Chevy was the fastest-selling truck in the US for the previous three months. In May, it spent an average of just 12 days in showrooms before being snapped up. And even better for the company, 43 percent of these buyers came from other brands. According to Automotive News, the most popular trade-ins have included the Ford F-150, Toyota Tacoma, and Dodge Dakota. Related Video:
