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.

Nissan Leaf is now the best-selling plug-in vehicle of all time in US

Numbers don't lie. And in some instances, you can see their truth from miles away. As everyone expected, the Nissan Leaf is now officially the best-selling plug-in vehicle in the US. While the two vehicles aren't direct competitors (one's a pure EV and the other is a plug-in hybrid), they certainly dominate the plug-in vehicle sales charts. When we do a little math on those charts, we see that since the two vehicles went on sale at the end of 2010, the Volt has sold 75,231 units while the Leaf is now at 76,407, giving the Leaf a 1,176-vehicle lead. The Leaf trailed the Volt by just two units at the end of February. This is the first time the EV had held the overall lead since the end of February 2012, when it was ahead 10,847 to 9,623 and for a while there at the end of 2013, the Volt was up by around 12,000 units. Times have changed, though, and we don't expect the lead to switch back until the next-gen Volt goes on sale later this year, and even then nothing is certain. The Leaf sold 1,817 copies last month, a drop of 27.5 percent from last year. Year-to-date, the Leaf has sold 4,085 units, down 21.2 percent from the same time period in 2014. There were 639 Volts sold last month, a 56.8-percent sales decrease compared to March 2014. So far this year, Volt sales are down 48 percent. Green Chevrolet Nissan ev sales hybrid sales

Recharge Wrap-up: BYD electric buses at Special Olympics, hybrids perform better than rated

A new study finds that real-world fuel economy of hybrids could be significantly higher than EPA ratings. Researchers at the University of Vermont, with the help of their own "total on-board tailpipe emissions measurement system," found the fuel savings of Toyota Camry Hybrid over a standard Camry to exceed its sticker values by 18 percent on the highway and 33 percent in the city. The results of this study suggest that the projections of the fuel and emissions benefits of hybrids could be adjusted to reflect more these more positive real world values. The study's authors, Britt A. Holmen and Karen M. Sentoff, say more research is warranted based on these findings, and that "similar studies can be used to develop robust models of all types of HEV platforms under actual driving conditions and improve quantitative estimates of the future fleet contributions to the US CO2 emissions inventory and petroleum consumption."

Chevy displayed the silver Volt alongside a Camaro and Malibu of the same color and model year. The Volt also recently made an appearance at the premier of Tomorrowland with George Clooney behind the wheel. Read more at The News Wheel. BYD electric buses provided transportation at the Special Olympics 2015 World Games in Long Beach, CA. Shuttling 6,500 athletes required the help of multiple charter companies, including local buses from the Chinese automaker. "BYD stepped up majorly as one of our key supporters and their tremendous efforts made our athletes feel welcomed," says Long Beach Community Foundation President and CEO, and 2015 Host Town Transportation Coordinator Marcelle Epley. "We depended on them, and they came through 100 percent." Both Los Angeles and Long Beach have recently decided to purchase electric buses from BYD. Read more in the press release below. BYD Zero-Emission Buses Used to Transport Athletes at 2015 World Games LONG BEACH, Calif., Aug. 2, 2015 /PRNewswire/ -- This week the largest Special Olympics ever was hosted in the City of Long Beach – thousands of athletes, coaches, dignitaries and families descended upon Los Angeles for what was a spectacular week of uplifting camaraderie, sportsmanship and competition.
