2016 Chevy Colorado Duramax gets 31 mpg highway

The 2016 Chevrolet Colorado Duramax and its similarly diesel-powered GMC Canyon sibling are the most fuel-efficient new trucks on the market in America. The Environmental Protection Agency estimates 31 miles per gallon highway, 22 mpg city, and 25 mpg combined for two-wheel-drive Colorado and Canyon diesels. That's just good enough to take the pickup fuel-economy title from the Ram 1500 EcoDiesel HFE, which carries EPA estimates of 29 mpg highway, 21 mpg city, and 24 mpg combined. Four-wheel-drive models offer slightly lower economy figures of 29/20/23, respectively. Drivers can cover quite some distance, too – the GM twins' 21-gallon tanks mean a maximum range of 651 miles. <p>Your browser does not support iframes.</p> Diesel's reputation may be somewhat tarnished in the US after Volkswagen's emissions scandal, but Chevy wants to assure potential customers that there are no tricks with the Colorado's figures. The pickup's engine features NOx-reducing tech like exhaust gas recirculation, and the EPA and California Air Resources Board recently chose the truck to take the additional step of real-world emissions tests. The 2.8-liter Duramax four-cylinder with 181 horsepower and 369 pound-feet of torque had no problems with the more stringent evaluation, and "the agency expressed no issues or concerns," according to the company's statement. The diesel Colorado goes on sale this fall, and the Duramax costs $3,730 over a similarly equipped V6 model. We've gone ahead and included dueling press releases from both Chevy and GMC below for your reading pleasure.

The EPA-estimated highway fuel economy for 2016 Colorado four-wheel drive diesel is 29 mpg. The EPA has issued a Certificate of Conformity for the Chevrolet Colorado Duramax diesel.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).

Chevy Malibu rolls over 10 million on the odo

On the cusp on the introduction of the latest model, the Chevrolet Malibu is celebrating a major milestone with 10 million of them now on the road since the car's introduction 51 years ago. While not quite enough to rank among the best-selling vehicles of all time, the feat is impressive considering the name took over a decade off from the Chevy lineup in the '80s and '90s. The Malibu started life in 1964 as the top trim on Chevy's new, midsize model, which also included the 300 and Chevelle. Offered in a plethora of body styles, including a wagon and convertible, the Bowtie brand moved over 370,000 of them in the first year. By 1969, sales reached more than 503,000. However, the market for rear-wheel drive sedans eventually softened in the US, and the Malibu name was dropped in 1983. The moniker returned in front-wheel-drive form in 1997 and has been a part of the lineup again ever since. These days, the Malibu is obviously only available as a four-door, but the model is more efficient than ever. The larger, lighter 2016 example can get up to 37 miles per gallon highway with its 1.5-liter turbocharged four-cylinder or 47 mpg combined when the hybrid goes on sale next year. You can get a great look at the Malibu's changes from the original until now in the gallery above.

Chevrolet celebrated the sales achievement today for the global sedan in the United States, China and Korea, which collectively account for more than 90 percent of sales. The Malibu is sold in more than 25 markets around the world. "The Chevy Malibu joins an exclusive club of vehicles that have achieved this extraordinary milestone and we acknowledge it today by honoring the common thread linking every one produced: The customer," said Alan Batey, president, global Chevrolet. "Some people are buying their very first Malibu today and others may have driven a Malibu from a different generation as their first car. It is a car that has resonated with customers for more than half a century." Chevrolet's interaction with customers has evolved since the Malibu was introduced in 1964. Back then, an owner's manual and a personal relationship with the dealer defined conventional customer service.
