Chevy previews 2016 Malibu ahead of New York debut

With everything going on in Geneva this week, it would be all-too easy to forget that there's still stuff going on back home in America. And the upcoming new Chevy Malibu is a prime example. Chevrolet has announced that it is bringing an all-new Malibu to the New York Auto Show next month, teasing us with this preview image and a few enticing details. For starters, when we say it's all new, this time we mean it's all new. The next-generation Malibu has been built on a new platform that uses more high-strength steel to cut 300 pounds off the curb weight compared to the outgoing model. It's also got a wheelbase that's almost four inches longer, with shorter overhangs front and rear and a roofline that tapers stylishly and more gradually towards the tail. We'll have to wait a little longer – but not too much longer – to find out more, but in the meantime you can read what Chevy's telling us so far in the press release below. Born Again: Next-Gen Chevrolet Malibu Announced Larger, lighter and more efficient Malibu to be unveiled at New York Auto Show 2015-03-04 DETROIT – Designed to deliver more efficiency, connectivity and advanced safety features than ever, the next-generation 2016 Chevrolet Malibu will make its public debut at the New York International Auto Show this April. Using a blank slate approach, Chevrolet designers benefited from an entirely new architecture, which for Malibu includes a wheelbase nearly four inches longer than the outgoing model. That, in turn, provides increased rear legroom and interior space. Due to a higher-strength steel structure, the new Malibu is also expected to be 300 pounds lighter than the current model, which benefits the sedan's fuel economy and handling. "Malibu's gorgeous styling is the result of a masterful understanding of proportions," said Ed Welburn, General Motors' vice president of Global Design. "The roofline has been stretched rearward giving a more sleek profile, while the front wheels have moved forward and front and rear overhangs have been reduced. Along with the sculpted body side, these cues help Malibu appear more dynamic and sophisticated." More details about the 2016 Chevrolet Malibu will be shared each week leading up to the vehicle's global debut. The 2016 Malibu is expected to go on sale by the end of 2015. Founded in 1911 in Detroit, Chevrolet is now one of the world's largest car brands, doing business in more than 115 countries and selling around 4.8 million cars and trucks a year.

The Army goes off-roading with a hydrogen Chevy Colorado

The Chevrolet Colorado is joining the service. General Motors is working with the US Army Tank Automotive Research, Development & Engineering Center (TARDEC) to build a Colorado powered by a commercial hydrogen fuel cell stack, and the Army will use it in "extremes of daily military use for 12 months." TARDEC is the department that tests "advanced military automotive technology" and integrates them into ground systems. The aim is to see how well the benefits of a fuel cell vehicle can be adapted to the battlefield; hydrogen-powered vehicles are quiet, torquey, produce water, and can be used to provide electricity in the field. GM says the design sketch above "foreshadows" the Colorado that will go to boot camp and beyond, making it clear that this won't be the average midsize pickup. The press release below has more.

"Hydrogen fuel cell technology is important to GM's advanced propulsion portfolio, and this enables us to put our technology to the test in a vehicle that will face punishing military duty cycles," said Charlie Freese, executive director of GM's Global Fuel Cell Engineering activities. Fuel cell propulsion has very high low-end torque capability useful in off-road environments. It also offers exportable electric power and quiet operation, attractive characteristics to both commercial and military use. "The potential capabilities hydrogen fuel cell vehicles can bring to the Warfighter are extraordinary, and our engineers and scientists are excited about the opportunity to exercise the limits of this demonstrator," said TARDEC Director Paul Rogers. "FCVs are very quiet vehicles, which scouts, special operators and other specialties place a premium," he said. "What's more, fuel cells generate water as a by-product, something extremely valuable in austere environments." GM and TARDEC have fuel cell development and research facilities located 20 minutes apart in Pontiac and Warren, Mich.

'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).
