2016 Chevy Cruze is lighter, loaded [UPDATE]

UPDATE: Live photos and video of the reveal have been added at the end of the story. Chevrolet revealed the second-generation Cruze Wednesday, promising a larger, more efficient car that drives better than the sedan it replaces. We're particularly excited about the new turbocharged, 1.4-liter four-cylinder engine, which makes 153 horsepower, an upgrade from the outgoing 1.8-liter naturally aspirated engine's 138 hp. Torque climbs even more significantly, from 148 pound-feet to 177 in the new mill. Peak twist can be called up between 2,000 and 4,000 rpm, which should make performance easy to access. Combined with a lighter architecture that slashes the Cruze's curb weight by 250 pounds (although the actual curb weight hasn't been released), the new four-door can hit 60 miles per hour in a respectable eight seconds. That's not hot hatchback territory, but it should be more than suitable for the average consumer. That same consumer should also appreciate the new engine's economy. The Cruze now returns an even 40 miles per gallon on the highway and will cover 530 miles on a single tank, all the while running on plain old 87-octane fuel. There's also a diesel-powered Cruze model, although Chevy didn't release specific details, aside from saying that it will arrive in dealers in 2017, over a year after the gas-powered model's early 2016 on-sale date. Despite the 250-pound drop in weight, the new Cruze has grown significantly. Its wheelbase is now the longest in the segment, with 106.3 inches of sheetmetal between the front and rear axles compared to 105.7 in last year's model, while the sleek new body cuts the coefficient of drag to just 0.29. The overall length increases from 181 inches to 183.7, though the new model is nearly an inch lower overall. That's both good news and bad news for interior space. Rear legroom is up from 35.4 to 36.1, but headroom is down in both the front and backseats by over half an inch. Tech fans, meanwhile, will appreciate the new standard MyLink display. The seven-inch touchscreen is compatible with both Android Auto and Apple CarPlay, while an optional eight-inch display will be offered, as well. 4G LTE wi-fi, heated rear seats, a heated steering wheel, and wireless phone charging will also be offered as an optional extras. New safety features include blind-spot monitoring with cross-traffic alert, lane keeping assist, and forward collision warning.

'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 Bolt-based prototype may be a Buick EV for China

Late last spring, we got a look at a GM prototype that was clearly based on the Chevy Bolt EV, but with updated styling. It seemed like it could be a more crossover-styled Bolt, given the recently trademarked name of EUV. Now we get another look at the prototype, but the bodywork seems less suggestive of a Chevy, and more of a Buick. This vehicle definitely still appears to be based on the Bolt, rather than on another small GM platform. In the photos of it next to the current model, the size, wheelbase and profile are extremely similar. There are differences, though. The nose isn't as sloped or as rounded, and the rear window kicks up a little earlier. The biggest changes are in the front and rear fascias, and it's here that we see hints of Buick. There are prominent air inlets on each side of the front bumper that give the car a more aggressive look. The headlights still have a fairly rounded, organic look, but with little extensions like fangs underneath. The styled running-light section, rounded shape and the smoked lenses seem very Buick-like. The grille features a large badge that doesn't fit the shape of a bow-tie, and is more that of a round logo like Buick's. Around at the back, the full-width taillights stand out, and in the middle there is obviously a round badge, again like a Buick. The wide taillights would also be a natural evolution of Buick's current light design language that uses somewhat wide and thin lights. The rear bumper has been redesigned with new lower taillights. Now that we've established that this seems very much like a Buick, we don't think we'll see this particular version offered here with the badge. This is more likely a Buick version of the Bolt for the Chinese market, where the brand is associated with luxury and has been the spearhead for GM's electric and hybrid models. In fact, the Chevy Volt hybrid was sold there as the Buick Velite 5, which was part of a family of a electrified Velite models. This would probably also carry a Velite badge as well. While we might not see this specific Buick variant, we probably will see it offered as a Chevy in some form. With its more aggressive, crossover shape, it could be the rumored EUV model. Or it could be just a refresh of the current Bolt, since the model has been largely unchanged since its introduction for the 2017 model year. And extrapolating from this prototype, we can see how the headlights could be tweaked to tie into those air scoops as on the Suburban and Silverado.
