2022 GMC Sierra Denali Ultimate vs. 2022 Ram 1500 Limited Longhorn vs. Ford F-150 Limited | Luxury truck interior face-off

GMC's new uber-expensive 2022 Sierra Denali Ultimate is the latest luxury truck to nudge toward six-figure territory. With demand for upmarket half-tons surging, GMC's otherwise-solid pickup found itself in desperate need of an interior remodel. For 2022, we're getting just that, and it appears ready to take the fight to the segment's best, including the 2022 Ram 1500 Limited and 2022 Ford F-150 Limited. Here's the new Denali Ultimate interior in all of its full-grain, open-pore glory. 2022 GMC Sierra 1500 Denali Ultimate vs. 2021 GMC Denali  Not only did the material quality and styling both improve greatly, but the new truck also gets a completely different shifter setup (truck buyers don't like column shifters anymore, apparently). It would actually be difficult to overstate the quality of the upgrade here; the photos really speak for themselves. It's also worth noting that in addition to looking significantly more upscale than the model it's succeeding, the new Denali interior also differs a bit more from its Chevy counterpart than its predecessor did. Here's the new Silverado High Country for reference: While some elements do carry over, the entire dash design is different, down to the positioning of the heating and cooling vents. While the main HVAC controls are essentially carried over, note that they're pretty much the only ones. Even the horizontal bar of switches running along the center stack is positioned differently between the two. Yep. This is a pretty big upgrade over the 2021 cabin, and clearly the range-topper in GM's truck hierarchy. But what of the competition? 2022 GMC Sierra 1500 Denali Ultimate vs. 2022 Ram Limited Longhorn Southfork This one's tough. We're going to have to spend time in them back to back, but the Ram Limited, with its various anniversary editions and other special permutations, is certainly the interior to beat. To our eyes, the Sierra's more horizontal layout is a bit more modern and perhaps luxurious-looking than the more upright cabin treatment of the Ram, but it's tough to say for certain from photos. Both the Denali Ultimate and Ram Limited carry their upscale feel into their back benches too, which is something we can't say quite as confidently about our next contestant.  2022 GMC Sierra 1500 Denali Ultimate vs. 2021 Ford F-150 Limited The Ford F-150 Limited holds its own, but it's probably the least photogenic of the models we've looked at here, at least apart from the outgoing Denali.

'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).

2015 Green Car Of The Year finalists announced, run alt-fuel gamut

The 2015 edition of the Green Car of the Year award is following right in the footsteps of previous years with a variety of alt-fuel powertrains making the just-announced finalists list. You've got your plug-in vehicle (the BMW i3), your compressed natural gas (the Chevy Impala Bi-Fuel), your high-efficiency diesel (the Audi A3 TDI), your 40+ mile-per-gallon gas engine (the Honda Fit) and, finally, a car that can do a little bit of everything (the VW Golf). The Golf is available – at least in some parts of the US – with three different powertrains: a 2.0-liter diesel, a gasoline engine and all-electric drive. The Impala can burn either natural gas or gasoline in its 3.6-liter engine. The A3 is an efficiency champ, able to get 73.5 mpg on some European tests. The i3 can be a pure electric vehicle or come with a short range extending engine. And the Fit brings 41 miles to the gallon in a practical, affordable package. The GCOY award is announced every year at the Los Angeles Auto Show by Green Car Journal. The committee doesn't just take the fuel-saving technology into account, but also a vehicle's "availability to the mass market." Last year, the Honda Accord Hybrid/Plug-In Hybrid won top honors, following up on wins from the Ford Fusion models (plug-in hybrid and hybrid) for 2013, the Honda Civic Natural Gas for 2012 and the Chevrolet Volt for 2011. FINALISTS ANNOUNCED FOR 2015 "GREEN CAR OF THE YEAR"" Green Car Journal to Reveal Winner of 10th Annual Award at LA Auto Show" Press & Trade Days, November 20 LOS ANGELES, CA (October 21, 2014) – Green Car Journal has announced its five finalists for the magazine's high-profile 2015 Green Car of the Year® program. The 2015 models include the Audi A3 TDI, BMW i3, Chevrolet Impala Bi-Fuel, Honda Fit, and VW Golf. The Green Car of the Year® award, an honor widely recognized as the auto industry's most important environmental accolade, celebrates its 10th anniversary this year. An increasing number of vehicle models are considered for the Green Car of the Year® program each year, a reflection of the auto industry's expanding efforts in offering new vehicles with higher efficiency and improved environmental impact. Green Car Journal has been honoring the most important "green" vehicles every year at the LA Auto Show, since its inaugural award announced at the show in 2005.
