2019 GMC Yukon Graphite Edition offers Denali engine and features without the chrome

A sporty-looking option package called RST was recently introduced for the Chevy Tahoe and Suburban that also offered the option of a 6.2-liter V8 and magnetic suspension. Now GMC is getting in on the action with the GMC Yukon and Yukon XL Graphite Edition. The trim package adds a number of visual enhancements, and, if you're so inclined, has a performance version with the same 6.2-liter V8 and magnetic suspension as the Tahoe RST and Yukon Denali. As for appearances, the Graphite Edition adds black trim almost everywhere, including the roof rails, grille, fog light surrounds, and window surrounds. It also adds 22-inch wheels, regardless of whether it's just the appearance version or the performance version. The appearance package has machined-finish wheels, and the performance package has black painted wheels. As previously mentioned, the performance version of the Graphite Edition adds magnetic suspension and the 6.2-liter V8 with 420 horsepower and 460 pound-feet of torque found on the Denali and the Tahoe and Suburban RSTs. It's coupled to a 10-speed automatic transmission, and gets a rear axle ratio of 3.23:1. It also gets a few other Denali features such as a color heads-up display, Bose noise cancellation, a 170-amp alternator, and a trailer brake controller. The Graphite Edition can be had with both two-wheel drive or four-wheel drive. The Graphite Edition can only be had on Yukon and Yukon XL SLT models. Pricing hasn't been announced yet, but it's likely it will be a bit more affordable than buying a Denali model.

GM 6.2L EcoTec V8 rated at 21 mpg by the EPA

General Motors is already laying claim to best-in-class power for its new 6.2-liter V8 that will be offered in the 2014 Chevy Silverado and GMC Sierra this fall, and now it has released fuel economy numbers for the big engine. Available as an option on the Silverado LTZ and High Country (shown above) models as well as the the Sierra SLT and Denali trims, the 6.2L EcoTec3 V8 will return 15 miles per gallon in the city and 21 mpg on the highway on rear-wheel-drive trucks; these numbers drop by one mpg each on four-wheel-drive models.
These estimates are in addition to the engine's 420 horsepower, 460 pound-feet of torque and max trailering capacity of 12,000 pounds, and considering all that power it's not terribly far away from the fuel economy of GM's equally new 4.3-liter V6 and its rating of 18 mpg city and 24 mpg highway. This announcement comes just days after a report indicated that GM is unable to keep up with the demand of the 5.3-liter V8 in the fullsize Chevy and GMC trucks due to supplier issues. GM's official press release for the 6.2-liter V8's fuel economy is posted below.

Next-gen Chevy Silverado and GMC Sierra may use carbon fiber

It's been generally accepted that the next generation of full-size GM trucks will use some sort of strong, lightweight material for the beds while retaining steel for the cab. While aluminum seems like the most obvious choice, according to Automotive News, the Chevy Silverado and GMC Sierra will incorporate both aluminum and carbon fiber in their beds. The publication cites sources from within GM, though it seems the introduction of this comparatively exotic material mix is still a few years off. While carbon fiber is both stronger and lighter than steel and aluminum, it takes significantly more time and money to produce, essentially relegating the material to small-volume cars. The main benefit for trucks is the resulting reduction in weight to improve fuel economy without sacrificing the tough, rugged capabilities truck buyers expect. The Ford F-150 made the switch to aluminum for the 2015 model year and it's proved highly successful. It seemed like it was only a matter of time before the competition followed suit. Automotive News says that the next-gen trucks will launch with aluminum beds and that it will take a couple of years before we'll see any carbon fiber incorporated into the design. Even then, only look for the composite material on higher-trim models, with a trickle down to lower-spec trucks possible further in the future. In 2011, GM announced it was working with Japan-based Teijin Limited on a carbon fiber reinforced thermoplastic. There's a good chance that material's introduction will be on trucks.
