GMC is looking to boost its Yukon portfolio with the addition of the new 2019 Yukon Graphite Edition and the 2019 Yukon Graphite Performance Edition, both coming to showrooms this summer, with pricing to be announced closer to their on-sale date.

The latter focuses more on performance, which is why it comes with a 420 HP 6.2-liter V8 engine, a 10-speed automatic gearbox, magnetic ride control and more.

In the Yukon Graphite Edition, you gain 22-inch bright machined wheels with Carbon Flash Metallic pockets, black assist steps with gloss black accents, a premium black chrome grille mesh insert and fog lamp surrounds, body-color grille surround, black roof rails, gloss black beltline moldings and some additional black trim.

Meanwhile, the Performance Edition enjoys 22-inch six-spoke gloss black wheels, Active two-speed transfer case (4WD models only), trailer brake controller, 170-amp alternator, 3.23 axle ratio, high capacity air cleaner, Bose active noise cancellation, multi-color HUD, 8-inch reconfigurable Driver Information Center and an 8-inch color touchscreen sat-nav/infotainment.

Both Graphite Edition models are offered in three exterior colors: Onyx Black, White Frost Tricoat and Dark Sky Metallic.
