For the first time ever, GMC will offer a luxury-laden Denali variant of its hauler-friendly Sierra HD pickup range. The truck unit of General Motors will now offer a Denali version on all but one of its mainstream consumer offerings.
Set to go on sale in early summer, the Sierra Denali Heavy Duty will come standard with the automaker’s 6.0-liter Vortec gasoline V8 engine but will offer the new 6.6-liter Duramax turbodiesel that debuted recently in the Silverado HD.
That diesel V8 cranks out a solid 397 horsepower and 765 lb-ft. of torque at just 1,600 rpm and comes mated to a new six-speed Allison automatic transmission. Capable of running on B20 biodiesel, the big V8 can propel the Sierra Denali HD to 60 mph in less than 9 seconds and can tow a maximum of 15,600 lbs. with a fifth-wheel hitch.
To set the Denali apart from the standard Sierra Heavy Duty, the truck gets a unique four-bar chrome grille, chrome exterior door handles and accents and a choice of 18 or 20-inch chrome alloy wheels. Three colors will be on offer: Black, Stealth Gray and White.
Inside, the Sierra Denali HD gets the standard Denali tricks – look for unique brushed aluminum trim, upgraded leather seats and a whole host of standard equipment.
The Sierra Denali HD debuts today at the Work Truck Show in St. Louis.
