The GMC Sierra was all-new for 2014, and its bold new styling, new engines and radical interior makeover turn the Sierra into a standout on the road and a 5-Year Cost to Own champ. It shares most everything -- except exterior styling -- with its corporate cousin the Chevrolet Silverado. But that style makes a big difference, as the Sierra's appeal is more upscale than that of the workaday Silverado.
The Sierra comes with a choice of three engines: a 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8. All three use cylinder deactivation, direct injection and continuously variable valve timing, plus a 6-speed automatic (8-speed with the 6.2-liter V8) transmission, to improve fuel economy. That work paid off, as the Sierra currently boasts the best fuel economy for a V8 in its class.
The Sierra is designed for work, with its Regular Cab capable of towing as much as 7,600 pounds with the V6 and 9,800 pounds with the 5.3-liter V8 when properly equipped. Features that make it easier to line up the truck with a trailer are available, and the CornerStep rear bumper helps when getting gear into and out of the bed. Yet despite the Sierra's capable nature, the interior is one of the quietest in its class and is available with easy-to-use navigation and infotainment systems.
When it comes to the long-run cost, the 2015 GMC Sierra 1500 Regular Cab Work Truck is best in its segment, with an estimated $42,881 expenditure over five years.
