GMC has completely redesigned the Sierra 1500 series pickup for 2014, producing the most powerful, most advanced and most refined full-size pickup in the company’s 111-year history.

Like its Chevrolet Silverado cousin, the 2014 Sierra is available in three new EcoTec3 engine choices, as well as regular cab, double cab and crew cab body styles. As always, buyers have their choice of rear- or four-wheel drive configurations.

Additionally, the 2014 Sierra is available with a 5-feet, 8-inch; a 6-feet, 6-inch; or 8-feet bed length.

The 2014 model trim levels include Sierra, SLE, SLT and the premium Sierra Denali.

The base powerplant features an all-new 4.3-liter V-6 engine that delivers 285 horsepower and 305 lbs.-ft torque.

Sierra buyers also have the option of two available V-8 engines: a new 5.3-liter V-8 that delivers 355 horsepower and 383 lbs.-ft. torque; and a 6.2-liter V-8 that produces 420 horsepower and 450 lbs.-ft. torque.

All three engines require regular unleaded gasoline or E85 and are mated to a six-speed automatic transmission.

The 2014 Sierra is one of the most well equipped, premium pickups on the market — especially the Sierra Denali.

A lot of attention to detail has been paid to the cabin, which features premium materials throughout the interior.

I really appreciated the fact that all of the knobs and buttons are large, easy to see and easy to reach and use — even when wearing work gloves.

Without question, the Sierra is one of the most capable work trucks on the planet, but it’s also very refined — and loaded with technology.

The new Sierra is available with GM’s IntelliLink connectivity, which uses a high-definition, fully reconfigurable eight-inch color touch screen with an intuitive layout and easy-to-read icons that controls audio features, a Pandora app, Bluetooth phone features and available navigation with all-new map displays.

Many of the system’s features can be controlled by voice command, allowing drivers to keep their eyes on the road and hands on the wheel.

Also, for the first time on double cab models, the 2014 Sierra has new front-hinged rear doors with outside pull handles at the rear, providing improved access in tight parking spaces. Unlike trucks with rear-hinged doors, Sierra’s layout allows rear passengers to enter and exit the vehicle with the front doors remaining closed.

There have also been several innovations to the cargo box. The rear bumper features standard corner steps that make climbing into the bed easy, regardless of whether the tailgate is up or down. Also, four movable upper tie downs are now standard that can be placed in nine different locations.
