The GMC Sierra Pickup - More Options and Great Fuel Economy

The GMC Sierra is the sister truck to the Chevy Silverado. While in many ways, it is very similar to the Silverado, when it comes to model choices, Sierra wins hands down. It has far more options available to the consumer than its sibling Chevrolet, and is a great choice for those who want to customize their truck to suit their exact needs.

Available Sierra Models - It's All About Choices

Whether you need a truck to commute, pull a trailer, drive the family, or haul lumber, Sierra's got you covered. Sierra's seven model options are: Work Truck (WT), SL, SLE, XFE, SLT, Denali, and the best in class mileage champ, Sierra Hybrid. This covers every need from a base truck to luxury hauler and everything in-between. Besides seven model choices, there are three cab choices as well - Regular cab, extended cab and crew cab. The two model choices on the regular cab are either the WT or the SLE. The extended cab is available as a WT, SL, SLE, or SLT. All seven models are available in the crew cab. As with most other domestic trucks, Sierra is available as a 1/2 ton, 3/4 ton or a 1 ton. This translates to your choice of a 1500, a 2500HD, a 3500HD - SRW (single rear wheel), or DRW (dual rear wheel). Now, what box length will fit your needs? There are three box lengths or bed choices: 5.5 feet, 6.5 feet and a long box, or 8' bed. Naturally, not all box lengths are available on all models.

Sierra Fuel Economy

When it comes to "best in class" fuel economy, the big story is the Sierra Hybrid. The Hybrid delivers a 33% improvement when compared to similar "non-hybrid" models with a 6,100 pound trailering capacity. This holds true for the 2011 Sierra Hybrid as well. Both 2011 and 2015 Hybrids earned an EPA estimate of 20 city and 23 Highway for either the 2WD, or 4WD models. This was accomplished by using the Vortec 6.0L engine with Variable Valve Timing (VVT) and Active Fuel Management (AFM), which, depending on power demands, shuts four of the eight cylinders down during light loads, or steady speed, level grade operation. Couple this with GM's advanced Electrically Variable Transmission or (EVT) and the trucks' 300 volt, nickel-metal hydride energy storage system that enables the Hybrid to accelerate and drive up to 30 mph, purely on electricity!

Another Sierra Model with notable highway mileage is the XFE, which incorporates several aerodynamic enhancements over the other models. It also takes advantage of an aluminum block, 5.3 Vortec V-8, coupled with a 6 speed automatic transmission and low rolling resistance tires mounted on 17" aluminum wheels. This combination provides owners with an EPA estimate of 15 city and 22 highway. Not bad for a full size, domestic pickup with a 7000 pound trailering capacity!

Sierra's New and Enhanced Features

For 2015, there's a new three bar, chrome grille on the SLE and SLT models. An electronic trailer sway control with "hill start assist" is incorporated with StabiliTrak. A spare wheel lock is standard on all models and cruise control is now standard on the base Work Truck. Touch screen Navigation including CD/DVD & MP3 playback with a USB port is available on SLT and Denali as is the Rear Seat Entertainment system with LCD display. Bluetooth cell phone connectivity is standard on SLT and Denali, and available on all other models. On Denali, other new standard features include heated and cooled seats, heated, leather wrapped steering wheel and a rearview camera.

Brief History of GMC and Sierra

GMC Trucks actually began as the Rapid Motor Vehicle Company in 1901. They developed some of the earliest one-cylinder engine, commercial trucks. The company was purchased by General Motors in 1909, which was the birth of the General Motors Truck Company, which is how "GMC" Truck came to be.

In 1975, the Sierra nomenclature became widely known when GMC began distinguishing its four trim levels as Sierra, Sierra Grande, High Sierra and Sierra Classic.
