2018 GMC Sierra

Pros: Expansive passenger and cargo room; well-designed technology features; broad range of models, body configurations, and powertrains to choose from

Cons: Prices rise quickly as options are added; ride comfort doesn’t quite match Ram 1500—it’s a bit jiggly over rough pavement

CG Says: For 2018, the GMC Sierra’s eAssist hybrid system is available nationwide. Previously, eAssist was only available in California. Sometimes called a “mild” hybrid, eAssist provides additional torque during acceleration via a motor/alternator/generator located on the gasoline engine itself. The eAssist system will not propel the vehicle on electric power alone, but it does provide automatic stop/start capability–and some extra power. All Sierra models now have a standard rearview camera and the tire-pressure monitor now has an audible tire-fill alert. The Sierra is a full size pickup with a choice of three engines: a 285-horsepower 4.3-liter V6, a 355-hp 5.3-liter V8, or a 420-hp 6.2-liter V8. The V6 is paired with a 6-speed automatic transmission. The 5.3-liter V8 has a 6-speed automatic or an 8-speed automatic, depending on model. eAssist is added to the 5.3-liter V8 and has an 8-speed automatic. The 6.2-liter V8 also is paired with the 8-speed automatic. Rear-wheel drive is standard and full-time 4-wheel drive is available. Available features include forward collision alert, low-speed emergency automatic braking, lane-keep assist, adjustable Magnetic Ride Control System, hill-descent control, locking rear differential, rear-seat entertainment system, wireless charging pad, heated/ventilated front seats, and heated steering wheel. The GMC Sierra stacks up well against class rivals, and—like its Chevrolet Silverado sibling—offers strong, refined engines, good on-road behavior, plenty of handy in-cabin storage, and an impressively quiet driving environment; top-line models such as the Denali add a healthy dose of luxury to the mix. Sierra lags the Ram 1500 in handling and ride quality (as do all other full-size pickups), but it’s still a Best Buy in this class.
