2014 Chevrolet Silverado 1500

General Motors unveiled its fully redesigned 2014 Chevrolet Silverado 1500 and GMC Sierra 1500 on Thursday. The two trucks are mechanically similar, with the same platform and similar powertrains. However GM North American President Mark Reuss says in a press release that “The new Sierra and Silverado are more differentiated than ever in unique features and materials, in their standard content and in their design and details.”

The new trucks are available with three all-new engines. According to the press release on the Silverado, the new engines all feature cylinder deactivation, direct injection and variable valve timing. The engines are the same size as those in the current model, however, with a 4.3-liter V6 and V8s that displace 5.3- and 6.2 liters. Chevrolet says that horsepower ratings and fuel economy figures will be released next year, but that the engines will be more powerful and more fuel-efficient than the current ones. A six-speed automatic transmission  routes power to the wheels. Both two- and four-wheel drive are available.

2014 Silverado 1500 Extended Cab

Extended cab models now have traditional forward-hinged doors rather than rear-hinged suicide doors found on current models. This move follows in the footsteps of the Ram 1500 and Toyota Tundra. The crew cab model is now available with a 6-foot-6-inch bed, as it was previously available with only the shortest 5-foot-8-inch bed. Until now, the only full-size half-ton pickups to offer this configuration were the Ford F-150 and Nissan Titan. Chevy and GMC have integrated step cutouts into the corners of the rear bumper to make it easier to climb into the bed, rivaling Ford’s tailgate step.

Car and Driver says that while the new trucks may not appear dramatically different from the models they replace, that could be okay. “The outgoing model is fairly handsome, and recent updates to the Silverado’s key domestic competitors—the 2013 Ram 1500 and the Ford F-150—haven’t delivered radical stylistic changes, either.”

The trucks’ interiors are also completely overhauled, and PickupTrucks.com is pleased with the changes. Of the Sierra’s cab, they say that everything looks “more like a high-fashion magazine living room than a truck space.”

The new trucks are available with GM’s infotainment system (MyLink in Silverado, IntelliLink in Sierra) which features a reconfigurable 8-inch touchscreen, Bluetooth, Pandora, navigation and voice command recognition. This system competes with MyFord Touch and Uconnect, found in Ford and Ram trucks, respectively.

Both trucks come standard with trailer sway control and hill-start assist. Both are also available with GM’s vibrating safety alert seat, which vibrates when the truck senses a crash may occur. Forward collision alert, lane departure warning and parking sensors are available as options. While trailer sway control, hill start assist and parking sensors are available on most full-size pickup trucks, the optional safety features are segment exclusive – for now.

Pricing for the new trucks hasn’t yet been announced. The 2013 Silverado 1500 starts at $23,590 and goes beyond $43,000 for a fully-loaded model, with the Sierra following a similar, slightly more expensive pricing structure. Currently, the Silverado and Sierra 1500 rank third and fourth in our rankings, respectively. As reviewers spend time in the new trucks, we’ll analyze their reviews and update our scores, so the rankings may change.
