A new Black Edition available on SLT includes 20-inch machined aluminum wheels with black accents, black grille insert and black surround, black headlamp and taillamp details, and black mirror caps, roof rails and additional exterior accents.
The 6-speed manual transmission has been axed. Previously only available with the 4-cylinder and 2-wheel drive, the stick is off of the order sheets. Must have been a last minute change since it is still reported on the EPA web site.
Updated Infotainment systems are easier to use and can be updated over the air. SLE, All Terrain, SLT and Denali models get a second microphone to help improve voice recognition. NSA reports, "much easier to hear perp's confessions."

A first: a turbocharged 2.7-liter 4-cylinder is optional. With 310 horsepower and 348 pound-feet of torque, its more powerful than the standard 4.3 V6. Curiously fuel mileage with the new engine peaks at only 20 city and 23 highway.
All of the engines have the ability to shut of cylinders to save fuel, while the 5.3 and 6.2 V8s can run on as few as two cylinders. SLE and higher trims have automatic start/stop to save fuel at traffic lights.
A 3.0-liter turbocharged diesel inline 6-cylinder will also be offered, with the potential to claim the fuel mileage crown and offer high towing weights.
The diesel engine and the 6.2 V8 both come with a ten-speed automatic transmission. The 2.7-liter 4-cylinder turbo and the 5.3 V8 offer 8-speed automatics. The 5.3 V8 comes standard with a 6-speed and it is the only transmission offered on the base 4.3 V6.
Maximum towing will be as high as 12,200 pounds.
The story within the story is the new MultiPro tailgate. Standard on SLT, Denali and the new AT4, it has a unique center section that folds independently and then has a third folding section that acts as a step. Shown here with an upcoming tailgate stereo accessory, it can act as a desk, a cutout to make reaching into the bed easier, a cargo stop and more.
Other available new features: heads-up display puts speed, navigation directions and other information on the windshield in full color; carbon-fiber composite cargo box brags of higher strength than steel and lighter weight than aluminum; Lane Change Alert; and Surround Vision in High Definition.

The Sierra Limited will be available with one engine, the 355-horsepower 5.3 V8; one transmission, the 6-speed automatic; and one body style, a Double Cab.
