It's the information everyone's been waiting for. General Motors just released pricing, power, and fuel-economy figures for the 2014 GMC Sierra equipped with the new EcoTec3 fifth-generation small-block 5.3-liter V-8 with direct injection. GM's new bread-and-butter full-size engine is rated at 355 hp and 383 lb-ft of torque. For those who are counting, that's 10 hp and 37 less horsepower than Ford's 3.5-liter EcoBoost V-6. But perhaps even more important than its arguably negligible power deficit, is that it achieves 1 mpg better on the highway than the Ford in its EPA rating on both two and four-wheel-drive models, as well as matching or exceeding the F-150 on towing capacity as well, with a maximum tow rating of 11,500 pounds equipped with the 5.3, and a maximum payload of 2102 pounds.
This is a major marketing coup for GM, and one it will likely play to the hilt in its advertising and promotional campaigns for the new trucks. Although the EcoBoost has proved very popular among truck buyers, there is still a segment of full-size truck owners and potential buyers that is somewhat skeptical about the long-term durability and reliability of a turbocharged V-6 in a truck application, and GM is hoping to capitalize on that with the new 5.3's competitive power and fuel economy figures relative to the EcoBoost.
In addition to the power and fuel economy figures for the new Sierra, GM also announced base prices for the 2014 Sierra 1500. The regular-cab model starts at $25,085, the double-cab goes for $29,110, and the Crew Cab starting at $33,210, including destination. For the first time in a GM full-size, the Crew Cab 4x4 is available with a V-6, a testament to GM's confidence in the base engine's power output and driveability. Power or fuel economy figures have not yet been announced for the base 4.3-liter V-6 or topline 6.2-liter V-8, both of which also employ direct-injection, like the 5.3-liter V-8.
The mileage benchmark for the base V-6 has been set by the new Ram 1500 with the Pentastar V-6 and eight-speed automatic, which achieves up to 18 mpg city and 25 mpg highway in its most economical trim. GM's trucks are launching with six-speed automatics, but may get eight-speeds farther down the road. Ram just last week also announced fuel economy figures for its Ram 1500 4x4 with the Hemi and eight-speed, giving it an EPA rating of 15/21, matching the F-150 2WD with the 5.0-liter V-8, and giving it a 1 mpg city and 2 mpg highway edge over the F-150 4x4 with the 5.0 engine.
