General Motors announced today that the base engine in the 2014 Silverado and 2014 Sierra pickup trucks — the all-new 4.3L EcoTec V6 — has the most torque of any standard (read: base) V6 in the segment: the six-banger makes 305 lb.-ft. (413 Nm) and SAE-rated 285 horsepower (212 kW).
Torque, the turning force that generated off-the-line acceleration and delivers confident trailering performance, is a characteristic of a truck engine that is usually more desirable in trucks than horsepower. And the Silverados and Sierras equipped with the 4.3L V6 EcoTec3 will have trailering ratings of up to 7,200 pounds (3,266 kg) for a regular cab, short bed, four-wheel-drive model, which is 500 pounds more than the most capable Ford F-150 (with the 3.7L V6) and 700 pounds more than a Ram 1500 (with the 3.6L V6). No fuel economy numbers were released for the 4.3L Ecotec3 V6 yet, but GM did say that it will release estimates later.
The entire EcoTec3 engine family, including the 5.3L V8 (that will first be available at launch) as well as the 4.3L V6 and 6.2L V8 (that will be available later this year) has been designed specifically for the high trailering and hauling demands unique to truck buyers. The three engines will be mated to a proven and efficient six-speed automatic transmission (at least for the first year of availability).
In addition, the Ecotec3 engine family features three state-of-the-art technologies, including direct injection, active fuel management (cylinder deactivation), and continuously variable valve timing. These features have been proven and perfected through 6 million hours of computational analysis by engineers studying the combustion process, while a total of 10 million CPU hours were spent refining and making the most of the Silverado’s and Sierra’s EcoTec3 powerplants.
The best-in-class performance of the 4.3L EcoTec3 V6 joins that of the 5.3L EcoTec3 V8 — which also features best-in-class towing.
2014 Silverado and Sierra models with the 4.3L EcoTec3 V6 will go on sale later this year. The Silverado will have a suggested starting price of $24,585, while the Sierra will start at $25,085. Both prices include a destination charge of $995 but exclude tax, title, license and dealer fees.
