GM Announces Horsepower, Torque Ratings for 2014 Silverado and Sierra V-6 Engine
Compare these figures to the standard V-6 engines in the Ford F-150 (302 horsepower and 278 lb.-ft.), Ram 1500 (305 horsepower, 269 lb.-ft.), and the Toyota Tundra (270 horsepower and 278 lb.-ft.). GM claims the additional torque offered by its 4.3-liter V-6 engine is good for a 500-pound advantage in towing over Ford, and a 700-pound advantage over Ram. The Tundra tows up to 4,900 pounds, but this rating is measured according to SAE J2807 standards. Several years ago, all truck makers agreed to become compliant with this federal towing capacity standard, but to date, only Toyota has adopted the rule.
In addition to offering class-leading torque among normally aspirated V-6 engines, the new Silverado V-6 and Sierra V-6 are equipped with Active Fuel Management technology, which allows the engine to operate on 4 of its 6 cylinders under light-load driving conditions in order to conserve fuel. GM will announce official fuel-economy estimates for the new V-6 engine at a later date.
