Ford was seen as taking a big gamble when it reintroduced V6 engines into its full-size pickup trucks. But the gamble has paid off and now the Blue Oval’s domestic rivals will look to do the same.

With plans for the Ram 1500 to get Chrysler’s new Pentastar V6 engine, look for GM’s Silverado and Sierra twins to offer a V6 option as well.

While also looking to develop the 5.3-liter V8 used in the current rucks, GM is also said to be planning a twin-turbo 3.0-liter V6 engine that could be offered in everything from Cadillac models to trucks, as part of the automaker’s plan to cut the number of engines and platforms in half.

Currently, the GM 5.3-liter V8 comes close to the fuel economy of the Ford EcoBoost engine, although power is down somewhat with the 5.3L making 315 hp and 335 pounds-feet of torque, compared to 365-hp and 420 lb-ft in the Ford. The smaller-displacement GM V6 turbo might have trouble laying own the same numbers as the Ford engine, but should handily beat it in fuel economy.

Look for GM’s new Chevy Silverado and GMC Sierra trucks to arrive with this new engine, plus a lower curb weight and the possible use of an 8-speed automatic transmission in 2013.
