details released on new chevy/GM truck engines
http://www.autoblog.com/2013/04/01/2...better-econom/
bottom line, 2014 Silverado 1500 with its 5.3-liter EcoTec3 V8 gets 355 horsepower and 383 pound-feet of torque. EPA rating of 16/23/19 which is better than the ecoboost albeit with less power.
The GM press release specifically mentions the Ford ecoboost and compares it's V8 to it. All three GM EcoTec engines feature direct fuel injection, Active Fuel Management (cylinder deactivation) and continuously variable valve timing.

Yawn......I've got a smaller engine, more HP, more torque and better MPG's. I'm already averaging 23-25 MPG on the highway and I'll pass on the cylinder deactivation

You don't have better mileage actually. Those numbers are US gallons and I assume you are talking Canadian. The GM EPA rating is higher than the ecoboost albeit very marginally. Now in the real world, we shall see. As we've learned from the EB, the EPA ratings don't tell the whole story.

They should be comparing that to the 5.0 not the Ecoboost. I'm assuming it has the same torque curve as the 5.0 as well... Nice try Government Motors.. I do think it's funny that they raised the max tow capacity just high enough to beat Ford.

I'm going by what the truck computer is saying. I switched the units from metric to english and I'm getting 23-25 MPG.

Not impressed. Less HP & TRQ for 1 mpg.... 
Also big effing deal GM on the 200 lbs over ford for towing with arbitrary number. Line both of them up on Davis Dam & then lets see. Plus all the extra problems of a new body & a new powertrain in the same year. Uh no thanks.
GM is still playing catch up to the F150. Even if there truck performs as advertised they are saying their brand new design is as good as the Ford.
And the Ford body is 5 years old with the engine being 4 years old. (Was used on the Flex & Taurus 1st). So GM good luck when the gen 13 F150 comes out if your new truck is comparable with the "old" Ford truck.

cyclinder deactivation, heck no, i dont need to feel the cam shudder, i got Honda Odessey with that deactivation and if honda cant perfect it theres no way i am gonna trust Govt Motors. I'll pass but i am sure the Chevy Guys will be high fiving each other.
