- butt weight, the airs mower!I think that's a wise choice. I mean, adding more variety to the market. Ford can keep its Ecoboost V6s and dodge with the diesels. It will be an interesting competition.
ECO-BOOST VS ECO-TECH3
We’ve got more information about GM’s new full-size pick-ups. The new Chevrolet Silverado and GMC Sierra are rated at 23 miles per gallon on the highway with the new 5.3 liter V-8. That’s better than Ford’s EcoBoost V-6. In fact, Chevy now refers to its pickup engines as Eco-Tech3. The increase in mpg’s comes mainly from direct injection, cylinder deactivation and variable cam timing. Amazingly, GM achieved this improvement with a 6-speed automatic. Look for an 8-speed later that will bump these numbers even higher. Also, GM claims these trucks are 200 pounds lighter than an F-150. Best of all, the new Silverado and Sierra will start at the same price as the models they’re replacing, despite having a lot more new equipment. We’ll be reporting a lot more on these trucks as the details become available.
