GM bests Ford's EcoBoost V6 fuel efficiency without complex, expensive turbochargers

Ford has spent a great deal of time and money developing and marketing its EcoBoost family. The company makes a wide variety of EcoBoost engines (which is basically a fancy name for turbocharging plus direct injection) ranging from a 1.0-liter three-cylinder to a 3.5-liter V6.
 
Ford's efforts have paid off, as sales of the naturally aspirated V6- and EcoBoost V6-equipped F-150s have outpaced those of the V8 models. And all along the way, Ford has thumbed its nose at the Chevrolet Silverado/GMC Sierra, stating how its EcoBoost V6 gets V8 performance and V6 fuel economy.
 
GM, however, is hitting back today with the announcement that its new 5.3-liter EcoTec3 V8 engines manages to produce 355 horsepower and 383 lb-ft of torque. While the horsepower number compares favorably with the EcoBoost V6 in the F-150, it's down quite a bit in torque. GM says that in 4x2 trim, the EcoTec3 will be good for 23 mpg highway; checking off the 4x4 option box will result in 22 mpg on the highway.

Both of these numbers are 1 mpg better than the EcoBoost F-150. In fact, it matches the fuel economy of Ford’s naturally aspirated, 3.7-liter V6.
 
“Silverado’s available 5.3-liter EcoTec3 V8 gives customers the best of both worlds,” bragged Jeff Luke, executive chief engineer for the Silverado. “Customers get the proven power and dependability of a V-8 truck engine, with better fuel economy than a leading competitor’s smaller turbocharged V-6.”

GM's decision to go the "tried and true" route may pay off in the end. Recent reports have suggested that while many manufacturers seem to ace the EPA's tests with turbocharged gasoline engines, most consumers aren't able to match the sticker numbers in the real world.

GM’s fun in the mpg sun, however, likely won’t last long. Ford is reportedly looking to trim up to 700 pounds from the next generation F-150, which will go a long way towards improving fuel efficiency. Ford showcased the use of active aero technology on its Atlas truck concept (which no doubt is a precursor to the next generation F-150), which boost highway fuel efficiency by 2 mpg.

You do not understand it, ok hows this:
People buy trucks for the purpose they are designed for: towing and cargo. It is that simple. Manufacturers are now understanding that truck buyers will always be truck buyers so they may as well improve their fuel economy.

Just because they may not use it to tow or haul cargo every single day or even every week does not mean they should not own a truck or are an idiot as you claim. If anything they are the smarter buyers. Much smarter than these real idiots in a 4 cylinder Ford Escape towing a 3000 pound camper, then wonder why they have trouble stopping or get into a wreck with it. Oh but hey at least they get good gas mileage huh?

Every vehicle segment has its purpose. Not everyone will buy an appropriate vehicle for their needs. Some may buy a truck just because they like them and never haul cargo or tow anything, when a 4cyl car will do just fine.

Here in reality land, a majority of us buy the vehicle that suits our need whether its 15mpg city SUV/truck or a 50mpg car.
