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.

Some people on here are like those in graphics cards debates of AMD vs Nvidia, Seriously stop the bragging. It's a car it is made by people just like you and me at some plant around the globe, Guess what they all have recalls from time to time get used to it. Recently it was Toyota and Honda, Lately it was Mazda with some safety issue, You people buy imports think it's better cause of the badge? ridiculous. As for Ford and GM, Get one that does the job for you, Worrying about which has a lower exhaust temperature? Are you fkn serious? How does that matter in real world. People bag the shit out of Holdens over here where I am yet I thrash the crap out of my V8 and it still keeps going and going and going, I see all these newer turbos broken down on the side of the road. It's all great going to a smaller engine and turbo charging but really all it's doing is making the engine work harder which will wear it out quicker. I see a crap load of older V8's on the road some are rusted out but still drive, I don't see a lot of older 4cylinder turbos on the road. Sure you can get the same or more power out of smaller turbo engine but it has to work twice as hard to make that same power, You will soon learn about it from your wallet later on. The old Push rod tech still has some life in it yet, Cheap and powerful,reliable and so easy to mod. Just buy a car for the look/features and stop worrying about 1mpg more than some competitors for fucks sake, It's not even a Mc Donald's meal worth of fuel savings.
