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.

Fords diesel is much more reliable than the international they had in the truck before. It's sucks your friend had a bad experience, but that purely anecdotal. Those engines were overbuilt and have been quite reliable and popular for good reason.

He actually has that diesel truck as well, and while just last week the turbo blew up and leaks oil, it's been more reliable than the new one.

It's ironic, because the new diesel had the same problem as the old one, IIRC. I say that because it is hard keeping up with all the different stories of why he doesn't have his newer super duty truck today. Once this past winter was his truck couldn't start; his new battery from the dealership crapped out within a year and was replaced under warranty.

Is he just beating the hell out of it? or not taking care of it? He may have a lemon but two in a row? My pops has a 250 and we tow a 5th wheel, car trailer and havent had any issues what so ever. Maybe he spent all the money on the truck and cant afford the gas! :D

He does brick work and construction, so to him some of it is normal for the heavy duty work he does with it.

Honestly, unless he needs the increased fuel economy or really heavy duty towing, the gas V8 is cheaper to operate. We only picked diesel because my wife was going to have to commute in it for a while and my friends with the Ford V10 were only getting 12 mpg in similar commutes. We got 16-17 with the diesel which, interestingly, was the exact same as our old 2004 Tundra.

I don't buy it. The only way your friend could have had such misfortune, is abuse and/or neglect of the vehicle. Brand new batteries don't just "die" for no reason. He left an interior light on, or some other accessory. Rather than own up to his mistake, he blames the product for being faulty.

It's a common occurrence. People who crash their cars frequently blame it on fictional mechanical problems (unintended acceleration, anyone?) rather than own up to their incompetence.

Pro Tip: Don't ever let your friend borrow your car, unless you want to see it develop mysterious unexplainable failures as well.

The dealer diagnosed it as bad because it couldn't produce enough cca, not due to a mistake of leaving on a light.

The truck is used for actual work. He expects it to work without issues for more than 2 months after having literally a new engine put in.

Ford does have a known issue with the Superduty trucks. For some reason the twin battery system on the diesels will sometimes fail to charge one or both of the batteries. Or one battery will drain a bit and then the other will drain trying to balance it. Other times it has been pinned on the control unit built into the alternator Ford uses.

No knows why for sure but the Forums over on are rife with these issues. It has been an ongoing issue at least since the transition to the new body style back in 99'. It's not every truck but it happens, albeit infrequently.

Either way trying to start a large diesel with under performing batteries in the cold is a real pain in the a**.

Manch, you should tell your friend to use the built in block heater, it puts less strain on the batteries trying to start in the cold.

As for blowing the engine Me thinks something else is afoot.

I don't know man...if you read the reliability reports out there (at least for the F250 SuperDuty) you don't find a clean record...

I have a couple buddies who have owned that series, and one is regretting that he still owns his (2009). Nothing but problems. He's also a "car guy" who's main hobby is working on vehicles - favorite being the Mustang - and works as a Transmission specialist in a Call Center for a supplier for Ford...So I tend to listen to his advice..

Still, this story and thread is talking about the Big 3 mostly...and I refuse to own one...If I had a need for a large truck, the Tundra would be on the top of my list :)

Typical internet mixing and matching of engines and drivetrains and calling it all the same thing. The old 6.0L V8 had some problems early in it's life that were taken care of by the end of 2005 but the ignorant police keep perpetuating those problems into entirely different drivetrains. There are literally millions of Ford trucks on the roads and if they were really pieces of junk, Ford would NOT be able to keep the number one selling spot for 30 years straight without fail. Seriously, think about that for a second. How many 6.0L diesel commercial vehicles do you see on the roads STILL to this day when Ford has moved onto two different engines since?
