There is no doubting that fuel economy has become an important factor in the highly competitive fullsize truck market, with the Ford F-150 EcoBoost V6 and Pentastar V6-powered Ram 1500 setting quite a precedent in recent years. Now it's General Motors' turn. The General has just announced that the new base V6 used in the 2014 Chevrolet Silverado and GMC Sierra 1500 models will return an EPA-estimated 18 mpg city and 24 mpg highway in two-wheel drive trim, regardless of cab configuration.

While these figures don't go so far as to earn GM any "best-in-class" fuel economy claims (thanks to the 25-mpg Ram 1500 HFE), this new 4.3L EcoTec3 V6 does edge the F-150 and Toyota Tundra while boasting best-in-class numbers for torque, payload and towing capacity among six-cylinder rivals. This all-new engine produces 285 horsepower and 305 pound-feet of torque, and it gives the 2014 Silverado and Sierra the highest towing rating among standard V6 models with a 7,200-pound towing capacity – besting the Ram by 700 pounds, the base F-150 by 1,100 pounds and coming within 200 pounds of the V8-powered Nissan Titan.

Silverado V6: Best-in-Class Capability, 24 mpg Highway

-Best torque, payload and towing of any standard V-6
-Unsurpassed city fuel economy for full-size pickups

DETROIT – The 2014 Silverado with the all-new 4.3L EcoTec3 V-6 – the most capable standard V-6 in any full-size pickup truck – will also be a segment leader in fuel economy, helping save customers money when they buy and when they drive.

EcoTec3 engine technology enables 2WD Silverados to match Ram HFE's 18 mpg city, while 4x4 Silverados achieve 17 mpg city, the best of any full-size pickup. EPA highway estimates are highly competitive: 22 mpg for 4x4 versions, and 24 mpg for 2WD models.

Reflecting Silverado's straightforward approach to performance and fuel economy, these EPA estimates are achieved without expensive add-ons and apply to all three cab configurations, regular cab, double cab, and crew cab.

Silverados equipped with the 4.3L V-6 also will be the most-capable trucks with standard V-6 engines, with the highest available payload rating of 2,108 pounds and the highest available towing rating of 7,200 pounds.

"Budget-conscious customers often buy V-6 pickups to do real work, and the 2014 Silverado with the 4.3L EcoTec3 V-6 will combine unmatched capability and excellent fuel economy with surprising levels of refinement," said Jeff Luke, executive chief engineer.

"Our V-6 has torque where you need it to get the job done, with 230 lb-ft of torque available at 1,200 rpm, and more torque available from 2,400 to 5,300 rpm than competitive V-6s make at their peak."

Truck customers now returning to the showroom will find that Silverado's standard V-6 now offers better performance than many V-8 powered pickups from just a few years ago, with far superior fuel economy.

"The average pickup on the road is more than 11 years old," said Luke. "Customers driving these trucks with V-8 engines will be amazed at the power and refinement of Silverado's new EcoTec3 V-6, which has fuel economy some 30 percent better than older V-8s with comparable performance."

The new V-6 joins the mainstream 5.3L EcoTec3 V-8, with EPA-estimated highway fuel economy of up to 23 mpg, the best estimates of any V-8 pickup, and better than estimates for the Ford EcoBoost turbo V-6 (22 mpg EPA highway for 2wd models).

Seamlessly switches to four-cylinder operation

Silverado's combination of capability and efficiency results in part from its EcoTec3 engines, which provide the proven power of a large-displacement truck engine when needed, then switch seamlessly to four-cylinder operation under lighter loads.

"In creating the 2014 Silverado 1500, we looked at a wide variety of powertrain configurations, and concluded that purpose-built truck engines could best provide the payload and towing capability that truck customers require with the long-term dependability they expect," said Luke.

By creating a new trio of EcoTec3 engines for the 2014 Silverado, Chevrolet was able to make the most of the size and performance of each entry:

-The 4.3L V-6 is a rugged and refined standard engine with best-in-class torque, payload and towing.
-The 5.3L V-8, expected to power three out of four Silverados, gives mainstream customers 355 horsepower, with fuel economy better than any V-8 competitor or Ford's EcoBoost turbo V-6.
-A new 6.2L V-8, available this fall, will be the most powerful engine offered on any light-duty pickup, with an estimated 420 horsepower and 450 lb-ft of torque, and a maximum available towing rating of 12,000 pounds.

All three EcoTec3 engines feature direct fuel injection, Active Fuel Management (cylinder deactivation) and continuously variable valve timing, a combination not found in competitive trucks. The engines also use a compact overhead valve design and weight-saving components such as aluminum blocks and cylinder heads to reduce the mass of the engines for additional energy savings.

2014 GMC Sierra V-6 Delivers 24 mpg Highway
Efficient engine is also most capable standard V-6 in class

DETROIT – The same technology that makes the all-new 2014 Sierra's 4.3L EcoTec3 V-6 the most capable standard V-6 in any full-size truck also makes it a segment leader in fuel economy, allowing owners to go farther on a single fill-up.

EcoTec3 engine technology enables 2WD 4.3L V-6 Sierra models to match Ram HFE's 18 mpg city, while 4x4 models achieve 17 mpg city, the best of any full-size pickup. EPA highway estimates are highly competitive: 22 mpg for 4x4 versions, and 24 mpg for 2WD models.

Sierras equipped with the 4.3L V-6 also will be the most capable trucks with standard V-6 engines, with highest available payload rating of 2,108 pounds and the highest-available towing rating of 7,200 pounds.

"The 2014 Sierra offers capability, efficiency and refinement regardless of trim level or engine choice," said Tony DiSalle, vice president of GMC Marketing. "All of the technology that makes this our most efficient half-ton pickup ever comes standard for every customer."

EcoTec3 technology is comprised of direct fuel injection, Active Fuel Management (cylinder deactivation) and continuously variable valve timing, a combination not found in competitive pickups. The engines also use a compact overhead valve design and weight-saving components such as aluminum blocks and cylinder heads to reduce the mass of the engines for additional energy savings.

      If they put this engine in the base work truck, they will sell millions. If they make the same mistake as Ram did, and make you buy the one with all of the bells and whistles, just to get the efficient engine, it will flop.

          I think that is just to offload the last of the old non-hemi v-8s. I'm sure that the v-6 will be the base engine once those motors are gone.

        In the past, a V6 mated to a four-speed auto was a terrible combination for a truck, you didn't save any fuel but you couldn't haul much more than a toolbox either. This is no longer the case; a modern V6 and transmission can easily handle the duties of a full-size pickup. Now the market is starting to respond. Ford is now seeing V6 engines quickly become the preferred engine choice for most buyers.

        A v6 is all most people need in a 1/2 ton pickup I do heating and cooling and tow a trailer and my 2008 f150 4.2 is good on power. I really like the numbers these new engines are putting out, about another three years I will have either a new ford or GM 6 cylinder in my driveway. Hell everyone want's a big v8 and I guarantee I work my trucks more than most people, and they have been very very durable and reliable.

      So you _might_ get 20 mpg combined. That's an improvement but still not much to brag about. I don't tow much other than a jetski, a half yard of dirt, or an ATV... but my 4 banger Ranger averages 28 mpg on a whole tank. 25 if I'm pulling stuff. I want a small truck that gets at least 30 mpg in the year 20-freaking-13.

        @A_Guy
        I find it hard to believe your Ranger fuel economy numbers. My unloaded regular cab 2wd 4 cyl. 5 speed manual Ranger typically gets around 22 mpg around town, maybe 25 mpg with mostly highway and that's driving conservatively and with summer fuel. As a test, I once got 31 mpg with almost all highway and with hypermiling techniques. In comparison the economy of the newest full size pickups are impressive.

          @ffforte
          I live in TX, if that helps. Mine is an 08. Before I lifted it, it was consistently 28 mpg on a tank with mixed driving (60 mile round trip to work in Austin). After the lift (and gear ratio change) I consistently get 26 mpg on a whole tank. I was comparing my non-lifted MPG numbers to this non lifted truck. The ranger 4 banger has been the same for over a decade - so I really don't find these mpg estimates that impressive, considering the time. I know its a little bit comparing apples and oranges, but I still have no reason to upgrade, when we're talking gas mileage.

        @A_Guy
        comparing a half ton truck to your ranger...... Um unless you had the 4.0 ranger i would not advise towing just about anything (same could be said with the 2.2 S10) and if you did have the 4.0 ranger no way you got 28mpg unless you never go over 45mph
          A_Guy
          • 1 Year Ago
          @Thipps
          Does it really matter if I compare this to my Ranger? The only point I am wanting to make is that the numbers aren't that impressive to me for what I use a truck for. They are incrementally better every few years and I constantly hear the argument that it's pointless to buy a small truck these days because you can get a full-size that gets the same gas mileage. But you can't and here I draw a comparison to what my truck's mpg is. I want to see better numbers all around, whether that means more engine options or more technology options (I'd look twice at a hybrid pick-up). That's all. :)

      I have to give props to Chevy for being so damn smart in bringing back this engine. I know push-rod engines get a lot of **** for being "old" technology, but the reality is that pushrods are perfect for truck applications. Trucks are one place where high RPM power is less valuable than low-end power. But, the major reason I think Chevy deserves props for this choice is cost. Dodge also puts pushrod engines in their trucks, but their V6 option is a quad-cam V6. The problem is that a pushrod V8 is cheaper to produce than a quad-cam V6. The effect of this is that their V6+8speed RAM is more expensive by $1000 than their V8+8speed RAM. This new 4.3 is going to allow Chevy to kill Ford and Dodge in the low-end truck market. Bravo Chevy. (I'd like to see Chevy spend that savings on a few snails.)

      That's nice and all, but outside of fleet buyers, who's gonna take the V6 over the 5.3L? According to the Sierra first drive Autoblog recently published: " In any case, the EPA estimates the 5.3-liter V8 (4WD) will achieve 16 city and 22 highway. We reset the trip computer and averaged 21 mpg during a 15-minute cruise on level highway at 70 mph. Out of curiosity, we also spent some time with the 4.3-liter V6 in a 4WD crew cab. For those who haven't been following too closely, this engine has been significantly upgraded from its predecessor. (Are we the only ones who can't stop thinking about the lethargic 165-horsepower "4300" under the hood of the 1985 Chevrolet Astro van?) Acceleration was good and the six handled the full-size truck nearly as effortlessly as the eight, but acceleration was down a tick or so to 60 mph. As of press time, fuel economy figures have not been released for the V6 engine. However, running the same route as we had with the V8 earlier in the day, we reset the trip computer and averaged 22 mpg during a similar 15-minute cruise on level highway at 70 mph. Considering how close the V6 and V8 seemed to be in real-world highway efficiency, and the fact that GMC only charges a petty $895 premium for the 5.3-liter, the V8 seems the no-brainer choice in the showroom, especially if the owner is among the 60 percent who will tow." Without any real world mpg or cost benefits, GM might as well only make the V6 available in rubber floor, crank window, no stereo, W/T trim.

        Just a point - stated another way, it's about 5% better fuel economy... 26 gallons or about $100 at 12,000 miles per year. Of course, part of the fuel economy increase will come from better stop-and-go mileage, something not reflected in 15-minutes of a steady 70-mph cruise.
