3.5-liter EcoBoost V6

5.0-liter V8
All-new engine lineup boost overall fuel efficiency for Ford's top seller

Ford's F-150 is the best selling vehicle in America and has been for the past three decades. Thus, any big changes that effect the fuel efficiency of Ford's massive full-size trucks has an impact on hundreds of thousands of drivers' wallets each year.

Thus is the case with the powertrain lineup for the 2011 F-150. With looming CAFE regulations requiring drastically improved fuel efficiency from both cars and trucks, Ford is jumping the gun with an all-new engine lineup consisting of two V6 engines (one naturally aspirated, one turbocharged) and two V8 engines. To those that follow the auto industry, most of these engines should sound familiar to you.

The new base 3.7-liter V6 is used in a variety of Ford vehicles (Mustang, Lincoln MKX, Lincoln MKT) and produces 300 hp @ 6,500 rpm and 275 lb-ft of torque @ 4,500 rpm (max towing capacity 6,100 pounds) when used in the F-150.

The new 5.0-liter V8 first showed up in the 2011 Mustang GT, but is now making its way to the F-150. Naturally, the engine has been upgraded to handle heavy loads and manages to generate 360 hp @ 5,500 rpm and 380 lb-ft @ 4,250 rpm (max towing capacity 9,800 pounds).

The 6.2-liter V8 has already seen duty in the 2010 F-150 SVT Raptor, but is now filtering its way down to the rest of the lineup. The engine develops 411 hp @ 5,500 rpm and 434 lb-ft @ 4,500 (max tow capacity 11,300).

The last new engine is the wonderful 3.5-liter EcoBoost V6 that is used in the Taurus SHO and Flex. Ford is not giving official power/torque ratings for this engine yet, but it generates 365 hp @ 5,500 rpm and 350 lb-ft @ 1,500 rpm in the Taurus SHO. Best of all, the engine runs on regular unleaded.

According to the Detroit News, the EcoBoost engine will be a a step above the 5.0-liter V8 in price and will equal the towing capacity of the 6.2-liter V8 engine option.

According to Ford, with these new engines and standard six-speed automatic transmissions across the board, fuel economy will be increased by at least 20 percent compared to comparable 2010 F-150 models. The Detroit News also says that some models may achieve 24 mpg.

“Truck customers demand an engine that delivers outstanding low-speed torque to help tow or move heavy payloads, and sustained high-load, low-speed operation is a key attribute they look for,” said Barb Samardzich, vice president of Powertrain Engineering. “The engine lineup for the 2011 Ford F-150 has been tuned specifically for truck operation needs and optimized for fuel economy. The result is a lineup that delivers class-leading towing and payload capability with outstanding horsepower, torque and fuel economy.”

I was hoping Ford wouldn't castrate the engine with an artificially low towing capacity. And with the "new" max towing and payload options, you almost have no need for a 3/4 ton truck. 20 mpg while towing anyone?

Yeah, I just let that one go. But it does raise a credibility issue. Also, 20 mpg on a Tacoma WHILE towing. Hmmm. My friend with his very short, all freeway commute gets 20 mpg. The drag of a trailer and the extra weight act against good gas mileage. My guess, if you really did tow a 9800 lb trailer, would be closer to 12 mpg. My old 2004 Tundra, which has similar power to the newer Tacoma's, got 8-12 mpg while towing a 7800 lb trailer.

I was able to get 24mpg going from LA to Phoenix at 65-70mph. I have a deck lid on my bed that probably gives me a little better highway fuel economy. Typically mixed driving I get 18 or 19mpg depending if its winter or summer fuel.

You might find it strange, but aerodynamically it's been found through wind-tunnel and LES modelling that the standard pick-up truck has less drag with the bed open, tailgate up.

Nope, mythbusters did not test with a cover over the bed did they? Also, they did not test both long and short bed trucks and MOST of all they made a fatal error in their experiment -

They did not do two IMPORTANT things.

1) Run both trucks with the tailgate up to confirm rather than assume they would get identical mileage.

2) Repeat the test with the opposite tailgate position on each truck to confirm the difference in mileage was reproducible.

I agree with a prior post though, that people who have covers on their beds often tend to have things in the bed which could create more drag and change the results, even for the worse if the gate were down but it would not be wise to leave the gate down if something can potentially slide out onto the road even if the opposite were true and it helped mileage.

The 2005 Tacoma got a brand new power train so it doesn't really relate to you Tundra. Err I think, did the 2004 4runner get the 4 liter?

In 2005, it did. Made similar power and torque (245hp/282 lb-ft compared to 240hp/300 lb-ft). But it was lighter so it's a wash IMO. It also had about the same tow rating. I see the new one's make less power/torque (new rating method) and the tow rating was substantially reduced.

20mpg on a Tacoma is plausible if he's cruising at a constant speed and the trailer doesn't add too much drag. How much it weighs doesn't matter when cruising .

What's Newton's first law? A body in motion remains in motion unless acted on by an outside force. The only thing slowing down the truck would be the force of the air, so the truck only has to work hard enough to overcome the aerodynamics.

So yes, at a constant speed 20mpg is plausible.

City driving with a 9800lb trailer he would be getting single digit mileage.

At speeds under 40 MPH, the road friction causes a greater amount of friction than that of the air drag, so weight does play a significant factor depending on the tire size, pressure etc.

The point is, that it is still significant.

By that reasoning the vehicle and trailer would be in perpetual motion on a highway on the moon. There is friction in the wheel bearings and rolling friction to overcome, which increases by adding weight and a new axle to the equation. Also there is friction in the drive train even if you have transmission in neutral. Granted at 70 mph 80-90% of drag is probably aerodynamic.

FWIW, trailer tires (u-haul, campers, travel trailers, horse trailers, that trailer the lawn guy uses, etc.) are rated at 65 mph. Any time you see someone driving down the road faster than 65 mph while towing, they are at risk of serious tire failure. Even more so in warmer temperatures.

Yep and I see people bitchin all the time about how their cheap Chinese tires blew up all of a sudden on their trailers but they NEVER say how fast they were going, if they had the proper tire pressure, or whether they even check the tires regularly to make sure they're in good shape. We have some of those supposedly dangerous Chinese tires on our horse trailer, had them for 5 years now, and they're JUST now needing replacement.

We don't go barreling down the freeway at speeds well over the tires limits, we keep them inflated at the manufacturers recommended tire pressure and check to make sure they're in good shape.

Maybe that was once the case but today you can buy trailer tires rated for 100MPH. For example Kumho 857 et al... they just aren't the little trailer tires.

I love Ford trucks though. And now am the proud owner of a 90 F-250 with a 7.5L and it gets around 16mpg On the highway. Not sure about towing mpg though.
I tow a 9500 lb 5th wheel and get 12-14 mpg, depending on how many hills I have to climb. 2006 F250 diesel. We get 16 mpg on her commute and 20-22 on freeway driving.

Arg, I may come off as sounding like an asshat. I believe I was about 9000lbs total gross weight, including my truck and trailer together. I think it put the trailer around 6000lbs. Sorry.

And yes, I meant 90mph, not mpg.

I found it odd, that the truck averaged 18-22mpg, no matter how I drove it. 18mpg was the worst I ever got, and 22mpg was the best running premium fuel, and slowly accelerating, etc.

For that, I just drove how I wanted it.

Premium fuel? What does that have to do with fuel efficiency? :)


RE: Yes!!!

Why don't you tell me?

I do not know the exact science, but I believe higher octane is recommended for use in engines with vvti, and allows for greater compression in the engine, and improved fuel economy. If lower octane is used, the care adjusts the timing if it senses knocking in the engine, resulting in lower fuel efficiency.

But I may not be understanding it correctly.

Higher octane gas doesn't improve fuel efficiency. The higher the octane, the more knock resistance you get. You don't get anymore power nor do you get better fuel efficiency. And your engine must be tuned to take advantage of the extra octane or your just pissing money away. I believe the Tacoma's only require 87 octane.

The engine in the Toyota 05 and up Tacoma's and Corollas call for premium fuel and are vvti. Yes, octane gives more knock resistance. Engines with higher compression ratios are more likely to knock on lower octane fuels.

You didn't contradict anything I stated, so I am not sure why you quoted me. Though you elaborated on the knock resistance.

In some engines that have knock sensors they retard ignition timing to reduce knock. Retarding timing will reduce the engines efficiency. Some engines are rated to run regular but can improve efficiency by running premium though the cost benefit isn't there. Excessive knock will cause damage.

When I towed a heavy load in summer up hills I would use mid grade to reduce the possibility of knock, down hill or lighter loads it made no difference. 90 F150 351 4X4. @ 55 I got 19 mpg, with a heavy load 16 mpg.

BTW Good on Ford to push mpg up 20%.

And, even though its torque is rated lower than the 5.0 V8 (350 vs 380 foot-pounds), it makes it at 1500 RPMs, versus the V8 having to be revved up to nearly full grunt. That will be fantastic when towing. The SHO has proved it to be very thirsty for a V6, though, so I wouldn't plan on spending that gas money elsewhere, yet.

What amazes me is that the base V6 makes 300 bhp, and the 5.0 V8 with 2 more cylinders, and 1.3L more displacement only manages another 60 bhp on top of that.

Stick that turbo V6 in a Raptor-looking Ranger. Add low-range 4WD, and I may buy my first pickup ever...

It is my understanding that the 3.5 EcoBoost is torque limited in the Taurus/Flex because it is transverse mounted. Throw that thing in the RWD F-150 with a stout transmission and you'll see those torque figures jump.

PS my brother bought a infinity G35 coupe over a v8 mustang because he didn't like the idea that someone could spend $20,000(base mustang) and get the same looking car that he spent $30,000(GT mustang) for. :) I wonder if that is really whats going on here, could be the v6 has a de-tuned suspension compared to the GT. Not sure if this is true, I'm pretty sure the camaro v6 has a sports tuned suspension.

Yeah, it's a different calibration and the brembo package isn't available on the V6 either nor are the 19 inch wheels and Pirelli tires. Car and Driver had a V6 Mustang with the 19 inch wheels and Pirelli tires and they were surprised at the handling prowess of the car. RTR makes a set of 19" wheels that are supposed to be offered through Ford dealerships. Order a set and install some sticky tires to go with them.

I'm seriously impressed with the 2011 Mustang. So much so that I'm contemplating picking up a used one in a few years and modding it a little.
