Ford EcoBoost V6 Engine  (Source: Ford)
EcoBoost is proving very popular with truck buyers

With automakers focused on increased fuel efficiency these days, the move to smaller displacement engines with turbochargers is happening at a rapid pace. Ford was one of the first to head in that direction on the domestic market with its EcoBoost V6 engine that has so far been used in the Taurus, F-150, Flex and several other Lincoln vehicles.
 
The F-150 with the EcoBoost twin turbo V6 engine has proven to be very popular. In fact, the combination of the F-150 and the EcoBoost is so popular that Ford is raising the sales forecast for the truck. Ford says the reason for the forecast upgrade is that the market demand for the EcoBoost F-150 has been greater than expected. 
 
Previously Ford had expected about 40% of the F-150 trucks sold to use the EcoBoost 3.5L engine. Ford is now predicting that about 45% of the F-150 trucks it sells to have the EcoBoost with a total retail sales number of about 100,000 in 2011. Ford full-size pickup sales -- including HD vehicles and fleet vehicles – are up almost 8% to 416,488 units through September 30.
 
Traditionally, the V8 is the engine of choice in the F-150 and truck market overall. Ford does provide a version of the 5.0-liter V8 used in the Mustang GT for F-150 buyers that still want eight cylinders on tap.
 
During the last few months, the WSJ reports that the EcoBoost has accounted for 42% of F-150 sales. This is in part thanks to the robust power and towing capacity mixed with fuel economy averaging 18 mpg compared to the 14-17 mpg for V8-equipped trucks.

Repeat after me: When towing a heavy load, HP is a secondary consideration. It's all about TQ across the entire RPM band, especially down low.

Go check out Detroit Diesels. Note how their 16 to 20L engines make "only" 400 or 500 HP, but generate 1500 or more foot-pounds of torque as low as 1000 RPM.

A V6 just isn't going to make the same torque as a big-block V8. It's as simple as that.

Unless that is a big bored V6 and it has some help from a supercharger.

Repeat after me: What follows after the V isn't as important as the rest of the engine specs.

This is no replacement for displacement.

Let me know when there's a change. And no, turbo's aren't it.

I'll second that.

Get with the times, people.

A modern forced induction engine will usually make a better spread of torque than a naturally aspirated engine. It will be more fuel efficient and weigh less than a N/A engine that makes similar performance. If engineered well and maintained correctly, they can be just as reliable. Naturally, maintenance costs may be higher due to greater complexity of the engine, but you can't have everything.

Take a look at those silly Germans, BMW. They used to be big flag wavers for the N/A crowd. Now, they are making loads of turbo engines, because of the reasons above.

Also, what was the last time you saw a big diesel that WASN'T turbocharged? Certainly here in Australia I can't remember the last time I saw a prime mover that didn't have a turbo.

BIG (being the operative word) diesel + turbo = WIN

Small engine + turbo = not enough torque to effectively move a heavy load (which is what trucks are engineered to do)

If you're buying a truck, it should be for hauling/towing. Putting a small-ish V6 in a TRUCK made to haul/tow WILL result in a lower total payload capacity. Last time I checked the F-150 was a truck. Ergo, if you're buying an F-150 with plans to haul/tow a big load, and you choose the V6, you've made a grave mistake.

Nobody's attacking the idea of more fuel-efficient people movers. But trucks need BIG engines with lots of cubes to make the torque needed to haul loads.

Again, there is no replacement for displacement.

And you've hit on one of the main reasons turbos are unusually not chosen for most designs - costs. Especially maintenance costs should one fail or start to go bad (which is not uncommon).

Did I just go back 30 years? Turbo's are in an increasing number of vehicles. And this won't be stopping anytime soon. These arguments are silly and have yet to produce any real proof. Just a rehashing of the same old anecdotal BS.

Actually, there is a reason why we didn't see turbos in pickup trucks or didn't that dawn on anyone? Only now are they offering the turbocharged V6 for ONLY. ONE. REASON. Fuel economy. In every other important parameter it is inferior.

Wrong. The V6EB makes MORE torque than the 5.0 V8 through a wider rev range. Also, I think you'll find the V6EB has as good as, if not higher, payload and towing capacity as the 5.0 V8.

What makes you think that turbo's work in large applications, but cannot be scaled down?

Also I said 'Prime Mover' not people mover. That might be an Australian term though - you guys might call them 'Big Rigs' or '18 Wheelers'? How many of these use non-turbocharged engines?

On the contrary, forced induction engines often make better torque than larger, naturally aspirated engines. And the torque comes on strong early, quite often hitting peak torque and staying there for a good chunk of the rev range. So no, it's not as simple as that.

Of course, the reality is far more complex and depends on a huge amount of factors. Too many to discuss here. Suffice to say, take a look at the torque figures and the revs they come in at for the Ecoboost 3.5 V6 and the Coyote 5.0 V8. Speaks for itself.

Often? There are rare exceptions to this rule, so please do enlighten us with the paradigm change of small displacement creating more torque than large displacement. Especially in large diesel...
Either way, for most city-dwellers, that 3.5 is all that's needed, and praise to Ford for their ingenuity.

??? "Rare exceptions" makes what the poster said correct, would it not? We sure have a LOT of people that don't understand what a turbocharger is or does. With a turbo you can easily place your powerband where you want it making small displacement engines drive like larger one's. And with the added benefit of small displacement when you're not on it. That's the whole point of turbocharging.

On the surface that sounds fine, but when considering a vehicle that will potentially be subject to extended high load conditions, it is inevitable that the smaller displacement turbo engine (with all else being equal...) will wear out sooner.

There is no free lunch. They can use good engineering and make it last as long as the older design, but by the same token they can use the engineering to improve the NA engine to make it even more long lasting.

There's a label for people buying this turbo V6 truck. Beta-tester. No matter how much testing an auto manufacturer puts into a design, later through real world applications they find flaws they missed and revise the design.
