3.5-liter EcoBoost V6
V8 what? EcoBoost V6 is probably going to be a hot seller for the F-150

When we brought you news of Ford's overhauled F-150 powertrain lineup for 2011, most people were quite happy with the changes made. However, there were some that were skeptical about the possible power ratings for the optional EcoBoost V6 engine.

Some simply weren't buying into the idea that the 3.5-liter EcoBoost V6 -- a twin-turbocharged engine that sees duty in the Ford Taurus SHO and Ford Flex -- could possibly produce even more power in a truck platform that would undergo much more stress.

Today, however, Ford is giving the naysayers a healthy dish of crow to eat with the final power/torque figures for the EcoBoost V6 engine option in the 2011 Ford F-150. The engine will generate 365 hp at 5,000 rpm and an outrageous 420 lb-ft of torque at 2,500 rpm. Even more impressive is that 90 percent of peak torque will be available from 1,700 rpm to 5,000 rpm. Towing capacity with the new engine matches that of the larger 6.2-liter V8 engine option -- 11,300 pounds. Better still, all of this is achieved using regular unleaded fuel.

For comparison, the EcoBoost V6 generates 365 hp at 5,500 rpm and 350 lb-ft at 1,500 rpm in the Taurus SHO.

The new EcoBoost will be a more expensive engine option than the 5.0-liter V8 which generates 360 hp and 380 lb-ft of torque.

“Truck customers should think of the EcoBoost truck engine as a gas-powered engine with diesel-type capability and characteristics,” said Jim Mazuchowski, Ford's V6 engines program manager. “The twin turbochargers and direct injection give it the broad, flat torque curve that makes towing with a diesel so effortless – and hard acceleration so much fun.”

“Customers have embraced the EcoBoost solution of delivering the power they desire with the fuel economy they demand in a no-compromise package,” added Derrick Kuzak, group vice president, Global Product Development. “From the start, we have pledged that this solution applies to any engine and any customer. The EcoBoost truck engine for the 2011 F-150 will deliver those attributes and has been specially tuned and tested to deliver the best-in-class towing and capability our truck customers demand.”

The EcoBoost V6 engine option will be available for the F-150 in early 2011. Although Ford didn't give any specific fuel economy numbers for the engine, it will more than likely be more fuel efficient than the less powerful 5.0-liter V8.

Let me start by saying I have driven the new SHO Taurus and this new twin turbo 3.5L V6 is arguably a hot motor, for a mainstream Ford sedan. When it comes to trucks however, I'm not interested.

When it comes to a truck, I want a durable V8 engine. That isn't to say six cylinder engines can't be durable, look at the Ford 300 I6, arguably one of the best and most durable truck engines of all time. That motor however in contrast to the new 3.5 was under-tuned and underpowered - on purpose, to gain that legendary durability. The new 3.5 is under pressure (literally) and on the bleeding edge of what it's capable of right out of the factory. This engine has zero down time, as is proof by the torque curve. It's making boost as early as 1000 RPM and making peak torque at 1,500 RPM. As much as I like the engine, I don't see it lasting when being taxed day in and day out.

Admittedly, I didn't see anything wrong with the previous modular 5.4L V8 and 6.8L V10 engines. They made adequate power but more importantly they were up to the abuse challenge and have an excellent track record when it comes to reliability and longevity.

If I were buying a new F150 today my engine of choice would indeed by the 5.0. Having owned many generations of the Ford modular V8 in many, many flavors dating back to it's introduction in 1992 I have come to grow confident in it's performance, reliability and durability. The 5.0 is just the latest flavor of this excellent engine platform and is sure to serve well like it's predecessors.

That's the thing. Just like a overclocked vs. stock & watercooling vs. air-cooling in computers, the more complex/pushed designs give higher performance at the expense of reliability. Many F-150 owners have easily reached 200K ranges without engine rebuilds and while the 3.5 block is likely durable, I have yet to see long-term reliability tests on these complex engines. Your reliability needs are different for a Taurus SHO vs. a truck that you need every day for your job/hauling duties.
