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 doubt that. The 5.0 produces 412hp in the mustang but is detuned for towing and abuse in the F150. It is highly likely the Ecoboost 3.5 will undergo the same detuning. I would imagine it will land around 305-315hp putting it between the naturally aspirated 3.7 V6 and the 5.0 V8.

But unlike the other motors, the Ecoboost doesn't need to rev to make it's power so more than likely it will be around the same power level but with more torque. I also doubt it will be more than 400hp too. That would take larger turbo's with more revs and that's not desired in a truck.

Don't rate me down without doing your research. Even Ford said that power will be close to the 365hp in the SHO or so Car and Driver claims. Add to the fact that Ford is positioning the Ecoboost motor as a premium engine above the 5.0L in the F150 means it won't be lower in performance (or numbers) than the 5.0L.

I'm thinking it's going to out grunt the 5.0-liter V8, hence the higher tow rating. The EcoBoost is making 350 lb-ft in the Taurus/Flex because of limitations due to its transverse positioning/transmission.

I'm sure that given a "proper" longitudinal orientation in the F-150 with a heavy duty tranny, this thing will be pumping out close to 400 lb-ft.

Any word on the tranny's durability? And does this thing have a tow mode? You will spend a great deal of time at low RPM's which historically has been a killer of transmissions when towing.

My dad will be in need of a new boat hauler soon. I'm not sure how much longer a 1991 Chevy Astro with 300k miles will be tow capable.

It's probably the same 6 speed auto presently in their trucks. And yes it has a tow/haul mode.
