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.”

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.
