F-150 to get new engines including EcoBoost V6

Nice. The EcoBoost doesn't even need premium gas

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.”

Pretty impressive. GM Powertrain has the goods. Now they need to update the truck engine lineup in response to this.
The 5.0L cammer matches the ratings of the GM 6.0L engine. The 6.2L is close to the 6.2L GM mill.
GM needs to get the Camaro's 3.6L into the trucks (which should have received the 4.2L inline 6 a long time ago).

From autoblog:
Since they tune turbo engines these days to have such flat torque curves, if the ecoboost holds around 400 lbft to 6000 rpm that's a 450hp engine.
Following Ford's presentation, we were taken to an engine dynamometer lab where an F-150's EcoBoost V6 was set up. The engine was not taken up to full power in front of the media, but we did see it go up to 4,000 rpm where it was held for about 10 minutes with an output of 410 lb-ft and 310 hp. Under those conditions it will hold 16 psi of boost with the turbos spinning at 175,000 rpm and a turbo temperature of 1,700 degrees F.

Simply a function of spool and boost. For production vehicles they tend to try to keep lag and spool time minimal for greater responsiveness. That tends to mean smaller turbines and compressors but peak boost low in the rev range. However, depending on the turbo size, boost may taper off in the upper revs. In addition if they are running it on 87 it is less likely that they will maintain the torque up to redline.
