In an attempt to capture attention from speed freaks and Earth lovers alike, Ford today released information about the new Ford EcoBoost engine. The 3.5-liter twin-turbo V6 pumps out 355 hp with 350 ft-lb of torque.

The EcoBoost will debut in the Ford Flex, Lincoln MKS, and Lincoln MKT later this year. Ford claims the engine competes in power with rivals, like the 4.6-liter V8 engines found on the Cadillac DTS, Hyundai Genesis, and Kia Borrego In fact, they are quite right. The engine on the DTS gets up to 292 hp and 288 ft-lb of torque, while the similar Hyundai/Kia machine gets up to 336 hp and 323 ft-lbs.

Ford's new EcoBoost V6 even beats out their own 4.6-liter V8, found on the Ford Explorer. That engine gets 292 hp and 300 ft-lb of torque.

Meanwhile, Ford estimates a 10 to 15% gain in fuel economy when compared to similar class vehicles. The American automaker will heavily push these figures on potential consumers, as the company sees more power and efficiency as a key to selling the three vehicles. "The beauty of EcoBoost is that it enables us to downsize for fuel efficiency, yet boost for power," said Ford product development VP Derrick Kuzak in a statement.

"We're able to decrease the size of the available engine - such as installing a V-6 versus a
V-8 - yet boost the power using turbocharging to deliver similar power and torque of that larger engine."

The Honeywell GT15 turbochargers operate in parallel at speeds of 170,000 rpm. They produce up to 12 psi, and should live for at least 10 years, or 150,000 miles.

Keith Plagens, a turbo engineer for the company, said, "We've tested the turbochargers at a much-higher duty cycle than a customer would ever experience. ... Our whole goal from the beginning was to make the operation of the turbochargers seamless, so the customer wouldn't even know they were there."

Direct fuel injection is all the rage these days, and Ford has included the system on their new engine. DFI helps make the engine more fuel efficient, and emit less C02, even at a cold-start.

The 2010 Ford Flex will be the first vehicle to offer the new Ford EcoBoost engine.

FORD'S NEW ECOBOOST TECHNOLOGY AT A GLANCE

The first in a wave of new Ford EcoBoostTM engines makes its debut in the Lincoln MKS, MKT and Ford Flex later this year as part of Ford Motor Company's global initiative to provide powertrains that deliver the fuel efficiency and power customers demand.

The twin-turbocharged 3.5-liter V-6 EcoBoost engine delivers the performance found in a normally aspirated V-8 while maintaining the fuel economy found in a normally aspirated V-6 engine.

A look at the highlights of the EcoBoost story:

* Power and fuel economy: The twin-turbocharged 3.5-liter Duratec V-6 EcoBoost engine produces 355 horsepower at 5,700 rpm and 350 ft.-lb. of torque at 3,500 rpm. A 10-15 percent fuel-economy benefit is expected versus normally aspirated 4.6-liter V-8 engines in the same competitive class.

"The beauty of EcoBoost is that it enables us to downsize for fuel efficiency, yet boost for power," said Derrick Kuzak, Ford's group vice president of Global Product Development. "We're able to decrease the size of the available engine - such as installing a V-6 versus a
V-8 - yet boost the power using turbocharging to deliver similar power and torque of that larger engine."

* Engine: Base engine architecture comes from the proven Duratec 3.5-liter V-6. To handle the increased torque that EcoBoost delivers, some upgrades were made to some of the components, such as the cylinder block, crankshaft, connecting rods pistons and exhaust valves to ensure the EcoBoost V-6 engine is as robust as possible.

"The Duratec 3.5 family is a good example of Ford's forward planning in terms of powertrain technologies," said Brett Hinds, EcoBoost design manager. "The engine architecture itself was well protected for high-boost applications, so it didn't require an extensive durability program. It was in good shape to start with."

* Turbochargers: Two Honeywell GT15 turbochargers with water-cooled bearings and operate in parallel, spinning at approximately 170,000 rpm up to 12 PSI. They are rated for a 150,000-mile, 10-year life.

"We've tested the turbochargers at a much-higher duty cycle than a customer would ever experience," said Keith Plagens, turbo systems engineer. "Our whole goal from the beginning was to make the operation of the turbochargers seamless, so the customer wouldn't even know they were there."

* Direct fuel injection: A cam-driven high-pressure fuel pump feeds the fuel injectors at pressures ranging from 200 to 2,175 PSI (pounds per square inch) depending on customer driving. A typical port fuel injection system operates at pressures of around 60 PSI. Six sprayers in each injector target fuel into the cylinder, resulting in a cleaner and more-efficient fuel burn and better cold-start emissions.

"By injecting the fuel directly into the combustion chamber and under high pressure, the fuel is sent exactly where we want it to be for a given combustion cycle," said Joseph Basmaji, direct injection fuel system technical specialist. "This aids burning of fuel more efficiently and effectively."

Talk about NA engines all The new M's 3.2L 333hp 4.0L 414hp 5.0 507hp from bmw and all were NA. always 100hp per liter.

170,000 rpm 12psi turbo that can last 150,000 kms? that is what sets this engine apart from the others, if they put 30psi into this engine would it be any better engineered? hell no, in my opinion it would be worse.

This is a great engine. Other company V6s might make as much power with less displacement but this will make more torque which is important to the jobs the cars with the engine will carry out.

Finally, Ford got their feet on the ground. That's way better than the humongous and shabby 4.0 L V6 that the mustang has. Only 210hp......

Well, it's American, but not quite leadership. Audi's 3.0 liter TFSI twin-turbo V6 has 330 horsepower. Quite close to the 355 bhp of this 3.5 liter out of only 3.0 liters...

i don't understand how it's possible to get 292 bhp from a 4.6 litre V8... that's absolutely shocking. Mercedes gets 292 bhp from a 3.5 litre V6! even this engine isn't really all that amazing... Audi's 3.0 litre supercharged engine gets similar figures. i *suppose* it's a step in the right direction tho...
