Ford plans to introduce 3-cylinder engine

Automaker will use EcoBoost technology


DEARBORN, Mich. -- Ford Motor Co. plans to introduce its smallest engine ever by 2013, part of the race to improve fuel economy across the industry.

Ford said Thursday it's working on a one-liter, three-cylinder engine that will be available in small cars globally. Ford didn't say which cars will get the engine, but it plans to release more details this fall.

Currently Ford's smallest engine available in the United States is the 1.6-liter, four-cylinder used in the Ford Fiesta subcompact. That engine has 120 horsepower and gets up to 38 miles per gallon of gasoline on the highway.

Ford said the new three-cylinder engine would match that power but be more efficient. The engine has Ford's EcoBoost technology, which uses turbocharging, direct injection, and variable camshaft timing to boost performance.

"No one's ever built a three-cylinder engine quite like this," said Joe Bakaj, Ford's vice president of global powertrain engineering.

Three-cylinder engines are common in Europe and Asia, but the only one currently available in the United States is in the Smart Fortwo. The Fortwo has a 70-horsepower engine and gets 41 miles per gallon on the highway.

EcoBoost technology is currently available on four Ford products -- the F-150, the Ford Flex and Lincoln MKT crossovers, and the Taurus SHO sedan. Ford is adding it to the lineup for the Edge crossover and the Explorer this summer. The starting price of the Flex SEL with EcoBoost is $40,080, or nearly $8,000 more than a Flex SEL with the base engine. It costs $4,400 to add EcoBoost to an F-150 XL.

Still, the option has been popular with some customers. Forty-one percent of individual F-150 buyers chose the EcoBoost option in May, the company said.
