The 1.0-liter EcoBoost – available for Ford Fiesta and the 2015 Focus was chosen by a panel of 82 automotive journalists from 35 countries at Engine Expo 2014 in Stuttgart, Germany. The award is based on factors like driveability, performance, economy, refinement and technology.
“To deliver the complete package of eye-popping fuel economy, surprising performance and real refinement, we knew this little 1.0-liter engine would have to be a game changer,” said Bob Fascetti, vice president, Ford Powertrain Engineering.
According to Ford, vehicles equipped with the 1.0-liter EcoBoost engine are now available in 72 countries worldwide. Later this year, Ford says U.S. customers will be able to buy the new Focus 1.0-liter EcoBoost. The Fiesta 1.0-liter EcoBoost is in dealerships now.
The engine’s compact, low-inertia turbocharger spins up to dizzying 248,000 rpm – more than 4,000 times per second and almost twice the maximum rpm of the turbochargers powering 2014 Formula 1 race car engines. No turbo lag issues here.
The tiny three-cylinder 1.0-liter engine features a cylinder head with an integrated and cooled exhaust manifold that lowers exhaust temperatures, which optimizes fuel economy and emissions.
Engineers know a three-cylinder engine design is inherently unstable and prone to shaking and vibration, particularly at low RPM. Ford mitigates this using an improved flywheel and front pulley design.
Internal engine friction is reduced by specially coated pistons, low-tension piston rings, low-friction crank seals and a cam-belt-in-oil design. A variable-displacement oil pump tailors lubrication to demand and optimizes oil pressure for improved fuel efficiency.
According to automotive buff books, the 1.0L engine will be available in a 123-hp version coupled to a six-speed manual gearbox, and a 99-hp version to be offered later.
