EcoBoost is a family of turbocharged, direct injected six-cylinder and four-cylinder gasoline engines produced by the Ford Motor Company. Engines equipped with EcoBoost technology are designed to deliver power and torque consistent with larger displacement, naturally aspirated engines while achieving approximately 20% better fuel efficiency and 15% reduced greenhouse emissions than these same engines. Relative to the power output and fuel efficiency of hybrid and diesel technologies, Ford sees EcoBoost as an affordable and versatile alternative and intends on using it extensively in future vehicle applications.[1]

EcoBoost gasoline direct-injection turbocharged engine technology adds 125 patents and patent applications to Ford's 4,618 active and thousands of pending U.S. patents.[2]
The V6 EcoBoost engines are being assembled at Cleveland Engine Plant No. 1 in Brook Park, Ohio.[3] The 2.0 L I4 EcoBoost engines will be produced at the Ford Valencia Engine Plant in Spain in 2009.[4] The 1.6 L I4 EcoBoost engines will be made at the Ford Bridgend Engine Plant in the United Kingdom.[4] The future small displacement I3 EcoBoost engine will be produced both at the Ford Cologne Engine Plant in Germany and at Automobile Craiova in Romania.[4]
By 2012, the company plans to produce 750,000 EcoBoost units annually in the US and 1.3 million globally in the world market. Ford expected over 90-percent of its global vehicle lineup (includes North American lineup) to offer EcoBoost engine technology by 2013.[4][5]
Volvo used the term GTDi (Gasoline Turbocharged Direct injection) for the 1.6L I4 engine when introducing Volvo S60 Concept[6] and for the 2.0L I4 engine when introducing Volvo XC60.[7]
Ford has announced a 1.0-litre, three-cylinder turbocharged engine for the EcoBoost family developed at Ford's Dunton Technical Centre in the UK. Production is to start in April 2012. The 1.0 comes initially in two versions; a 74 kW (100 PS, 98 hp) and a 92 kW (120 PS, 118 hp). The 120 PS version will deliver a maximum of 170 Nm (125 lb-ft) from 1,300-4,500 rpm and 200 Nm (147 lb-ft) on overboost, which makes for a broad torque curve when compared to on-road diesel engines. The engine block is cast iron instead of aluminium for up to 50% faster warm-up.[8][9] Due to natural vibrations of the 3-cylinder design, the flywheel is unbalanced (unlike the traditional method with counterbalance shafts). The engines will be produced in Köln, Germany, with production to later expand in Craiova, Romania. Production is expected to be 700,000-1,500,000 units per year. The engine will be available in Ford Focus and the Ford Focus-based B-MAX, C-MAX and Grand C-MAX
Ford has so far unveiled three different four-cylinder engines equipped with EcoBoost technology in concept and production vehicles. Like the 3.5 L EcoBoost V6, all the engines are turbocharged and direct injected. The production engine family was officially announced at the 2009 Frankfurt Motor Show.[10]
A 1.6 L version was first unveiled in the 2009 Lincoln C Concept. The engine is rated at 180 bhp (130 kW) and 180 lb·ft (244 N·m).[11]
Another 1.6L version of 150 bhp (110 kW) is to go on selling in the European market, having lower consumption and CO2.[12] 1.6L Ecoboost has 160 bhp (120 kW) version used in Ford Mondeo.

This engine first appeared in the 2007 Lincoln MKR Concept under the name TwinForce.[22] The engine was designed to deliver power and torque output equivalent to a typical 6.0 L or larger displacement V8 while achieving at least 15% better fuel efficiency and reduced greenhouse emissions compared to the V8 engine. In the MKR the concept TwinForce engine was rated 415 hp (309 kW) and 400 lb·ft (542 N·m) of torque, as well as run on E85 fuel.[23] When the same prototype engine reappeared in the Lincoln MKT concept in 2008 North American International Auto Show, the name was changed to EcoBoost. Official EcoBoost production began on May 19, 2009 at Ford's Cleveland Engine Plant No. 1.
The production engines use the Duratec 35 V6 engine block. The fuel charging and delivery systems can attain high fuel pressures of up to 2150 PSI, necessary for efficient operation of the direct fuel injection system. It uses two Garrett GT15 turbochargers which can spin at up to 170,000 rpm and provide 12 PSI of boost. The turbos are set up in a twin-turbo configuration. The engine can consume up to 25% more air over the naturally aspirated counterpart. Through the use of direct injection, the engine needs only regular-grade gasoline to run, though premium fuel is recommended. The EcoBoost V6 was first available as an engine option for 2010 Lincoln MKS, followed by 2010 Ford Flex, 2010 Ford Taurus SHO, and 2010 Lincoln MKT.[24] The fuel charging and delivery systems were co-developed with Robert Bosch GmbH.[25]
In 2009 Ford modified a experimental 3.5 V6 EcoBoost engine with E85 direct injection and gasoline port fuel injection, which achieved a BMEP score of 305 psi (27 bar), which translates to approximately 553 pound-feet (750 N·m) of torque and 316 horsepower (236 kW)@3000 rpm (flat torque curve from 1500-3000 rpm).[26]
