EcoBlue is the marketing name for a range of diesel engines from Ford of Europe. The EcoBlue engines were developed under the codename "Panther" by Ford engineering teams in the U.K. and Germany, and are expected to succeed the Duratorq diesel engines, offering optimised fuel efficiency and reduced CO₂ and NO_x emissions.

An initial 2.0-litre (1,995 cc) variant will be offered with 105, 130 and 170 PS (77, 96 and 125 kW; 104, 128 and 168 hp) in commercial vehicle applications. This engine architecture is capable of delivering more than 200 PS (147 kW; 197 hp), and will later feature with such power outputs in Ford passenger cars, alongside a 1.5-litre (1,498 cc) variant.

In early 2018 Ford launched its Ranger Raptor with a biturbo 2.0-litre (1,995 cc) EcoBlue producing 213 PS (157 kW; 210 hp) and 500 N⋅m (369 lb⋅ft) of torque.^[1] Also in 2018 Ford launched an even higher spec biturbo 2.0-litre (1,995 cc) EcoBlue producing 238 PS (175 kW; 235 hp) for the Edge Titanium, ST-Line and Vignale SUV in Europe. ^[2] A North American-spec version of the biturbo 2.0-litre (1,995 cc) EcoBlue was planned debut in the 2020 Transit, but production of the engine was canceled before launch due to the COVID-19 pandemic as well as a lack of market demand to justify federalising the engine.^[3]

An all-new engine architecture is claimed to deliver reduced friction and a clean-burning combustion system. The engines will meet Euro 6 emissions standards. Ford says that a 13 percent improvement in fuel efficiency is obtained through friction reduction enhancements.

A new strong lightweight engine block features an aluminium ladder below that reduces noise and vibration. The crankshaft from the piston is offset by 10mm to allow piston side load against the cylinder wall to be reduced hence decreasing friction and wear with the diameter also reduced to improve efficiency.

New belt-in-oil system are being used to drive the cams to reduce friction while the head’s intake system is engineered to equally balance the air between each cylinder.

Centralized eight-hole-nozzle piezo injectors are being used to inject diesel at 2,000 bar, much higher than previous engines.^[4]
