The Hyundai U engine is a series of three or four-cylinder diesel engines made for automotive applications by the Hyundai Kia Automotive Group. The U series of engines includes the smallest automotive diesel engines produced by Hyundai.{{cite web | url= http://auto-report.net/?p=2828 | title= Hyundai Introduces New R-Diesel Engine | date= 5 November 2008 | work= Auto Report | id= | accessdate= 2012-07-09 | quote= The R-Engine brings Hyundai's diesel engine family fully up-to-date as it joins the U-Engine (1.1-liter, 1.4-liter and 1.6-liter), the A-Engine (2.5-liter) and S-Engine (3.0-liter V6). | archive-date= 2011-12-20 | archive-url= https://web.archive.org/web/20111220033458/http://auto-report.net/?p=2828 | url-status= dead }}

{{anchor|D3FA}} 1.1 L (D3FA)

The {{convert|1120|cc|L|1|order=flip|abbr=on}} U diesel engine is a 3-cylinder version of the 1.5L U series unit and is made with cast iron block and aluminum cylinder head with chain driven DOHC with 4 valves per cylinder, Delphi common rail direct injection (CRDi), variable geometry turbocharger (VGT) and intake air swirl control. Bore and Stroke are {{convert|75x84.5|mm|2|abbr=on}}. It creates {{convert|71|-|75|PS|kW hp|0|abbr=on}} at 4,000 rpm and {{convert|15.6|-|18.3|kgm|0|abbr=on}} of torque between 1,750 and 2,500 rpm.

It is one of Hyundai's most efficient engines with a fuel consumption of {{convert|4.2|L/100 km|abbr=on}}, and emits 112 g/km of CO2. The engine also incorporates a 1½ engine order balance shaft mounted under the crankshaft driven by helical gears to manage engine vibration.

;Applications

{{anchor|D3FB}} 1.2 L (D3FB)

The {{convert|1186|cc|L|1|order=flip|abbr=on}} U diesel engine utilizes three cylinders and is made with cast iron block and aluminum cylinder head with chain driven DOHC with 4 valves per cylinder. It produces {{convert|75|PS|kW hp|0|abbr=on}} at 4,000 rpm and {{convert|19.4|kgm|0|abbr=on}} of torque between 1,750 and 2,250 rpm.

;Applications

{{anchor|D4FC}} 1.4 L (D4FC)

The {{convert|1396|cc|L|1|order=flip|abbr=on}} U diesel engine utilizes four cylinders and is made with cast iron block and aluminum cylinder head with chain driven DOHC with 4 valves per cylinder, Bosch common rail direct injection (CRDi), fixed geometry turbocharger (FGT) and intake air swirl control. It is a reduced stroke version of the 1.5L U series with Bore and Stroke at {{convert|75x79|mm|2|abbr=on}}.

It produces {{convert|90|PS|kW hp|0|abbr=on}} at 4,000 rpm and {{convert|22.4|-|24.5|kgm|0|abbr=on}} of torque between 1,500 and 2,500 rpm.

;Applications

{{anchor|D4FA}} 1.5 L (D4FA)

The {{convert|1493|cc|L|1|order=flip|abbr=on}} U diesel engine has four cylinders and is made with a cast iron block, aluminum cylinder head with chain driven DOHC (4 valves per cylinder), Bosch common rail direct injection (CRDi), variable geometry turbocharger (VGT) and intake air swirl control. Bore and stroke are {{convert|75x84.5|mm|2|abbr=on}}. It produces {{convert|89|hp|kW PS|0|abbr=on}} and {{convert|159|lbft|Nm|0|abbr=on}} torque in the Hyundai Getz and {{convert|108|hp|kW PS|0|abbr=on}} at 4,000 rpm and {{convert|174|lbft|Nm|0|abbr=on}} of torque at 2,000 rpm in the Kia Rio and higher spec Hyundai Getz models. Introduced in 2005 this engine replaced the 1.5L 3-cylinder D-engine common rail Diesel sold in the Hyundai Getz and Accent models which was notably less refined.
