The Hyundai U engine is a Diesel. And comes in three-cylinder and four-cylinder versions for automobiles, and is currently the smallest one produced by Hyundai Kia Automotive Group.

1.1L

The 1.1L 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, Bosch common rail direct injection (CRDi), variable geometry turbocharger (VGT) and intake air swirl control. Bore and Stroke are 75 mm x 84.5 mm. It creates an impressive 74 hp (55 kW; 75 PS) at 4,000 rpm and 112 lb⋅ft (152 N⋅m) of torque at 2,000 rpm. It is one of Hyundai's most efficient engines using only 4.2L/100 km (56 MPG), and emits a minuscule 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. It is currently fitted to the Kia Picanto and Hyundai i10 models.

1.4L

The 1.4L 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), variable geometry turbocharger (VGT) and intake air swirl control. It is a reduced stroke version of the 1.5L U series with Bore and Stroke at 75 mm x 79 mm. It produces 74 hp (55 kW; 75 PS) and 162 lb⋅ft (220 N⋅m) of torque in base Hyundai i20 models and 89 hp (66 kW; 90 PS) and 162 lb⋅ft (220 N⋅m) of torque in higher spec Hyundai i20 models.

1.5L

The 1.5L 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), variable geometry turbocharger (VGT) and intake air swirl control. Bore and Stroke are 75 mm x 84.5 mm. It produces 89 hp (66 kW; 90 PS) and 159 lb⋅ft (216 N⋅m) torque in the Hyundai Getz and 108 hp (81 kW; 109 PS) at 4,000 rpm and 174 lb⋅ft (236 N⋅m) of torque at 2,000 rpm in the Kia Rio and higher spec Hyundai Getz models. Introduced in 2005 this engine replaced the VM Motori sourced 1.5L 3-cylinder common rail Diesel sold in the Hyundai Getz and Accent models and which was notably more unrefined.

1.6 L

The 1.6-litre U Diesel engine (known as D4FB) from the Žilina (Slovakia) Kia factory is a bored-out version of the 1.5-litre U series engine (77.2 mm versus 75 mm) and is used in the KIA Cerato 1.6CRDi, KIA Cee'd 1.6CRDi, Kia Soul and Hyundai i30 models. It develops 89 hp (66 kW; 90 PS) or 113 hp (84 kW; 115 PS) and 173 lb⋅ft (235 N⋅m) or 188 lb⋅ft (255 N⋅m) of torque, dependent on the vehicle application and was the "best in class" diesel engine in the world till now and present time. In 2009 it refined to the 1.6 U2 version and to 126 hp (94 kW; 128 PS) with 195 lb⋅ft (264 N⋅m) of torque..
