Italian manufacturer VM Motori has designed and built several different diesel engines for many third-party applications. Since 2013 Fiat and its successors own VM Motori and sell projects to automotive manufacturers including GM, Jeep, and other companies. VM Motori offers different range of engines depending on the applications: automotive, industrial, marine, and power generation.

Automotive applications

3 Cylinder

R 315 SOHC I3, with a single overhead camshaft, four valves-per-cylinder, and common-rail direct fuel injection.

This engine was designed in 1998 with the related 4-cylinder variant R 420 SOHC. In 1999, VM granted Hyundai the license to manufacture both engines. Under terms of the agreement, Hyundai was able to manufacture the engines only to power its vehicles, while VM was free to grant other license agreements also in Korea, as happened in 2004 with GM Daewoo.

Further evolutions were named RA 315 (Euro 4 compliant, up to ) and A 315 (Euro 5 compliant, up to ).

Applications:

Hyundai Accent (power: ; torque: ) Hyundai Matrix (power: ; torque: ) Hyundai Getz (power: ; torque: )

HR 392 SOHC bore and stroke, straight-three engine, of an OHV pushrod design with two valves per cylinder. The block was cast iron, with an alloy head. It featured a four main bearing crankshaft, a balance shaft, and a Bosch VE3/10 fuel injection pump. A KKK 14 turbocharger was used, with an intercooler for the facelifted 'Nuova 33' of 1990. Although out of production, this was the biggest three-cylinder engine ever made for a car.
