List of VM Motori engines

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.

R 315 SOHC
1.5 L (1493 cc) 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 105 PS ) and A 315 (Euro 5 compliant, up to 115 PS ).
