Italian manufacturerVM Motori has designed and built several differentdiesel 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.
1.5 L (1,493 cc or 91.1 cu in)I3, with asingle 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 grantedHyundai 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 withGM Daewoo.[1][2]
Further evolutions were namedRA 315 (Euro 4 compliant, up to 105 PS (77 kW; 104 hp) ) andA 315 (Euro 5 compliant, up to 115 PS (85 kW; 113 hp) ).
