The Cosworth-Opel KF engine is a production-based, high-revving, prototype, four-stroke, 2.5-liter, naturally aspirated, V-6 racing engine, originally designed, developed and produced by Opel, in collaboration with Cosworth, for the DTM and later ITC, between 1993 and 1996.[5] The engines were tuned by Cosworth, and were based on the Isuzu 6VD1 (1996) 75° production engine, as used in the Opel Monterey, Opel Frontera Limited, Trooper, Rodeo, and Amigo.[6]
