Cosworth KF engine

The Cosworth-Opel KF is a four-stroke, 2.5-litre, naturally aspirated V6 racing engine that Opel designed, developed and produced in collaboration with Cosworth for the DTM and later the ITC touring car series between 1993 and 1996. Cosworth tuned the engines, which were based on the 75 degree Isuzu 6VD1 production V6 used in the Opel Monterey, the Opel Frontera Limited, the Trooper, the Rodeo and the Amigo. It powered the Opel Calibra DTM V6 4x4, and since 2000 it has also been used in the Gould GR51 open-wheel car of the Hillclimb and Sprint Association British Sprint Championship, which makes it one of the few touring car engines of its era to stay in competition in another kind of racing.
