Overview
The Lancia Delta HF Integrale in privateer and satellite-team hands deserves a different history from the design evolution of the factory Group A car. HF Grifone, Jolly Club and Astra Motorsport were separate organisations, serving different drivers, sponsors and competitions. Grifone was already running championship-winning and competitive Deltas before the factory withdrew.
The 1992 Martini-backed Jolly Club operation was a factory-developed successor programme in the WRC, whereas smaller teams and privateers fielded Deltas in national/European rallies and occasional WRC appearances well into the mid-1990s. They could use different mechanical specifications even under the same FIA Group A homologation.
