Lancia Delta dominated the WRC (World Rally Championship) with six consecutive Group A manufacturer titles. Between 1987 to 1996 Group A was based on commercially available production cars, so the base vehicle was vitally important as each manufacturer continually sought to incorporate elements necessary for rally car performance into the production models. Delta was at the forefront of this and during the seven years it was active in the WRC from 1987 to 1993, there were four types: HF 4WD; HF Integrale; HF Integrale 16V, HF Integrale Evoluzione (Deltona). While all Group A models featured the 2-liter turbo + full-time 4WD, the HF 4WD is the only one in the series that features a narrow body without wide fenders. As 1987 was its first year of competition, the Lancia was unable to take full advantage of the regulations, however, it had superior overall specifications compared to its rivals and dominated the series in that year with eight wins from eleven races. The HF 4WD No. 4 that won the 10th round of the 1000 Lakes Rally was driven by Markku Alen/Ilka Kivimaki, who had been competing with Fiat/Lancia for many years and was known as the uncrowned rally king. In that year he recorded three wins, including the 1000 Lakes and Portugal/Acropolis.
