The development programme aimed at transforming the boxy-shaped, Giugiaro-designed Delta hatchback into a competitive rally car had been necessitated by the banning of the Group B supercars at the end of 1986. Having experimented with a system combining both a conventional (Volumex) supercharger and a turbo on their Delta S4 Group B rally car, Lancia eventually opted for turbo-charging alone for the less exotic Group A Delta HF. Already a fine handling car courtesy of its tuned suspension, the Delta HF moved up a class with the introduction of a state-of-the-art four-wheel-drive transmission incorporating Ferguson viscous couplings and a Torsen differential.
Badged as the ‘Delta HF 4WD’ on its introduction in 1986, the model retained the Volumex blower initially before switching to a straightforward turbo when transformed into the legendary Integrale in 1987. The latter would prove a supremely capable rally car yet in road trim remained a thoroughly practical family hatchback. Integrale performance was boosted further by the introduction of a 16-valve cylinder head for the 2.0-litre four-cylinder engine in 1989, maximum power increasing to 200bhp and top speed to 220km/h (137mph).
Homologated to maintain the works rally team’s competitive edge, the first Evoluzione models were manufactured towards the end of 1991, incorporating wider front and rear track, appropriately altered bodywork and an engine re-mapped to produce 210bhp among many other detail improvements. Although the model was sold officially in the UK, the Integrale was only ever available with left-hand drive.
One of the final Evoluzione models completed before the introduction of the catalyst equipped Evoluzione II, the example offered here in very good general condition, finished in black with Alcantra interior. Recently serviced the car is sold with its French Carte Grise.
