What the car is and where it came from
The Lancia Delta HF is a Group A rally car introduced for the 1987 World Rally Championship season. It replaced the Delta S4 and was built by Lancia for Martini Lancia.
How it works, in terms someone would actually use
It is a Group A rally car built for Martini Lancia to compete in the World Rally Championship. It has a front-mounted two-litre turbocharged engine and four-wheel-drive.
What it gets right
It gets right the balance of Group A compliance, four-wheel-drive traction, and turbocharged responsiveness needed for gravel, snow and tarmac stages.
What it does not
It does not appear in the material as a road car design exercise. The source says only that the rally car was based on the Lancia Delta road car — no details of that road car are given.
What it changed
It changed rally car dominance: it replaced the Delta S4 and became the most successful car in WRC history.
Who it is for, and who it is not
It is for rally engineers, drivers and fans who value proven, evolution-led competition hardware. It is not for collectors seeking original road-car context — none is provided.
Is it worth your time
Yes. It won 46 World Championship rallies and six consecutive manufacturers’ titles — a record — between 1987 and 1992.
