👋 Introduction

Positioning:

The Lancia Delta Integrale, even from its 1986 inception (preceding the more famous Evoluzione models), was a homologation special designed for rallying. Its market position was that of a high-performance, compact all-wheel-drive sports hatchback, setting it apart from contemporary competitors.

Competitors:

While not a direct competitor, its performance ethos and AWD capabilities put it in a unique category. Competitors in spirit and performance might include rally-bred homologation specials from other manufacturers or high-performance European hatchbacks of the era.

Aerodynamics:

Distinctive box-flared wheel arches, front spoiler, and aggressive styling cues hinting at its motorsport pedigree.

Powertrain:

2.0L turbocharged 16-valve engine, permanent four-wheel-drive with a Torsen center differential (in later models, but the 1986 car had a viscous coupling).

Suspension:

Stiffened and performance-tuned suspension geometry optimized for grip and handling.
