The 2000 saloon kept the central part of the body (roof, doors, interior) and the entire drivetrain (except for some improvements to the fuel injection) of its predecessor, the second series of the Flavia.

The mechanics retained most of the Flavia's specifications including the front-wheel drive, boxer engine, independent suspension, and disc brakes all around, with vacuum assist and split-circuits (called "Super duplex" by Lancia).

The cosmetic changes to the 2000 Coupé were largely confined to a new grille (matte black instead of chrome) with headlamps incorporated into the now wider intake, new bumpers (with rubber strips on the HF), and the tail was shorn of its vestigial tailfins, with a raised and squared decklid.

[citation needed] The cars do not suffer the corrosion problems associated with later generation Lancia automobiles and are generally regarded as being more resistant than contemporaries from other Italian manufacturers.

[citation needed] The Bosch electronics that were developed specifically for the 2000s boxer engine raised its maximum power to 125 hp (92 kW), the same as contemporary BMW and Alfa Romeo cars.

This improvement, however, was never publicized by Lancia because the marketing department believed that their targeted customers would less favorably respond to a campaign that emphasized power and performance rather than quality, technical sophistication and riding comfort.
