The Kappa was not particularly popular, with only 80,000 made in total. Italy remained Kappa's most important market, absorbing the bulk of sales. It is also worth noting that in Poland, where Fiat Auto is the biggest domestic car manufacturer, Kappas served as official government cars (replacing Themas). This boosted the Kappa's profile in that country and gave it a peculiar cachet, which is why the Kappa enjoys a solid enthusiast base there.
- 1994 - Kappa production begins.
- 1996 - An estate car joins the lineup. The naturally-aspirated 2.0-litre gasoline engine is fitted with a variable geometry inlet manifold. Inside the cabin, the seats are replaced by a new design, including new upholstery patterns.
- 1997 - The coupé is launched, while at the same time, some changes are made to the interior, trunk, suspension and engine bay, as well as new alloy wheels. Coupe production begins.
- 1998 - The 2.0L turbocharged four-cylinder engine gets replaced by the five-cylinder, while the turbodiesel was upgraded to a JTD engine. The bumper guards, previously black, are changed to body-coloured, and the base trim level, LE, is dropped, leaving only the more lavish LS and LX. At the same time, a special trim level is introduced for the turbocharged gasoline engine, called simply the "Turbo", distinguished by the lack of chrome decals around the window frames. The interior materials are also upgraded across the lineup, including the addition of a leather-wrapped steering wheel and front central armrest.
- 1999 - The other two five-cylinder engines are modified along with the air conditioning unit.
- 2000 - The Kappa gains xenon HID headlamps. Production ceased in mid-2000 (Coupé's earlier in the year).
The station wagon version of the Kappa, designated "SW" by Lancia, was designed and built by the famous Pininfarina and did not differ from the saloon exterior dimensions - the focus was clearly on presentation rather than cargo space.
