The range for Tempra was almost the same of Tipo's and Dedra's, except for sport's engines, but, contrary to Lancia's cousin, Tempra also had two versions with carburettor engines; the 1372 cc and 1581 cc, one with 76 PS and the second with 86 PS. Both of them faded out in 1993 cause of the new European emission standards, and so all models got the catalytic converter and electronic injection. Anyway, 1372 and 1581 also had electronic injection version, together with carburettor ones, but they had different power; 1372 and 1581 carburettor engine had 55 kW and 64 kW, electronic injection had 51 kW and 55 kW. Transmission was a standard 5 speed manual transmission, but for the first time for a mid size sedan was offered as alternative the Tempra Selecta which adopted the continuously variable transmission already tested on Fiat Uno, Panda, Ritmo and Tipo. Never before, a mid size Fiat car adopted the CVT. For 2.0 model, was adopted a standard 4-speed automatic transmission.
During the 6 years production time, Tempra never had substantial changes. Only 1581 engine (the most sold) had a review between 1993 and 1994, with a new Multi-point Fuel injection system in place of the former Singlepoint, which raised the power from 55 kW to 66 kW.
Chassis and main parts (most notable, the doors) were in common with Fiat Tipo. Other vehicles, derived from the same project were Lancia Dedra (Tempra's most similar cousin, sharing all the mechanical components), Lancia Delta second generation, Alfa Romeo 155, Alfa 145 and Alfa 146, which had been all produced in the same period of Tempra.
Quattroruote, the most important Italian cars magazine, reported damages and defects of the cars in the market. These informations were useful for everyone who wanted to buy a car, and for automakers also, so they could find assembly line mistakes to improve their vehicles and give a better product.
About Tempra, few damages of series were reported, but some defects that followed the car during its lifetime. First to be reported was a small water infiltration through the windshield gasket, plague that had once involved other Fiat's vehicle, especially Alfa 33, which in rainy condition used to carry a worrying quantity of water on board. Tempra's case was reported from 1990–92 and was solved with a higher quantity of glue in the assembling, and in fact the problem totally disappeared.
