Presented in June 1993, the second Evolution version of the Delta HF Integrale featured an updated version of the 2-litre 16-valve turbo engine to produce more power, as well as a three-way catalyst and Lambda probe. The addition of the catalyst did not penalise performance. Indeed, the Evoluzione II produced more power and torque than its predecessor, the Evoluzione I.
The engine developed a maximum power output of 215 PS (156 kW) DIN (against 210 PS on the earlier uncatalysed version) and maximum torque of 314 Nm (formerly 300 Nm). In order to underline the even more advanced engineering and performance of the 1993 version, the new Integrale was also given a cosmetic and functional facelift.
