Lancia ECV and ECV 2 Group S prototype rally car video
Lancia developed the ECV as a prototype Group S car to replace the Delta S4 for the 1987 WRC.
Due to some horrific accidents in 1986 Group B was canned by FISA, and so too was its would be successor Group S, which was to have been the replacement category in '87. Lancia had already built a prototype ECV with the KKK twin turbo engine developing around 600 BHP.
The car was unveiled at the Bettega Memorial Rallysprint in 1986 which was very much a display of what Turin and Claudio Lombardi were capable of. If Group S had gone ahead then the largely carbon fibre machine would of had to refine its power output to 300 BHP.
The ECV 2 was an evolution concept which would have used the same engine and other components in a more aerodynamic package. Both cars, however, would remain as stillborn projects and would never venture onto the special stages.
