The Lancia ECV (standing for Experimental Composite Vehicle) was a prototype Group S rally car developed by the Italian manufacturer Lancia to replace the Lancia Delta S4 in World Rally Championship competition for the 1988 season. However, Group B as well as Group S cars were banned from competition by the FIA in late 1986 due to safety concerns and the ECV never raced. Lancia instead developed the Group A Lancia Delta.
The car originally produced over 600 horsepower (448 kW) from a 1759 cc twin-turbocharged engine. This engine, christened Triflux, was built in an unusual fashion; the valves were crossed (for each side of the cylinder there was an intake and an exhaust valve), so that the two turbochargers could be fed with two separate manifolds. A single manifold carried the intake air (hence the name, from the three separate air ducts). However, Group S rules would have artificially limited the car's output to 300 hp (224 kW) to limit speeds.
The car featured a new Martini colour-scheme, replacing the S4's white bodywork with red-based scheme. Lancia used the new scheme on its competition cars in 1987.
The Restored ECV1, rebuilt from the original parts, was displayed at the Rally-Legend Event on 7-8-9 October 2010 in San-Marino, by the owner, Giuseppe Volta. An original TriFlux engine has been re-prepared, with the help of the original designer, Ing. Claudio Lombardi, and modern Turbo-engine preparation expert, Claudio Berri. A website has been opened to note the occasion.
Despite the cancellation of Group S, Lancia improved the ECV with the ECV II. The ECV II carbon-fibre chassis was that of the ECVI. The designer of the car is Carlo Gaino of Synthesis design . The ECV II concept car was more compact and featured improved aerodynamics. The ECV II had the same engine and chassis but a different paint scheme.
