First displayed at the Bologna Motorshow in 1986, the ECV1 (Experimental Composite Vehicle) was a composite technology concept car testing the use of carbon, kevlar, thermosetting and thermoplastic resins, glassfibre and honeycomb in car production. It was also considered Lancia's prototype Group S car (a formula which never came to fruit). It was a further development of the S4, featuring the same basic design, with many of the components now made from composites, including the main, load bearing part of the body. Other composite parts included the wheels (8x16" wheels weighing only 6kg !) and the propshaft. It was powered by a 1759cc twin turbo (two KKK units) engine producing 600bhp @ 8,000rpm using a new design known as "triflux" where the two turbochargers were used sequentially depending on the engine speed. An overall weight of 930kg was achieved.
3 shoots of the interiors
my cat want his part XD
a important part of this car is the engine: the triflux,
but, what is a triflux??
The 1800cc power unit of the ECV1 & 2 was known as the triflux. This was due to the design which had one exhaust and one inlet valve on each side of the cylinder head, with the resulting twin exhaust manifolds each feeding one turbocharger. At low engine speeds one turbocharger exhaust was shut-off, forcing all the exhaust gases through one unit and thus providing good low speed performance. As the engine speed rose, the second turbocharger was gradually introduced, until at high engine speeds both turbochargers ran in parallel.
