Lancia Beta Trevi car details
1980 to 1984
Body versions :
The Lancia Beta Trevi as from 1983 just Lancia Trevi is a four-door notchback sedan of the Italian car manufacturer Lancia , which was produced from 1980 to 1984. The Trevi was derived from the eight years previously presented hatchback Beta Berlina , with whom he shared the technology and much of the body. In 1982, with the top-of-the-line Trevi Volumex, Lancia introduced a Roots Blower Chargingto increase performance, which made the model the first mass-produced road vehicle with mechanical boost since World War II. The Beta Trevi VX Bimotore was a unique piece designed for the automobile sport, which was factory fitted with two supercharged engines.
Lancia Beta Trevi History
The Beta Trevi is closely related to the hatchback sedan Beta Berlina. The Berlina was the first Lancia model that was redeveloped after the acquisition of the company by the Fiat Group . She replaced the Lancia Fulvia . The development time of the beta was just over two years. Lancia took over many mechanical parts from Fiat - including the engines - but also from the former cooperation partner Citroën , especially the gearbox. The body shape of the Beta Berlina did not come from Lancia; it was born in Fiats Centro styles, A characteristic feature was the hatchback body with small, flapped below the rear window boot lid. She found herself later in the also developed in cooperation with Citroën Lancia Gamma again. Lancia derived from the beta structure over the years a whole model family, which included a notch coupe, a Kombicoupé ( HPE ) and an open model with Targadach ( Spyder ). Each designed by Pininfarina bodies were similar to each other, but had no common parts with the Beta Berlina. The last variant of the beta theme appeared in March 1980, a notchback version, which formally linked to the Beta Berlina.Among the attempts to make the beta series of attractive, also included a five-door station wagon, which, however, was only built as a single piece.
The additional designation Trevi, which became from 1983 sole model designation, does not refer, as is occasionally suggested, to the Roman Trevi fountain . Rather, the word is a summary of the Italian term Tre Volumi and describes the body structure consisting of three separate spaces (engine, passenger and trunk). Parallel to the development of the Trevi considered Lancia, also the hatchback Gamma a sister model with a classic notchback to side. The Gamma Tre Volumi created a single prototype that still exists today. A serial production did not materialize.
The body of the Beta Trevi was designed by in-house designers; Detailed work contributed to Pininfarina. As far as the rear doors, the Beta Trevi was similar to the Berlina. At the backpack-like trunk, the waistline continued horizontally. The high, angular rear construction was often perceived as inharmonious or inelegant; particular, the multi-part paneled C-pillar was the criticism. At the rear roof edge was integrating a separation edge above the rear window.
A special feature of the Beta Trevi was the dashboard, which deviated from those of all other beta models. At the Trevi, it was designed by the Milanese architect and industrial designer Mario Bellini , whose work had hitherto had no relation to the automobile. Bellini had designed a slightly curved unit of colored plastic. were let Therein about 30 round wells in which switches and individual ads were located. Bellini's dashboard was criticized almost universally; especially the complexity of the layout of the displays and controls was criticized. It was mocked in the press as a "rock with holes drilled in it", "cave landscape", "Swiss cheese" or "Gruyère à la Fiat".Many commented that this futuristic design is in contrast to the more conventional exterior.
The Trevi had a self-supporting body . The chassis corresponded to that of 1971 and 1972 constructed under the direction of Sergio Camuffo Beta Berlina. Front and rear, the wheels were hung individually . At the front, the car had MacPherson struts and wishbones with stabilizer , the rear was as in the Beta Berlina, the so-called Camuffo rear axle with wheel-guiding struts, two wishbones and a trailing arm installed.The engine was transversely installed in the front of the Trevi; he drove the front wheels. Lancia offered several different engines with carburettors, intake manifold injection and mechanical boost.
The Trevi was available with various versions of the so-called Lampredi four-cylinder , which had appeared in 1966 in the Fiat 124 Coupe and gradually became the standard engine of the mid-size vehicles of the Fiat Group. From the beginning it was also incorporated in the Beta Berlina and in the other variants of the Beta. The headed by Aurelio Lampredi motor developed had a block of gray cast ironand was equipped in all displacement versions with two overhead camshafts, which were driven by a toothed belt. As the smallest model Lancia offered the Trevi in many markets a 1.6-liter version with 74 kW (101 hp) on; above him was a variant with 2.0-liter displacement and 85 kW (116 hp) settled. Both engines were equipped with double carburettors from Weber . The larger engine was available from 1981.
For model year 1982 appeared as a new top model of the Trevi 2000 Volumex. With him, the engine was charged with a Roots compressor. The Trevi Volumex was the first mass-produced car with mechanical charge since the end of World War II . Later, the engine was also used in other models of the Fiat Group. Apart from the Beta Coupé and the Beta HPE, the Fiat Argenta and the Fiat Spidereuropa were also equipped with the supercharged engine at times . There are various approaches to the genesis of the Trevi Volumex. About press releases Lancia tried to establish the compressor as an alternative to turbocharging, and promised itself of a performance increase without the turbo-drawbacks, which is primarily the so-calledmTurbo hole was meant. However, some sources believe that the trigger was for the development of the compressor motor in reality in car racing: Looking for a powerful engine concept for the rallying cars Lancia 037 Aurelio Lampredi had come to a supercharged 1,981th In order to justify the development costs of such an engine, it was necessary to develop a street version for sale in larger quantities.
The installation of the compressor required numerous changes to the details of the four-cylinder engine and its surroundings: the compression was reduced, the pistons were redesigned, the camshafts and valves had to be adapted and the intake system changed. Added to this was a modified exhaust system and a new cooling system. In many cases, it was criticized that Lancia is not the compressor motor with the already available manifold injection coupled, but with the conventional Weber carburettors. The performance of the engine was Volumex (135 hp) indicated with 99 kW.
In June 1983, Lancia introduced the second series of the sedan, which was no longer beta, but only Trevi. The main changes concerned the drive technology and here especially the gear ratio; they had the goal to reduce consumption. The carburetor version of the 2.0-liter engine accounted for. Externally, only a few trim parts changed.
In 1984 Lancia constructed the Trevi Volumex Bimotore , which was equipped with two equally sized supercharged engines. The occasion was the increasing dominance of four-wheel drive vehicles in the former Group B , in which Lancia had fallen behind with the rear-wheel drive 037 after initial successes. Since early 1984, Lancia's engineers worked on a four-wheel-drive successor to the 037, which was based on the compact delta and when Delta S4 was used successfully from 1985. The engineers were already looking for a way to explore the basics of four-wheel drive during development S4. The rally driver and Abarth test driver Giorgio Pianta came up with the idea of equipping a production vehicle with two engines for test purposes, each of which was supposed to drive one axle: this would make it cheap to drive a four-wheel drive.The basis for the project was a standard Trevi Volumex with the 2.0-liter supercharged engine. The front-wheel drive remained unchanged. In the passenger compartment, a second drive block and the front suspension were installed instead of the rear seat, wearing a specially designed subframe. The transversely mounted engine drove the rear wheels. Initially, a drive-by-wiremotor control was provided; However, it did not work properly. Instead, the Lancia engineers resorted to Bowden cables , which improved the response of the second engine but still did not solve all the problems. There were also problems in cooling the rear engine.
The Bimotore was a pure test vehicle. Giorgio Pianta described the car as a "rolling laboratory". A rallye was not planned and did not materialize.
From 1980 to 1984, Lancia produced all engines together, 40,628 Trevi. 3844 cars had the Volumex engine.
