The Lancia LC2 (sometimes referred to as a Lancia-Ferrari) was a series of racing cars built by Italian automobile manufacturer Lancia and powered by engines built by their sister company Ferrari. They were part of Lancia's official factory-backed effort in the World Sportscar Championship from 1983 to 1986, although they continued to be used by privateer teams until 1991. They were also the company's first car meeting the FIA's new Group C regulations for sports prototypes. More powerful than its primary competitor, the Porsche 956, the LC2s were able to secure multiple pole positions during their three and a half seasons with the factory Martini Racing squad. However, deficiencies in reliability and fuel consumption hampered the LC2's efforts for race wins against Porsche. LC2s earned three race victories over their lifetime in the hands of Italian drivers Teo Fabi, Riccardo Patrese, Alessandro Nannini, and Mauro Baldi, as well as German Hans Heyer and Frenchman Bob Wollek. ==Development== In 1982, the new Group C regulations were introduced to the World Championship. This rule set required teams to use coupé-style cars that had to be able to meet a fuel economy standard mandated at for every of fuel.〔(【引用サイトリンク】 An Encapsulated History of Sports Car Racing )〕 The Lancia LC1, which had been built to the older Group 6 regulations, initially competed in 1982, but had to be replaced in order for Lancia to earn constructors' points in the World Championship, now open to Group C cars only in 1983.〔(【引用サイトリンク】 Lancia LC1 Group 6 Spider 1982 ) 〕 Besides the fact that the LC1 had an open-cockpit, the turbocharged straight-4 Lancia engine it had used was not capable of achieving the fuel economy necessary in the new Group C regulations, requiring Lancia to also seek a new powerplant.〔(【引用サイトリンク】 Lancia LC2 )〕 Under the direction of Cesare Fiorio, Lancia began to work on the LC1's replacement. Lancia lacked a production engine large enough to base a racing engine on, leaving the company to turn to outside sources. Since Lancia were owned by the Fiat Group, they were able to seek the assistance of fellow Fiat company Ferrari. Ferrari allowed Lancia to adapt the new naturally aspirated four valve V8 which had been introduced in the Ferrari 308 GTBi QV in 1982.〔 The engine was reduced in capacity to 〔 and two KKK turbochargers were added to help the engine provide the fuel economy and power necessary.〔 The specific engine displacement was chosen because of the possibility of using the same engine in the North American CART series.〔 The engine was initially connected to a Hewland five-speed manual gearbox, which was replaced by an Abarth-cased unit in 1984. Design work on the chassis was split between Italian specialist racing car manufacturers Abarth and Dallara,〔 the latter of which built the aluminium monocoque and the kevlar and carbon fibre bodywork in their factory. The LC2 featured a large intake for the radiators in the center of the nose of the car just as the LC1 had,〔(【引用サイトリンク】 Cars & Models Lancia LC2 )〕 unlike the contemporary Porsche 956s which drew all their air from behind and to the sides of the cockpit. This air was also directed through the side bodywork to feed the intercoolers for the turbochargers.〔 Inlets for the rear brake cooling ducts were also integrated onto the side bodywork of the car, immediately behind the doors. At the rear, a pontoon-style design was adapted to the fenders with the large wing bridging across the pontoons. The rear diffusers exited between the pontoons and underneath the wing.〔〔 The LC2s were modified over their lifetime, with a multitude of modifications being made each season to the cars' aerodynamics, including adapting brake duct inlets beneath the headlights. The Ferrari V8 was modified in 1984, bringing the displacement back up to 3.0-litres in an attempt to increase reliability and horsepower while improved engine electronics from Magneti Marelli allowed the larger engine to use the same amount of fuel as the previous version.〔 In total, seven LC2s were built under the direction of Lancia, while a further two were built for Gianni Mussato without official backing after the program had ended. After the program had ended, Abarth acquired an LC2 and fitted it with the 3.5-litre Alfa Romeo Tipo 1035 V10 engine from the Alfa Romeo 164 Procar, and developed it under the project name SE047. The SE047 was an early development of the Alfa Romeo SE 048SP project in 1988. The SE047's engine was ultimately not utilized in the later stages of the SE 048SP development. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lancia LC2」の詳細全文を読む スポンサード リンク
