About: Lotus 30

An Entity of Type: automobile, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The Lotus 30 was a racing automobile, Colin Chapman's first attempt at a large displacement sports car racing machine following the success of the more conventional tube frame Lotus 19,19b and Lotus 23., it was designed by Colin Chapman and Martin Wade, and built in 1964. The Lotus 30 was raced in British races such as , international races such as that allowed FIA Group 4 "Sports Car" class of racing machines, and more importantly, in Can Am series. These were before the recognition and creation of Group 5, 6 and 7 categories by FIA in 1966. This explains why Lotus 30 and 40 (the latter was built in 1965) came originally equipped with headlights, tail lights and a windshield wiper.

  • The Lotus 30 was a racing automobile, Colin Chapman's first attempt at a large displacement sports car racing machine following the success of the more conventional tube frame Lotus 19,19b and Lotus 23., it was designed by Colin Chapman and Martin Wade, and built in 1964. The Lotus 30 was raced in British races such as , international races such as that allowed FIA Group 4 "Sports Car" class of racing machines, and more importantly, in Can Am series. These were before the recognition and creation of Group 5, 6 and 7 categories by FIA in 1966. This explains why Lotus 30 and 40 (the latter was built in 1965) came originally equipped with headlights, tail lights and a windshield wiper. Notable for its curvilinear fibreglass body work and "pickle fork" backbone chassis first seen in the front engine Lotus Elan, On the 30 the layout was reversed and placed the engine behind the driver. Lotus engineer Len Terry was asked by Chapman to comment on the draft concept and considered it to be so flawed he refused to have anything to do with it. The Lotus 30 was powered by a 4.7 litre (289 c.i.) Ford V8 engine, the same type as used in the Ford GT40, mated to a 5 speed ZF syncromesh 5DS20 transaxle which was far more reliable than Colotti transaxle in 19B handling the V8 torque. It used 13 inch wheels and solid disc brakes on each wheel. The Lotus 30 was regarded as unsuccessful and / or dangerous but when everything was working and nothing broke, the car was incredibly fast. The inherent flaws of the engineering became evident as horse power requirements and tire technology of the period evolved and pushed the original design past its intended limits. The problems were mainly related to the torsional rigidity of the backbone chassis and materials available at the time, all of which resulted in chassis and suspension failures. Jim Clark laboured long with the car, and managed to prise some promising results with it before it was replaced with the Lotus 40. Equipped with 15in wheels and vented disc brakes as well as a larger engine, the 40 was just as recalcitrant as the 30. The most telling comment about these Lotus race cars was made by the American driver Richie Ginther. When asked what he thought of the new Lotus 40, Ginther, a lugubrious Californian, said, "Same as the 30 but with ten more mistakes". The effort was not a total loss as this chassis type proved to be perfectly acceptable for the lower powered Lotus Europa, and was used on the Esprit series cars with further development. (en)
  • La Lotus 30 era una vettura da competizione e rappresenta l'unico tentativo effettuato da Colin Chapman per realizzare una vettura per il Gruppo 7 o per le gare del campionato CanAm. La vettura venne costruita nel 1964 e il suo progetto si deve a Len Terry. La vettura era dotata di una carrozzeria in fibra di vetro dalle linee sinuose e di un telaio nel quale una pickle fork costituiva la struttura portante che era stato utilizzato per la prima volta sulla vettura a motore anteriore Lotus Elan. Sulla 30 la configurazione originale era stata rovesciata ed il motore era stato posto dietro al pilota La Lotus 30 era dotata di un motore Ford V8 da 4,7 l dello stesso tipo di quello montato sulla GT40 e del cambio sincronizzato a cinque marce prodotto dalla ZF. I cerchi erano da 13 pollici e con freni a disco su tutte le ruote. La Lotus 30 viene ricordata come una vettura dallo scarso successo e anche come una auto pericolosa. In ogni caso quando tutto funzionava e nulla si rompeva si dimostrò una vettura incredibilmente veloce. I limiti insiti nel progetto divennero evidenti come l'aumento della potenza e lo sviluppo della tecnologia degli pneumatici spinsero oltre i propri limiti il progetto. I problemi erano legati principalmente alla rigidità torsionale della struttura portante del telaio e ai materiali all'epoca disponibili che provocavano delle avarie al telaio stesso e alle sospensioni. Jim Clark impiegò molto tempo su questa vettura e cercò di ottenere alcuni risultati positivi prima che venisse sostituita dalla che utilizzava cerchi da 15 pollici e freni a disco autoventilanti oltre ad un motore di cilindrata maggiore. Purtroppo anche la Lotus 40 si dimostrò essere una vettura difficile come la 30 che andava a sostituire. Il più famoso commento su queste due vetture venne effettuato dal pilota statunitense Richie Ginther. Quando gli venne chiesto cosa pensasse della nuova Lotus 40 Ginther, un californiano pessimista, disse era simile alla Lotus 30 ma con più errori. Lo sforzo però alla fine non fu una perdita di tempo totale in quanto questo telaio si dimostrò perfetto per le meno potenti Lotus Europa e, una volta sviluppato, venne usato sulla gamma Esprit. (it)
