Para a \u00e9poca de 1976, a FIA introduziu uma nova categoria do Grupo 5, \"Carros de Produ\u00e7\u00e3o Especiais\", permitindo modifica\u00e7\u00f5es extensivas aos carros de produ\u00e7\u00e3o homologados nos Grupos 1 a 4 da FIA. O Deutsche Rennsport Meisterschaft (DRM), o antecessor do DTM, utilizou este regulamento de 1977 a 1981, at\u00e9 que a categoria foi abolida no final de 1982 a favor do Grupo B, mas os Gr.5 continuaram a competir no IMSA GTX e noutros campeonatos nacionais de carros desportivos durante mais alguns anos.<\/p>\n\n\n\n

Os regulamentos limitavam a largura normal da carro\u00e7aria, mas permitiam asas mais largas. Apenas o capot, o tejadilho, as portas e as embaladeiras deviam permanecer inalterados. Tudo o resto era deixado ao crit\u00e9rio do engenheiro. Em suma, os construtores tinham total liberdade para brincar com a aerodin\u00e2mica, utilizar materiais ultra-leves ou instalar enormes turbocompressores. Um excelente exemplo \u00e9 o monstruoso Ford Capri Zakspeed, cuja vers\u00e3o twin-turbo de 1,7 litros, alimentada por um turbo KKK, podia debitar 600 cv. Para um autom\u00f3vel com menos de 800 kg, esta pot\u00eancia conferia-lhe um desempenho excecional.<\/p>\n\n\n\n

Um projeto alem\u00e3o<\/h2>\n\n\n\n

Muitos fabricantes tentaram a sua sorte, com diferentes graus de apoio da f\u00e1brica: A Lancia com o Stratos e depois com o Beta Monte Carlo, a BMW com o 320 Turbo, a Porsche com o 935, a Lotus com o Esprit e at\u00e9 a Toyota com o Celica! E todos eles, Alfa Romeo<\/a> tamb\u00e9m fez algumas apari\u00e7\u00f5es! Uma vers\u00e3o Grp.5 do Alfetta GTV foi desenvolvida para o DRM e correu l\u00e1 entre 1979 e 1981. O projeto foi uma colabora\u00e7\u00e3o entre a Isert Motorsport (que construiu o carro), a Sachs Racing (suspens\u00e3o) e o Dr. Schrick, que contribuiu para o design do motor. A Alfa Romeo Alemanha financiou todo o projeto, embora n\u00e3o estivesse oficialmente envolvida.<\/p>\n\n\n\n

400 cv de um motor de 1,3 L!<\/h2>\n\n\n\n

O motor \u00e9 um motor de curso curto de 67,5 mm, 81 mm de di\u00e2metro, baseado numa cambota GTA 1300 e numa cabe\u00e7a de cilindro de 4 v\u00e1lvulas. Com a sua cilindrada, o carro era eleg\u00edvel para a Divis\u00e3o 2 do Grupo 5. A primeira vers\u00e3o de teste tinha transmiss\u00e3o por corrente e foi convertida para transmiss\u00e3o por correia em 1981. Este carro foi tamb\u00e9m o \u00fanico DRM a experimentar a inje\u00e7\u00e3o eletr\u00f3nica de combust\u00edvel, antes de ser finalmente equipado com a inje\u00e7\u00e3o mec\u00e2nica Kugelfischer. Nesta configura\u00e7\u00e3o, o Alfetta GTV desenvolvia cerca de 400 cv, o que era certamente impressionante, mas muito longe dos 600 cv alcan\u00e7ados pelo Ford Capri Zakspeed e o Porsche 935!<\/p>\n\n\n\n

Tinha uma suspens\u00e3o traseira 4-link (como o Ford Escort e o Capri da \u00e9poca) com uma barra anti-bloqueio. Este GTV Gr5 \u00e9 uma verdadeira manta de retalhos da Alfa, com trav\u00f5es traseiros do Rallye Alfetta Gr.4 e pin\u00e7as retiradas do Tipo 33.<\/p>\n\n\n\n

Um olhar estranho, ainda mais em 1981!<\/h2>\n\n\n\n

Todos os pain\u00e9is exteriores da carro\u00e7aria s\u00e3o de pl\u00e1stico, com exce\u00e7\u00e3o do tejadilho. Para al\u00e9m das vias mais largas, a extremidade dianteira apresenta um enorme spoiler, que tem uma semelhan\u00e7a impressionante com o do Grupo B Quattro S2 lan\u00e7ado alguns anos mais tarde. Este spoiler enorme e desajeitado valeu ao GTV a alcunha de \"p\u00e1 de neve\".<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Mais tarde, o design evoluiu de forma estranha, com o GTV a receber uma nova frente com o aspeto de um Porsche 935. Ao mesmo tempo, a pintura branca (que, de acordo com algumas fotos, tamb\u00e9m era predominantemente amarela) mudou para vermelho! Produzido em 1981, este kit tinha um nariz mergulhante e far\u00f3is bastante semelhantes aos da bomba alem\u00e3. O resultado foi altamente question\u00e1vel, al\u00e9m de tirar a sua identidade carater\u00edstica! Apenas um pequeno Scudetto nos lembrava que se tratava de um Alfa Romeo nesta bizarra roupagem.
\u00a0
N\u00e3o tendo conseguido obter resultados significativos (nem terminar uma \u00fanica corrida, devido a um sistema mec\u00e2nico debilitado pelos 400 cv e pelo turbo), o carro foi retirado no in\u00edcio de 1982, ap\u00f3s o desaparecimento da DRM. Permaneceu fora de servi\u00e7o durante muito tempo, no seu estado original, antes de ser restaurado nos \u00faltimos anos ap\u00f3s v\u00e1rias mudan\u00e7as de propriet\u00e1rio. A \u00faltima vez que ouvi falar dele, estava em Portugal!\u00a0<\/p>","protected":false},"excerpt":{"rendered":"","protected":false},"author":8,"featured_media":45783,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_sitemap_exclude":false,"_sitemap_priority":"","_sitemap_frequency":"","footnotes":""},"categories":[22],"tags":[516],"class_list":["post-45776","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-alfa-romeo","tag-alfa-romeo-alfetta-gtv","generate-columns","tablet-grid-50","mobile-grid-100","grid-parent","grid-33"],"acf":[],"yoast_head":"\nCette Alfa Romeo Alfetta GTV allemande d\u00e9velopp\u00e9e pour le Gr5 atteignait 400 ch... avec un moteur 4 cylindres 1.3L !
