Ukubuyekezwa okusetshenzisiwe kwe-Holden Commodore: 1985

Igama elithi Peter Brock liyohlala lifana nelithi Holden. Umgijimi omkhulu ongasekho waqinisa ubudlelwano bakhe no-Holden ngochungechunge lokunqoba kwemijaho ngeminyaka yawo-1970, futhi uyohlale ekhunjulwa njengeqhawe lika-Holden. Akukaze kube nesibopho phakathi kuka-Brock no-Holden kunamandla kunasekuqaleni kwawo-1980, lapho u-Brock esungula inkampani yakhe yezimoto futhi ekhiqiza ulayini wezimoto zokugijima zomgwaqo ezisekelwe ku-Holden Commodore. Kube nama-Commodores amaningi amahle kakhulu anebheji ye-HDT, kodwa enye enkulukazi kwakungu-Bluey, ozalelwe umjaho we-Group A Commodore eyakhelwe emithethweni emisha ye-International Group A yomjaho ngo-1985.

BUKA IMFANELO

Ngo-1985, umjaho wezimoto zabagibeli wase-Australia wathatha indawo yemithetho yasekhaya eyayikhona kusukela ekuqaleni kwawo-1970 ngefomula entsha eyakhiwe eYurophu. Imithetho yendawo yasusa umjaho wezimoto emijahweni yasemgwaqweni, yanikeza abakhiqizi inkululeko ebanzi yokuguqula izimoto zabo zesitoko ukuze zilingane nethrekhi, kodwa imithetho emisha yaphesheya kwezilwandle ibinomkhawulo futhi yethula kabusha imfuneko yokukhiqiza okungenani uchungechunge olulinganiselwe. izimoto zomjaho.

I-VK SS Group A bekungeyokuqala yalezi zimoto ezibizwa nge- "homologation" ezikhethekile ze-Holden ezakhiwe ngesikhathi seQembu A. Yayisekelwe ku-Brock's Commodore HDT SS, yona ngokwayo esekelwe ku-Commodore SL, imodeli elula kunazo zonke kulayini we-Holden. Wonke ayependwe ngokuthi "Formula Blue", yingakho isiteketiso esithi "Blueies" ngabashisekeli baka-Brock, futhi afaka igrile "yebhokisi lezinhlamvu" ephefumulelwe u-Brock kanye nekhithi yomzimba ebolekwe kakhulu kubagijimi bangaphambili be-Brock Commodore.

Ngaphakathi, ibinoqweqwe olukhethekile oluluhlaza okwesibhakabhaka, isethi egcwele yezinsimbi, kanye nesondo lokushayela le-Mono lesikhumba.

Ngaphansi kwe-Group A, ukumiswa kwamiswa ngendlela efana neka-Brock SS Group Three, nama-Bilstein gas struts and shocks, nama-SS springs. Njenge-SS evamile, yayinebha yokudonsa yangemuva engu-14mm, kodwa yayinebha enkulu kakhulu engu-27mm ngaphambili.

Amabhuleki akhishwe kwi-Brock SS Group Three kanti amasondo enziwe ngamasondo angu-16×7" HDT alloy asongwe ngerabha engu-225/50 Bridgestone Potenza.

Ngaphansi kwe-hood bekukhona i-4.9-litre V8 Holden elungiswe ngokukhethekile. Ngaphansi kwemithetho ye-Group A, i-Commodore ngabe ihlawuliswe kakhulu ngenxa yesisindo esiningi ukube igijime ngosayizi ojwayelekile we-Holden V8, ngakho ukukhishwa kwehliswe kusuka ku-5.044L kuya ku-4.987L ngokunciphisa i-stroke kuze kube yi-squeak ngaphansi kwenjini engu-5.0L. . umkhawulo.

Enye enye injini idonse kakhulu ulwazi luka-Holden lomjaho wangaphambilini futhi ihlanganisa namakhanda esilinda alungiswe injini engu-Ron Harrop, izinduku zokuxhuma ezisindayo ze-L34, ama-valve springs e-Chev/L34 esindayo, izingalo ze-Crane roller rocker, i-Clumsy Crane camshaft, i-four-barrel Rochester carburetor, amachweba afanayo kanye ne-exhaust, uchungechunge lwesikhathi lwemigqa ekabili, i-flywheel engasindi, ama-HM manifolds kanye nama-muffler ka-Lukey.

Ifuqa amandla angu-196kW ku-5200rpm kanye ne-418Nm ku-3600rpm, 19kW ngaphezu kweHolden V8 yetorque efanayo. Kuphinde kwaba injini evuselelayo, futhi u-Holden uphakamise umugqa obomvu ngo-1000 rpm ngaphezu komkhawulo wenjini ojwayelekile ongu-5000 rpm. Okuhambisana nenjini entsha iHolden M21 edonsa ngamagiya amane ashintshwayo.

I-VK Group A eyahlolwa ngaleso sikhathi yashesha yafinyelela ku-100 km/h emizuzwaneni engaba yisikhombisa futhi yahlanganisa i-sprint yamamitha angu-400 isuka kuma nse ngemizuzwana engu-15. Yayishesha ngesikhathi sayo, iphathwa futhi ibhuleki kahle kakhulu, futhi ibukeka iyinhle ngokuba khona kuka-Brock ngendlela ecacile emgwaqeni.

Ngaphansi kwemithetho kaGroup A, uHolden bekumele akhiqize izimoto ezingu-500 ngaphambi kokuthi agijime. Zakhiwe kulayini wokukhiqiza we-Holden zabe sezithunyelwa efekthri ka-Brock e-Port Melbourne lapho zaqedwa khona.

ESITOLO

Ngaphansi kwesikhumba sika-Brock, lena i-commodore ka-Holden futhi ingaphansi kwezinkinga ezifanayo nama-commodores avamile. Ngaphansi kwesivalo, bheka ukuvuza kukawoyela eduze kwenjini nesiteringi samandla. Ngaphakathi, bheka okugqokwayo ku-trim eluhlaza okwesibhakabhaka njengoba ingagugi kahle futhi uhlole ideshibhodi ukuthi ayinamifantu yini ngenxa yokuchayeka elangeni. Okuhle wukuthi abanikazi abaningi bayazazisa izimoto zabo futhi bazinakekele ngendlela efanele. Okubaluleke kakhulu ukwenza isiqiniseko sokuthi lena imodeli yeQembu A langempela, hhayi inkohliso.

NGENGOZI

Ezokuphepha zazisanda kuqala ngesikhathi kwethulwa i-VK Group A, ngakho yayingenazo izinhlelo esezithathwa kalula. Ayengekho ama-airbag noma ama-ABS, futhi ukulawula ukuzinza bekukude namaqiniso.

Lindela ukubona izibalo zomnotho ku-15-17 l/100 km, kodwa kuya ngesitayela sokushayela.

• Ubuqiniso

• Ukusebenza kwe-V8

• Ukubamba okuphendulayo

I-BOTTOM LINE

Imoto yemisipha yase-Australia ebabazekayo eyakhiwe yinganekwane yangempela yemidlalo yezimoto.
