Marka aan furno daboolka, suurtagal maaha in la dareemo. Meesha shidaalka afar-dhululubo ee khadka-line (1.8 l) in tan BMW 5 Taxanaha E28 1987 waa in aan haysanaa, waxaan ka helnay mishiinka naaftada lix-dhululubo oo khadka ah oo ka yimid saaxiibkii ay xafiiltamaan ee Mercedes.
Waa in aan is waydiinnaa waxa nagu kalifay in aan dhigno OM 606 block (1993-2001) ee astaanta Stuttgart ee nuqul ka mid ah astaanta Munich, laakiin dareenkayagu wuxuu si dhakhso ah u leexiyay qiimaha awoodda la xayeysiiyay: 500 hp!
Marka loo eego taariikhda, OM 606-kii asalka ahaa waligiis ma arag in ka badan 177 hp si loogu dhimo dhaqdhaqaaqa lixda pistons iyo 3.0 l ee awoodda - sidee ku timid mashiinka naaftada ee lagu rakibay BMW 5 Taxanaha E28 ayaa ku dhawaad saddex jibaarmay awoodiisa?
Isbeddelku ha bilaabo
Sida laga soo xigtay iibiyuhu, mishiinka ayaa si dhab ah wax looga beddelay: hadda waxaa lagu qalabeeyaa Borgwarner S300 turbocharger (ilaa cadaadiska 3 bar), wuxuu leeyahay bamka shidaalka cusub, nidaamka qaacidda gaarka ah (76 mm) ee birta aan fiicnayn, radiator cusub. (laga bilaabo M3 E36) iyo albaabka qashinka dibadda ah.
Si loo wareejiyo dhammaan awoodda Naaftada tan asphalt, gudbinta BMW 5 Series E28 sidoo kale waxay ahayd in lagu beddelo mid kale. Doorashadu waxay ku dhacday sanduuqa gear-ga ee lixda-xawaaraha leh ee Mercedes-Benz C-Class 220 CDI (sanad aan la cayimin), laakiin ay weheliso xirmo la xoojiyey oo ka yimid Sachs iyo matoorka-matoorka-matoorka-loo-dhismay isbeddelkan.
Daawada gudbinta ayaa sidoo kale laga abuuray xoqan iyo dabada danbe ee 5-taxane waxaa jira kala duwanaansho is-quful ah (oo leh saamiga 2.93: 1). Dabcan, si ay ugu habboonaato silsiladan kinematic-ka bidca ah ee "bimmer", waxay ahayd lagama maarmaan in la abuuro dhejisyo gaar ah oo loogu talagalay mishiinka iyo gudbinta, aad u badan oo la xoojiyay - la yaab ma leh ...
Dabiici ahaan, chassis-ka ayaa sidoo kale dib loo cabiray si loo maareeyo waxaas oo dhan: nidaamka bareegga wuxuu ka yimid BMW 540i (E34), xirmooyinka gambaleelka hadda waa polyurethane (Polybush) iyo qoyaanka hadda waxaa gacanta ku haya qaar ka mid ah coilovers BC.
"Si cabsi leh u degdega"
Sida laga soo xigtay milkiilaha, inkasta oo dabeecadda "Frankenstein Monster" in abuurkani yahay, wuxuu yidhi "waxay si fiican u qabataa, waxay leedahay dabeecad cajiib ah oo aad u degdeg badan".
Isku soo wada duuboo, dharka suubban ee 518i ayaa lagu hodmay xirmada jirka ee M535i, taayirrada BBS-dahaarka budada ah iyo shaqada jirka ayaa si cusub loogu rinjiyeeyay casaan dhalaalaya oo aad ka arki karto sawirrada.

Xayawaankan cajiibka ah ee soo jiidashada leh ayaa laga helay UK, waa la baadhay (MOT) wuxuuna ku joogaa ebay qiimo dhan £16,500 (qiyaastii €19,260) ilaa hadda cidina ma soo bandhigtay wax ka sarreeya qiimaha kaydka.
Mulkiilaha/iibiyaha ayaa sheegay in uu hore u daboolay 16 kun oo kilomitir ah BMW 5 Series E28 oo ku qalabaysan mishiinka "diabolic" Mercedes-Benz Diesel, tan iyo markii la bedelay iyo, sida uu sheegay, "waa waalan". Si kastaba ha ahaatee, baabuurka laftiisa "eedey" qiyaastii 300 kun oo kilomitir.
