Nice To Know, Bottje !!!

[Eggybee]

Is dit inmiddels adequaat opgelost, of slechts opgelapt?

Ik ben blij dat ik zo'n betrouwbare S50 heb

[Edwin]

ehhhh, ik denk dat ik de 30e niet mee ga

[Botty]

Ook leuk, een kijkje in de fabriek in Steyr (nooit geweten dat daar de 6 cilinders werden gebouwd), Oostenrijk:

http://www.bmw-werk-steyr.at/

Vooral de "Virtuelle Werksführung" is leuk. Op een gegeven moment kan je onderaan doorklikken op de diverse afdelingen van deze indrukwekkende motorenfabriek.

Inderdaad, die mis ik ook. Hier een andere opsomming gevonden, specifiek Z3: http://www.shiraz.nl/bmw/z3/z3-m.htm

Ik mis ook de M-versie die de US kreeg, wat was daar de motorcode ook alweer van? Staat overigens zo een op mobile.de of was het nou autoscout.de?

Ik weet nog wel een gebruikte M54B30 te koop voor weinig, just in case

Ahum: The M54B30 was on the Ward's 10 Best Engines list for 2001 through 2003 ;)

[Davids Z3]

Dat is eigelijk een soort van vrouwen uitvoering van de M met heel wat minder vermogen...

Dat is een S52, staat op mobile.de

Moet de "pussy"-versie voorstellen inderdaad....

Zal wel heeeleemaal volhangen met allerlei vervelende emissiebeperkende snorkels

Overigens bestaan er ook leuke motoren voor specifieke markten. Zo is er een E30 voor Italië ontwikkeld met een 2L motor van de 4 cilinder M3, de 320 iS. Uit 2 liter haalt die 192 pk. Behoorlijke wolf in schaapskleren. Met zo'n mooie grote M op het kleppendeksel ;)
