: A very early model of the 2.8L engine first used in the Z3 in 1997 proved to be inefficient in the United States..it was made from aluminum and had a problem with the fuel in the US reacting with it. They switched it to cast iron. The new 2.8L engine that has Double VANOS is still cast iron, but it has aluminum sleeves now.
from what we have heard on here the preproduction models (that at least one person got) were all aluminium (maybe they accidently put a Euro engine in an american bound car???...anyway the Z3 2.8 was the first BMW to use the aluminum block with cast iron sleeves (starting with 97 production, not new for the 99s)
