To quote my friend SAN (post #2, above):
huh???? what are you talking about???
1) There is no 3.5l (presuming you mean 3.5 litre) 35 is a marketing designation, the 3.5 litre six disappeared from North America some time ago. Nice engine in a 535 and 735 though.
2) The final two digits haven't meant displacement for some time now. I recall the 318 in 1993 that went to 1.9 litres to gain torque; the 325 with a 2.3 litre engine; then the 328 3 litre, and the 325 3 litre in North America; culminating in the 'turbo factor' applied to the 3.0 and 4.4. Face it, it is all marketing, and they pick numbers based on what they sound like and look like on the butt of the vehicle. Possibly even because they have too many chrome insignias left over to use up.
3) I know I am going to regret asking this, but why would you divide 3.5 (even if it was displacement) by two? OK, because you did it above, even though it means nothing. Well then, 3.5 divided by 2 would be 1.75, not 1.25. Check your calculator, the battery may be flat.
4) If you wanted to divide by anything (??) why not pick cylinders, to get displacement per cylinder? At least it means something. 3.0 = 500 cc per cylinder, which for a V8 gives 4.0 litres (mmm, nice engine in the M3) and for a V10 gives 5.0 litres (mmm, nice engine in the M5, maybe there is a trend here).
What does all this mean? Absolutely nothing. Hope you are sharing around whatever you are smoking or drinking, it must be good stuff.
