Quick Question

What does the "s" in 3.0si stand for?

SLAMMING! :NOADD:

Ha, just joking. I really don't know. Interesting question though. I would assume on the 4.8 that it stands for Sport.

Its just odd that its in the 3.0 but not 4.8. I tried looking at the brochure but didnt really see anything. Oh well.

Hmmm. The brochure from the front page here and BmwUsa.com only list the 3.0si and 4.8i.

The s stands for sport, but what it means in the context of the 3.0 is that the E70 has a higher output 3.0 engine that the last E53 3.0, as it is a newer generation Valvetronic engine. There isn't an E70 3.0i, which means that the s is somewhat redundant.

The same s designation is used on the X3 3.0i and X3 3.0si (although the si isn't available in the US), to designate a higher output version of the same displacement engine.

With the E53, the 4.8 was an s, whereas with the E70 the 4.8 is not an s.

It's about time the auto makes drop the "i" designation now. It means "fuel injected", doesn't it? Are there any new cars still being made with carburetors these days?

Nah. It'd be really awkward seeing a BMW trunklid with only "335".

Woah thanks for that explination! So in other words, the "s" for the new E70 3.0 stands for "special." Of course in German I am sure there is some other long word to use.

How about 335TT for Twin Turbo?
