I beleive on the V8 in the E65 745Li (the current 7 series body style).. so around 2002 or so?I don't know which other BMW engines feature Valvetronic.
None of the M engines do - BMW has stated that thus far, Valvetronic isn't responsive enough for their M car engines - which all rev to 8000+ rpm now
(8000rpm for the M3 / Z4M, and 8300 for the M5/M6)sounds to me like its real high performance...
Back to the point
- GSR's car is crazy fast and has too many traction problems to run real fast or race on the street, i think the ricers are jealous
- cept honda, makers use VVT for driveability
- your all ricers

According to BMW, Valvetronic engines have a 15% power (or 15% mileage, depending on which way you swing) advantage over the equivalent motor without valvetronic.
A 15% power boost and complete elimination of the throttle assembly is nothing to sneeze at.
M engines (except the S50 from the USA E36 M3) run ITB's anyhow. IIRC, it takes 200ms for the valvetronic eccentric to adjust through the full range of motion. For most people, that sort of latency is acceptable (hell, most people drive automatics), but for the motorsport engines, BMW apparently decided it was not.
If you're knocking the technology because in its very first iteration, BMW opted not to put it on some of the highest rated, highest performing stock engines in the world, that's cool, but I wonder what automotive engineers would say about your engine designs ?
If you're just being "clever", that's cool too
Since you're being argumentative - how is that honda doesn't use VVT for drivability? Why not just run the hot cam profile all the time?

I never said anything about V-T-E-C in this thread... other than the fact that it is superior in performance to most if not all of the other car companies Variable Valve Timing attemptsLike i menitoned pages and pages ago you really need to learn hands on about this stuff not read about it on the internet. Last time i checked this thread was about VVTi not ****.

Nick, Highlight the whole first post. There is a secret message under it written in white... this whole thread was a joke bringing back the VTE( talk. LOL@ everyone in this thread, including myself...I believe that was stated in the third post of the thread....
You are now 4 pages knee deep in your own retardedness.
