RE: H3 vs H3 Alpha

Every SUV i've had makes that noise at cold start up. But i got used to it. I thought CWS was describing some other kind of sound that i never heard.

ORIGINAL: CWS

It DID make a hell of a noise when I first started her up and drove off. Sounded like my wife was in the back seat with the home vaccuum cleaner - what an ungodly noise. Didn't seem to do that once warm, but on a cold start OMG. Do they all have that idiosyncracy ?

The noise isbecause of varriable valve timing. It runs like that briefly at startup to heat up the cats.
