honda developed vtec by racing in f1 (dominating f1 for the late 80s [won 15/16 races with the late aryton senna])...it was the first company to bring such technology to production cars...now most mfgrs have or are working on a similar system...i wouldn't knock honda since this company was based on racing to improve its production vehicles...honda also developed cvcc technology out of racing b/c its engineers who were fumbling with it while working in the formula1 rotation found it reduced emissions significantly
