No, I'm pretty sure those had "Neo VVL". It didn't have fully variable control of the intake valve. Instead it had an adjacent "aggressive" cam lobe which used oil pressre to engage the aggresive cam follower at a set RPM. Just like Honda's system. Still not sure how they got around the patents.

VVEL didn't come along til much later.
