I think so. We also have a variable length intake and low RPM intake accelerator (restrictor) flap when the engine is cold. It is supposed to reduce emissions by causing more swirl in the cylinders at low air flow.

Yup, the S-VT variant (if Wikipedia is right 
)
http://en.wikipedia.org/wiki/Mazda_MZR_engine
The MZR is Mazda's latest Straight-4 gasoline powered engine. The MZR family features a special long intake manifold for added torque, S-VT continuous variable valve timing, and a stainless steel 4:1 exhaust header.
S-VT, or Sequential Valve Timing, is an automobile variable valve timing technology developed by Mazda. S-VT varies the timing of the intake valves by using hydraulic pressure to rotate the camshaft. S-VT was introduced in 1998 on the ZL-DE engine and is used in the B-, Z-, MZR- and J-families of engines.
