Continuously variable valve timing on both sides. I actually researched this one already: Nissan states a 4% improvement in efficiency with this setup in combination with twin fuel injectors per cylinder. They even say they use an Atkinson mode at idle to reduce pumping losses.

Continuously variable valve timing (CVTC) on Micra 1.6L HR16DE - Micra-Forum.com

Is the cruse control aggressive or lax?
Will try this too, and ask about the throttle setup.

Thanks for the questions, guys.
