In a CVT when you give it gas the engine will basically pick a certain RPM and it will stay there until you change the throttle position. In my Altima I tested for acceleration consumption, but I stopped measuring at the same point on the road. Faster acceleration got me to speed quicker which allowed just about the same average MPG to the same spot in the road. Of course more rapid acceleration got me to speed faster, while slower acceleration took longer. Bottom line was the MPG was just about the same regardless of the throttle position until you really accelerated quickly which cost MPG, measured to the same point.
Our 2006 Murano would accelerate to 70 MPH without the RPM changing at 1700, with a constant throttle position.
