I run the revs up way more on my MCS before shifting than another other vehicle I have ever owned, and I am not affraid to run it at 3-4K while cruising. I have found the sweet spot for power and economy to be in that 3000-3500 range. On the other hand, the big V8 in my Nissan Titan is like a Budweiser clydesdale, tons of power and torque, but the revs rarely get above 2-3K even under hard acceleration and the sweet spot on that motor is 1500-2000 rpm. Our Mazda CX9 falls somewhere between the two. The Porsche 912 likes to rev too, but not anywhere near the MCS. The older pushrod engines just don't spin like the MCS with it's overhead cams, direct fuel injection and variable valve timing, etc. The point being don't be afraid of breaking it. I was at first, but I got over it quickly.
