Just out of curiousity.
So the other day i was driving in my moms minivan with the family on the highway, cruising at 80 mph w/ the RPM's @2500. She owns a 2003 Chrysler town & country limited edition. Now today i was driving my badass G35 6MT 03 coupe and i was cruising at 80 mph w/ my RPM's @3000. What does this mean that the minivan has a more efficient engine? I was just curious so if anybody knows about this lemme know Thx!

The van can afford to drop into a really wide gear to save gas, hardly anyone would ever track or drag it. Where as the G is meant to get up to 155mph, if it had a wider 6th gear you'd never reach 155mph or it would take forever and a day to get there. So in short the van is geared for fuel economy, and the G is geared for performance.

And yea i was surprised too when i noticed my G going @3000RPM>80mph and the van at 2500 rpm. But oh well i guess its not a big deal....

I'm not sure if it applies to the GTO's but alot of the large displacement motors are now going with active fuel management or the action of shutting down half of the cylinders when it's not required such as at highway speeds or low power requirements to save gas.
Generally what I've noticed is the lower the number of cylinders the higher the RPM to maintain a given speed. 2 of my previous cars a 90 corvette and 94 Trans AM would do around 1500 RPM in 4th gear at 55, where my last car '01 Grand Prix GTP would do 55 at 2000 RPM. All 3 had the same HP rating of 240-245.
