3.0 Manual average RPM at 80MPH?

to those with the 6 spd MT, what is your RPM at 80MPH. I'm hitting 3000 at 80, is this normal or is it a bit high? Thanks

I wish my 5 spd MT did that; I am closer to 3750 at "80", which really isn't even 80...

On the way home, I hit the 80 mark at around 3100-3200 rpm

+1 with my 5 speed. Used to be scared to drive fast because the rpms were so high. Then I got used to it. I think this is why I burn a quart of oil every 1500 miles.

cool..thanks guys.. i guess i'm in the norm.. reason i asked is that i had a ford escape v6 rental and I was hitting 2500-2700 at 80mph with the car being loaded with 4 adults and trunkfull of tools and luggage..

Carrying on...here's my X at 4,000 RPMs: 85 is "indicated" but we all know it
isn't going 85. For comparo, here's my Vette at almost 80 indicated, with
RPMs at ~ 1,700, in 6th gear.

Never understood why a lot of American carmakers gear their top gear so tall.......80mph @ 3000rpm is completely normal for BMWs. As you can see, the older Bimmers with the 5-speed MT rev even higher with the 1:1 ratio.

C'mon Matt: it's because of thousands of miles of 70-80+ mph interstates, quieter running at cruise speed, and the push to return better highway mpg. Would I want to ride around in the Vette with a 4.10 rear end, in 4th gear instead of 6th? I wish our X had an OD or lower numerical axle...4 grand rpms at 80 in the X isn't my idea of engine maintenance.

+1. Took a long distance trip, NYC to Charlotte, NC to Orlando, FL and back to NYC last summer. The engine even begins to get loud at those rpms too. You feel like you're killing the engine.
