I just traded in my 6th gen accord v6. and got the xB. At 90 mph my accord was like a quiet like a tomb. At 70 in the xB 5th gear is around 3.5k RPM, (kinda loud). I know you can't compair the 2 aples to apples. Is it healthy,? I mean what does it do to your milage to cruise for long periods between 3-4k RPM?

(you gotta love the little growl of the DOHC when it's tryin' hard though)

:lol: Your milage will suffer some, also where in America is the speed limit 90mph?

Try driving the freeway in north suburbs of Chicago. it's posted 55, people regularly doing 100-110. Serious

:shock:. I know its not safe to do the speed limit in those cases. The main thing though, compare driving at 55 instead of 90 your gas milage would be greater.

Gas mileage decreases rapidly at speeds above 60 mph. Each 5 mph you drive over 60 mph is like paying an additional $0.10 per gallon for gas. Observing the speed limit is also safer.

I agree, the engine is loud. I was talking to my Dad (who is an asst. service mngr for Toyota) and asked him if he knew of a way to quiet it. Nothing yet, but he is working on some ideas. My 4-Runner was really quiet and it was a V6. But, I love the style 8) of the xB and the gas mileage so it is worth it!!!

I don't find the noise obtrusive at 60-70 mph. I get over 35mpg at those speeds.

well @ 80MPH my MT xB is at 4000 RPM- And no it didnt hurt my mileage because I still got 42MPG( I did a 430 mile trip- took only 10.3 gallons)!!!

Thanks VVT-I!!!

It feels like the natural speed the box wants to go is about 55 or 60. Ask it to go faster and your hearing about it. I felt like the natural speed on my Accord was about 75-80. Guess I'll just have to get used to the fact that the box ain't a luxury vehicle.

I drive 80 MPH almost everyday here in the Detroit area. I do a 10 mile strech on the freeway. The xB is fine at this speed and I have lots of pedal left for power when I need it. I think this is the main thing, not the RPM but the amount of work the engine has to do. Lower RPM at highway speed requires more power for acceleration etc. That is why V6's and V8"s are lower RPM. But on the other hand higher RPM can use more fuel. So it is a balance of havung enouigh power vs RPM. The power band of small engines also is at higher RPM.

4000 RPM sounds high at 80 MPH but there are mony other cars at that RPM or more out there. At first I alos thought was as issue but I not concerned at all now. I love the xB with a stick shift.

i drove to Temecula from long beach whicn is over 100 miles with a 3 passengers, 80 miles and hour all the way there and back in my 2005 xb with manual trans. yes a little loud, but the box ran like a champ. seems she likes to be let out and ran!

you want noise, try my 4x4 Tacoma. between the 32 muds [lots a noise and the more wear the more noise] and borla muffler I have my radio cranked to the max to cover the singing of the tires.

so comparing my xB to my truck it is MUCH quieter :lol: it all depends on what you are used to.
