I've noticed that when I'm on the interstate going about 55-65 mph, the RPM's stay at least at 2K-2.5K. Is this normal with these cars, or does that sound like a transmission issue?

Thank You!

At 65mph in your SDL I would expect rpms around 2500-2600 or so...these are not as low-revving cars as your typical american car.

I also for some reason cannot get the RPM's to go over 2800-3K at speeds of 25-45 mph. I will get some 0-60 times tommorow.

Thanks for ANY and ALL help!
