Hi, I have a 2005 LEXUS IS 300, I was just curious, it seems to run at a higher rpm than I expected...between 60-75, its close to 3000 rpm if not at 3000 , I used to have an acura tl ...65-70 would be at maybe 2500 rpm..is it normal for the IS300 to run at a high rpm...seems like the engine is really working, espiecally for a 5 speed car....Please let me know thanks
