Just curious, I punched the pedal to the floor getting on I-5 today with our toddler son (who took a nasty hit to the head on concrete at the playground-kid is fine now). We were on our way to the E.R. I saw the engine reach a Quad-4 like 6500 RPM before shifting. Oh, and my son giggled and said "go momma's car!" P.S. Love the sounds the big 6 makes at high power.
