I figured out the chords in this one. Pretty cool chords for a pretty cool song. 
Much more accurate then the other version, this one sounds right.

Tuning is standard, with no capo.

 used are as follows:

Am: x 0 2 2 1 0
Am6: x 0 4 2 1 0  (note: before going to C, drop the 2 to 0)
C: x 3 2 0 1 0
Csus4: x 3 3 0 1 0
D6add4add9: x 5 4 0 0 0
Dmadd9: 10 12 12 10 10 0
C#m#5addb9: 9 12 12 9 10 0
Cbar: 8 10 10 9 8 0
Gm6: 3 5 5 3 3 0
Em7b5: 0 5 5 3 3 0
A: x 0 3 3 3 0
Am7: x 0 10 9 8 0
Dadd9: 10 12 12 11 10 0
FM7: 1 3 3 2 1 0
G13sus4: 3 3 3 x 1 0
D: x x 0 2 3 2

Alright now on with the song!


Am
I wanna be bigger, stronger
                   Am6
Drive a faster car

To take me anywhere in seconds
C             D6add4add9    Am
To take me anywhere I wanna go
