what is the difference between a 6 speed automatic and an automatic
The EX and SX models comes with a Standard 6 speed automatic transmission and the LX and Koup come standard with a 6 speed Manual trans. Not sure what you are asking.
Short answer: 6 speed Automatic provides better fuel economy & performance compared to 4 or 5 speed Automatics.
