Seriously naughtiboy I have given mine a few wot runs out on the open road and lethargic is the last word you would use to describe it, it will take you to way above legal in a blink of an eye, in fact throw it into sport mode and you will give a few so called sporty cars a fright, then you can. Look at them and say yep it's a jeep and it's diesel :thumbsup:
