I know it a 3.0l V6 pulling a big unit , but ive been REALLY carefull with the right foot. Ive down grading in cost of car and got more space , before the RX i had a 07 plate Audi S3 , and i give it some stick and still returned 22mpg , granted it was only a 2.0l turbo , but remapped to 320 bhp and i wasn't afraid to use it!
