GT down to 4 - cl!?!? - are you feeling o.k. !! no offence - but here's the rationale - v6 in same car compared to v8: the 6 has to work harder to haul around the car than the 8....the gas economy is no better!! done the testing...the 6 will wear faster... also, driving an 8 without being on it all the time gaives same economy as the 6 3.8L....sorry, i'm just another muscle head!!!
