[QUOTE="soberups, post: 1505539, member: 14668"] A spoiler is used on a racecar where ultra high speed traction is critical and fuel economy is not an issue. It creates downward force on the back of the car at the cost of increased drag, which is an acceptable compromise due to the fact that racecars have far more power than can be transmitted to the rear wheels without slippage. A wing on a car that could create enough lift to increase fuel economy by decreasing rolling resistance would have that decrease offset by the resulting increase in drag and weight. Your idea is intriguing but unfortunately you cant get something for nothing. [/QUOTE]
