2006 4dr Sedan turbocharged 200hp 2.0L I4
6-speed shiftable automatic AWD		 Overall good fuel economy and quite good range. However, I must add that the fuel pump in the left porition of the fuel tank stopped working on my car, effectively giving me a limited range w/out notice. This caused my car to stall out on three seperate occasions when it ran out of fuel in the right portion of the tank. The fuel tank in this car wraps over the top of the rear diff. The vehicle fuel guage would still read approx. 1/4 tank, yet stall from fuel starvation as the left portion of the tank was not sucking fuel from it; causing a vapor lock. Secondly; fueling this car was time consuming as it had to be filled very slowly, or the pump would shut off. This was shared problem with the evap./emissions system. Lastly, A continual problem with the vehicle's evaporative emissions control system lingers from the manufactorer, and includes known faulty parts. The check pump for the system and its components commonly fail in less than 10k miles. see full Audi A4 / S4 / RS4 review

2006 4dr Wagon 255-horsepower 3.1L V6
6-speed shiftable automatic AWD		 not as good as it should be in my opinion, although in line with the (newer more realistic) EPA figures. see full Audi A4 / S4 / RS4 review
2006 4dr Wagon turbocharged 200hp 2.0L I4
6-speed manual AWD		 Horrible fuel economy in the city. If you are a spirited driver, do not expect decent mileage in the city despite being a 4 cylinder. If you do a lot of highway driving, it may be more acceptable, especially if you don't accelerate too hard. see full Audi A4 / S4 / RS4 review

6-speed manual AWD		 The great engine encourages the use of its power, which affects economy. All wheel drive does not help. see full Audi A4 / S4 / RS4 review
2004 4dr Sedan 340-horsepower 4.2L V8
6-speed manual AWD		 If prices at the pump make your blood pressure rise, or make your wallet whimper...DO NOT BUY THIS CAR! City driving it will go through a tank in about 150 miles combined driving one tank is about 220 miles Highway driving, expect to see 350 to 400 miles from the 17 gallon tank. see full Audi A4 / S4 / RS4 review
2004 2dr Convertible 340-horsepower 4.2L V8
6-speed manual AWD		 If driven aggressively, fuel economy is very poor. And it takes premium. see full Audi A4 / S4 / RS4 review
