Screaming fast. Fantastic fun

Mark J, 01/19/2019
2018 Audi S5 Premium Plus quattro 2dr Coupe AWD (3.0L 6cyl Turbo 8A)
5th update: 54,000 miles and 7.5 years. Still love this car. 4th update: 49,000 miles and almost 7 years. Still love this car. 3rd update: Not change, but needing breaks at 38,000 seems too soon when about 70% of the miles are highway miles. 2nd update: Just turned 36k miles and still love the car. Just replaced tires. I learned that Audi uses a bit of negative camber (helps … with cornering) which causes the tires to wear on the inside at a faster rate than normal. Hence, be sure to get the treadwear guarantee and rotate tires to get a healthy credit toward the new tires. Update: After 4+ years of ownership I still love this car. Everything below is still valid. Total mileage after 4.75 years of ownership is about 32,000 I've put 12k miles on the car and have not had any troubles. The dealer support for a condenser that was perforated by a rock was above and beyond. The car is blazing fast. Way better than my G35 or 530 ever were. The S5 is also more refined than those cars too. Since I drive 80 - 85 on the highway, when I need to pass and punch the gas it jumps to 100 almost instantly. Acceleration to 60 is also terrific. Road holding (I have the optional split differential) is incredible. A corner that I could never get past 37 in the G35 I've already done effortlessly at 55 in the S5. I'd try it faster, but there is not enough road to get the speed any higher. I've taken the car on an 850 mile one day drive and found it to be extremely comfortable (I'm 6'0 and 200 pounds). Fuel economy on that road trip was 30 MPG. Around town which is a mix of city/highway mpg is 22. This is based on using premium grade fuel. In regards to the turbo lag, I have found it to be almost imperceptible when the transmission is in sport mode. I basically keep it in sport until I reach a road where I can cruise at a steady speed. Oh, and the car gets plenty of looks. Its a work of art.
