The Audi RS6 Avant Performance and RS7 Performance bring, well, more performance to the table for 2024. Both of these cars use a twin-turbocharged 4.0-liter V8 engine good for 621 horsepower and 625 pound-feet, helping rocket them to 60 miles per hour in just 3.3 seconds. The RS6 is actually the more affordable of the two, asking $126,895 with the destination fee included, while the RS7 costs $127,800. Both of these cars go on sale this fall.
