There is something very Goldilocks about an Audi S4. The compact sport sedan is just the right size; the turbocharged V-6 is powerful and lusty enough to offer a thrill while still serving as a comfortable daily driver, and the Audi-caliber interior is just premium enough without dipping into a luxury coma that might threaten to lull the senses.
For the 2020 model year, the S4 gets a significant refresh—enough change to warrant a trip to Palm Springs, California, and a drive through the desert to see how the new S4 stands up.
