TCC’s Bottom Line
The 2018 Audi A5 gets a hatchback body style that adds a measure of utility to go with its sleek and sporty luxury cachet. The 2018 BMW M4 lives up to its heritage as an entertaining performance car, both on the track and your favorite twisty road. Very expensive and still not very large, the 2018 Mercedes-Benz C-Class nonetheless leads its luxury niche with fabulous style and fantastic power and grip.
