The Car Connection's Take

7.5
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. 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.
