Mercedes GLC 43 – Mercedes-Benz’s AMG performance division’s “43” series so far includes V-6–powered variants of the C-class, the E-class, the SLC roadster, and the GLE-class and GLC-class crossovers.   Purists may decry this broadening of the AMG brand—best known for loud V-8 engines, ostentatious styling, and a general sense of excess—as a simple money grab that leverages a hallowed name against a less-performance-oriented subset of buyers.   But in the case of the GLC crossover, a sprinkling of AMG’s magic dust takes a competent package and makes it more desirable.
