Mercedes-Benz is making big waves with the brand-new G-Class at the 2018 Detroit Auto Show, but the German firm also launched a new AMG series at the U.S. event. The new AMG line wears the 53 designation and debuts on three cars, one of which is the CLS four-door coupe. Introduced a couple of month back, the third-generation CLS was expected to gain a traditional AMG CLS63 version, but it seems we will have to wait a while longer for that model. Instead, we now get to have a look at the CLS53. As you might have already guessed, the CLS53 will slot between the regular CLS and the upcoming beefed-up CLS63.
