Nowadays, one doesn’t need a V12 or a V8 to enjoy the AMG experience. That’s because Merc’s performance brand has embraced downsizing, and the AMG 53 range of models is the best example of this practice so fat.

It includes the new-gen CLS, among others, which is, and will remain, the range-topping version of the four-door coupe, as the full-blown 63 (in normal and S guise) has been reserved for the GT 4-Door Coupe.

This, though, doesn’t mean that those who opt for the CLS 53 will feel short-changed; quite the opposite, actually, as it is faster than not-so-old supercars. And it’s quite friendly to the environment, too, as it uses a 3.0-liter turbocharged inline-six with an EQ Boost starter-alternator that powers the car’s high-tech 48V electrical system.

The CLS 53 is, thus, a mild-hybrid, and a quite a punchy one at that, with a total output of 429 HP (435 PS / 320 kW) and 520 Nm (384 lb-ft) of torque. The powertrain is mated to a 9-speed automatic transmission and all-wheel drive, and performance, for something that can carry four and their luggage in comfort, is great.

Naught to 100 km/h (0-62 mph) takes only 4.5 seconds, according to Mercedes-AMG, and top speed is electronically limited to 250 km/h (155 mph), or 270 km/h (168 mph) if you opt for the AMG Driver’s Package.

So far, everything sounds very promising, but what about in the real world? AutoTopNL took the CLS 53 out for a short drive, checking out its performance on back country roads as well as in a straight line. Suffice to say that the Merc does not disappoint (quite the opposite…), so you might want to free your schedule for the next 11+ plus minutes and check it out below.
