Doug DeMuro gives the 2026 Mercedes-Benz CLK63 AMG Black Series a mixed review (57/100), praising it as an exhilarating performance machine with a naturally aspirated 6.2L V8 producing 500 horsepower, 0-60 in 4 seconds, and distinctive DTM-inspired widebody styling with carbon fiber upgrades. The car excels in its exclusivity—only 500 built worldwide—and delivers what DeMuro calls "an absolute hoot" to drive, though practical livability suffers due to deleted rear seats that ironically didn't achieve meaningful weight savings, and the steering demands constant attention. Quirky cabin design choices like the oversized glove box latch and six-disc CD changer occupying most storage space further detract from everyday usability. This is a car for enthusiasts who prioritize raw thrills and collector appeal over comfort and convenience.
