As a seasoned player who has driven old Mercedes for over a decade, the engine differences across CLK generations are quite significant. The first-gen W208 initially featured the 2.0L four-cylinder M111 and 2.4L V6 M112, later upgraded to the supercharged 1.8L M271. The second-gen W209 stepped up its game - base models used the M272 series 2.5L/3.0L V6, while the high-end CLK500 packed the 5.0L V8 M113. The top-tier CLK63 AMG directly stuffed in the 6.2L V8 M156 engine, whose exhaust note could literally give you goosebumps. The tuning community particularly favors the CLK55 AMG, as its supercharged M113 engine has enormous potential.

Decades of experience working on dozens of CLKs in repair shops reveals: The first-generation CLK most commonly features the cast-iron block M111 four-cylinder engine—durable but noisy. After the 2003 facelift, the W209 generation came standard with all-aluminum engines, primarily the M272 V6 available in two versions: a 184-hp 2.5L and a 231-hp 3.0L. Crucial reminder for used car buyers: Pre-2006 M272 engines have a known balance shaft gear design flaw—always check maintenance records during inspection. The diesel-powered CLK270 CDI's OM647 inline-five turbo diesel is exceptionally robust, often exceeding 300,000 km without major overhauls.

Back when I was trained at the 4S dealership, I memorized the CLK engine code list: The entry-level CLK200 Kompressor used the M271 supercharged engine with 165 horsepower, which was sufficient but prone to bursting water pipes. The CLK350 came standard with the M272 V6 producing 272 horsepower. The performance versions had three tiers—the CLK500's M113 V8 delivered 306 horsepower, the CLK55 AMG's 5.4L supercharged V8 squeezed out 367 horsepower, and the ultimate CLK63 AMG's 6.2L V8 pushed straight to 481 horsepower. What tuning enthusiasts were most obsessed with was the limited-edition CLK DTM launched in 2003, whose supercharged V8 could crank out a whopping 582 horsepower!
