The R172 SLK 55 AMG (2012-2016) is the third-generation SLK in its hot form, powered by the naturally aspirated 5.5L M152 V8 with around 421 hp, paired to a 7G-Tronic Plus automatic. Its retractable hardtop and compact roadster layout give it a distinctive character, and it is among the last small AMG V8s before turbocharged downsizing. It is regarded as a rare, characterful end-of-era roadster.
A naturally aspirated AMG V8 in a compact two-seat roadster is a combination that has effectively disappeared from the market, and the M152 delivers a rich soundtrack and linear power. Its relatively low production numbers and the fact that it was the final SLK to carry the V8 make it increasingly significant to enthusiasts.
