MERCEDES-BENZ The SLK R171

MERCEDES-BENZ SLK R171 Revised and Expanded 2026 Edition Complete Model History, Engineering and a Detailed 40-Page Buyer’s Guide A well-maintained Mercedes-Benz SLK R171 can combine open-air enjoyment, everyday usability and serious performance in a remarkably compact package. A neglected example, however, may conceal mechanical, electrical or roof-related problems that can lead to substantial repair costs. This revised and expanded edition combines the complete history and technical development of the R171 with a detailed 40-page buyer’s guide. Introduced in 2004, the second-generation SLK brought a more dynamic and sophisticated character to the compact roadster. Its styling reflected influences from Formula One and the Mercedes-Benz SLR McLaren, while its retractable Vario-Roof combined open-air driving with the security and practicality of a fixed-roof coupé. The model range extended from the supercharged four-cylinder SLK200 Kompressor through the SLK280, later renamed SLK300, and SLK350 to the V8-powered SLK55 AMG. The exceptionally rare SLK55 AMG Black Series represented the most uncompromising development of the R171. The extensive 2008 model update introduced numerous technical and stylistic improvements. The book covers: • COMPLETE MODEL HISTORY The development of the R171 from its introduction in 2004 through the major 2008 model update and the final production years, including European and North American versions. • ENGINES AND ENGINEERING The M271 four-cylinder, M272 V6 and M113 V8 engines, supercharger systems, manual and automatic transmissions, suspension, steering, braking systems and the principal technical developments introduced during production. • SLK55 AMG AND BLACK SERIES The naturally aspirated V8-powered SLK55 AMG and the rare SLK55 AMG Black Series with its fixed carbon-fiber roof, reduced weight and more focused specification. • VARIO-ROOF AND ELECTRONICS Roof operation, hydraulic pump, cylinders, switches, seals, water ingress, electronic systems, convenience functions and other components that may affect reliability. • SPECIAL EDITIONS AND TUNERS Edition 10, Grand Edition and other special versions, together with interpretations by Brabus, Piecha, RENNtech and additional specialists. • REFERENCE AND ORIGINALITY INFORMATION VIN decoding, data cards, production information, technical specifications, factory equipment and important identifying features of the different R171 models. • DETAILED 40-PAGE BUYER’S GUIDE Bodywork, corrosion and previous repairs, engines, oil leaks, balance-shaft sprocket concerns, transmission identification and condition, suspension, brakes, electronics, SmartKey functions, roof hydraulics, interior equipment, service history and other areas where age or neglected maintenance can become costly. Unlike a conventional buyer’s guide, this book also presents the complete history and technical development of the R171. Unlike a general model history, it provides practical guidance for inspecting, purchasing and owning these distinctive compact roadsters. Whether you are considering purchasing an R171, already own one, or simply appreciate the second-generation SLK, this carefully researched and richly illustrated book offers a comprehensive guide to its history, engineering and many variations.
