Mercedes-Benz M297 engine production ran from 1997 to 2016, establishing itself as one of the most remarkable naturally aspirated V12 powerplants in automotive history.
Derived from the CLK GTR's C297 chassis code, the engine was built upon the foundation of the M120 but received extensive tuning by AMG to meet the rigorous demands of high-performance sports cars.

SubscribeThe powerplant was offered in distinct displacement variants, including a 6.9-liter version exclusively fitted to the road-legal iterations of the CLK GTR, and a 7.3-liter unit that powered various iterations of the Pagani Zonda supercar.
Throughout its production run, engineering refinements allowed the M297 to push performance boundaries, yielding exceptional power outputs that reached up to 559 kW in later series models.
Evolution and Supercar Legacy
Pagani Zonda models relied heavily on the M297 engine, utilizing its most powerful iterations to drive nearly every single version of the supercar manufactured from 2002 onwards.
Technical specifications highlighted its robust construction, featuring an aluminum alloy cylinder block, aluminum silicon cylinder heads, and dual overhead camshafts managing four valves per cylinder.
Power outputs varied significantly across different versions and production years, starting from 386 kW in earlier specifications and scaling up to an astonishing 588.5 kW in the ultra-exclusive Zonda HP Barchetta.
As a successor to earlier Mercedes-Benz configurations and a precursor to subsequent supercar engines, the M297 remains a defining benchmark of V12 engineering excellence.
