The M297 is a V12 engine produced by Mercedes-Benz, from 1997 to 2016. Engine code was derived from the CLK GTR's C297 chassis code.[1]

Design

[edit]

The M297 is based on the M120 engine but has been tuned by AMG for use in high-performance sports cars. It was offered as a 6.9 L (6,898 cc) version with a bore and stroke of 89 mm × 92.4 mm (3.50 in × 3.64 in), respectively, and was only available in the road-legal version of the CLK GTR.[2] A 7.3 L (7,291 cc) unit was also available featuring a larger bore of 91.5 mm (3.60 in), and was used in Pagani Zonda models until 2016.[3]
