Design

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]

The Mercedes-Benz M120 engine is a naturally aspirated high-performance automobile piston V12 engine family used in the 1990s and 2000s in Mercedes' flagship models. The engine was a response to BMW's M70 V12 engine, introduced in 1987.

It is loosely based on the M137 naturally aspirated V12 sold between 1998 and 2002, and retains its SOHC, 3 valves per cylinder, twin-spark ignition layout, but differs with the addition of structural reinforcements to the engine block for improved rigidity which in turn yields greater reliability. The M275 V12 Bi-Turbo engine was modified with the addition of larger turbochargers. Several variations of the M275 V12 Bi-turbo engine have powered many top-of-the-range Mercedes-Benz and Maybach models since 2003.

<span class="mw-page-title-main">Mercedes-Benz M137 engine</span> Reciprocating internal combustion engine

The Mercedes-Benz M137 engine is a naturally aspirated, SOHC 60° V12 engine, with three valves per cylinder, 2 intake and 1 exhaust. It was built to replace the larger and heavier, yet more powerful, DOHC, four valves per cylinder, naturally aspirated, 6.0 L M120 V12 unit. The M137 was used briefly between 1998 and 2002 for the V220 S-Class and C215 CL-Class. The architecture is similar to M112 and M113 engines, and is designed to match the overall dimensions of a V8 unit with undersquare internal measurements. The crankcase was cast in a lightweight alloy with "Silitec" (silicon/aluminium) cylinder liners to save weight. The M137 is 80 kg lighter than its predecessor and features cylinder deactivation technology. Both displacement variants have 10:1 compression ratio.

<span class="mw-page-title-main">Mercedes-Benz CLK LM</span> Sports car built by Mercedes-AMG

The Mercedes-Benz CLK LM was a Group GT1 sports car designed and built by Mercedes-Benz in partnership with AMG to compete in the FIA GT Championship. To satisfy the requirements of competing in the FIA GT Championship, a road-legal version had to be built to homologate the car. That car was known as the Mercedes-Benz CLK LM Straßenversion, and Mercedes-Benz assembled two chassis, one of which was destroyed for crash-testing. The CLK LM went on to win every single championship event in the 1998 FIA GT season, retiring only at the 1998 24 Hours of Le Mans, which was a non-championship event. The removal of the GT1 class from the FIA GT Championship due to the lack of entrants and rising costs meant that Mercedes' GT1 program was brought to a close at the end of 1998. Mercedes instead focussed their efforts on the newly introduced LMGTP class for the 1999 season, which produced the Mercedes-Benz CLR.
