Engine Variants
M276 DE35 (Naturally Aspirated 3.5L)
The Mercedes-Benz M276 DE35 is the naturally aspirated 3.5-liter version of the Mercedes-Benz M276 engine family, produced from 2010 to 2017. It delivers approximately 248–302 horsepower and was designed to provide smooth power delivery and improved fuel efficiency compared to its predecessor engines. This variant was commonly used in several mid-range Mercedes models, including the Mercedes-Benz E350 (W212), Mercedes-Benz C350 (W204), and Mercedes-Benz GLK350, offering a balance of reliability, refinement, and everyday performance.
M276 DE30 LA (Twin-Turbo 3.0L)
The Mercedes-Benz M276 DE30 LA is a 3.0-liter twin-turbocharged version introduced around 2013–2014 to replace the larger naturally aspirated 3.5-liter engine. Despite its smaller displacement, it produces about 328–367 horsepower while delivering significantly higher torque and improved efficiency through turbocharging. This engine powered models such as the Mercedes-Benz E400, Mercedes-Benz C400, Mercedes-Benz GLE400, and Mercedes-Benz S400, reflecting Mercedes-Benz’s shift toward downsized turbocharged engines.
M276 AMG / High Output (Twin-Turbo 3.0L)
The high-performance version of the Mercedes-Benz M276 is used in several Mercedes-AMG performance models. This upgraded twin-turbo 3.0-liter variant produces roughly 362–429 horsepower, featuring enhanced turbochargers, tuning, and cooling systems for higher output. It powers AMG “43” models such as the Mercedes-AMG C43, Mercedes-AMG GLC43, and Mercedes-AMG GLE43, as well as some “400” and “450” variants, delivering a strong blend of luxury and sporty performance.
