Motor Mercedes-Benz OM642 V6

O V6 diesel de 3,0 litros que substituiu uma geração de CDI de cinco e seis cilindros em linha — mais curto, mais suave, espinha dorsal do BlueTEC.

A produção em série começou na primavera de 2005 após cerca de quarenta meses de desenvolvimento. Um bloco de alumínio a 72° com camisas fundidas, cabeças DOHC de quatro válvulas, veio de equilíbrio entre bancadas e contrapedais de virabrequim deslocados para intervalos de ignição regulares de 120° reuniram common rail de terceira geração (injectores piezo até 1.600 bar) e um turbo Garrett de bicos variáveis num pacote curto o suficiente para a Classe C. A taxa de compressão desceu por etapas de 18:1 nos primeiros motores para 15,5:1 nas versões LS e SCR posteriores; as primeiras potências de automóvel concentravam-se em torno de 165–190 kW com mais de 500 N·m desde baixas rotações — e foi o primeiro diesel Mercedes oferecido com 7G-Tronic.

Do C 320 CDI e E 320 CDI aos ML, GL, Classe R, carrinhas e posteriores aplicações BlueTEC SCR, o OM642 abrangeu automóveis de passageiros, SUV e chassis comerciais até aos anos 2020. Também moveu os primos Chrysler, Jeep e Freightliner antes de o OM656 seis em linha modular assumir o papel de flagship diesel de Stuttgart.
