MUNICH – Mercedes-Benz has developed a new V-6 diesel engine that will replace its inline five- and six-cylinder engines starting this spring.
The first application for the new CDI engine in Europe will be the C class. It will be available as a 3.0-liter engine in the C320 CDI.
In the US, the engines first application will likely be the M class.
The E class will keep its inline six for the moment.
With an output of 224hp and a maximum torque of 510Nm, the six-cylinder engine will be one of the most powerful units in its class.
The V-6 diesel is physically more compact than the current inline five- and six-cylinder engines it replaces. It is designed to fit in every Mercedes car except A- and B-class models.
The V-6 diesel offers two primary advantages over the inline engine family it replaces: it fits in the C class (the inline six didnt) and can be used with four-wheel-drive technology. There was no room for a 4wd transfer case with the longer inline diesel.
All Mercedes V-6 diesel engines will have four-valve technology and a variable-geometry turbocharger. The engines feature piezo fuel injectors and common-rail technology. They are coupled to a seven-speed automatic transmission.
In some European countries including Germany, the new engine will have a particulate filter as standard equipment.
Mercedes also will replace its current 4.0-liter V-8 diesel with a same-size new engine based on the new engine architecture.
The companys four-cylinder diesel engines will remain unchanged.
Mercedes-Benz is a pioneer in using diesel engines. The company introduced its first diesel passenger car in 1936.
