The New V6 Engine From Mercedes Benz

The New Mercedes Benz V6 Engine

Mercedes Benz SLK-Class

Series start-up in spring 2004 in the future SLK-Class

For the future SLK-Class Mercedes Benz has developed a new six-cylinder engine whose exemplary output and torque characteristics are supremely well-suited to this sporty, dynamic sports car and guarantee driving enjoyment at the highest level. In addition this state-of-the-art 3.5-litre power unit sets new standards in fuel consumption and noise comfort with a number of technical innovations.

With an output of 200 kW/272 hp and 350 Nm of torque, the new Mercedes six-cylinder unit is one of the most powerful V6 engines in its displacement class. The maximum torque is already available from 2500 rpm and remains constant over a wide engine speed range up to 5000 rpm, providing powerful acceleration and rapid sprints.

The aluminium engine excels with a unique package of technical features. For the first time in a V6 engine it has variable intake and exhaust camshaft adjustment, which increases the output and torque while contributing to fuel economy. A two-stage intake manifold, tumble flaps in the intake ducts and an intelligent heat management system are further technical highlights in this new six-cylinder engine for the future SLK-Class.

The variable, continuous camshaft adjustment system controls the 24 valves in the aluminium cylinder heads. It helps to ensure that the valves open and close at the most favourable time in any driving situation, significantly improving the charge cycle in the cylinders and reducing energy losses. As a result this technology reduces fuel consumption under partial load, while ensuring an optimal supply of fresh gas to the combustion chambers under full load. The new Mercedes six-cylinder is the world's first V6 engine with variably adjustable intake and exhaust camshafts.
