New, Powerful V6 Engine For The Future SLK-Class

The New Mercedes Benz SLK-Class Roadster

Mercedes Benz SLK-Class

Six cylinders for sporty roadster enjoyment
  • Superlative output, torque and fuel economy
  • Fourfold camshaft adjustment for powerful performance
  • Two-stage intake manifold with tumble flaps on the intake ducts
  • Outstanding noise and vibration comfort

A new model – a new engine: this combination is a rare occurrence in automobile development. Mercedes Benz will be offering it in the coming SLK-Class from spring 2004.

The newly developed sports car will enter the fray with an equally new engine which meets drivers’ expectations of a powerful and lively roadster in all respects. No other V6 engine in this displacement class is able to offer output and torque characteristics which have been so specifically designed for dynamic performance and enjoyment as this new development by Mercedes Benz, which also makes its mark in terms of fuel consumption, exhaust emissions and comfort.

Output: the new 3498 cc six-cylinder engine develops 200 kW/272hp at 6000 rpm, corresponding to an output per litre of 57 kW/78 hp – an outstanding figure in this displacement class.

The same applies to the torque: 350 Nm are already on tap from 2500 rpm and remain constant up to 5000 rpm. This guarantees fast acceleration and rapid sprints, but also relaxed driving in the lower gears – catering for the wishes of roadster fans who enjoy the occasional extended tour with the vario-roof open.

And finally fuel consumption: 240 g/kWh is the value quoted by the engineers as the actual, specific fuel consumption at the best engine operating point. In practice this translates into an NEDC overall fuel consumption of less than 10 litres per 100 kilometres, an exemplary figure for this performance class.

A team of around 500 engineers, technicians, mechanics, production planners and partners from the supply industry was involved in the development of the six-cylinder engine, and approx. 400 test engines have proved their worth on test benches and during practical trials in all the climatic zones of the world since the start of the project.

From spring 2004 Mercedes customers purchasing the SLK-Class will be able to experience the qualities of the new V6 engine for themselves.
