More power for the new CLS

Mercedes-Benz CLS 350 d

The CLS brings a new design language to the model range of Mercedes-Benz. The overhang at the front grows so that the nose hangs even lower over the asphalt. Also in the rear, the overhang also grows flush to complete without a step to the bumper. The CLA looks more elegant and sportier-aggressive than ever before. In the interior, the CLS is reminiscent of the E-Class, leather and wood wherever the eye can see. The 3-liter straight-six in the CLS 350d makes 286 series horsepower, here comes the engine-specific chip tuning of the CPA PowerBox into play. Up to 63 HP and 131 NM extra power are playfully possible and will benefit the R6 in every way. Thanks to the standard four-wheel drive, the power is transferred unimpeded to the asphalt while the 3-liter diesel infatuates with its fine, silky barrel. If you want to get even more out of your CLS, you are well served by the CPA Connective System. It offers the driver the opportunity to change the driving modes at any time, the extra power is regulated as needed and in combination with the PedalBox, the system reaches its full potential.
