It's your call
The new Dynamic Handling Package – available as an optional extra for the new
C-Class Sport* – lets you adjust the car’s driving characteristics to suit your mood.
Choose 'Comfort' Mode and you’ll enjoy a smooth, luxurious ride. The continuously variable dampers adjust to suit the road surface and driving style, reducing road noise and vibrations. Meanwhile, the car’s control module ensures that gearshifts are seamless and throttle and steering response is subtle and understated. In Comfort Mode, cruising is the order of the day.
But if you’d prefer something a little more exhilarating, simply push the button to 'Sport' Mode and everything changes.
With the continuously variable damping, handling becomes more taut, body roll is reduced and the ride becomes firmer. Steering and throttle response becomes sharper and gear changes more responsive (automatic transmission only). Even ESP® (Electronic Stability Program) intervention is marginally reduced to help enhance the dynamic driving sensation – without compromising active safety, of course.
