When it comes to finding a comfortable ride, it appears you get what you pay for.

In a recent test conducted by Consumer Reports, the organization subjected an assortment of different models to a 30 mile (48.2 km) loop which included a variety of roads in poor condition. The reviewers traveled at a predetermined speed and rated the models on how well they handled the road imperfections.

Unsurprisingly, the Mercedes S-Class came out on top as Consumer Reports said the car’s “plush and steady ride is the best we’ve ever tested.” They went on to say even with the standard suspension, road imperfections seemed to disappear.

The S-Class was followed closely by its key rival, the BMW 7-Series. Unfortunately, the luxury sedan wasn’t quite as polished as reviewers knocked the model’s low speed ride quality which allowed for sharp bumps to be transmitted into the cabin.

Another German sedan came in third and it’s significantly more affordable than the aforementioned flagships. The outgoing Audi A6 was praised for having a comfortable ride which doesn’t feel “overly firm at low speeds” like other models from the four-ringed brand.

Rounding out the models on the list – in order of their rankings by Consumer Reports – is the Lincoln Continental, Audi A8, Genesis G90, BMW 5-Series and Cadillac CT6.

The most affordable model, the Mercedes C-Class, was rated the lowest rated out of the group. However, the organization said the car “delivers a driving experience that is close to ideal when it comes to balancing performance and comfort.” Despite this praise, criticisms were leveled against the car’s run-flat tires for causing some unpleasant impacts when hitting potholes.

While the C-Class starts at $40,250, buyers can still find a comfortable ride on mainstream models that cost significantly less. In particular, Consumer Reports recommends the Chevrolet Impala and Ford Fusion.
