The 2014 S-Class, without a shade of doubt, is the best luxury limousine at this point in time. When we reviewed the S500 variant of the car a couple of months ago, the quality of materials, the technology inside, the tranquil cabin and the stupendous dynamic ability of the machine simply blew us away. The new S-Class has created an extremely difficult benchmark for the rest of the luxury carmakers to achieve. The only downsides of the fully-imported S500 petrol car were its steep price and not-so-enticing fuel efficiency, even for the super rich. To address the issue, Mercedes-Benz India has now introduced a locally assembled version of the limo with a much preferred diesel power plant under the bonnet.
