A picture of the new Mercedes-Benz S-class has been leaked, revealing the new 'W222' model in full.

Mercedes-Benz had previously been unveiling the new car from the inside out, releasing detailed interior shots. A series of spy shots, however, did show the undisguised exterior of the S-class.

The manufacturer has focused heavily on improving interior comfort in the new model, due to the growing importance of luxury saloons in the Chinese market and the failure of the Maybach brand.

Daimler chief Dieter Zetsche said "Pushing the S-class upmarket will also further strengthen and balance the Mercedes brand at the top end, just as we are going smaller with the A-class range of cars."

The image, which appears to be an official shot of the car, appeared on the web ahead of the car's premiere on 15 May.
