The extra-long wheelbase Mercedes-Benz S-Class has been spied once again, this time while parked on a street somewhere in Spain.

The new variant will be approximately 200mm longer than the LWB S-Class (5246mm) so it will offer even more legroom for those sitting in the back. It seems Mercedes-Benz will revive the "Maybach" name for this particular model and will keep the 2+2 seating arrangement as in the standard versions.

According to the person who recorded the video, the prototype was an S600 so it was probably equipped with the V12 6.0-liter twin-turbo engine outputting 530 HP (390 kW) and 612 lb-ft (830 Nm) of torque.

Following the possible Maybach revival, Mercedes-Benz will likely introduce an even longer (almost 6 meters) S-Class called "Pullman" which is rumored to have a 2+2+2 seating configuration.

We won't be surprised if the S-Class Maybach will be introduced later this month at Auto China 2014 in Beijing taking into account Chinese customers are huge fans of stretched cars.
