It’s hard to imagine that one of the best looking Maybachs on the road today isn’t actually a Maybach but a custom mega-coupe designed and engineered by the guys at Germany’s Xenatec. Using a donor Maybach 57S as their blank canvas, Xenatec engineers convert the four-door sedan to a coupe using key information direct from Daimler, Maybach's parent company.

The end result is the stunning Maybach 57S Cruiserio Coupe, which has already been delivered to a few select customers in Saudi Arabia and is now making its official world debut at the 2011 Geneva Motor Show this week.

The coupe was designed by Xenatec’s Fredrik Burchhardt, the same man who penned the lines of the original Exelero.

Power comes from the Maybach 57S’ twin-turbocharged 6.0-liter V-12 and is rated at 603 horsepower and 738 pound-feet of torque. This is enough to send the big coupe from 0-62 mph in just 5 seconds and see it reach a top speed of 172 mph. Oh, and in case you were wondering, fuel economy comes in at a dismal 14.3 mpg for the European combined cycle.

A very limited number of the Maybach 57S Cruiserio Coupes will be built by hand in Germany for discerning clients worldwide, and if you’re interested you will have to fork up a princely sum of around $929,685 before taxes.
