High Quality Content by WIKIPEDIA articles! The Maybach Exelero is a high-performance sports car designed and built by German luxury car manufacturer Maybach. It was presented in May 2005 in Berlin, Germany. The 700 hp (522 kW) two-seater with a twin turbo V12 engine is a one-off design built on request for Fulda Tires. Fulda is using this car as a reference vehicle to test a new generation of wide tires. The German luxury car manufacturer created the one-off model as a modern interpretation of its legendary streamlined sportscar from the 1930s. There are various allusions to the historical predecessor, which was likewise based on a powerful Maybach automobile. In this case, the Maybach SW 38 was also used by Fulda for tire testing.
