The Maybach Exelero is a one-of-a-kind concept car that was developed by Maybach and Mercedes-Benz in 2005. It is based on the Maybach 57 platform, but it features a number of unique design elements, including a stretched wheelbase, a revised front fascia, and a custom interior. The Exelero is powered by a twin-turbocharged V12 engine that produces 700 horsepower and 752 lb-ft of torque. It has a top speed of 218 mph and can accelerate from 0 to 60 mph in 4.4 seconds.
The Exelero was originally commissioned by Fulda Tires as a test bed for their new Carat Exelero tires. However, the car quickly became a sensation on the auto show circuit, and it was eventually sold to a private collector for a reported $8 million. Today, the Exelero is considered to be one of the most valuable and sought-after collector cars in the world.
