700 horsepower and a killer body, the Maybach Exelero may hint a new high-performance model from the ultra-lux sedan maker. The V-12 coupe is based on the Maybach 57 and designed to test a high-speed tire for the German tire manufacturer Fulda. The Exelero needed to surpass the 188 mph mark for Fulda. The super-Bach can get to 55 mph in 4.4 seconds with the help of two turbochargers and 740 ft-lbs of torque. We were amazed how finished the interior was.
