CHECK OUT: Ultra-Rare Mosler MT900 GTR Spotted In Monaco: Video

As far as we know, there are no plans to bring back the MT900 but there are still a handful of them around, including one very rare example in Monaco. This video from YouTube user PRonTheRoad shows a Mosler MT900 GTR revving its engine and then racing away through the tunnel running under the Fairmont Hotel.  

The MT900 GTR actually started out life as a MT900 R race car but was made street legal by German importer Mosler Deutschland. That sound you hear is a 7.0-liter LS7 V-8 tuned to deliver a maximum 600 horsepower and 583 pound-feet of torque.
