While Cadillac is moving out of the livery segment—it doesn't jive with new chief Johan de Nysschen's vision for the brand—we'll be seeing XTS-based limos on the road for years to come. With that in mind, MGM Resorts International has adopted the world's first fleet of CNG-fueled stretch limousines, which produce 1/9 the emissions of similar gas-powered vehicles, and have a 200-mile range.

While the cabins of these Cadillacs aren't as lavish as the recently revealed Mercedes-Maybach Pullman limo—in fairness, virtually nothing is—the 31-car fleet will feature appropriately luxurious interiors, and since each is a full 70 inches longer than traditional limos, should be able to convey even the largest bachelor parties or groups of inebriated convention goers with room to spare.
