MGM Resorts has released a new promotional video which highlights their fleet of specially-designed Cadillac XTS limos which are powered by compressed natural gas (CNG).

Billed as the first-ever Cadillac XTS' to be converted to CNG, the limos are 22 feet long and have a custom interior with premium leather upholstery and "hand-selected" elements to "create the ultimate guest experience."

The company was coy on specifications but the cars have a 3.6-liter V6 engine which has been converted to run on compressed natural gas.  This change enables them to produce approximately one-ninth of the emissions as the previous Lincoln Town Car limousines.
