An unnamed full-size saloon is due to appear in Grand Theft Auto VI, so far known only from an interior view in an official screenshot showing Raul Bautista driving with a duffel bag of money on the passenger seat. Its swooping center console, dashboard, gauge hood and door cards most closely resemble the Mercedes-Benz W211, and it carries what looks like a functional infotainment display identical to the Dominator GT's.
