Obey's electric flagship made the cut for GTA 6 Trailer 1. The Omnis e-GT is closely modeled on the Audi e-Tron GT, and game files list AWD, two gears and a top speed of 93.05 mph, all datamined rather than official. It carried plenty of gadgets in GTA Online; how much of that survives into the new game is unknown. Expect instant torque and a quiet, planted drive.
Rockstar has not said how the Omnis e-GT is acquired. Sports EVs sit firmly in purchase territory in this series, so an in-game dealer or website listing is the likely route. Treat that as a guess grounded in past games rather than anything official.
