The Penumbra is a two-door sports coupe from Maibatsu that previously featured in GTA V and GTA Online and is due to appear in Grand Theft Auto VI. A silver example was spotted parked at a Crosstown intersection in the first trailer, and the car also surfaced briefly in the September 2022 GTA VI leaks.
