A full-size Declasse sedan is due to appear in Grand Theft Auto VI; footage from the September 2022 leaks clearly shows Declasse badging on the grille, C-pillar and rear. Two examples were also spotted in traffic near the intersection held up by doughnut-spinning cars in the first trailer, and based on analysis the design draws on the ninth-generation Chevrolet Malibu among other influences.
