McLaren is reportedly ending production of gas-only supercars with the introduction of a new model. The company's final gas-only supercar may be the 750S, although some outlets suggest it could be the 788HS, which is described as a limited-edition evolution of the 720S series. The end of gas-only supercar production may signal a shift in the company's focus, with some speculation about potential future models, including exotic super-SUVs and electric vehicles.
