The GT was introduced in 2018 as a variant of the Polaris Slingshot. It maintains the distinctive three-wheel roadster-style body equipped with rear-wheel drive. Until 2019, it used the 2.4L inline four engine, but from 2020 it uses the ProStar 2.0L engine. The transmission can be manual or automatic, depending on the configuration. The GT is distinguished by incorporating features geared towards comfort on long trips such as a tall windshield, more comfortable Touring seats and Ride Command touchscreen with navigation.
