Polaris introduced this nameplate for the 2018 model year as the four-seat expansion of its Turbo S performance side-by-side line. The launch followed the original two-seat Turbo S and positioned the new version as a wider, family-sized machine aimed at riders who wanted the same aggressive desert-focused character with added seating. Polaris’ own launch materials described it as the four-seat version of the Turbo S platform and emphasized its place in the RZR performance family. In Polaris’ 2018 RZR lineup, the model appears under the XP Turbo S naming, and the company continued to offer it through the 2019 and 2020 model years. By 2021, Polaris’ public lineup and product materials had moved to the Turbo S 4 naming, indicating the end of the XP 4 Turbo S nameplate rather than a separate revival. The model is therefore best understood as a short-lived, first-generation four-seat Turbo S variant within the broader RZR performance era. It is notable among enthusiasts as the introduction of a high-performance four-seat RZR with Polaris’ DYNAMIX Active Suspension, helping define the brand’s premium sport side-by-side strategy before later Turbo S 4 and Pro XP 4 models took over that role.
