“Incredibly fun! Precise handling, amazing performance, great sound system. Heated seats make it possible to drive this even in cooler temps. More cargo area than you'd expect with both a trunk and frunk. Surprisingly practical for singles or couples without kids. Low road noise for a convertible top up or down.”
2018 Porsche 718 Boxster: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for the 2018 Porsche 718 Boxster is the arrival of the GTS, a new 365-hp model with major performance hardware fitted as standard. The base Boxster and Boxster S carry over without major changes.
About the 2018 Porsche 718 Boxster
4th Boxster generation / 718 era (982), second year after the 2017 redesign; first year for the GTS.
Porsche positions the 718 Boxster as a true mid-engine two-seat roadster built around balance, quick responses, and open-top driving rather than cushy cruising. Its core appeal is precise handling, strong turbo power, and a driver-focused cockpit in a compact convertible shape. Against rivals, the Boxster’s biggest draw is how connected and confidence-inspiring it feels on a winding road while still being usable day to day.
The 2018 lineup starts with the 300-hp base roadster, while the 350-hp S adds a stronger 2.5-liter engine and 19-inch wheels. The new 365-hp GTS is the most performance-focused version, with lowered adaptive suspension, torque vectoring, a sport exhaust, 20-inch wheels, and a more focused interior.
