About the 2020 Porsche Boxster GTS 4.0

Porsche answered the purists' prayers with the 718 Boxster GTS 4.0, bringing back the beloved naturally aspirated flat-six after years of turbocharged four-cylinders. The 4.0-liter engine, derived from the GT4, delivers 394 horsepower with that intoxicating flat-six wail that made the original Boxster legendary. Beyond the engine swap, the GTS package includes sport suspension, limited-slip differential, and aggressive aero touches that hint at its track-focused DNA. The combination of mid-engine balance, naturally aspirated power delivery, and available six-speed manual makes this the most desirable modern Boxster for driving purists. Early examples are already showing strong collector interest, particularly in manual form, as enthusiasts recognize this as potentially the last naturally aspirated Boxster in an increasingly electrified future.
