About the 2020 Porsche Cayman GTS 4.0

The GTS 4.0 answered enthusiast prayers by returning the naturally aspirated flat-six to the Cayman lineup. The 4.0-liter engine, shared with the 911 GT3, produces 394 hp while delivering the intoxicating soundtrack that turbocharged engines cannot match. This represents the sweet spot in the 718 range, more accessible than GT4 models but retaining the emotional connection of natural aspiration. The six-speed manual transmission option preserves the pure driving experience that defines great Porsches. Starting at $90,600, the GTS 4.0 offered significant value compared to GT models while delivering 90% of the performance. Collectors recognize this as potentially the last naturally aspirated 'regular' Cayman, making it increasingly desirable as Porsche transitions toward electrification.
