Cayman GTS 4.0 – Is It Worth It? Drivers and Experts Weigh In (2025 Guide)

In a world of ever-rising prices, performance SUVs, and hybrid tech creeping into every corner of the market, the Porsche 718 Cayman GTS 4.0 stands out like a purist’s dream. It’s not just another sports car — it’s a naturally aspirated, mid-engined, manual-transmission coupe designed for real driving pleasure. But is it truly worth its asking price of around £74,000 (~$100,000) in 2025? Let’s break down the facts, opinions, and comparisons to see whether this Porsche still earns its stripes.


Quick Specs Overview

  • Engine: 4.0L Naturally Aspirated Flat-Six
  • Horsepower: 394 hp
  • Transmission: 6-speed manual or PDK dual-clutch
  • 0-60 mph: ~4.3 seconds
  • Top Speed: 182 mph
  • Fuel Economy: ~27 MPG combined
  • Base Price: £65,390 (~$85,000)

Expert Verdict: “Best Sports Car Under £100K”

After over 13,000 miles of long-term testing, automotive journalists unanimously agree: the Cayman GTS 4.0 is the best two-seat, mid-engined sports car available for under £100,000. In fact, many argue it offers the best overall value in the entire sports car segment, period.

Compared to more track-focused siblings like the Cayman GT4, the GTS is better suited for everyday use without sacrificing performance. It’s more comfortable, more refined on the motorway, and surprisingly practical — with dual cargo compartments, cruise control, and solid fuel economy (up to 33 mpg with a light foot).

The Engine That Stole Enthusiasts’ Hearts

At the core of the Cayman GTS 4.0 is a naturally aspirated 4.0-liter flat-six engine producing 394 horsepower. Unlike its turbocharged siblings or the entry-level 911 Carrera, the GTS 4.0 offers a linear powerband and a raw, high-revving character. According to many enthusiasts, this engine is what makes the GTS 4.0 special. “The sound, the throttle response, the emotional connection—it’s unlike anything else at this price point,” said one long-time Porsche owner.

Why Enthusiasts Love the GTS 4.0

1. The Engine: A Naturally Aspirated Masterpiece

At the heart of the GTS is the same 4.0-liter flat-six engine shared with the GT4, but tuned slightly down for daily livability. It revs to nearly 8,000 RPM with an intoxicating wail and crisp throttle response above 4,000 RPM.

2. Balanced and Engaging Driving Experience

From the steering feel to the chassis dynamics and manual gearbox, every input in the GTS feels direct and communicative. It’s the kind of analog driving purity that’s disappearing fast in 2025’s increasingly digital world.

3. Comfort Meets Performance

With adjustable drive modes, reasonable ride quality, and a minimalist interior (no cluttered steering wheel buttons here), the GTS blends GT-like comfort with sharp road manners — a rare combo.

GTS 4.0 vs 911 & GT3: Real Owners Weigh In

We turned to passionate Porsche enthusiasts on forums like Rennlist to hear how the GTS stacks up against the likes of the 911 (992) and the legendary 991.2 GT3.

Cayman GTS 4.0 vs. 991.2 GT3:

  • “How can this get better?” asked one owner after a year with the GTS.
  • Others argue the GT3 is a different beast entirely — raw, visceral, with a 9,000 RPM redline and motorsport roots.
  • Verdict? If you want a track weapon, the GT3 wins. If you want a street-focused sports car with real-world usability, the GTS 4.0 hits a sweet spot.

🗣 “GT3 is the tiger, GTS is the house cat — choose your predator.”

Cayman GTS 4.0 vs. Base 911 (992):

  • At roughly $25K less, the GTS offers more emotional appeal to purists, thanks to the naturally aspirated engine and mid-engine balance.
  • The 911 is still the “benchmark,” but turbocharging and increasing size make it less connected than previous generations.

🗣 “If you love NA engines and want the classic Porsche driving feel, the GTS is the better buy — while you still can.”

Comparing to the 911 Carrera

While the 992-generation 911 Carrera offers more straight-line speed and a more luxurious ride, many drivers prefer the Cayman GTS 4.0 for its mid-engine balance and sharper handling. Enthusiast forums are filled with comparisons, and a common sentiment is: “Aside from straight-line speed, the GTS 4.0 is better in every way.” Some even argue that the Cayman offers better practicality with two trunks and a more connected driving experience.

Is It a Good Investment?

While running costs aren’t exactly cheap, the GTS is holding its value extremely well, especially as production of naturally aspirated, manual Porsches nears its end.

Financing options (e.g., £824/month for 48 months) make it more accessible to buyers who don’t want to commit to full ownership. And with high demand and limited production, lightly used GTS models are commanding strong resale values.


Final Verdict: Is the Cayman GTS 4.0 Worth It in 2025?

Absolutely — if you’re a true driving enthusiast.

The Cayman GTS 4.0 is not just worth it — it may be one of the last great sports cars of the combustion era. It delivers an exceptional blend of emotion, performance, comfort, and practicality for under six figures. Whether you’re commuting or carving up canyon roads, the GTS brings the joy back to driving.

Still thinking about it? As one owner put it: “They’re not going to make cars like this forever.”

Frequently Asked Questions (FAQ) – Porsche 718 GTS 4.0 vs 911 Carrera

1. How long will the Porsche 718 GTS 4.0 be in production?

Porsche has indicated that the 718 GTS 4.0 will continue production until summer 2025, following a roughly two-year run after the introduction of EV variants. However, allocations are extremely limited, and many enthusiasts are finding the waitlists longer than the actual production window.


2. What are my options if I can’t get a new 718 GTS 4.0 allocation?

Many buyers are opting for Certified Pre-Owned (CPO) or lightly used GTS 4.0s. These cars are still highly desirable, and buying used may be the only realistic option if you’re looking to get one before production ends.


3. How does the 718 GTS 4.0 compare to the 911 Carrera in terms of driving experience?

  • The 718 GTS 4.0 features a naturally aspirated flat-six, often praised for its purity and high-revving character.
  • The 911 Carrera (992) uses a 3.0L twin-turbo flat-six, which is faster in a straight line but lacks the same visceral feel.
  • Many enthusiasts say the GTS 4.0 offers a more engaging experience, especially for those who prefer naturally aspirated engines.

4. Is the 911 significantly faster than the 718 GTS 4.0?

In straight-line speed, the base 911 (992) is quicker thanks to its higher power-to-weight ratio. However, the 718 GTS 4.0 holds its own and is often considered superior in handling, balance, and overall driving feel—especially on twisty roads or tracks.


5. Can you tune the 911 Carrera for more performance?

Yes, aftermarket tunes are available and can unlock significant power (e.g., +70 HP). However, tuning can be a double-edged sword:

  • Most non-factory tunes will void the drivetrain warranty (engine, transmission, etc.).
  • Some Porsche-certified dealers (like Champion) offer conservative tunes that they claim won’t void warranty—but this is not guaranteed by Porsche AG and depends on the dealership’s discretion.

6. Do you really lose your Porsche warranty if you tune the car?

Yes, in most cases. While a few dealers may turn a blind eye or offer “approved” tunes, Porsche’s official stance is that any aftermarket performance modification voids powertrain coverage. This includes:

  • Engine
  • Transmission
  • Differential
  • Axles

Proceed with caution if you plan to tune your car and care about warranty coverage.


7. How does the power-to-weight ratio of the 911 compare to the 718 GTS 4.0?

Here’s a basic comparison (approximate stock figures):

  • 911 Carrera: 485 hp / 3382 lbs = 0.143 hp/lb
  • 718 GTS 4.0: 394 hp / 3166 lbs = 0.124 hp/lb

Even with a tune, the 718 remains slightly behind the 911 in terms of straight-line performance, but the handling and driving dynamics often tip the scales in favor of the GTS 4.0 for purists.


8. Is the GTS 4.0 more practical than a 911?

Surprisingly, yes in some ways:

  • The mid-engine Cayman platform offers two trunks (front and rear), which many owners find more practical for daily use or weekend trips.
  • The GTS 4.0 also sits lower and is often seen as more agile, making it ideal for spirited driving.

9. Is the 2.5T 718 actually faster than the 4.0 off the line?

Some users report that the 2.5T turbocharged 718 can be quicker off the line than the naturally aspirated 4.0 due to torque availability at lower RPMs. However, the 4.0 delivers a more linear and thrilling high-rev experience—a key reason why it’s so beloved by enthusiasts.
