When the latest Cayman and Boxster adopted the 718 nomenclature, they gave up something in return: their flat-six powertrains. Though Porsche's sweet six-cylinder lived in on the 718 Cayman GT4 and 718 Boxster Spyder, lesser variants employed an admittedly punchier, though mournfully bland turbocharged four-cylinder. An available manual gearbox and stirring driving dynamics have kept the 718s sharp in their sports car segments, but Porsche purists crave acoustic character.

Now it's back. With the introduction of the 718 Cayman GTS 4.0, Porsche's naturally aspirated flat-six returns in a sub-$90,000 middleweight model. With a set of adaptive dampers and more accommodating seats, the GTS 4.0 appears to be a daily driver's alternative to the racier Cayman GT4. But is the high-revving boxer-6 enough to convince shoppers to shell out extra coin over competitors like the BMW M2 CS, Audi TT-RS, and Chevy Corvette? Miles shares his thoughts in this in-depth review.

Forget all hypercars, this is my dream car

[jamesjin]

With how current motor journalism mostly measures a car’s performance in terms of straight-line acceleration, this review accentuates the sheer importance of suspension, brakes, tyres, and so many other factors of a car’s holistic performance. I am extremely glad that Porsche hasn’t given up striving to not only increase numbers but also refine what’s beyond those numbers. These reviews are always a breath of fresh air.

I don’t know why other car YouTubers spend so little time on the exterior from different angles. Thx MilesPerHr! 👍

That sport response button is basically an overtake mode just like in F1.
pretty neat

You did a great job reviewing this GTS in different situations: in spirited drive, in normal mode as a daily driver, start-stop system... etc. All the other reviews only stated how the long gear ratio puts the car as a bad daily driver, you will be speeding in 3rd gear. However they were driving in Sport or Sport plus mode. As you have demonstrated, in Normal mode, it was in 7th gear at about 55mph. Your review single handedly relief my concern about the long gear ration issues. And you are the only one that showed the manual seat adjustment. Thank you very much.

I'm trading in my c8 z51 for a 24 cgts 4.0 coming in.. I like the Vette but I'm driving a computer.. I don't want a computer. I don't want electronics are the perception I have a computer controlling me. I get a smile on my face in any of the caymens... The c8 is a comfy Cadillac.

I never liked Porsche’s until a buddy of mine bought one; and man, it change my mind completely.

The best detailed car review i’ve seen, and i subscribe to a lot.

[PrimitiveMLG]

This car is the real deal. Although in SoCal I think I go Boxster on this. That experience with the roof off and sound is even better.

[rodrigorojasgarcia]

Best review I’ve seen of a cayman nice job explaining important details of the car

[filomaster]

Better car doesnt exist on this planet, you cant deny facts

[danielpfister]

Great video 🤓!!! Last February 2023, I acquired my new 718 Cayman GTS 4.0 which has the 4L NA flat six cylinder engine (same unit as a GT4) and a PDK gearbox. Power output (394 bhp) and torque (317 lb-ft) are a nice match to this car's sensible curb weight (~3200 lbs). The color is Gentian Blue metallic with a black/chalk all-leather interior and silver wheel rims. It's definitely an entertaining driver's car!

So far, I've only done 452 miles but hopefully a lot more this coming Summer! The PDK is also a lot of fun (it's definitely quick) 🤓

All the best and thanks again from Colorado!

I’m currently in the market for the same car. As yet, this is the only Miami Blue I’ve seen in a GTS, so I like the rarity of it. Plus, in the sun it puts a smile on your face. Think that GTS pack with the white stitching looks perfect. Yes the interior is a bit dated, but it’s a small price to pay, and I kinda like it. I’m sure the next electric cayman will have all the new electronics, but I like that this is a drivers focussed car, is sold on the car itself.

Nice review and you can't beat Silverado/Modjeska canyon. Back in the early 70s I used to run my Datsun 510 out there. I'm looking forward to doing it in the Cayman...:)

[foreverflying]

Great review…I hope to have one ordered next week. I love my 2021 Macan S, but really want the more sports car like experience of the Cayman GTS 4.0…and who can resist the beautiful, yet simple lines of this car.

[amauta]

Wow. I’m in love. Had. 2019 base cayman loved it. I imagine the extra 94hp make a heck of a difference.

[luisfelipemartinezmejia]

Great review! Thanks to this review I ordered mine yesterday in the same color.

[Youtubewontletmecomment]

Awesome review…can’t believe I watched the entire thing. Awesome car as well.
