2021 Porsche 718 Cayman Review

Andy Bornhop

By Andy Bornhop

Updated January 30, 2025

Andy Bornhop is an author specializing in new cars, trucks, SUVs, crossovers and vans. He’s been admiring wheeled conveyances since he was kid and has been writing about them professionally since his college days. While Andy admires quality, technology, efficiency, and style, he’s also a big fan of utility, practicality and refinement, and therefore can find a Sprinter van as fascinating as a Corvette. Most important to Andy, though, is how well a vehicle responds to its driver.

Pros

  • Sublime driving dynamics
  • Superb mid-engine balance
  • Potent GTS 4.0 and GT4 models
  • Great automatic transmission

Cons

  • Price builds quickly with options
  • Turbo flat-4 engine lacks character

What's New?

  • Automatic two-zone climate control
  • Heated seats
  • Auto-dimming mirrors
  • Apple CarPlay
  • Bi-xenon headlights

This mid-engine coupe, a hardtop version of the 718 Boxster, has the same dynamic talents and depth of engineering as its vaunted Porsche 911 sibling. Some enthusiasts might argue that the 718 Cayman – with its mid-engine chassis – is the ideal Porsche because it doesn’t have its engine in the trunk, and is, therefore, better balanced. And now that there are two new versions of the Cayman with 6-cylinder power, that argument is being heard now more than ever. However you feel on the subject, there’s no denying that the 718 Cayman is as comfortable everyday 2-seater than can be appreciated on the road or track.

2021 Porsche 718 Cayman Pricing

2021 Porsche 718 Cayman pricing starts at $54,547 for the 718 Cayman Coupe 2D, which had a starting MSRP of $61,250 when new. The range-topping 2021 718 Cayman GT4 Coupe 2D starts at $84,305 today, originally priced from $102,900.

Driving the Porsche 718 Cayman

The Porsche 718 Cayman is a joy on a twisty road, carving through corners with verve and powering on to the next one with good force, all while putting a smile on the driver’s face. The kinetic thrills truly are exhilarating, stirring, and satisfying.

While the Cayman shines on curvy mountain roads, it doesn’t come at the expense of good ride quality. This mid-engine Porsche is comfortable in the daily grind, and the electric-assist steering, shared with the  911 Turbo, also works well. Through the steering wheel, you get a good sense of what’s happening at the front wheels.

If you plan to exercise your Cayman at weekend track events, order a GTS or a GT4 if it’s within your budget. If not, get a T or a standard Cayman and order it with the Sport Chrono Package, Porsche Torque Vectoring (with a mechanical locking differential), and Porsche Active Suspension Management system, which offers a low-riding Sport mode. When driven hard, the Cayman with the turbo 4-cylinder is plenty quick, but the blat out of its exhaust is nowhere near as seductive as the beautiful tune emanating from the flat-6’s pipes.

Interior Comfort

Even though it’s a low-slung 2-seat coupe, the Porsche 718 Cayman manages to accommodate occupants over six feet tall. Getting in and out can be a bit awkward, but once you’re in the driver’s seat, you’ll find plenty of legroom.

The cabin itself has a classic look, but it’s far from ornate. The instrument cluster emphasizes the importance of the tachometer, which takes on more importance with the high-revving 6-cylinder engines. Materials are premium quality; fit and finish are suitably top-notch. Comfier seats, finer leathers, and multiple color schemes are available.

Storage space in the Cayman is split into two sections because of the mid-engine design. Under the hood up front is 5.3 cubic feet of cargo area; at the rear is 9.7 cubic feet.

Exterior Styling

The 2021 718 Cayman has a classic Porsche coupe profile with a long and low nose and a rounded-off cabin that slopes down to a short tail. All the lines and proportions work together. Sharp edges, bold lighting elements, and prominent side air intakes – to feed and cool the turbo engines – add a certain intensity.

Depending on the variant, the 2021 Porsche 718 Cayman runs on wheels that range in size from 18 to 20 inches.

Favorite Features

PDK 7-SPEED TRANSMISSION
The optional PDK (Porsche Doppelkupplung) dual-clutch automatic transmission shifts gears faster than any driver, and it improves acceleration times. Paddles behind the steering wheel add to the fun, as do the automatic throttle-blip downshifts that occur when you’re driving aggressively. Also, there’s no such thing as a missed shift with PDK.

SPORT CHRONO PACKAGE
The Sport Chrono Package has a dash-mounted stopwatch and four driver modes, along with a launch control function (on models with the PDK transmission). It’s optional in the base and S Caymans, but standard on all other models.

Standard Features

The Porsche 718 Cayman is a premium coupe with all the right sports car parts: supportive sport seats, a slick-shifting manual transmission, an eager mid-mounted engine, and a sublime suspension.

That stated, there are plenty of creature comforts. Two-zone automatic climate control is new this year, as are heated seats, Apple CarPlay, a 6-speaker stereo, front and rear parking sensors), and complimentary roadside assistance for four years or 50,000 miles, whichever comes first.

Factory Options

Rather than buy the base 2021 718 Cayman and add some performance hardware, it could be smarter to consider the new 718 Cayman T to access 20-inch alloy wheels, active suspension, mechanical locking differential with torque vectoring, and the Sport Chrono Package.

The 718 Cayman range offers versions with greater power, and the PDK transmission is a popular option. If there are track days on the horizon, definitely look into the ceramic-composite brakes.

Also notable: The 7-speed PDK automatic transmission now is also available on the 718 Cayman GTS 4.0 and 718 Cayman GT4 models. Porsche says these models, with PDK, are expected to arrive in early 2021.

Lane Change Assist (a blind-spot warning) continues to be a wise option, as does adaptive cruise control. Also available: 18-way power-adjustable seats and a 12-speaker/821-watt Burmester surround-sound system.

Engine & Transmission

Mounted directly behind the Cayman’s two seats are the mid-mounted engines. The standard 2021 Porsche 718 Cayman and 718 Cayman T have a turbocharged 2.0-liter flat-4 generating 300 horsepower, along with 280 lb-ft of torque coming in at 1,950 rpm.

The 2021 Porsche 718 Cayman S has a 2.5-liter flat-4 developing 350 horsepower and 309 lb-ft of torque at 1,900 rpm.

The 2021 Porsche Cayman GTS 4.0 and 718 Cayman GT4 are powered by a naturally aspirated 4.0-liter flat-6 with 394 and 414 horsepower, respectively. These 6-cylinder engines transform the Cayman into a much more serious sports car. The GT4, in case you were wondering, has a top track speed of 188 mph.

A 6-speed manual transmission is standard. All-wheel drive is not available. The PDK automatic transmission option is an excellent choice if you don’t want to row your own gears.

2021 Porsche 718 Cayman Safety

2021 Porsche 718 Cayman Safety Technology

Lane-Change Assist

This optional feature makes lane changes in the Porsche 718 Cayman much safer by letting the driver know whenever there’s a vehicle in the rear three-quarter blind spot. This should be standard.

Porsche Ceramic-Composite Brakes

With this expensive option, the Cayman is equipped with massive ceramic-composite brake discs that are extremely resistant to fade. Great for use on the track.

Porsche Active Safe

This system, in conjunction with adaptive cruise control, will warn you if the Cayman is approaching a vehicle too rapidly from behind. If the driver doesn’t react, the car will automatically apply its brakes. Once the driver takes over the braking, the Cayman automatically maximizes brake pressure for the shortest possible stopping distance.
