2018 Porsche 718 Cayman OVERVIEW

Even without the six-cylinder engines of old, the Porsche 718 Cayman remains one of the most tempting sports cars under $100,000.

What's New for 2018

Still wearing the 718 designation, the 2018 718 Cayman is mechanically unchanged from its 2017 update. Porsche has added new customization options (because there weren't enough already) like a gloss-black spoiler, contrast stitching, and two-tone leather upholstery choices. Porsche also introduced a new trim level, the Cayman GTS, which features a tweaked engine profile for a small boost in power and torque.

Choosing Your Porsche 718 Cayman

Porsche conveniently separates their trims by engine configuration, which makes choosing a Cayman a balance of performance and budget. All three engines get the same gearbox choices – a six-speed manual is standard, and Porsche’s seven-speed dual-clutch PDK is an option on all trims. All Caymans are rear-wheel drive.

The base engine is a 2.0-liter turbocharged four-cylinder making 300 horsepower and 280 pound-feet of torque. All the torque is available below 2,000 rpm to help performance and drivability. The next step up is another turbo four-cylinder in the Cayman S, this one displacing 2.5 liters and making 350 hp and 309 lb-ft. The top-of-the-line engine for the new GTS trim is a tuned version of the 2.5-liter engine, now producing 365 hp and 317 lb-ft with the PDK gearbox.

With a manual gearbox, the EPA estimates mileage for the Cayman at 21 mpg city, 28 mpg highway, and 24 mpg combined. The Cayman S is slightly worse at 20/26/22, and the enhanced Cayman GTS engine gets 19/25/21. The automatic transmission improves mileage slightly – expect a one-to-two mpg boost with the PDK option.

Porsche is all about customizability, and the Cayman is no different. A massive laundry list of options fills the configurator, dictating everything from rim size to suspension height to interior accents. To help buyers navigate, Porsche separates the Cayman into three trims: base, S, and GTS.


Even in base trim, the Cayman comes with plenty of luxury. Starting at $56,350 after a $1,050 destination fee, the base Cayman comes with automatic climate control, heated mirrors, a seven-inch infotainment display, front and rear parking sensors, a rearview camera, and xenon headlights. The 18-inch wheels are nice as standard equipment, but buyers can select any of the wheels available on the Boxster or Carrera, for a price.

The standard seats are manually adjustable and partial leather. A full leather interior is an option for $2,520 (natural leather costs an extra $1,520), and power seats cost $2,330. Bucket seats are available for $440, but to make them electrically adjustable raises the price to $3,810. To cover bucket seats in leather is an addition $830.

There are two main package options: Premium and Premium Plus. Each of these packages is subdivided into two variants, for the same price but with different seats (bucket and regular). The Premium Package ($1,370) adds power seats, automatic cornering headlights, auto-dimming mirrors with rain sensors, dual-zone climate control, and heated seats. Premium Plus ($3,180) includes all of the Premium options plus ventilated seats, keyless entry, push-button start, and ambient interior lighting. All the options in the packages are available as stand-alone options, but the packages save some dough by bundling them together.

There’s room for mechanical customization as well. Remapped low-speed power steering costs $280, Porsche’s electronic suspension control is $1,790, and electronic torque distribution is $1,320. For $7,410, Porsche will add beefy carbon fiber brakes with yellow calipers.

Technology-wise, there are only a few upgrades above the standard system. Navigation is $1,780, and two different levels of Porsche’s CarConnect will link your car and your smartphone for $1,020 or $1,720. There’s a Bose sound system for $990 or a premium Burmester setup for $4,690.

Most of the other options are cosmetic additions like model badges, spoilers, or interior trim choices. Many of these are available in packages of their own. There are a few other practical additions like a rear wiper ($370), power mirrors ($330), or a heated steering wheel ($470). For safety, buyers can add adaptive cruise control for $1,670 and lane change assist for $700.


The Cayman S starts at $68,750 and gets the 2.5-liter engine, along with 19-inch rims. There are a few cosmetic differences, and if you're looking at dealerships the Cayman S will likely be spec'd with a few more options attached. Otherwise, it’s mechanically the same as the base trim. All options and packages remain the same.


Starting at $80,850, the Cayman GTS clocks in just more than $12,000 over the Cayman S. The GTS gets the tuned version of the 2.5-liter engine and rolls on big 20-inch alloy rims. Otherwise, it’s essentially one big options package. Included are the electronic torque vectoring, a performance dashboard package, sport exhaust, powered bucket seats wrapped in faux-suede, and various black accents and model designations. All these options (except for the faux-suede) are available as stand-alone options that total to about $12,000, but with the GTS Porsche throws in the tuned engine.

CarsDirect Tip

It’s easy to go crazy on Porsche’s configurator and double the 718 Cayman's starting price. We recommend against it. If you’re looking for a blast of a sports car, the base trim is plenty – add whatever creature comforts you need and call it a day. If you must have top performance, the GTS is your best bargain.
