The Porsche Cayman stands as a benchmark in the sports car world, blending razor-sharp handling, potent powertrains, and timeless design. Since its debut, this mid-engine coupe has captivated drivers with its balance and agility, evolving through generations to incorporate turbocharged efficiency and naturally aspirated thrills. This guide unpacks the essential facts and figures that define the Cayman, from base models to track-focused variants.
Origins and Model Lineup Evolution
Introduced as a coupe counterpart to the Boxster, the Cayman arrived in 2005, marking Porsche’s entry into accessible high-performance mid-engine vehicles. The first generation (987) featured naturally aspirated flat-six engines, with the base model delivering 245 horsepower from a 2.7-liter unit and the S variant pushing 295 horsepower from 3.4 liters. These cars set the tone for exceptional chassis dynamics, earning praise for their communicative steering and poise.
The 981 generation (2013-2016) refined this formula, boosting outputs to 261 horsepower in the base 2.7-liter and 311 in the 3.4-liter S model. Innovations like the PDK dual-clutch transmission enhanced shift speeds and daily drivability. The 718 era, launched in 2016, shifted to turbocharged flat-four engines for the base and S trims, prioritizing low-end torque while reintroducing flat-six power in GTS and GT models.
Today, the 2025 718 Cayman lineup spans from the entry-level model at $72,800 MSRP to the extreme GT4 RS at $164,200, offering choices for street and track.
Powertrain Breakdown: Engines That Define Performance
Porsche’s signature boxer engines lie at the heart of the Cayman. Early models relied on naturally aspirated flat-sixes, prized for their high-revving character. The 2009 facelift introduced direct injection, improving efficiency and power.
The 718 generation brought turbocharged flat-fours: the base 2.0-liter produces 300 horsepower and 280 lb-ft of torque, while the Cayman S ups this to a 2.5-liter with 350 horsepower and 309 lb-ft— a record torque increase for the lineage, available from 1,900 rpm for instant responsiveness. For purists, the GTS 4.0 revives a 4.0-liter naturally aspirated flat-six with 394 horsepower and 317 lb-ft, and the GT4 RS escalates to 493 horsepower with 331 lb-ft, borrowing tech from the 911 GT3.
| Model | Engine | Horsepower | Torque (lb-ft) |
|---|---|---|---|
| 718 Cayman Base | 2.0L Turbo Flat-4 | 300 | 280 |
| 718 Cayman S | 2.5L Turbo Flat-4 | 350 | 309 |
| 718 Cayman GTS 4.0 | 4.0L NA Flat-6 | 394 | 317 |
| 718 Cayman GT4 RS | 4.0L NA Flat-6 | 493 | 331 |
Transmissions include a precise 6-speed manual or the lightning-fast PDK, with the GT4 RS favoring manuals for raw engagement.
Acceleration and Top Speed Benchmarks
The Cayman’s performance figures underscore its supercar credentials. The base 718 Cayman sprints 0-60 mph in 4.7 seconds, reaching 171 mph top speed. The S model shaves this to around 4.2 seconds with PDK, while the GTS 4.0 hits 3.8 seconds and 182 mph. The GT4 RS is the standout, achieving 0-60 in 3.2 seconds and a 196 mph top speed.
Historical context reveals progression: the original Cayman needed 5.8 seconds for 0-60, improving to 4.6 seconds in the 981 S. Track prowess shines too, with Caymans dominating events like the 2013 Rolex 24 at Daytona, sweeping the podium thanks to mid-engine balance.
- Base Cayman: 0-60 mph: 4.7s, Top Speed: 171 mph
- Cayman S: 0-60 mph: ~4.2s (PDK), Top Speed: ~177 mph
- GTS 4.0: 0-60 mph: 3.8s, Top Speed: 182 mph
- GT4 RS: 0-60 mph: 3.2s, Top Speed: 196 mph
Dimensions, Weight, and Chassis Dynamics
Compact yet spacious, the Cayman measures 175.5 inches long, 71.9 inches wide, and 50.0 inches tall, with a 97.8-inch wheelbase for planted cornering. Curb weight hovers around 3,251 lbs for the base, lighter in GT variants through carbon fiber and stripped interiors.
The mid-engine layout, with the flat boxer behind the cabin, delivers near-perfect 50/50 weight distribution. This, combined with adjustable suspension and optional Porsche Active Suspension Management (PASM), yields telepathic handling. Cargo space includes 5 cubic feet front and 10 rear, practical for a sports car.
Fuel Efficiency and Real-World Range
Modern turbos enhance economy without sacrificing thrill. EPA ratings for the base Cayman are 21 city/27 highway mpg, with the S at 19/25. Real-world tests show 32 mpg on highways for both base and S. Manuals slightly trail automatics, but PDK optimizes efficiency. The GT4 RS prioritizes power over mpg, rating 16/23.
These figures make the Cayman viable for daily drives, a leap from thirstier predecessors.
