718 Cayman with two-liter, turbocharged flat four-cylinder engine delivering 300 hp. 718 Cayman S with 2.5-liter, turbocharged flat four-cylinder engine with VTG (variable turbine geometry) making 350 hp. Both engines make 25 more horsepower than their respective predecessor. The new powertrains also make up to 67 lb.-ft. more torque, which is available below 2,000 rpm, greatly increasing performance and usability in everyday driving situations.
With the new turbo engines, the 718 Cayman models offer superior acceleration and throttle response thanks to the Dynamic Boost function. The 718 Cayman with PDK and Sport Chrono Package accelerates from zero to 60 miles per hour in 4.5 seconds (0.6 seconds quicker than the previous model). With the same equipment, the 718 Cayman S takes just 4.0 seconds (0.4 seconds quicker than before). The top track speeds are 170 and 177 miles per hour, respectively. When equipped with the Sport Chrono Package, the PSM features a new Sport Mode with a higher threshold of intervention to suit performance-oriented drivers on enclosed tracks.
More important than the increase in horsepower is the torque advantage of the new engines. The two-liter engine of the 718 Cayman makes 280 lb.-ft. of torque (an improvement of 67 lb.-ft. ), which is available from 1,950 to 4,500 rpm. The 2.5-liter engine in the 718 Cayman S delivers up to 309 lb.-ft. of torque (37 lb.-ft. more than the previous Cayman S) from 1,900 to 4,500 rpm. This is the greatest torque increase in the history of the Porsche Cayman and gives the car a much higher level of usability, performance and responsiveness in rpm ranges that drivers use every day. The engines can rev up to 7,500 rpm, and retain about 95 percent of their power from 6,500 rpm to the redline, both characteristics reminiscent of naturally aspirated high-performance engines. During spirited driving, the driver is thus given the option of enjoying the free-revving nature of the engine and shifting through the gears, or to use the generous amount of torque available from low engine speeds throughout a large rpm range.
Comprehensively advanced design. Only the luggage compartment lid, roof and windshield have been left unchanged. The front fascia has a sharper profile, which gives the front of the car a wider and more muscular appearance. Redesigned rear fascia appears wider due to the high-gloss black accent strip with integrated Porsche logotype. New clear glass tail lights with four-point brake lights.
The design of the new 718 Cayman emphasizes the close relationship with the 718 Boxster. Apart from the roof and rear trunk lid, the two bodywork versions are closer than ever before visually – similar to the 911 Coupe and Cabriolet models. Viewed from the side, the 718 Cayman stands out thanks to its striking fenders and sill covers. With its even more clearly defined edge, the indentation in the door leads to the redesigned air intakes with 2 vanes. The enlarged air intake cover is another indication of the 718 Cayman’s increased performance. The rear fenders are less arched, emphasizing the width of the 718 Cayman. There is also a revised choice of wheels. The 718 Cayman comes standard with an 18-inch wheel, while the 718 Cayman S is fitted with a 19-inch wheel. Other 19- and 20-inch wheels are optionally available.
The interior picks up on the exterior’s consistent emphasis of horizontal lines and is characterized by an even higher quality and functionality that is typical for Porsche. The impressive leather trim has stitching which continues to the storage compartment. With its elevated air vents, the redesigned upper part of the dash panel reflects the distinguished three-dimensional exterior design. A sport steering wheel in the design of the 918 Spyder measuring 14.8 inches (375 millimeters) in diameter is standard. The 14.1 inch (360 millimeter) GT Sport steering wheel is available as an option. Porsche offers multifunction and steering wheel heating as options for all steering wheel versions.
Comfort doesn’t have to be sacrificed. Neither does a sporty driving feel. The optional fully electric Sport seats offer power adjustment of seat height, backrest angle, squab angle and squab depth. Also electrically operated are the fore/aft adjustment, four-way lumbar support and even the steering column. The included memory package stores a range of settings, including the positions of both exterior mirrors and all driver’s seat and steering wheel positions.
The 718 Cayman now employs the brake system that was previously used in the Cayman S, with front brake rotors measuring 13 inches (330 millimeters), representing a 0.6 inch (15 millimeter) increase compared to the previous model. The 718 Cayman S is equipped with the new four-piston calipers and thicker brake rotors (34 millimeters instead of 28 millimeters) of the 2017 911 Carrera on the front axle. The Porsche Ceramic Composite brake system (PCCB) with rotors measuring 13.8 inches (350 millimeters) at all four wheels is available as an option. The 718 Cayman models also come standard with the multi-collision braking system. The system can reduce the severity of a secondary collision by automatically braking the vehicle after an initial collision triggering an airbag deployment.
The 718 Cayman can be ordered with new and improved assistance systems. Adaptive Cruise Control (ACC, option) now has a coasting function in conjunction with the PDK transmission. When driving in a queue of vehicles the clutches are disengaged, thus saving fuel by coasting. The optional Lane Change Assist monitors the driver’s blind spots and areas to the rear of the vehicle on both sides. Active as of 20 miles per hour, a visual signal in the corresponding door mirror warns the driver that a vehicle has been detected in the adjacent lane.
