The Porsche 981 is the internal designation given to the third-generation Porsche Boxster/Cayman models built by Porsche. It was announced on 13 March 2012 at the Geneva Auto Show with sales starting early summer 2012. The 981 reflects the new design language from the 911 (991) and 918, and features new and revised engine and transmission specifications.

Together with a new body, the type 981 features a new chassis; 40 per cent more torsionally rigid, the front track is 40mm wider, the rear 18mm wider and the wheelbase extended by 60mm, but with a small weight reduction of up to 35 kg (77 lb) compared to the previous type 987.[10] It was the last Boxster/Cayman to feature a six-cylinder engine. Its 2016 replacement, the 982 features a four-cylinder unit.


The standard Boxster is fitted with a new 2.7-litre flat-6 engine, and the Boxster S is fitted with the existing 3.4-litre engine but with revised performance. Both engines are equipped with a 6-speed manual gearbox and an optional 7-speed reworked PDK. Both manual and automatic models are available with several technical options including Porsche Torque Vectoring (PTV) and a Sport Chrono Package that includes active transmission mounts, and makes the PDK-equipped model even faster. Porsche claims that the new generation Boxster provides fuel savings of 15% over the outgoing model.

The range was expanded in March 2014 with the addition of the GTS derivative, with slightly altered front and rear bumpers and an additional 15 bhp from the 3.4-litre engine.[11]

Boxster Spyder[edit]

Porsche revealed the latest Boxster Spyder based on the 981 Boxster in April 2015 at the New York Auto Show. The styling of the car is similar to the previous generation Spyder, continuing the twin hump rear deck and manually operated canvas top. It also shares some styling with the Cayman GT4, using the same front and rear fascia. The engine is also shared with the Cayman GT4, a 3.8 litre flat-6, making this the largest and most powerful engine used in a Boxster with 287 kilowatts (385 bhp).

It was the lightest Porsche, weighing 1,315 kilograms (2,899 lb). This was achieved through the use of aluminium doors and rear boot lid, a manually operated roof and unique lightweight 20 inch wheels. The air conditioning and audio system were also removed, although they can be added as no cost options. Braking is via larger brakes than used on the Boxster S, being 340mm front and 330mm rear units taken from the 911 Carrera S. Also shared with the GT4 is a limited slip differential combined with Porsche Torque Vectoring and features a 20mm lower ride height.

Additionally it also borrows the steering rack from the 911 Turbo S along with the same reduced diameter GT steering wheel as used in both the GT3 and GT4. The Boxster Spyder was only available with a 6 speed manual transmission. The Spyder had a base price of US$82,100 and was only available as a 2016 model with a total worldwide production of 2400 units, with 850 destined for the US.[citation needed]

Porsche Cayman S (981C)

The second generation Cayman was unveiled at the 2012 Geneva Motor Show. The production 981 was released as a 2014 model in the spring of 2013. The new car was available in both the standard trim with a 2.7 L engine, and in the S trim with a 3.4 L engine. Both versions are available with either a 6-speed manual or a dual-clutch 7-speed PDK transmission.

The 981 features upgrades including a new body, a longer wheelbase, a wider front track, and a redesigned interior that matches the firm's contemporary 911 models.

The new model gained acclaim in the motoring press as one of the best handling sports cars at any price, due to its-mid engine layout and driving dynamics. The Cayman S benefits from the same engine and running gear as Porsche's latest 3.4 L version of the 911. [16][17][18][19]

Cayman GTS[edit]

2015 Porsche Cayman GTS

The Cayman GTS was introduced in 2014, and is based on the 981 platform. It features a marginally more powerful engine, a new body kit, new 20-inch Carrera S wheels, new Bi-Xenon headlights, and a new sports exhaust system. The Cayman GTS is longer than the Cayman and the Cayman S by 1.2 inches due to its bumpers. The new, optional passive sport suspension allows the Cayman GTS to have a 20mm lower ride height compared to a car equipped with standard passive suspension or 10mm lower compared to one with the standard-equipped PASM. The engine produces 340 hp (254 kW; 345 PS), and can achieve a 0-62 mph (100 km/h) acceleration time of 4.9 seconds with the manual transmission, 4.7 seconds with PDK and 4.5 seconds with PDK and Sport Plus mode, which is activated via the now standard Sports Chrono Package. The Cayman GTS weighs 1,385 kg (3,053 lb) with the manual transmission and can attain a top speed of 177 mph (285 km/h) while the Cayman GTS with PDK can reach 175 mph (282 km/h) and weighs 1,375 kg (3,031 lb). The configuration changes made over a standard Cayman S resemble closely what Porsche did to its predecessors through Cayman S Sport and Cayman R in the 987 generation models. [20] [21]

Cayman GT4[edit]

Porsche Cayman GT4

In 2015, the Cayman GT4 was introduced, based on the then current generation of the Cayman (981C), using a revised and a slightly de-tuned version of the 3.8-litre flat-six engine from the 911 (991) Carrera S. The GT4 was available only with a 6 speed manual transmission and weighed 1,340 kg (2,954 lb). It has a vented front bumper to improve cooling for the additional radiator, with a lower lip as well as a fixed rear wing for providing downforce. Compared to the standard Cayman, it features a 30mm lower ride height, upgraded brakes from the 991 GT3, a limited slip differential combined with Porsche Torque Vectoring, and Porsche Active Suspension Management with dampers derived from the 991 GT3. A number of reinforcements were also made throughout the chassis to keep it stiff and well balanced. A Club Sport Package is also available, featuring a rear half rollcage, preparation for a battery cut off switch, a fire extinguisher and a six-point racing harness for the driver, compatible with a neck saving HANS device. Sport Chrono Package with unique Track Precision app is also available specifically for the GT4, adding an additional ECU to the car to deliver telemetry data to the driver's smartphone. In the United Kingdom, the GT4 could be ordered before its introduction at the 2015 Geneva Motor Show in March, and the first cars would arrive in dealerships in March. The Cayman GT4 has a projected Nürburgring Nordschleife lap time of 7 minutes 40 seconds[22][23] and has a top speed of 183 mph (295 km/h).[24] The GT4 has gained rave reviews from magazines like Evo and the likes of Chris Harris. The GT4 also represents the last mid-engine track focused car with a naturally aspirated Flat-6 engine coupled to a 6-speed manual transmission, a combination that would disappear after the introduction of the turbocharged Flat-4 in the 718 Cayman.

Cayman GT4 Clubsport[edit]

On 6 October 2015, Porsche announced a Clubsport version of the Cayman GT4. Developed by Porsche Motorsport, the Cayman GT4 Clubsport made its debut at the 2015 LA Auto Show in November. It is powered by the same 3.8-litre boxer 6 cylinders engine rated at 385 PS (380 bhp; 283 kW) at 7,400 rpm and 420 N⋅m (310 lb⋅ft) at 4,750 rpm of torque found on the production Cayman GT4.[25]

As opposed to the road going Cayman GT4, the Clubsport version is fitted with Porsche's PDK double clutch transmission (albeit with 7th gear disabled) with shift paddles on the steering wheel, as well as mechanical rear-axle locking differential. The Cayman GT4 Clubsport weighs only 1,300 kg (2,866 lb) and shares the same Performance Friction brakes and lightweight suspension strut front axle found on the Porsche 991 GT3 Cup. Its ABS is adjustable in 12 steps. A 100-litre FIA-approved "bag" fuel tank is available as an option for endurance racing. In addition to its lightweight features, it is supplied fitted with an FIA welded-in roll-cage, six-point harness and racing bucket seats.

Sales of the new Cayman GT4 Clubsport commenced after its debut in November through Porsche Motorsport in Weissach or Porsche Motorsport North America.
