Porsche Cayman GT4

The Porsche Boxster and Cayman are mid-engine two-seater sports cars manufactured and marketed by German automobile manufacturer Porsche across four generations—as a two-door, two-seater roadster (Boxster) and a three-door, two-seater fastback coupé (Cayman).

The first generation Boxster was introduced in 1996; the second generation Boxster and the Cayman arrived in late 2005; and the third generation launched in 2012. Since the introduction of the fourth generation in 2016, the two models have been marketed as the Porsche 718 Boxster and Porsche 718 Cayman.

The nameplate ''Boxster'' is a portmanteau, and '' roadster'', a reference to the body style. The nameplate ''Cayman'' is an alternative spelling of caiman, a member of the alligator family.

Overview

Boxster

The Porsche Boxster is a mid-engine two-seater roadster. It was Porsche's first road vehicle to be originally designed as a roadster since the 914. The first-generation Boxster (the 986) was introduced in late 1996; it was powered by a 2.5-litre flat six-cylinder engine. The design was heavily influenced by the 1993 Boxster Concept. In 2000, the base model was upgraded to a 2.7-litre engine and a new Boxster S variant was introduced with a 3.2-litre engine. In 2003, styling and engine output was upgraded on both variants.

Production of the 986 began at the former 928 facility in Stuttgart, Germany in 1996. Valmet Automotive also manufactured Boxsters under contract to Porsche at a facility in Uusikaupunki, Finland. The Boxster was Porsche's biggest volume seller from its introduction in 1996 until the introduction of the Cayenne sport utility vehicle in 2003. As of September 2012, additional production of the Boxster started at the former Karmann-factory in Osnabrück.

In 2005, Porsche debuted the second generation of the Boxster, the type 987, with a more powerful engine and styling inspired by the Carrera GT. Engine output increased in 2007, when the Boxster models received the engines from their corresponding Cayman variants. In 2009, the Boxster models received several new cosmetic and mechanical upgrades, further increasing engine output and performance. The third generation Boxster (type 981) was launched at the 2012 Geneva Motor Show.

Cayman

First launched in 2005 for the 2006 model year, the Cayman is a coupé derived from Porsche's second and third generation Boxster roadster, styled in its first iteration by Pinky Lai. All Caymans were manufactured in Finland by Valmet Automotive. As Volkswagen assumed control of Porsche AG, production of Caymans and Boxsters after 2012 began in the former Karmann plant in Osnabrück, Germany, at the time owned by Volkswagen and also used for production of the 2012 Golf (Mk6) convertible.

The car is not named after the Cayman Islands. Both the car and the islands are named after the caiman, a member of the alligator family. When the Cayman arrived at dealerships for sale, the automaker adopted four caimans at Stuttgart's Wilhelma Zoo.

Porsche brought an infringement lawsuit in 2009 against Crocs, the maker of the popular rubber shoes. At issue was the footwear company's clog name also called Cayman. An injunction was granted against Crocs Europe, a division of the Longmont, Colorado-based shoe company preventing their use in Germany of the Cayman name.

718

Introduced in 2016 for the 2017 model year, the Porsche Boxster and Cayman were renamed the Porsche 718 Boxster and Porsche 718 Cayman (internally called the 982), reviving the historic 718 moniker while switching engines from naturally-aspirated flat sixes to small-displacement flat-four turbocharged units. The new 718 Cayman was also repositioned with an entry price lower than that of the 718 Boxster, in keeping with Porsche's higher pricing for roadster models.

First generation: Boxster (986) (1996–2004)

Grant Larson's design, inspired by the 356 Cabriolet, Speedster, and 550 Spyder, stimulated a commercial turnaround for Porsche. Through consultation with Toyota. Porsche began widely sharing parts among models and slashed costs.

By October 1991 following a visit to the Tokyo Motor Show, Porsche in dire straits, began to devise solutions to succeed the poor selling 928 and incoming 968 (a heavy update of the 944). In February 1992, Porsche began development of a successor to the 928 (mildly updated for 1992) and recently released 968. By June 1992, out of 4 proposals based on dual collaboration between the 986 and 996 (993 successor) design teams, a proposal by Grant Larson and Pinky Lai was chosen by Harm Lagaay. In August 1992, a decision was made to develop the concept into a show vehicle, in time for the 1993 North American International Auto Show. After garnering widespread acclaim from the press and public upon presentation of the Boxster Concept in January 1993, the final production 986 production exterior design by Larson was frozen in March 1993. However, by the second half of 1993, difficulties arose with fitment of some components, resulting in lengthening of the hood and requiring another design freeze by fourth quarter of that year. Prototypes in 968 bodies were built to test the mid-engine power train of the 986 by the end of 1993, with proper prototypes surfacing in 1994. Pilot production began in the second half of 1995, ahead of series production in mid-1996.

The Boxster was released ahead of the 996. The 986 Boxster had the same bonnet, front wings, headlights, interior and engine architecture as the 996.

All 986 and 987 Boxsters use the M96, a water-cooled, horizontally opposed ("flat"), six-cylinder engine. It was Porsche's first water-cooled non-front engine. In the Boxster, it is placed in a mid-engine layout, while in the 911, the classic rear-engine layout was used. The mid-engine layout provides a low center of gravity, a near-perfect weight distribution, and neutral handling.

The M96 engines had a number of failures, resulting in cracked or slipped cylinder liners, which were resolved by a minor redesign and better control of the casting process in late 1999. A failure for these early engines was a spate of porous engine blocks, as the manufacturer had difficulty in the casting process. In addition to causing problems with coolant and oil systems mingling fluids, it also resulted in Porsche's decision to repair faulty engines by boring out the cast sleeves on the cylinders where defects were noted in production and inserting new sleeves rather than scrapping the engine block. Normally, the cylinder walls are cast at the same time as the rest of the engine, this being the reason for adopting the casting technology.

The model received a minor facelift in 2002. The plastic rear window was replaced by a smaller glass window. The interior received a glove compartment, new electro-mechanical hood and trunk release mechanism (with an electronic emergency release in the fuse box panel) and an updated steering wheel. Porsche installed a reworked exhaust pipe and air intake. In addition, the front headlight's amber indicators were replaced with clear indicators. The rear light cluster was also changed with translucent grey turn signals replacing the amber ones. The side marker lights on the front wings were changed as well from amber to clear, except on American market cars where they remained amber. The bumpers were also changed slightly for a more defined, chiseled appearance, and new wheel designs were made available.

Second generation: Boxster/Cayman (987.1) (2005–2008) & (987.2) (2009-2012)

The second generation of the ''Boxster'' debuted at the 2004 Paris Motor Show with the (997) 911 and became available for sale in 2005.

Revised styling included modified headlights, larger side intake vents and enlarged wheel arches to allow wheels up to 19 inches in diameter. Interior revisions included a more prominent circular theme for the instrument cluster and cooling vents. The base engine is a 2.7-litre flat-six boxer engine, with the Boxster S getting a 3.2-litre engine. For 2007, the base Boxster received a revised engine featuring VarioCam Plus and the Boxster S engine was upgraded from 3.2-litre to 3.4-litre. These upgrades made the Boxster series and the Cayman series equivalent in terms of power. The 987 is the last generation of the Boxster and Cayman series with hydraulic steering.

The ''Cayman'' S fastback coupé (987c) was first unveiled and went on sale in late 2005. The base Cayman followed in July 2006.

Both the Cayman and second generation Boxster roadster share their mid-engine platform and many components, including the front fenders and trunk lid, doors, headlights, taillights, and forward portion of the interior. Styling incorporates cues from the 356/1, the 550 Coupé and the 904 Coupé. The Cayman's hatchback enables access to luggage areas on top of and in the back of the engine cover. The suspension design is fundamentally the same as that of the Boxster with revised settings due to the stiffer chassis with the car's fixed roof.

The Cayman S was powered by a 3.4-litre flat-six mated to a 6-speed manual transaxle, a 2.7-litre engine with a 5-speed transmission was standard for the base model. An electronically controlled 5-speed automatic (Tiptronic) was also available on the S and base models.

The Boxster and Boxster S models received a facelift in 2008. Changes included an increase in engine displacement to 2.9-litre for the Boxster, incorporation of Direct Fuel Injection (DFI) for the Boxster S. Both models now came standard with a new 6-speed manual gearbox and were available with a 7-speed ''Porsche Doppelkupplungsgetriebe'' (PDK) dual clutch gearbox. Cosmetic changes included new head and tail lights, larger front air intakes with incorporated day time running lights, and an altered lower rear end flanked by twin diffusers.

A facelift of the Porsche Cayman followed in February 2009. As with the Boxster, the base Cayman's engine displacement was increased to 2.9-litre while the Cayman S gained direct injection. Both the Cayman and Cayman S maintained a power advantage over their roadster sibling, the Boxster. A limited slip differential was now a factory option.

Third generation: Boxster/Cayman (981) (2012–2016)

The third-generation Boxster (internally known as the 981) was announced on 13 March 2012 at the Geneva Motor Show with sales starting in early summer 2012. The 981 Boxster 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 Boxster features a new, 40 per cent more torsionally rigid chassis, the front track is wider, the rear wider and the wheelbase extended by , but with a small weight reduction of up to compared to the previous type 987 Boxster.

The standard Boxster was fitted with a new 2.7-litre flat-6 engine, and the Boxster S was 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 were 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 claimed 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 from the 3.4-litre engine.

The third generation Cayman was unveiled at the 2012 Geneva Motor Show. The production version of the 981 Cayman 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-litre engine, and in the S trim with a 3.4-litre engine. Both versions are available with either a 6-speed manual or a dual-clutch 7-speed PDK transmission.

The 981 Cayman features upgrades including a new body, a longer wheelbase, a wider front track, electrically powered steering, and a redesigned interior that matches the firm's contemporaneous 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-litre version of the 911.

Fourth generation: 718 Boxster/Cayman (982) (2016–present)

With the new 982-generation, the marketing designation of the Boxster and Cayman was changed to Porsche 718, a nod to Porsche's racing heritage that won the Targa Florio race in 1959 and 1960. Because the 718 Cayman / Boxster has lost two cylinders, going from a naturally aspirated flat-6 engine to a turbocharged flat-4 engine, the name is meant to evoke a racing series that was won by a light car which outmaneuvered the cars with more powerful engines.

The timeline of the 718 release started in 2016, with first model availability scheduled for June. The 718 base models featured two new horizontally-opposed flat-4 turbocharged engines of 2.0-litre and 2.5-litre displacements with increased torque and horsepower along with lower fuel consumption. The S model's turbocharger utilises Variable Turbine Geometry (VTG) technology. The Boxster S could accelerate from in 4.1 seconds, and the Cayman S in 3.9 seconds. In October 2017, the GTS models were announced with their 2.5-litre engines upgraded to .

In 2020, the GTS 4.0 model of both the Boxster and the Cayman was released with a new engine, a slightly de-tuned version of the 4.0-litre naturally aspirated six-cylinder boxer engine found in the GT4. In the GTS 4.0 trim the engine is rated at and of torque. The GTS comes standard with a six-speed manual gearbox, -20 mm sport suspension and a mechanical limited slip differential.

The exterior of the 718 Boxster and Cayman is very similar to the third generation, in fact more of an evolution than a redesign. The most notable changes are to the rear of the car, which now has a long black-trim bar across the rear connecting the two taillights. The headlights and bumper are also heavily reworked. On the sides, the mirrors have been redesigned, taking cue from the SportDesign mirrors on the GT3. Porsche also began offering additional exterior color options including Miami Blue, Chalk, and Graphite Blue Metallic.

The interior remains very similar to the 981 Cayman / Boxster and the 991.2 generation of the Porsche 911. The main change is the new PCM 4.0 infotainment system, which replaces the PCM 3.1. The steering wheel comes with a mode selector switch that includes a selection of Sports and Sports Plus driving modes, resulting in snappier throttle response at the cost of fuel efficiency. Overall, the most prominent design features of the 981 Cayman / Boxster remain, including large air induction ports on the side, and the prominent horizontal aluminum piece used for adding oil and coolant in the trunk.

Despite the loss of two cylinders, the 718 Cayman / Boxster are mechanically superior to the 981 model; acceleration is faster and steering is improved according to ''Top Gear'' and ''Motor Trend''. In spite of the view of some that the new engine "cheapens the experience", the 718 Cayman was declared ''Motor Trend's'' 2nd best Drivers car in 2017, which praised the car's handling and throttle response. Giving the award, Miguel Cortina noted, "The suspension is just what you want to feel in a car like this—stiff, sporty, rigid. You get a very good sense of what is happening on the road."

In 2021, Porsche unveiled the 718 Cayman GT4 RS, the first Cayman to receive the RS treatment which is usually reserved for the 911 models. With a 4.0 naturally aspirated flat-six derived from the 911 GT3, it puts out and which allows it to sprint from in just 3.4 seconds. It generates 25% more downforce than the GT4 variant, through a swan-neck attachment fixed rear wing. The GT4 RS lapped the Nürburgring Nordschleife 23 seconds faster than the GT4.

Mechanical issues and lawsuit

Boxster models manufactured between 4 May 2001 and 21 February 2005 have suffered engine failure due to a fault with the intermediate shaft (IMS) bearing, which resulted in a class action lawsuit against Porsche Cars North America (referred to as ''Eisen v. Porsche Cars North America''). A settlement was agreed in March 2013, subject to court approval. Some say IMS bearing failure issues are not limited to the model years covered in the settlement, or to the Boxster.

On March 5, 2019, Porsche issued a recall on 14,388 718 Caymans and Boxsters, due to a luggage compartment bracket that could puncture the fuel tank in certain collision instances.
