2005 Porsche Boxster S (987)

Maximum output of the 3.2-litre six-cylinder in the Boxster S is 206 kW (280 bhp), ensuring acceleration to 100 km/h in 5.5 seconds and a top speed of 268 km/h or 166 mph. To capitalise on this extra power, the Boxster S comes with a new six-speed manual gear-box, new multiple synchromesh and optimised gear travel ensuring not only a very precise, but also very fast gearshift (approximately 15 per cent faster than before).

More Dynamic Suspension, Optional Active Dampers

Benefiting from its modified suspension, the Boxster S conveys this extra power even more effectively to the road. Larger wheels with a new generation of tyres and wider track allow an even more sporting driving experience. Wheel diameter on the Boxster S is 18 inches, with 19-inch wheels available as an option.

An absolute highlight in the roadster segment is Porsche Active Suspension Management (PASM) available as an option: Simply by pressing a button, the driver can set the dampers to various positions ranging from sporting/comfortable to ultra-dynamic, in the process improving both long-distance touring comfort and the car’s behaviour when driven to the limit in terms of driving dynamics.

More Precision, More Safety: Variable Rack-and-Pinion Steering

The new rack-and-pinion steering with a variable transmission ratio improves handling at large steering wheel angles particularly on fast, winding roads. Somewhat more indirect transmission around the central position ensures a very high standard of driving stability at high speeds, and adjustment of the steering wheel not only for reach, but also for height by 40 millimetres or almost 1.6" provides ideal conditions for a perfect position at the wheel. As an option, the Boxster S is available not just with a special sports steering wheel, but also with a multifunction steering wheel complete with integrated buttons for controlling the CD-radio fitted as standard as well as optional “Porsche Communication Management” (PCM) and the telephone module.

Driving Closer to the Limit with Porsche’s Sports Chrono Package

Porsche has developed the Sports Chrono Package particularly for the driver wishing to enjoy the agile potential of the Boxster S even more to the extreme. Incorporating more dynamic engine control maps and strategies, the Sports Chrono Package pushes the car’s limits even further. A clear sign of distinction characterising the Package is the analogue/digital stopwatch on the instrument panel enabling the driver to compare his speed to an accuracy in the range of hundredths of a second.

Brake System Featuring Ceramic Discs for the First Time

Brake discs measuring 318 millimetres (12.52") at the front and 299 millimetres (11.77") at the rear, naturally cross-drilled and inner-vented as standard, ensure supreme deceleration in the Boxster S. To further improve brake response, Porsche’s development engineers have increased the transmission ratio of the brake servo by 18 per cent, helping in the process to reduce pedal forces.

The Boxster S comes as an option with Porsche Ceramic Composite Brakes (PCCB) featuring even larger (350 millimetres/13.78"), but lighter brake discs made of ceramics. This material is absolutely rustproof and subject to far less wear and tear on the road, while main-taining a high and, in particular, consistent frictional coefficient at all times.

Comprehensive Restraint System with Head Airbags

Featuring the world’s first head airbags in an open car, the Boxster S sets new standards also in terms of passive safety. The airbags protect the occupants in a collision from the side by moving up instantaneously from the doorsill beneath the side window. In the process they interact with a thorax airbag on the outside of the backrest. Together with the two full-size frontal airbags, Porsche’s roadster thus offers a highly effective safety system supplemented by belt latch tensioners and belt force limiters.

Sophisticated Interior

The interior of the Boxster S combines clear and stylish lines with a compact binnacle above the instrument cluster and the centre console further improved for even better ergonomics. Exclusively on the Boxster S, the three circular dials come with a light-grey face. The interior itself is finished in high quality materials of an even higher standard than before. The range of leather trim is even larger than on the 2.7-litre model, and additional interior features are finished in aluminium look.

Boxster S - Pole Position

In its second generation, the Boxster S again sets a new standard: Unladen weight of 2966 lb, together with maximum output of 280 bhp, provides a power-to-weight ratio of 4.80 kg/bhp making Porsche’s mid-engined roadster the No 1 performer in this discipline quite elementary to a sports car. This outstanding figure clearly proves the agility of the Boxster S in responding to the driver’s commands.

Taking the usual figures for acceleration and flexibility, this means acceleration to 60 mph in 5.5 seconds continuing just as impressively at a higher speed range, with the Boxster S accelerating from 62 to 124 mph in fifth gear in just 19.4 seconds.

Boxer Engine Developed to an Even Higher Standard

This supreme performance is attributable in particular to the updated and modified 3.2-litre power unit. Operating in conjunction with optimised supply of fresh air and exhaust emission management, the modified intake system ensures extra power and pulling force at low and medium engine speeds.

A new feature is the twin-chamber distributor pipe with its directly connected distributor butterfly for extra torque at low engine speeds, boosting torque substantially from just 1500 rpm. The advantage at higher speeds is obvious, considering the maximum torque of 236 lb-ft between 4700 and 6000 rpm. To further optimise the flow of gas within the engine system, an exhaust manifold guides the exhaust emissions into modified, ultra-low-resistance silencers in new geometric design.

The exhaust gas treatment system complete with advance and main catalytic converters, in turn, cleans exhaust emissions to a degree of purity better than the EU 4 and LEV II (USA) standards in their respective regions.

Optimised Suspension for Even More Dynamic Performance

Eighteen-inch wheels measuring 235/40 ZR 18 at the front and 265/40 ZR 18 at the rear, wider track and the precisely tuned suspension enhance the standard of driving pleasure in the Boxster S to an even higher level than before. Systematic reduction of weight through the use of new aluminium components on the chassis ensures an even higher standard of sporting performance and provides even greater safety reserves with motoring comfort remaining quite outstanding.

This superiority comes in particular from an innovative generation of tyres able to convey much higher forces to the road. In combination with the wider track, the new tyres also help to reduce body sway to the side when driving to the extreme. The special handling of the Boxster S now comes out even better than before thanks to the new rack-and-pinion steering with its variable transmission ratio: When driving straight ahead, the car responds just as smoothly and forgivingly as before, even at very high speeds. And at the same time the new steering makes the Boxster S even more direct and agile under severe movements of the steering wheel, for example on a fast country road with successive bends and turns.

A Unique Option: the Active Damper System

A genuine innovation in the sports roadster segment is Porsche Active Suspension Management (PASM) available as an option. The basic principle of this suspension lowered by 10 millimetres or 0.4" is the continuous, automatic adjustment of the four dampers re-set electrically as a function of driving dynamics and the road surface.

Pressing a button on the centre console, the driver is able to choose from two suspension programmes offered by PASM: The Normal mode offers a more comfortable basic setting changing automatically to an increasingly sporting mode the more dynamically the driver moves his car. The big advantage for the driver and his passenger particularly on long motorway trips is a significant improvement of driving comfort. The Sports mode, in turn, activates a harder damper control map for a much more agile style of motoring. When subject to extreme bumps and very unsmooth road surfaces, the system switches over to the more comfort-oriented setting. This not only makes the ride smoother for the driver, but also prevents the wheels from “jumping" on the road surface and thus serves to further enhance the car’s high level of active safety.

Brakes with Even More Powerful Boost

The brake system featured on the Boxster S has been further optimised to reflect the increase in engine power: Power assistance has been increased by 18 per cent in the interest of lower brake forces and an even faster brake response. The monobloc fixed-calliper brakes finished in red on the Boxster S and featuring four pistons on each wheel come with brake discs measuring 318 millimetres (12.52") in diameter at the front and 299 millimetres (11.77") in diameter at the rear.

An Exclusive Option: Ceramic Brakes

Porsche Ceramic Composite Brakes (PCCB) available as an option on the Boxster S open up a new dimension of brake technology in the roadster segment.

With ceramic brake discs measuring 350 millimetres or 13.78" in diameter on all four wheels and with composite brake linings, this highly advanced technology interacting with yellow-painted six-piston aluminium fixed callipers on the front wheels and four-piston aluminium fixed callipers on the rear wheels ensures a high and, in particular, consistent frictional coefficient. The result is very short stopping distances even from high speeds and under heavy loads.

The Boxster S comes with the latest evolution of this absolutely rust-free brake system featuring further enhanced and even more robust brake discs.

Exemplary Active and Passive Safety

The wide range of active and passive safety features in the Boxster S comprises nearly all systems as standard. It also includes Porsche Stability Management (PSM) enhanced to an even higher level as well as rollbars, seat belts with belt latch tensioners, belt force limiters and six airbags. The head airbag hidden beneath the side sills on the doors is one of the most innovative and outstanding airbag systems in the world. Featured for the first time in an open car, the head airbag is activated together with the thorax airbag in a collision from the side, moving up instantaneously and inflating within milliseconds to form a kind of flat cushion.

Sports Chrono Package

The Sports Chrono Package featured for the first time as part of Porsche Stability Management (PSM) offers an optional sports mode allowing even greater wheel spin and enhanced lateral dynamics on the road. A further feature of the Sports Chrono Package is the very sporting set-up of other systems within the car, including a steeper gas pedal control map and a “harder" speed governor cutting in more abruptly.

The Sports Chrono program also allows the driver to check the dynamic benefits of this unique system down to the last hundredth of a second: The sign of distinction proudly borne out on the Sports Chrono Package is the activation button in the centre console as well as an analogue/digital stopwatch on the instrument panel controlled from the lever on the steering column and enabling the driver, as just one example, to time his laps on the race track with optimum precision.

Sophisticated Ambience

Apart from the modified instrument cluster with three circular instruments and instrument faces finished in light grey especially on the Boxster S, the newly designed centre console ensures a sophisticated, high-quality interior. Typical features on the Boxster S are the wider range of leather and aluminium-look fittings as well as the alarm system featured as standard.

The lower seating position, the steering wheel now adjustable also for height, the pedals moved further to the front, as well as greater fore-and-aft adjustment of the seats are significant benefits particularly for the tall driver. The newly designed seats offer more space and better side support. In all, the Boxster S is available with no less than four different types of seats: Apart from the standard seats with Alcantara on the centrepiece, there are also the electrically adjustable seats complete with lumbar support, the leather sports seats with enhanced side support, and the new, adaptive sports seats with individually adjustable side elements on both the bottom and the backrest.
