The Boxster S now comes with a new six-cylinder power unit enlarged in size by 0.2 litres. Output of this 3.4-litre with VarioCam Plus valve control is 217 kW (295 bhp), 15 bhp more than on the former 3.2-litre.Benefiting from this extra power, the new Boxster S accelerates to 100 km/h in 5.4 seconds, one-tenth of a second faster than its predecessor. Top speed, in turn, is up by 4 km/h to 272 km/h or 169 mph. And average fuel consumption of the S-model is 10.6 litres/100 kilometres, equal to 26.6 mpg Imp.
Dynamic suspension, active dampers as an option
The Boxster S comes as standard on 18-inch wheels, with 19-inch wheels available as an option. A particular highlight in the roadster segment is PASM Porsche Active Suspension Management also available as an option: Simply pressing a button, the driver is able to choose a damper setting all the way from sporting but comfortable to extremely sporting and dynamic, enhancing the car’s comfort on long distances, on the one hand, as well as its lateral driving dynamics, on the other.
Precise and safe thanks to variable rack-and-pinion steering
Particularly on active routes allowing a dynamic style of motoring, rack-and-pinion steering with a variable transmission ratio ensures very good handling with strong movements of the steering wheel whenever required. Somewhat more indirect around its central position, the steering transmission is ideal for very good driving stability at high speeds. The steering wheel, in turn, adjustable not only for reach but also for height by a margin of 40 millimetres or 1.6", is just right for an ideal seating position.
Apart from the sports steering wheel, a multifunction steering wheel with integrated buttons controlling the CD radio also featured as standard as well as optionally available Porsche Communication Management and the telephone module, comes as yet a further option.
Even closer to the limit with Porsche’s Sports Chrono Package
Porsche has developed the Sports Chrono Package particularly for the driver seeking to use the agile potential of the Boxster S to the extreme. Featuring even more dynamic engine control maps and management strategies, the Sports Chrono Package capitalises even more on the car’s extreme limits. The optical highlight symbolising the Package is the analogue/digital stop watch on the instrument panel allowing comparisons of lap times and dynamic driving exercises down to a hundredth of a second.
In combination with the revised and upgraded Tiptronic S automatic transmission featuring new hydraulic and electronic control as well as variable gearshift programs, this provides an even more intense experience of the Boxster S with all its sporting characteristics.
Brake system also with ceramic brake discs
To ensure excellent stopping power and deceleration at all times, the Boxster S comes as standard with cross-drilled, inner-vented brake discs measuring 318 millimetres or 12.51" in diameter at the front and 299 millimetres or 11.77" at the rear.
Compared with the first generation of the Boxster, the current model comes with an 17 per cent higher transmission ratio on the brake servo helping to reduce the forces required on the brake pedal.
As an option the Boxster S is also available with PCCB Porsche Ceramic Composite Brakes featuring even larger (diameter: 350 millimetres/13.78") but nevertheless lighter ceramic brake discs. This cerami c material is absolutely free of corrosion and a lot more resistant to wear in public traffic, while at the same time offering consistently high friction forces at all times.
Inside, the Boxster S excels in particular through its clear lines, the snugly configured binnacle above the instrument cluster, and the centre console enhanced to an even higher level of ergonomic perfection. The three instrument dials come with a light-grey face exclusively on the Boxster S.
The interior also boasts an even higher standard of materials, with a wider range of leather upholstery and trim than on the 2.7-litre and additional interior features in aluminium look. Yet a further improvement for the new model year is the position of the service dish within the luggage compartment, where the openings for filling up coolant and engine oil are now housed beneath an easily accessible lid allowing even better use and greater convenience in the rear luggage compartment.
A typical feature characteristic of the Boxster is the instrument cluster with three instrument dials in aluminium colour. The faces of the dials themselves are finished in light grey specifically on the Boxster S.
Other features typical of the Boxster S are the enhanced range of leather and aluminium trim as well as the alarm system included in the car’s standard equipment.
A low seating position, the steering adjustable for height, pedals moved further to the front, and the wide range of fore-and-aft seat adjustment benefit above all tall drivers and passengers. The seats themselves offer very ample space and side support, with no less than four “families" of seats being available: Apart from the standard seats with alcantara on the centrepiece, the customer has the choice of seats with all-electric adjustment and a lumbar support, leather sports seats with enhanced side support, as well as new adaptive sports seats featuring individually adjustable side supports at the bottom and on the backrest.
Yet another feature further enhanced for the new model year is the position of the service dish in the luggage compartment: The openings for coolant and engine oil are now housed together beneath an easily accessible lid, allowing even better and more convenient use of the rear luggage compartment.
Powered by a new 217 kW (295 bhp) 3.4-litre flat-six and offering a power-to-weight ratio of 4.7 kilos per horsepower, the Porsche Boxster S sets the standard not only in driving dynamics. Performance is of course exceptional thanks to the very good ratio between weight and power, the Boxster S with its six-speed manual gearbox featured as standard accelerating to 100 km/h in just 5.4 seconds.
And in its second-highest gear, Porsche’s open mid-engined athlete takes just 6.6 seconds to accelerate from 80-120 km/h or 50-75 mph. Top speed, finally, is 272 km/h or 169 mph, 4 km/h faster than on the former model. Larger engine and VarioCam Plus
Enlarged in size from 3.2 to 3.4 litres, the power unit of the Boxster S develops its maximum output of 295 bhp at 6250 rpm, thus offering 15 bhp more than its predecessor. Maximum torque of the 3.4-litre, in turn, is now 340 Nm or 251 lb-ft maintained consistently in a speed range between 4400 und 6000 rpm (so far: 320 Nm or 236 lb-ft from 4700 rpm). At the same time the new Boxster S outperforms the EU 4 and ULEV II (USA) emission limits and offers average fuel consumption of 10.6 litres/100 kilometres, equal to 26.6 mpg Imp.
The 3.4-litre flat-six is based on the former 3.2-litre with VarioCam valve control. While stroke remains unchanged at 78 millimetres or 3.07", bore is now 96 millimetres or 3.78", as in the Carrera engine. The cylinder heads also come in full from the 911 Carrera, just like VarioCam Plus valve management combining precise adjustment of valve timing on the intake camshaft (VarioCam) with switching cup tappets (Plus).
Thanks to this technology, the new power unit in the Boxster S offers superior characteristics combining powerful acceleration with high peak power and low fuel consumption.
Realigned Tiptronic S
Entering the new model year, the Boxster S is available as an option with Porsche’s upgraded and refined Tiptronic S automatic transmission featuring new hydraulic and electronic management.
This new automatic comes with variable gearshift programs and, particularly in combination with the optional Sports Chrono Package, offers exceptionally sporting driving characteristics: With the sports button activated, for example, the transmission only shifts up and down above 3000 rpm and shifts down under braking at far lower deceleration and at higher engine speeds. The gearshift is very sporting in character, gearshift times are shorter, and in the manual mode the Sports Chrono Package prevents the transmission from shifting up when reaching the engine cut-off speed.
Sports Chrono Package
Combined with the optional Sports Chrono Package, PSM comes with a special sports mode offering more slip and an even higher standard of lateral dynamics. A further feature of the Sports Chrono Package is the particularly sporting set-up of other systems within the car, including a steeper gas pedal control map and harder engine speed cut-off.
The Sports Chrono program also enables the driver to check his lap times and dynamic driving performance down to the last hundredth of a second. The Package itself is visibly displayed by the activation button in the centre console and an analogue/digital stop watch on the instrument panel masterminded via a lever on the steering column and serving to take lap times and check other factors, as required by the driver.
Chassis and suspension for even greater driving dynamics
The Boxster S comes on 18-inch rims running on 235/40 ZR 18 tyres at the front and 265/40 ZR 18 tyres at the rear. The outstanding pleasure of driving the Boxster S also results from the wide track and the very precise set-up of the suspension with aluminium components serving to keep unsprung masses to a minimum.
In its superior handling, the Boxster S is further enhanced by rack-and-pinion steering with a variable transmission ratio to the benefit of the driver: When driving straight ahead, the car continues to respond smoothly to slight movements of the steering wheel, also at very high speeds. When moving the steering wheel harder, on the other hand, as is required when driving more dynamically on a country road, the steering is direct and agile.
A unique option: active suspension management
PASM Porsche Active Suspension Management available as an option lowers the entire car by 10 millimetres or almost 0.4 inches and therefore offers two suspensions in one. The sytem incorporates dampers adjustable electrically for their response and varied continuously and automatically as a function of driving and road conditions.
A button on the centre console allows the driver to choose among two different suspension programs: The Normal mode offers a sporting but comfortable damper set-up automatically changing to a more sporting mode as soon as the driver changes over to a more dynamic style of motoring. The result is superior motoring comfort particularly on long journeys on the Autobahn or motorway. In the Sports mode, on the other hand, harder damper control lines allow a particularly dynamic and agile style of motoring, switching over to a more comfortable setting on extremely bumpy roads – which means not only greater comfort, but also better tyre grip on the road and, as a result, active safety enhanced to an even higher standard.
Even more servo power on the brakes
The Boxster S features a brake system with truly exemplary performance free of fading. The boost effect of the power brakes was indeed increased by 17 per cent when changing over to the new model generation in late 2004, helping to reduce forces on the brake pedal and ensure a faster brake response. The monobloc fixed-calliper brakes finished in red on the Boxster S and each featuring four pistons come with 318-millimetre (12.52-inch) brake discs at the front and 299-millimetre (11.77-inch) discs at the rear.
A truly exclusive option: ceramic brakes
PCCB Porsche Ceramic Composite Brakes available as an option on the Boxster S offer a brand-new dimension in brake performance in the roadster segment. Comprising ceramic brake discs measuring 350 millimetres or 13.78" in diameter on all four wheels as well as composite brake callipers, this special package interacting with six-piston aluminium fixed callipers on the front wheels and four-piston alu m inium fixed callipers at the rear, all finished in yellow, ensures a very high level of consistent brake power at all times.
The result is very short stopping distances even under high brake loads. And last but not least, the Boxster S benefits from the latest stage in evolution of these corrosion-free brakes with further enhanced, even more robust brake discs.
Exemplary active and passive safety
The comprehensive package of active and passive safety features in the Boxster S comprises nearly all systems and functions as standard. These include PSM Porsche Stability Management developed to an even higher level, as well as rollbars, belts with belt latch tensioners and belt force limiters, and no less than six airbags. The head airbags concealed beneath the side window sills in the doors are inflated in a collision from the side together with the thorax airbag, moving up and forming a flat safety cushion within milliseconds.
Comprehensive restraint system with head airbags
Featuring head airbags in an open car, the Boxster S also sets new standards in passive safety. The head airbag protects the occupants efficiently in a collision from the side by inflating instantaneously out of the sill beneath the side window. This effect is then supplemented by a thorax airbag inflating in the outer section of the seat backrest.
Together with the two full-size frontal airbags, Porsche’s Roadster therefore offers a very sophisticated and comprehensive safety and protection system enhanced by belt latch tensioners and belt force limiters.
