Highlights of the New 911 Targa 4 / Targa 4S

A Wonderful View

The new Targa is a very special 911 – a Porsche 911 with a glass roof extending all the way from the windscreen frame to the centreline at the rear, plus high-gloss-polished, eloxy-plated aluminium trim strips extending all the way along the roofline from the A-pillars to the bottom of the C-pillars, both of these features making this special version of the 911 quite unique and very different.

The roof itself is made up of the sliding module at the front and a separately opening rear window. The sliding section opens up half a metre at the touch of a toggle button in the centre console, gliding elegantly beneath the rear lid.

Lighter glass roof with integrated roll cover

Further enhanced and developed to an even higher standard, the glass sliding roof is made of special glass and is 1.9 kilos or 4.2 lb lighter than on the former model. It efficiently ab­sorbs almost all ultraviolet radiation, but is nevertheless highly transparent and permeable to light. The integrated roll cover is opened and closed by the two-stage toggle switch con­trol­ling the glass roof and offers additional protection from bright sunshine or cold temperatures.

911 with a hinged rear window

Like its predecessor, the new 911 Targa 4(S) is the only version of the 911 to once again feature a separately opening tailgate made of glass. The tailgate is unlocked by remote con­trol from the car key or by pressing a button on the driver's doorsill, swinging up smoothly to an angle of 60o when subsequently pushed slightly by hand. Once open, the tailgate pro­vides convenient access to the large, 230-litre (8.1 cubic feet) luggage compartment behind the front seats.

First Targa available in two different variants

The new Targa is the first model of its kind available with both current versions of the 911 power unit: The customer has the choice of either the 911 Targa 4 developing maximum output 325 bhp (239 kW) or the 911 Targa 4S with peak power of 355 bhp (261 kW).Top speed is the same as on the 911 Coupé versions of the Carrera 4 and Carrera 4S, with the 911 Targa 4 reaching a top speed of 280 km/h or 174 mph, the 911 Targa 4S an even more impressive 288 km/h or 179 mph.

All-wheel drive for even greater driving dynamics

The new Targa is based for the first time on the Carrera 4 with all-wheel-drive technology. As a result of this sophisticated all-wheel-drive system and the viscous multiple-plate clutch, the front wheels convey a minimum of five per cent of the engine's power at all times and, if required, up to 40 per cent of the drive power to the road. This benefits in particular the car's driving stability in bends, directional stability at very high speeds, and of course driving dynamics on difficult surfaces.

Suspension with or without PASM

Yet another new option on the Targa is the choice of two suspension variants: Proceeding from the steel-spring chassis, Porsche offers the enthusiast PASM Porsche Active Suspen­sion Management optional on the 911 Targa 4 and standard on the 911 Targa 4S. Through this variable damper setting, PASM allows the driver to choose either a sporting but comfor­table or a dynamic and truly firm suspension set-up.

Wide chassis dimensions for enhanced comfort and sporting performance all in one

Based on the broad stance of the all-wheel-drive suspension, both versions of the Targa offer a comfortable set-up with driving characteristics even more sporting and dynamic than on the former model. Wider track at the rear ensures an even higher potential in terms of late­ral acceleration and, through greater sway support, serves to enhance both driving dyna­mics and motoring safety.

Body width 44 millimetres or 1.73" wider at the rear than on the rear-wheel-drive versions of the 911 Carrera allows the use of large and muscular wheels: The Targa 4 comes with 295/35 ZR 18 tyres at the rear, the Targa 4S features even larger 305/30 ZR 19 tyres.

Six airbags for all-round protection

Occupants enjoying the new Targa models with all-wheel drive are able to enjoy all the passive safety features likewise fitted as standard in the other current versions of the 911 Carrera. Apart from driver and front passenger frontal airbags, these include, inter alia, the Porsche Side Impact Protection System (POSIP) with thorax airbags at the outside of the seat back­rests and head airbags in the doors.

The New 911 Targa 4 / Targa 4S

Outstanding and Elegant all in One

The Porsche 911 Targa 4(S) is now entering its next generation full of elegance, power and performance. The large roof made of tinted glass as well as the new high-gloss-polished aluminium trim strips on the side edges of the roof are the first eye-catcher. Another design feature typical of the Targa is the side windows tapering out to a sharp angle at the rear and giving the Targa its characteristic, sleek and stretched silhouette. And then of course there are the widely flared wheel arches, with the new Targa for the first time boasting the wider body of the Carrera 4 models broadened at the rear by 44 millimetres or 1.73" and giving this elegant sports car truly impressive and highly dynamic looks.

Two model variants for the first time

For the first time in its more than 40-year history, the Porsche 911 Targa is available with two engine variants: The Targa 4 is powered by a 3.6-litre six-cylinder boxer developing maxi­mum output of 325 bhp (239 kW) and accelerating this thoroughbred sports car from 0-100 km/h in 5.3 seconds, all the way to a top speed of 280 km/h or 174 mph. The 3.8-litre boxer engine in the 911 Targa 4S, in turn, churns out maximum power of 355 bhp (261 kW), accelerating the car from standstill to 100 km/h in just 4.9 seconds and sufficient for a top speed of 288 km/h or 179 mph.

Large sliding roof and hinged rear window

The Porsche Targa is characterised in particular by its large glass roof. The complete glass area measures 1.54 square metres in size and is split up into two segments, the sliding roof and the hinged rear window.

The large glass sliding roof is opened and closed by a toggle switch in the centre console, opening up by sliding beneath the rear window to an open area of 0.45 square metres within just seven seconds – approximately twice the roof opening area in the 911 Carrera Coupé with its steel sliding roof.

The roof module of the 911 Targa 4 is made up of two layers of special tinted glass 1.9 kilos or 4.2 lb lighter than on the former model. The sliding roof comes as standard with a roll cover extending when closed over the entire sliding roof area, opening and closing as requi­red either together with the glass roof or by itself at the touch of the two-stage toggle switch in the centre console.

Both the glass roof and the rear window come in tinted glass protecting the occupants from UV radiation and heat even in bright summer sun. As on the former model, the tailgate opens separately via a button on the driver's door cutout or by remote control from the car key, and is supported when closing by an electrical closing aid.

All-wheel drive now also for the Targa

Based on its new body configuration carried over from the 911 Carrera 4, the Targa for the first time comes exclusively with all-wheel drive. Central power division is ensured by a vis­cous multiple-plate clutch permanently feeding variable power between five and 40 per cent of the engine's full output to the front wheels, depending on driving conditions and the road surface.

This gives both versions of the Targa well-balanced drive power and traction in bends all the way to the extreme limit, very good directional stability up to top speed, and enhanced driving dynamics at all times.

Refined and sporting suspension

Both the 911 Targa 4 and 911 Targa 4S come with a suspension set-up combining superior comfort with equally superior sportiness. PASM Porsche Active Suspension Management optionally available on the 911 Targa 4 and standard on the 911 Targa 4S offers a sporting but comfortable damper set-up in the Normal mode and switches over to a dynamic and firm set-up once the driver presses the Sports button. In both positions the suspension ad­justs consistently to the driver's style of motoring and road conditions, thus varying its con­trol and operation maps within fractions of a second.

The 911 Targa 4 comes with 8J x 18 wheels running on 235/40 ZR 18 tyres at the front, the 911 Targa 4S features 8J x 19 wheels and 235/35 ZR 19 tyres. The rear wheels offer an even larger contact area, running on 295/35 ZR 18 tyres in the case of the Targa 4 and 305/30 ZR 19 tyres on the Targa 4S.

Ceramic brake discs and Sports Chrono Package Plus as an option

Both the 911 Targa 4 and the 911 Targa 4S come with aluminium monobloc fixed calliper brakes with four pistons each as well as cross-drilled, inner-vented brake discs on all four wheels. As an option, both cars are available with PCCB Porsche Ceramic Composite Brakes featuring composite ceramic discs approximately 50 per cent lighter than comparable brake discs made of grey-cast iron. The advantage is quick, substantial and consistent decelera­tion as well as abrasion reduced to a minimum.

Like the other models in the range, the Porsche 911 Targa 4 and 4S are also available as an option with Porsche's Sports Chrono Package Plus for the particularly sporting driver, offering an extra-dynamic set-up of various functions. To activate the program, all the driver has to do is press the sports button in the centre console, giving engine management, PSM Porsche Stability Management, PASM Porsche Active Suspension Management, and the Tip­tronic S automatic transmission an even more sporting and dynamic set-up.

Extra-safe passenger cell

The inner roof structure in the 911 Targa 4(S) ensures superior safety and stability at all times. As on the 911 Carrera Cabriolet, 30-millimetre (1.18") thick tubes made of ultra-strong steel reinforce the A-pillars. Welded directly on to further tubes extending along the edge of the roof and resting on the body of the car via the B-pillars and at the bottom of the C-pillars, these special tubes ensure very good protection of the occupants even in a rollover.

Like all Porsche sports cars, the Targa comes as standard inside with Porsche's comprehen­sive airbag system featuring a total of no less than six airbags for maximum safety.

Sophisticated equipment and individual options

In terms of both equipment and ergonomics, both versions of the new Targa are largely iden­tical to their sister models in the 911 model series. Reflecting the elegant shape of the roof in the 911 Targa, however, Porsche's designers have created new roof linings. The windscreen frame, for example, comes with modified sun visors adapted to the shape of the roof.

Both the 911 Targa 4 and the 911 Targa 4S are available with a wide range of leather uphol­stery and trim comprising both the seat centrepieces, the side supports, and the headrests on the front seats.

Further standard features are automatic air conditioning as well as PCM Porsche Communi­cation Management complete with an integrated radio, CD-player, and nine loudspeakers. And last but not least, Porsche offers a wide range of options for customising the car, such as the BOSE Surround Sound System, the Porsche ParkAssistant, or the electronic logbook.

The New 911 Targa 4 / Targa 4S

Elegance and Clear Perspectives

The individual character of the new Porsche 911 Targa is more distinctive and sophistica­ted than ever before. Indeed, the design features setting this unique sports car clearly apart from the other models in the current generation of the 911 are truly unique and outstan­ding. Particular highlights are the new, high-gloss-polished and eloxy-plated aluminium trim strips extending along the edge of the roof from the A-pillars to the bottom of the C-pillars. Beneath the elegant roofline, in turn, the side window areas taper out in a sharp angle, ex­pressing a design highlight typical of the Porsche Targa. As a result, the glass roof area ex­tends all the way from the windscreen to the tail section behind the rear seats.

With the Targa changing in its proportions, the car now looks even more dynamic and power­ful then before: The wide track of the rear axle with its muscular, extra-broad wheel arches shows clearly that the Targa is based on the chassis of the 911 Carrera 4 with all-wheel drive. This technical update offers advantages in driving dynamics and allows Porsche's engineers to re-set the entire driving behaviour of the 911 Targa.

The latest model in the 911 Series is available in two variants – the 911 Targa 4 and the 911 Targa 4S. The “basic" version is powered by a 3.6-litre boxer engine developing maxi­mum output of 325 bhp (239 kW) and sufficient for a top speed of 280 km/h or 174 mph. Displacing an even larger 3.8 litres, the power unit of the 911 Targa 4S provides maximum output of 355 bhp (261 kW), giving the car an even more remarkable top speed of 288 km/h or 179 mph.

Roof and Body

Extra-Large Glass Roof with Roll Cover and Wind Deflector

The highlight of the 911 Targa is of course its glass roof measuring no less than 1.54 square metres in size. A highly effective UV filter protects occupants from excessive sunglare, allo­wing them, together with the automatic air conditioning featured as standard, to enjoy mo­to­ring even at an outside temperature of more than 30o C or 86o F.

This is attributable to the special type of glass used, the special glass coating letting through approximately one-third of the sunlight, but only about 17 per cent of the thermal energy generated in the process. So the interior always remains pleasantly bright, but not hot.

The roof module is made up of the sliding glass roof at the front complete with its integra­ted roll cover, on the one hand, and the hinged rear window, on the other. For the first time, the roof and the roll cover are opened and closed together via the two-stage toggle switch in the centre console: Whenever the driver presses the first stage and keeps it pressed down, the roll cover beneath the glass sliding roof will open and close and can be stopped in its current position at any time. Pressing the switch only briefly to the first stage, the driver moves back the roll cover alone to its final position. Pressing harder beyond a noticeable stop point, the driver then reaches the second position on the toggle switch, opening or closing the glass roof as required.

Upon opening, the roof first moves down and then to the rear, coming to rest beneath the rear window. A spring-loaded multiple-plate wind deflector opens up at the same time to keep the interior free of drafts. Measuring some 35 millimetres or approximately 1.38" in height, this wind deflector is aerodynamically optimised by its new geometry to avoid any undesired air flow.

The result is even better acoustics within the car when the roof is open. Even at high speeds, therefore, the occupants can converse easily with one another or enjoy the sound of their audio system. And last but certainly not least, the avoidance of draughts also allows driving with the roof open in winter temperatures.

Safe and light special glass

In developing the new 911 Targa 4(S), Porsche's engineers have given great attention to the glass roof made up of two-layer partially pre-stressed laminated safety glass or PLS for short. The big advantage of pre-stressed glass is that it is more resistant to objects pene­trating the car from outside.

To be precise, the glass roof is made up of two 2.6-millimetre (0.1") thick PLS panes with two layers of PVB plastic measuring 1.1 millimetres or 0.04" together in the middle.

This makes the glass roof not only a full millimetre thinner than on the former model, but also 1.9 kilos or 4.2 lb lighter. And particularly in a sports car such as the 911 Targa 4(S), weight saved in the roof area means a lot, with a lower centre of gravity ensuring greater stability against roll and sway and giving the Targa even better roadholding and grip even in fast bends.

New plate spring mounts

The new spring mounts for the roof module ensure excellent soundproofing and avoidance of sound transmission with the roof both closed and open. To achieve this effect, plate springs disconnect the glass roof mounting points and take up vibrations at the side. And since the upper glass segment is moved via cables driven by two electric motors at the rear of the car, it is impossible for any vibrations to be conveyed through this route.

The roof itself opens or closes within seven seconds, providing an opening approximately half a metre long when moved right to the rear. This, in turn, is equal to an area of 0.45 square metres, roughly twice the size of the sliding roof opening up in the 911 Carrera Coupé.

When opened, the front roof cover glides beneath the glass tailgate, with the tailgate always remaining closed when opening the roof for safety reasons. Conversely, the roof has to be closed whenever the driver wishes to open the tailgate.

Highly effective sealing system against noise and wet weather

In developing the roof and the mechanical operating system, Porsche's engineers focused not only on straightforward, smooth and unproblematic operation, but have also improved the sealing system to an even higher standard for minimum wind noise also at high speeds. A further point is that a so-called underpinning sealing system helps reliably to keep out water and moisture in no less than three different ways: The first barrier keeping out water from outside is formed by a rubber lip extend across the windscreen frame from right to left. The second countermeasure is a small gutter at the rear end of the sliding roof taking up water when the roof is opened while wet and allowing the water to run down aluminium guide rails at the side. This feature interacts with the main hose-profile seal on the edges of the glass sliding roof.

Yet a further seal is fitted, finally, on the aluminium frame further down, pressing from be­neath against the modular frame panel. With aerodynamically induced underpressure on the outer roof contour increasing as a function of speed, the glass sliding roof is then pressed harder into the underpinning seal.

The only Porsche 911 in tailgate configuration

The Targa is the only version of the Porsche 911 to feature a folding tailgate. With the rear seat backrests folded down, the tailgate offers easy and convenient access to the large, 230-litre (8.1 cubic feet) luggage compartment behind the front seats. In all, the capacity available in this storage area exceeds the capacity in the 911 Coupé by 25 litres or 0.9 cubic feet.

The rear window locking and unlocking by electric control is made of tinted, 3.85-millimetre-­thick single-pane security glass. A windscreen wiper integrated in the rear window is available as an option, and a dark frame made up of longitudinal plastic rails and aluminium cross­bars at the rear integrates the roof module elegantly into the new body of the 911 Targa 4(S).

With the car at a standstill, the driver can unlock the folding rear window either via a button on the driver's doorsill or, from outside, on a button on the car key featuring remote control.

When being opened, the rear window moves up approximately 20 millimetres or 0.8" and is then easy to swivel open further by hand. Two gas springs behind the side windows support the process of the glass tailgate moving up by approximately 60o in all. And two interior lights at the bottom of the C-pillars are switched on automatically at the same time.

Any rainwater on the tailgate is drained off when opening via the water gutter integrated in the rear end of the sliding roof.

To close the tailgate, all the driver has to do is place it on its lock, the electrical closing assistance automatically completing the closing process.

Complete glass module with its own frame

A self-bearing modular frame made of steel plate and featuring riveted aluminium guide pro­files accommodating the glass sliding roof together with its guide rails, operating motor, wind deflector, roll cover, and the folding tailgate, forms the backbone of the entire glass roof mo­dule extending from the windscreen all the way to the centre section at the rear. A crossbar between the sliding roof and the tailgate accommodates the centre joint and tail­gate seals and holds the sliding roof seal in position.

The entire roof module is fastened in position by 16 bolts at the bottom on the roof supports, the windscreen frame, and rear crossbar. The connection seams leading to the body of the car are covered at the outside by black-coloured plexiglas trim complete with rubber lips overlapping the glass elements. Inside, high-quality, sophisticated cover elements made of plastic and aluminium ensure an absolutely smooth and even transition.

Bodyshell with a steel skeleton structure inside the roof

The safety and body stiffness of the new 911 Targa 4 bodyshell are beyond the slightest doubt. Again, Porsche has opted for the proven concept of a steel skeleton made up of high-­strength tubes. Like on the 911 Carrera Cabriolet, special insert tubes made of high-strength steel and measuring 30 millimetres or 1.18" in diameter serve to reinforce the A-pillars.

In the 911 Targa 4 these tubes extend from the roof columns to the bottom of the C-pillars, junction plates serving as welding points connecting the steel tubes in the pillars with the body of the car.

The B-pillars form the third important support point for the roof of the car, extending from the side panels of the body to the roof supports and firmly welded at the top.

This construction also offers benefits in terms of styling, giving the roof supports a smooth and flowing line from the A-pillars to the end of the C-pillars without being interrupted by seams or divisions. At the same time the roofline and glass areas are skilfully laid out to pro­vide a low and sleek package as soon as the glass roof is moved to the rear beneath the tail­gate. This not only gives the interior of the new Targa an even greater impression of bright­ness and size inside, but also offers the advantage of extra headroom.

High standard of passive safety

This exceptional body stiffness also gives the Targa the right foundation for superior passive safety even in the event of a rollover.

Apart from the all-new roof structure, the new model in the 911 range naturally comes with all the safety features of the 911 Carrera Coupé, comprising, first, the energy-absorbing load-bearing structure of the body, the bumper system with its shock-absorbing effect, and the doors with defined load paths guiding impact energy into the B-pillars. Then there are also the frontal airbags for the driver and front passenger as well as the POSIP Porsche Side Impact Protection system of side and head airbags, complete with side impact protectors in the doors.
