The 2007 Porsche 911 Targa 4S features a unique roof system that provides their occupants with a panoramic view even when the top is closed. The Targa’s roof is made from two glass panels and extends across the full width and length of the passenger compartment, from the windshield header to the leading edge of the engine cover and from side frame to side frame. In other words, the entire roof is glass, and in combination with the windshield and side windows provides a panoramic vantage and protection from the elements.
Both glass panels are made from a specially formulated glass that absorbs nearly all ultraviolet radiation yet remains transparent. The glass also is formulated not to transmit the sun’s heat into the vehicle. The top includes an integrated power shade that can be positioned to provide a screen against bright sunlight or insulation against cold temperatures. In addition, the front portion of that glass roof slides open at the touch of a switch to provide a large opening above the driver and front-seat passenger.
Targas are the Only 911s with Hatch-style Access
Meanwhile, the rear section of the Targa top comprises a separately opening hatchback-style access to the car’s four-seat interior and especially to the 8.1 cubic feet (230 liters) of storage area behind the rear seatbacks. Of the various versions of the Porsche 911, the Targa is the only one with a separately opening tailgate.
The Targa roof is further differentiated by a polished aluminum exterior trim strip that extends along the edge of the roofline, up from the base of the A pillar and arching along the edge of the roof side support and back to the base of the C pillar. This bright trim gives the Targa 4 and Targa 4S a unique side view among all versions of the Porsche 911.
First Targas to Offer Choice of Engines
Porsche first produced a Targa-style roof for the North American market for the 1967 model year. The unique roof style was created in response to early government safety regulations that threatened the future of the traditional canvas-roofed convertible body style.
The introduction of the all-new 2007 Porsche 911 Targa 4 and 911 Targa 4S marks the first time the Porsche Targa has been available with the customer’s choice between two power sources – the 325-horsepower 3.6-liter horizontally opposed six-cylinder engine in the 911 Targa 4 and a 355-horsepower 3.8-liter “boxer” six in the 911 Targa 4S.
The 20007 Porsche 911 Targa 4 accelerates to 62 miles per hour in 5.3 seconds and reaches 100 mph in less than 12 seconds on its way to a top speed of 174 miles per hour. The 2007 Porsche 911 Targa 4S, which comes with Porsche Active Suspension Management technology (optional on the Targa 4), reaches 62 mph in just 4.9 seconds, hits 100 in 11.2 seconds and has a top speed of 179 mph.
First Targas Built on Wide-body, All-wheel-drive Platform
The introduction of the all-new 2007 Porsche 911 Targa 4S also marks the first time that this panoramic roof has been featured on the wide-bodied and all-wheel-drive version of the Porsche 911. Regardless of engine selected, all 2007 Targa models feature all-wheel drive for enhanced driving dynamics. The cars’ larger and flared wheel arches provide room for a widened track and larger wheels and tires that are part of Porsche’s all-wheel-drive powertrain that enhances dynamic capabilities in all conditions, but especially in inclement weather.
The Targas also are equipped with enhanced Porsche Stability Management (PSM) technology featuring advanced braking systems engineered to provide the shortest possible stopping distances, a dynamic category in which all Porsche vehicles are among the best in the world.
Torque split to the front wheels automatically adjusts between 5 and 40 percent to maintain superior traction. By sending no more than 40 percent of power to the front wheels, the four-wheel-drive 911s exhibit dynamic characteristics similar to the rear-drive versions, thus they will not understeer or “push” toward the outside over the front wheels in turning maneuvers.

For 2008, the big news for the Porsche 911 range is the addition of an all-new Turbo Cabriolet model, joining the Turbo Coupe that was introduced for 2007. All other model-year 2007 variations continue into 2008, for a total of 14 models in the regular production 911 family.
Also available is the ultra-high-performance GT2, a race-ready but street-legal version of the GT3 RS.
A new option for most models is folding leather sports bucket seats, which are essentially race seats with a folding backrest. Reinforced with carbon fibre, they are seven to nine kg lighter than the standard seats, but still have integrated head and thorax side airbags.
The regular 911 line-up consists of the Carrera and Carrera S; Carrera 4 and Carrera 4 S; Carrera Cabriolet and Carrera Cabriolet S; Carrera 4 Cabriolet and Carrera 4 S Cabriolet; Targa 4 and Targa 4 S; GT3 and GT3 RS; and Turbo and Turbo Cabriolet.
All 911 models use six-cylinder, horizontally-opposed “boxer” engines. A 3.6-litre, 325-horsepower version appears in the Carrera, Carrera 4, and Targa 4 models. A 3.8-litre, 355-horsepower version is used in the Carrera S, Carrera 4 S and Targa 4 S models. The Turbo uses a turbocharged 3.6-litre that makes 480 horsepower. The GT3 uses a naturally-aspirated 3.6-litre that produces 415 horsepower, while the GT2 uses a turbocharged version of that engine to produce 530 horsepower and 505 ft-lb of torque.
All models use a six-speed manual transmission. It can be optioned to a five-speed Tiptronic automatic with manual shift mode in everything but the GT3 and GT2 models, which are strictly stick-shift.
Features on the Carrera include 18-inch alloy wheels, automatic climate control, four-piston calipers with ventilated brake discs, hydraulic power-assist steering, head and thorax side airbags, anti-theft system with interior sensor, keyless entry, heated mirrors, Porsche Stability Management system, rain-sensing wipers with heated washer nozzles, tire pressure monitoring system, three-spoke leather-wrapped wheel, on-board computer, heated seats with power-adjustable backrest, storage shelf, lockable glove-box and storage compartment, Porsche Communication Management with 5.8-inch colour display, Bose Surround Sound CD stereo, garage door opener, cruise control, illuminated vanity mirrors, black instrument dials, power windows, Alcantara headliner, and automatic extending rear spoiler. The Coupe includes a power-operated sliding steel sunroof, while the Cabriolet adds a power top and safety bars.
The all-wheel drive Carrera 4 and Carrera 4S models have corresponding features (S models use 19-inch wheels), while the Targa models include a glass roof made from two large panels running from the windshield to the engine cover. The transparent glass absorbs almost all ultraviolet radiation and does not transit heat into the vehicle; the front portion can be opened electrically, and the roof includes an integrated power shade.
The Turbo models add 19-inch alloy wheels, all-wheel drive, red six-piston calipers, enhanced Porsche Stability Management system, self-levelling bi-Xenon headlamps with washers, auto-dimming side and rear-view mirrors, Sport Chrono package, electrically-adjustable seats with driver’s side memory, full leather interior, navigation system, and aluminum-colour instrument dials.
The GT3 includes 19-inch alloy wheels, climate control, limited-slip differential, six-piston front and four-piston rear red brake calipers, three-spoke GT3 wheel with Alcantara rim, bi-Xenon headlamps, on-board computer, sports seats with Alcantara inserts and electric backrest adjustment, cruise control, CD stereo, power windows, exterior Aerodynamic package with fixed biplane wing, and sports exhaust system with central dual tailpipes. The available GT3 RS has a slightly wider rear body, split rear-suspension wishbones and carbon fibre parts, including the front lid and rear wing.
The GT2 includes 19-inch wheels, automatic climate control, Porsche Active Suspension Management, limited-slip differential, ceramic composite brakes with yellow calipers, three-spoke GT2 wheel with Alcantara rim, keyless entry, tire pressure monitoring system, on-board computer, sports seats with Alcantara inserts and electric backrest adjustment, CD stereo, cruise control, power windows, Aerodynamic package with fixed biplane wing, titanium sports exhaust system, and power-operated sliding steel sunroof.
Porsche might have adopted the name Targa after the famous Targa Florio road race before any other manufacturer for their 1966 (1967 model) Porsche Targa, but it was the English sports car company Triumph, which first used the system in their 1961 TR4. Unfortunately for them, they called it the “Surry Top”.
Porsche were far more business minded than the small English company and took out a trademark on the “Targa” name. From that moment on, all other manufacturers in the sports car business were forced to come up with alternative names for their removable tops.
But it’s the Porsche Targa, which has survived all these years, and the new 2009 Targa 4 and Targa 4S, with their removable glass roof, is a masterpiece in design and visually, the most unique 911.
Looking down onto the car from some height – the entire roof is glass. That’s 1.54-square metres in two distinct pieces. The front section of the roof slides back beneath the fixed rear glass panel exposing driver and passengers to open space measuring 0.45 square metres.
Opening time for the roof is a fast seven seconds and as standard kit, you also get a new sunblind offering more privacy than on the previous model while opening and closing (electrically) independently of the sliding glass roof section.
And for those rightly concerned about the effects of the sun, there is no need to panic. The glass is anti-sunglare and will protect you from UV radiation and with some heat reduction.
Porsche only build fast cars and these two siblings are no exception. The Targa 4 packs a new 3.6-litre flat-six engine with direct fuel injection and punches out 254kW with a top speed of 284 km/h.
The 4S is powered by the beefier 3.8-litre powertain, which produces 283 kW and will propel this car onto the supercar speed of 297 km/h.
And if you’re thinking about ordering the Targa with the optional Tiptronic gearbox, forget it. Porsche have developed their own version of a fast shifting double-clutch transmission they are calling PDK or Porsche-Doppelkupplung. Not sure of the actual shift times in milliseconds but it is said to be a full 0.2 seconds quicker in the 0-100 km/h run than the standard six-speed box, and with better fuel economy and less emissions.
Traction and stability has also been enhanced on the new Targa variants with the introduction of the Porsche Traction Management (PTM). It’s an electronically controlled system, which replaces the previous all-wheel drive with viscous multiple-plate clutch.
