Porsche 911 Targa
The latest 911 Targa expands on the concept of the previous model, which introduced a large power-operated glass roof that slides under the rear window. The biggest difference from the previous 911 Targa is that the rear window in the new model is hinged, opening to provide convenient access to the rear luggage compartment.
The 911 Targa is the first 911 to feature a rear hatch opening. The glass hatch opens either by the electric release located near the doorsill or remotely from the key fob. In either case, it requires only a slight lift, and then gas-pressure struts hidden behind the window trim open it the rest of the way. When the hatch is lowered, an automatic closer pulls it fully closed.
In the 2003 911 Targa, folding down the rear seatbacks provides 8.1 cubic feet (230 liters) of cargo space, compared to 7.1 cubic feet (201 liters) in the 911 Carrera® Coupe. The increase is due mainly to different interior trim to accommodate the glass roof.
When the glass roof opens, a wind deflector deploys at the leading edge, reducing turbulence and allowing open-air driving, even in colder weather. Porsche designed the deflector to keep wind noise to about the same level as that of the 911 Carrera Coupe with sunroof. A cloth sunblind automatically extends out beneath the glass roof when closed to protect occupants from the sun’s heat and glare (glass has UV tinting, too). The blind also provides an additional layer of insulation from cold weather.
The 911 Targa shares its 3.6-liter, 315-horsepower (SAE) engine, 911 Turbo-inspired front-end styling and interior enhancements with other 911 models, including the Carrera Coupe and Cabriolet and the Carrera 4S. In profile, the 911 Targa can be distinguished by its sharply tapered rear side glass, but its coefficient of drag is the same as the 911 Carrera Coupe – 0.30.
