The 911 Targas differ from both the Carrera Coupes and Cabriolets by dint of their stunning glass tops. The all-wheel drive Targa 4 and Targa 4S are unique with roofs comprised entirely of two transparent panels. The glass extends from the windshield header back to the leading edge of the engine cover, from side frame to side frame.

This combination of glass roof panels with windshield, backlight, and side windows creates a glass canopy for the occupants that delivers total protection from the elements while offering clear, unobstructed vision in every direction.

When weather allows, the front glass panel, which completely covers the area over the front seats, may be opened like a conventional sunroof, sliding back beneath the rear glass panel. The rear glass panel is hinged and can open like a hatch, making the Targa 4 and Targa 4S the only cars in the 911 model range with this feature.

Both glass panels are made from a specially formulated glass that absorbs nearly all ultraviolet radiation yet remains transparent. A standard closable sun shade can completely cover the sliding glass panel for privacy.

New for 2009
For 2009, the Porsche 911 Targa 4 and and its higher-output variant, Targa 4S, receive a number of critical refinements.

Foremost among them are totally new drivetrains boasting new direct fuel injection engines and the availability of Porsche’s innovative double-clutch gearbox, PDK. Power from the new engines in the Targa 4 and Targa 4S is now distributed to all four wheels via the same electronically controlled Porsche Traction Management (PTM) system found on the Porsche Turbo.

The new engines deliver greater performance while using less fuel than their predecessors, thanks in large part to their direct fuel injection systems.

In lieu of the optional Tiptronic S transmission, Targa 4 and Targa 4S owners may now specify the driver-shiftable PDK. This ground-breaking seven-speed automatic transmission is lighter, more efficient and quicker shifting than the previous Tiptronic S.

The electronically activated PTM is able to vary the torque split between front and rear wheels infinitely and instantaneously for optimum road holding, regardless of conditions.

Commensurate with the increased performance potential, Porsche engineers have increased the braking ability of both the Targa 4 and Targa 4S. Night visibility is also enhanced as both cars come standard with BI-XENON™ headlights and L.E.D. driving lights, and brake- and taillights.

Interior refinements for 2009 center around the redesign of the Porsche Communication Module (PCM) which boasts a larger screen, simplified operation, optional Bluetooth® connectivity and the ability to play music from a variety of external sources.

Driver and passenger comfort and convenience have also been enhanced with the availability of ventilated front seats.
