Redesigned headlights and a smaller steering wheel are fine, but the most important changes are found under the rear decklid. Like the Coupe and Cabriolet, both the 911 Targa 4 and 4S are equipped with Porsche's new 3.0-liter flat-six powerplant. Displacement is lower than before, but the addition of two turbochargers makes up for it, and the final result is more power and more torque (not to mention up to 12 percent higher efficiency).
The base model Targa 4 produces 370 horsepower and 331 pound-feet of torque, while the 4S adds modified compressor wheels, a new exhaust, and a new engine tune to bump peak output to 420 horsepower and 368 pound-feet of torque. A seven-speed manual transmission comes standard on both models, while Porsche's indispensable seven-speed dual-clutch PDK is optional.
All in all, the heavier Targa models only take an extra 0.2 seconds to reach 60 mph compared to the Coupe. Even more impressive is the fact that, for the first time ever, this AWD 911 accelerates quicker than its RWD equivalent (not including the monster 911 Turbo, of course).
Of course, being a Targa, you get that unique open-top style, complete with silver Targa-bar B-pillars and wrap-around rear window glass. All together, the Targa offers the suggestion of a roofline when viewed in profile, which to my eye, looks far better than the topless Cabriolet. It's unlimited headroom, but in a more graceful package.
Yes, the 911 Targa is for showmen (and women), but it delivers on its styling promise with an exceptional driving experience which is hard to beat, even with, dare we say it…a turbo in the boot.
The Targa is at its best on an open, sweeping road with the sun beating down. The cabin is spacious up front, and buffeting with the roof down is kept to a minimum. It's beautifully built, too, with loads of soft leather and a responsive touchscreen infotainment system.
Sporty not kitschy, practical not fanciful. The five round instruments have one purpose above all: to provide information. They do so efficiently and accurately with a styling that you would expect from Porsche, and a rev counter that's right in the middle. With the 'GTS' logo on the dial. The instrument cluster with high-resolution 4.6-inch colour screen delivers a continuous stream of data from the on-board computer.
What's the use of inner drive without a clear objective? It's all the more important to have an interior that lets you concentrate on the essentials. By giving you quick access to all the information you need while you're driving. A particularly sporty interpretation of this idea is the mode switch on the GT Sport steering wheel, which enables you to choose from four driving modes.
One final option of note is the electro-hydraulic lift feature, which increases front ground clearance by 40 mm (1.57 inches). Push a button, and five seconds later you'll be able to navigate speed bumps and angled driveways without scraping that finely chiseled, road-hugging Porsche chin.
Finally, keeping it all rubber-side-down is the standard Porsche Active Suspension Management (PASM) system, which comes with new shock absorbers and lowers the ride height by 10 mm (0.39 inches), all in the name of striking a balance between comfort and sportiness.
There's also Porsche's Dynamic Light System offered as an available option, which comes with speed-sensitive beam-range adjustability, adverse weather functionality, and a pivot function that helps to illuminate around corners. Finally, there's the Porsche Dynamic Light System Plus, which comes with LEDs, plus an automatic high/low beam function.
