2015 NAIAS Porsche 911 Targa 4 GTS debuts Porsche has debut the 911 Targa 4 GTS and Cayenne Turbo S at the 2015 NAIAS in Detroit. The two variants are essential for the Stuttgart-based sports car makers in its quest to attain a strong footing in world’s largest sports car and SUV market, the USA. Ever since the Type 356 was introduced in the 1950s, Porsche has appealed to a very broad-minded customer base with its vehicles in the States. Last year alone, around one-fourth of all vehicles it produced were delivered to the USA.

Now let’s look at the two NAIAS debut variants, starting with the 911 Targa 4 GTS. Marking its 50th anniversary of the 911 Targa, the new open-top 911 Targa 4 GTS indeed pays homage to the classic. Stocked with a more powerful powerplant (430 hp) and the standard Sport Chrono package, the 911 Targa GTS features GTS-specific elements such as; matt black 20-inch wheels with central wheel locks, sport design front end, black air intake screens and, also in black, GTS logos on the doors, at the rear and on the rollover protection bar.

Porsche 911 Targa 4 takes on the GTS DNA on the inside and out

At a glance, the top-end Porsche elements on the 911 Targa 4 GTS are most evident at the front, with the intake for the auxiliary middle radiator and smoked bi-xenons with PDLS.  Profile-wise, characteristic GTS attributes are the high gloss black 20-inch 911 Turbo S wheels with central locks, the sport design door mirrors and “GTS” signatures on the doors. Silver rollover protection bar in gloss black, black-accented air inlet screen and chrome tailpipes are the highlights for the rear. Finishing off the motif are the flared rear wheel arches (+22 mm) and wider rear wheel tyres (+10mm).

Despite the Porsche 911 Targa 4’s significantly extended features, the weight-to-power ratio with the 430-hp engine was improved from 3.9 kg to just 3.6 kg per horsepower compared to the S version. This lets the Targa 4 GTS reach a top speed of over 300 km/h with a PDK transmission, and the stopwatch records 4.3 seconds for the sprint from zero to 100 km/h. Although the engine produces an additional 30 hp, its combined fuel consumption, from 9.2 to 10.0 l/100 km, is deemed efficient.

Inside, the black Alcantara on the steering wheel and seats and trim accents made of black brushed aluminum create a sporty flair. Integrated at the center of the instrument panel is the stopwatch of the Sport Chrono package. In the front, the four-way adjustable Sport Plus seats,with their black GTS logo on the head restraints, provide additional lateral support and long-distance cruising comfort for driver and passenger.

Another Porsche variant taking center stage at the NAIAS is the top flight Cayenne Turbo S. The sporty SUV is primarily distinguished by its new engine charging concept with turbochargers integrated in the exhaust manifolds. The new engine charging concept increases the power of the Cayenne Turbo S to 570 hp, up 20 hp compared to the previous Turbo S. The SUV’s maximum torque also went up by 50 Nm to 800 Nm. Sprint from 0 – 100 km/h is accomplished in 4.1 seconds (0.4 s faster than predecessor), while top speed reaches 284 km/h.

Standard exterior features of the Cayenne Turbo S include air inlet surround in high gloss black at the front, LED headlights wih PDLS, undersides of door mirrors similar to body paint, roof spoiler in body color, wheel arches in body color, and 21-inch wheels in distinctive 911 Turbo design with black painted edges.

On the inside, there are full-leather interior with embossed Porsche emblems on head rests, interior carbon accents, black/creme color combo., just to name a few. A sport exhaust system is available as an option in combination with a switchable sound symposer, which optimally transmits the V8 sound experience into the interior.

The Cayenne Turbo S also underscores its position as a top athlete in its chassis systems. Its standard Porsche Composite Ceramic Brakes (PCCB) include 420 mm front brake discs and, for the first time, ten-piston calipers. The rear brakes have 370 mm discs and four-piston calipers.

In addition, the active roll stabilization system, Porsche Dynamic Chassis Control (PDCC) proactively reduces side tilt when driving through curves early on. With Porsche Torque Vectoring Plus (PTV Plus), the SUV gets improved dynamic handling and stability thanks to specific brake interventions at the right or left rear wheel.

Completing driver’s assistance aids on the Cayenne Turbo S’ package is the active hang-on all-wheel drive system, the Porsche Traction Management (PTM). PTM permanently drives the rear wheels and provides full variable power to the front wheels to ensure top-notch driving dynamics and traction at any speed.
