Techart's GTstreet R also boasts a carbon fiber bodykit with active components in the front spoiler and two-tiered rear wing.

People who drive either revision of the 991-generation 911 Turbo already have one of the most potent performance vehicles on the road, but if the coupe’s already ample power ever leaves them yearning for more then Techart’s GTstreet R should definitely help. The package not only offers several levels of power upgrades, but the wind-tunnel-refined active aero body kit should keep the aggressive looking car well planted.

Techart’s body kit uses carbon fiber parts as replacements for the front and rear bumpers, slotted front fenders, side skirts, and engine cover. By aftermarket standards, the pieces actually look quite subdued, especially if you imagine the whole car in a single color. It’s not that far off from the huge intakes and big wing from Porsche’s own GT2 RS, which is currently under development.

Techart’s components serve a function in addition to looking good. The lip in the front spoiler actively adjusts airflow into the radiators. The two-tiered rear wing also raises and tilts up to 15 degrees in Performance mode for additional downforce. The company claims the whole package of parts produce 708 pounds of downforce at 186 miles per hour.

If someone adds the aggressive body kit, the buyer probably wants extra power to go with it, and Techart is ready. The firm can tune the 991.1 and 991.2 911 Turbo with packages that take the output to 632 horsepower (471 kilowatts). Customers who are patient can wait until early next year when the firm introduces an even more powerful package that boosts the mill to 711 hp (530 kW) and 679 pound-feet (920 Newton-meters) of torque.

The turbocharged flat six should sound fantastic with Techart’s custom exhaust, too. Its continuously variable pneumatic valve can constantly adjust back pressure depending on engine load. The part is like a little symphony conductor in your vehicle that always makes the engine sound the best way possible.

Techart doesn't say what these upgrades cost, but they can't be inexpensive. We would be very curious to see how the tuner's package would perform against the upcoming GT2 RS. Rumors suggest the Porsche could make 700 hp (522 kW), which isn't too far away from what Techart gets from the GTstreet R. It would be quite a race.

The new TECHART GTstreet R.
Leonberg, November 3rd, 2016

Design: distinctive. Performance: overwhelming. Appearance: unforgettable.

The new TECHART GTstreet R will thrill you. Every second. On the racetracks of the world, or in the
streets of metropolitan hotspots – the GTstreet R occupies center stage. Like its legendary
predecessors, the new GTstreet R is representing the ideal symbiosis of outstanding performance and
unrestricted suitability for daily use. Based on the Porsche 911 Turbo and 911 Turbo S (991),
TECHART has built a sportscar that sets new standards. Again.

Exterior design and aerodynamics:
The expressive, lightweight carbon fiber body parts put the 911 Turbo in the spotlight. At the same time,
the aerokit optimizes the road handling of the GTstreet R by increased downforce. Active aerodynamics
provide a total downforce of 321 kg at 300 km/h in Performance Mode. This enables breathtaking lateral
acceleration and driving stability at all speeds.

The carbon fiber GTstreet R front apron with its active front spoiler lip optimizes the airflow onto the
water- and oil coolers with additional air intakes. A central air outlet helps to reduce the aerodynamic lift.
The integrated front lights are tastefully surrounded by carbon airframes. Laterally positioned flaps
increase the downforce and reduce the drag coefficient at the same time. The lightweight carbon front
lid, which bears a three dimensional TECHART logotype at its inside, underlines the vigorous
appearance of the TECHART GTstreet R with its dynamic shape.

The carbon front fenders feature front wheel arch air outlets. Both, the heat generated by the brakes as
well as the overpressure produced by the turning wheels are discharged through racy visible carbon
slats. The carbon side skirts continue the GTstreet R design line and interlink the extended wheel
arches at front and rear aesthetically. For maximum airflow to the intercoolers, the rear side sections of
the GTstreet R feature powerful carbon air intakes.

The rear apron incorporates distinctive air outlet ducts – typical for the TECHART GTstreet styling. A
trim panel made of visible carbon fiber creates visual impact by connecting the three dimensional
taillights. A carbon rear diffusor frames another GTstreet R highlight: the high performance sport
exhaust system. Four central carbon fiber tailpipes release the exhaust fumes while generating an
extraordinary and powerful soundscape.

On top of the engine lid, the active GTstreet R rear wing catches the eye with its contoured carbon wing
profile, carbon side panels and two aerodynamic carbon fiber winglets. In Performance Mode, the
GTstreet R wing is raised automatically and its angle is adjusted by up to 15 degrees. A large
aerodynamically shaped carbon air intake unit ensures sufficient air supply for the engine at any time.

Driving dynamics & performance:
To provide the required grip, TECHART fits enlarged tire dimensions to the GTstreet R. The road
contact is ensured by 265/35 ZR 20 tires at the front (also available: 265/30 ZR 21) and 325/30 ZR 20
tires at the rear (optional: 325/25 ZR 21). Customers can chose among 20-inch or 21-inch wheels. The
forged 20-inch TECHART Formula IV Race centerlock wheels are equipped with roadlegal UHP tires.
The 21-inch TECHART Formula IV wheels feature a weight optimized rim construction and are
equipped with road tires. Both wheels can be individually customized in color and surface finish.

TECHART provides different options for the chassis such as the TECHART VarioPlus coilover
suspension with PDDC connectivity or the TECHART Noselift front axle lift system. TECHART Noselift
makes common obstacles like parking garages, ramps or speed humps a thing of the past as it instantly
provides 60 mm of additional ground clearance at the front axle at the push of a button. Individualization
of the brake calipers is quality-made with a temperature-resistant coating and ensures a perfect color

Needless to say that the new TECHART GTstreet R demonstrates its performance skills not only in
terms of its visual appearance but also when it hits the road. TECHART boosts the performance of the
engines of the 991/I and 991/II 911 Turbo and Turbo S models with a range of impressive powerkits,
which generate a total power output of up to 471 kW (640 hp) and a maximum torque of 880 Nm. In addition
a second stage of powerkits, unleashing a total of 530 kW (720 hp) will be available as of early 2017.

In combination with the 911 Turbos’ active all-wheel drive system, the driving performance of the
GTstreet R reaches a new level.

Besides its stunning sound and appearance, the new TECHART high performance sport exhaust
system features another highlight. TECHART introduces a continuously variable pneumatic valve
control as a novelty in the new GTstreet R. The stepless valve adjustment optimizes the exhaust back
pressure depending on different load conditions and avoids unwanted frequencies effectively.

Interior design:

Entering the new GTstreet R, the whole know-how and workmanship of TECHART’s interior
manufactury reveals. TECHART created two different GTstreet R interior variants. The interior package
»Exclusive« flatters with finest leather, the »Clubsport« version sets sport-focused Alcantara highlights.
Among a wide range of refinement options included in both interior packages, the »Clubsport« interior
includes a color-matched roll bar, 6 point harnesses and door opening loops.

Both interior versions come with door panel inserts and seats with GTstreet R design stitching.
Dashboard, center console, roof liner, sun visors and door pillars are covered in leather or Alcantara.
The mode switch at the steering wheel, the air vents, the air vent adjusters, the PDK gear selector, the
gear lever surround and the seat adjustment are lacquered in custom color. As an option, TECHART
carbon fiber interior parts complete the tailormade surrounding, such as trims, panels or seat
backpanels in different visible carbon fiber finishes, to mention a few.

Settled in the sport or in the sport bucket seats, the ergonomic TECHART sport steering wheel awaits
the driver. Coming with a smaller diameter, a straight-ahead marker, paddle back-covers as well as fully
individualized in terms of colors and materials, no wishes remain unfulfilled. Color-matched instrument
dials, door entry guards and aluminium sport pedals round off the unique interior design. As a sign of
exclusiveness and originality, the glove compartment features a milled GTstreet R signet with a
sequential number on its lid, and, inside the glove compartment, an exclusive handmade GTstreet R
wallet contains the vehicle documents.
