TechArt builds 720 hp Porsche 911 (991) Turbo as a cabriolet

Article by Christian A., on March 24, 2017

TechArt’s latest project, the Porsche 911 Turbo itself, is a pretty awesome car to own. And it’s not only because of its powerful engine, and beautiful exterior design. However, some people just can’t get enough of what is already in the market. What do I mean by that? The German automobile tuner came up with an even more extravagant design, sans roof, calling this version the GTstreet R Cabriolet.

Some of the highlights of this car in terms of performance are its powerful engine with the capacity to deliver 720 horsepower (or 530 kilowatts) and 678 pound feet torque, allowing it to accelerate from zero to 100 kilometers per hour in a mind-blowing 3.5 seconds, while proceeding to its maximum speed of 340 kilometers per hour (211 mph) -- that is even faster than a 911 Turbo.

The wonders of this car don’t end there. It has an adjustable rear wing just like the one on a GT2 RS that can tilt up to 15 degrees for an added downforce, allowing the car to travel faster. In fact, this model has the ability to produce 707 pounds (321 kilograms) of downforce at 186 miles per hour (300 mph) - this was proven when it was tested in a wind tunnel. These are made possible by its new aerokit that features an active spoiler lip, carbon front fenders, and carbon side skirts.

Its dashboard, roof liner, sun visors and center console are all finished with Alcantara, whereas the gear knob, gear lever surround, the seat adjustments, and air vents can be in any colour the customer wants it - so that it matches the rest of the car.

The same can be done to the cabin, which can be heavily customized to suit the customer’s preference. It can also be a combination of both Alcantara and leather, for a more luxurious feel. There is also a carbon fiber option for the trim, panels, and sport seat panels.

GTstreet R Cabriolet also comes with a set of 20 or 21 inch forged centerlock wheels. TechArt offers several exterior styling options. We’d like to point out a custom titanium exhaust system that is perfect when paired with Porsche’s signature flat six.

With the help of TechArt, this model gets a nose lift feature. With just the push of a button, there will be an additional 2.4 inch ground clearance at the front axle, which will be helpful when driving over humps and parking in garages.

Porsche has not announced the price for this model yet. However, with the 911 Turbo priced at $171,500 for the entry-level unit, we’ll expect at least a couple of thousands more for this variant.

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 match. Needless to say that the new TECHART GTstreet R Cabriolet 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 530 kW (720 hp) and a maximum torque of 920 Nm.

In combination with the 911 Turbos’ active all-wheel drive system, the driving performance of the GTstreet R Cabriolet reaches a new level. Besides its stunning sound and appearance, the new TECHART high performance sport exhaust system features another highlight.

Settled in the sport or in the sport bucket seats, the ergonomic TECHART sport steering wheel awaits the driver.
