There's no shortage of tuned Porsches in Techart's lineup, but the company's latest offering certainly caters to customers looking for something with room for four. Behold the new Techart Panamera GrandGT, which will make its public debut at next month's Zurich Motor Show in Switzerland.
This isn't Techart's first stab at tuning a Panamera, but the new GrandGT may be the most powerful. The sedan, built upon a Panamera Turbo, is the first Techart Panamera to receive the company's new power package, which boosts output from the twin-turbocharged 4.8-liter V-8 from 500 horsepower and 516 pound-feet of torque to 571 horsepower and 612 pound-feet. That extra power, derived primarily from a new engine controller and a revised exhaust system, is enough to allow the GrandGT to sprint from 0-62 mph in 3.8 seconds -- not bad for a 4343-pound car.
In line with Techart's other Panameras, the GrandGT is treated to an exterior body kit, albeit its design is completely new. A revised front fascia incorporates three enormous lower air intakes, which are designed to channel extra air into both the intercooler and brake cooling ducts. Integrated LED lighting, installed in the outermost intakes, serve as daytime running lights, turn signals, and parking lamps. A new hood, fabricated from carbon fiber, is reportedly optimized for engine cooling, while a new rear spoiler and diffuser are designed to increase downforce. Customers can choose three different wheel designs, ranging from 20-22 inches in diameter. Such wide wheels are possible thanks in no small part to the custom front and rear fenders, which are widened by 0.8 and 1.7-inches, respectively.
Techart's upgrades aren't limited strictly to exterior and engine enhancements. Inside, the tuner allows its customers to choose custom leather trim with contrasting stitching, along with available several different types of wood accents. Rear passengers can stay entertained via a pair of custom seven-inch monitors integrated into the front seats' headrests, while the seat backs can be fitted with fold-down tables.
In the U.S., a stock Panamera Turbo carries a base price of $136,250. Techart hasn't announced pricing for the GrandGT package, but expect the conversion process to add a sizable surcharge to that price point. Look for more details to emerge on November 11, when the car formally debuts in Zurich.
