GrandGT based on Porsche Panamera by TECHART

German tuner TECHART has done a comprehensive tuning job on the Porsche Panamera it now calls the GrandGT and the car will make its debut at the Zurich auto show in Switzerland next month.

First off is the previously seen TA 070/T1 power upgrading kit, which dials things up to 580 PS (426 kW / 572 bhp) on the 4.8 liter twin-turbo engine, up from the series' 500 PS (368 kW / 493 bhp). Torque is also increased to 830 Nm (612 lb-ft) from the standard 700 Nm (516 lb-ft). 0 to 100 km/h takes just 3.8 seconds.

But given that the tuning outfit is called TECHART, then the visuals here should be something to look at. The tuner provides a body kit made of a fibre-reinforced material which is a composite of carbon, glass-fibre-reinforced plastic and polyurethane RIM components. The kit includes a front bumper with integrated splitter ventilation intake. LED daytime running lights are also embedded in the front bumper.

A TECHART Aero carbon fibre bonnet with integrated air outlets makes the GrandGT stand out as do the side skirts and fender flares which widen the car by 21 mm at the front wheel arches and 42 mm at the rear axle.

The tuner also provides its own sport exhaust system and a choice of light-alloy wheels ranging in size from 20 to 22-inches.

Inside, the company installed a sport steering wheel, carbon fiber trim, and a premium audio system.

For added performance, the car has been outfitted with a new exhaust system which allows the V12 engine to produce approximately 660 PS (485 kW / 651 hp).

BTR-II 650 EVO by speedART

Bummed that your kids got all the Halloween candy? Do you want to treat yourself? Well look no further than speedART's BTR-II 650 EVO.

Based on the Porsche 911 Turbo (997), the BTR is sweeter than any sugar high. It features an aerodynamic body kit with a revised front bumper, new side skirts, a rear diffuser, and a modified wing for improved downforce. Additionally, the tuner installs an adjustable sport suspension and 20-inch LSC (Light Spoke Competition) wheels.

Power comes from a 3.8-liter flat-six which has been outfitted with larger turbochargers, new manifolds, and a sport exhaust. Thanks to these modifications, the engine produces 650 PS (478 kW / 641 hp) and over 900 Nm (664 lb-ft) of torque - an improvement of 150 PS (110 kW / 148 hp) and 150 Nm (110 lb-ft). Connected to an enhanced PDK transmission (which boasts eight rings per packet, instead of the usual six), the BTR accelerates from 0-200 km/h (0-124 mph) in just over nine seconds and has a top speed in excess of 335 km/h (208 mph).
