G Power has evolved their Typhoon program for the BMW X6M into the Typhoon S by adding newly designed body parts, a titanium exhaust system, and an increase in performance.
The 4.4-litre V8 twin-turbo engine from under the bonnet enables the G Power BMW X6M Typhoon S to produce 725 HP (533 kW) at 6,000 rpm and 890 Nm of torque from 1,500 rpm, which basically means it can accelerate from 0 to 100 Km/h in 4.2 seconds and reach a top speed of 300 Km/h.
The Typhoon S aero package includes a new front skirt with large air intakes, a vented engine bonnet made from carbon fiber, two lateral ABS grilles, side sills add-ons, a carbon fiber diffuser and 23 inch alloys wrapped in high performance tires.
Due to a new set of sports springs the G Power BMW X6M Typhoon S is also sitting with 30 mm closer to the ground.
For the interior the tuner uses a combination of handmade lather and Alcantara upholstery, and the level of customisation ranges in accordance with the customer’s preferences. 
Pricing for the G Power BMW X6M Typhoon S starts at 6,990 Euro and reaches 13,526 Euro. Installation fees are not included.
G Power press release :
G-POWER is proud to present one of the world’s most powerful BMW X6 M models
The X6 M modified by G-POWER boasts a TYPHOON S body kit, a titanium exhaust system and an output of 725 hp. The TYPHOON S body kit, derived from the TYPHOON wide-body kit, enables an increase in cooling performance of up to 15% for the 4.4l V8 twin-turbo power unit in the BMW X6 M, paving the way for an increase of 170 hp in base output, taking it to a formidable 725 hp.
G-POWER X6 M TYPHOON S
• 725 hp / 533 KW @ 6,000 r/min (+ 170 hp / 125 kW)
• 890 Nm from 1,500 r/min (+ 210 Nm)
• Top speed > 300 km/h
• 0-100 km/h: 4.2s
• TYPHOON S aerodynamic package: starts at € 6,990.00 (net)
• G-POWER performance increase for BMW X6 M: starts at € 13,526.05 (net)

The first thing that stands out about the G-POWER X6 M TYPHOON S is the redesigned front skirt that completely replaces the original part. Designed to emulate the G-POWER TYPHOON wide-body kit, the front skirt with large air intakes delivers the characteristic aesthetic of the BMW X6 M featuring the G-POWER style. The carefully honed profile also facilitates a reduction of aerodynamic lift on the front axle. Another factor in the balanced look of the X6 TYPHOON S is the G-POWER bonnet made entirely from carbon-fibre. Equipped with a central Venturi-effect engine bay vent for cooling while in motion and two lateral ABS grilles for stationary ventilation, it ensures improved dissipation from the engine compartment of hot air generated by the two turbochargers.
The G-POWER add-ons to the standard sills provide a visual transition between the wheel arches, which are filled with forged 3-part G-POWER SILVERSTONE RS aluminium wheels measuring 11×23 and 12×23 inches (also available in 22-inch). When it comes to tyres, G-POWER sticks resolutely to 315/25 ZR 23 high-performance rubber from its development partner Michelin. They deliver optimum traction and sporty handling that is further enhanced by G-POWER sports springs and a stance lowered by 30 mm.
The package is rounded off at the back of the G-POWER BMW X6 M TYPHOON S by the diffuser made entirely of carbon fibre. It provides the perfect frame for the 4 x 125 mm tail pipes on the G-POWER titanium exhaust system, which are also made from carbon-fibre.
In keeping with the dynamic look of the BMW X6 M TYPHOON S, G-POWER also offers a suitably impressive power increase to 725 hp. Thanks to the enlarged air intakes in the front skirt and the vents in the bonnet, there is an increase in the flow of cold air to the water and oil coolers at the front of the vehicle. This improves their cooling performance by around 15% each, forming the basis for a thermally stable power increase using one the electronic optimization techniques developed by G-POWER to modify the engine mapping, including removal of the top speed limiter. On the exhaust side, a full stainless steel G-POWER system (also available in titanium) delivers the necessary reduction in exhaust gas pressure. Alongside the use of sports catalytic converters, this is largely attributable to the flow-optimised G-POWER exhaust manifold. Optimised connecting channels also run between the turbochargers and cylinder heads to minimise pressure and shock losses. The outcome is an additional 170 hp, taking the total output to a formidable 725 hp at 6,000 r/min and 890 Nm of torque as of 1,500 r/min. The maximum torque is electronically limited in order to avoid overloading the standard transmission. In combination with a reinforced transmission, a maximum torque measuring an immense 1,000 Nm can be realised.
The enormous power potential of the G-POWER modified BMW V8 twin-turbo power unit imbue the X6 M with performance levels that catapult it into the very upper echelons of its class. The sprint to 100 km/h takes just 4.2 seconds, while top speed is more than 300 km/h.
If required, G-POWER can finish the interior to individual specifications with handmade leather and Alcantara upholstery.
The TYPHOON S aerodynamic package is available starting at € 6,990.00 (net) excl. installation at G-POWER in Autenzell. Pricing for the 23-inch G-POWER SILVERSTONE RS wheel set with MICHELIN tyres is € 8,865.55 (net) and the G-POWER power increase to 725 hp incl. full stainless steel exhaust system and modified connection to the turbochargers starts at € 13,526.05 (net) excl. installation (titanium exhaust system optional).
