Wearing the same body kit (€6,990.00) as the Typhoon S X5 M, the X6 M has an aggressive front fascia, a ventilated hood, a carbon fiber rear diffuser, and sport springs which lower the ride height by 30mm (1.2 inches). Additionally, customers can order 23-inch Silverstone RS alloy wheels with Michelin performance tires (€8,865.55). Under the hood, the twin-turbo 4.4-liter V8 has been equipped with a remapped ECU, a stainless steel sport exhaust system, exhaust manifords and new connection pipes between the turbochargers and the cylinder heads (€13,526.05). Thanks to these modifications, output raises to 725 PS (533 kW / 715 hp) and 890 Nm (656 lb-ft) of torque - an increase of 170 PS (125 kW / 168 hp) and 210 Nm (155 lb-ft). This enables the crossover to run from 0-100 km/h in 4.2 seconds and hit a top speed in excess of 300 km/h (186 mph).

Following on the heels of their rendition of the X5 M, deluxe Swiss tuner Mansory has a package for the X6 M to woo the BMW fans.
First comes the aerodynamic/optics tuning which features a new front spoiler with bigger air intakes, a lightweight carbon-fiber bonnet with vents to improve air flow to the engine, a new rear skirt and rear diffuser, a rear spoiler lip and a roof spoiler. The wide-body wings add some girth to the X6 M - 70 mm at the front wheel arches and 80 mm at the back.
ECU-remapping and performance tuning also compliments the optical changes, which includes a power upgrade to 670 PS (493 kW) and a huge jump in torque to 950 Nm (same as on the Mansory X5 M) - up from the series' 555 PS (408 kW) and 680 Nm. It's the stainless-steel sport exhaust system with the quad-pipes integrated into the rear diffuser along with a new exhaust manifold that helps optimize that considerable power boost.
The 0 to 100 km/h sprint comes in 4.2 seconds (series: 4.7 seconds) and top speed on the electronic limiter is raised to 300 km/h (186 mph).
The Mansory X6 M also comes with light-alloy 23-inch rims fitted with 315/25R23 tires.
A sport suspension kit is added too with the ability to lower the X6 M up to 40 mm.
For the interior finish, Mansory offers a sport steering wheel and a host of bespoke options for the customer to choose from including a choice of a leather or Alcantara finish with wood, carbon or aluminium trim.
