The Japanese automaker Toyota unveiled the Mark X G Sports Concept at the 2010 Tokyo Auto Salon. Like all the other creations in the G-Series lineup, the highly modified Mark X comes complete with a sport tuned suspension, aggressive looking aero parts and a racing inspired interior. The exterior of the tuned Mark X is dressed up with a few trick items like a new vented hood, big mouth front bumper with strips of LEDs and intricate air ducting, IS-F style vented front fenders with matching elements in the back bumper along with an integrated rear diffuser that frames the true dual exhaust as well as a carbon fiber roof panel up top and a set of 20 inch Work alloys wrapped in sticky Yohokama Advan rubber housing a ridiculously over sized big brake kit.

The interior of the Mark X G Sports Concept is all business. The driver straps into a Recaro racing bucket and grabs hold of a leather wrapped multifunction steering wheel with red accent stitching and a few well placed Alcantara inserts. The gauges are bright and easy to read, while the center stack is dominated by a large LCD multifunction display and is surrounded by quite a bit of carbon fiber. The floor mats carry the red accent theme while a set of aluminum racing pedals put the driver in direct contact with the controls. The G Sports Concept is powered by a 3.5 Liter V6 developing a total of 313 HP and 280 lb-ft of torque coupled to a paddle shifted six speed automatic transmission sending power straight to the rear wheels.
