At the rear, there is a modified rear bumper with an integrated diffuser, a four tailpipe exhaust system, and a boot-mounted spoiler. Other styling additions include front fender vents, aggressive side skirts, and 20-inch aluminium wheels with high performance Yohokama Advan Sport tires.
Inside, the Mark X G Sports features a sports steering wheel with red stitching and faux carbon fibre accents, RECARO sport seats, faux carbon fibbers trim, and an Alpine audio system. There is limited modifications under the hood though, with the standard 3.5-litre V6 producing 318bhp and 380Nm of torque being retained, as well as the six-speed automatic transmission.
