[5] The Mark X was sold as the Reiz (Chinese: 锐志; pinyin: Ruìzhì) in China, which was produced by Tianjin FAW Toyota Motor Co. Ltd.

The Mark X was also officially imported to Indonesia in limited quantities between 2012 and 2013 to replace Australian-built Camrys as premium taxis.

The continuation of describing this vehicle as the "X" series is a reference to the first dedicated Mark II platform introduced in 1972.

A first in its class is the rear bumper with an integrated exhaust outlet, which later moved to the corresponding model year Lexus LS series and the Crown.

An LED lamp for the ceiling runs from the front of the vehicle to the rear, creating a "mood" lighting system.

[16][17][18] Changes from the previous generation include the elimination of the exhaust outlet diffuser, 6-speed automatic transmission for All-Trac 4WD models and return to the hinge design boot instead of lift support.

The vehicles also gained "Toyota Safety Sense" consisting of autonomous emergency braking, lane departure alert, automatic high beams and radar cruise control as standard.

The exterior differentiates itself from other grades by arranging the mall plated grille, trim specific side skirts and unique front bumper design.

[20] Other features include a retractable rear sunshade, fully automatic self-parking system, driver's power 8-way adjustable seat and passenger 4-way power seat (with inbuilt heating and cooling) and electronically adjustable shock absorbers (Adaptive Variable Suspension System (AVS) which can be controlled from the cabin.

Unique to the Sports variant is Vehicle Dynamics Integrated Management with variable gear ratio steering which changes the ratio of steering input to wheel movement so as to help low-speed parking as well as remain stable at high speed.

[21][22] Other standard features include aluminium pedals, footrest and steering wheel paddle shifters.

The G's/GR Sport Mark X is very noticeably distinct with a 3-piece bodykit, rear boot spoiler, clear smoked taillamps, forged aluminium 19x8J wheels, four-piston calipers with 356 mm (14.0 in) front and 310 mm (12.2 in) rear ventilated brake disks, upgraded suspension, red stitching leather interior, carbon style centre console and instrument panel, upgraded Alcantara front seats, etc.

It has a specific front and rear bumper design (shared with the GR Sport variant for 2019 model), CFRP roof which reduces the weight by approximately 10 kg (22 lb), 19-inch BBS wheels, sports seats and steering wheel, and piano black interior accents with ultra suede upholstery and red contrast stitching.

Mechanical upgrades include uprated power output to 236 kW (316 hp; 321 PS) for the 2015 model, 6-speed manual transmission with Torsen limited-slip differential, sport-tuned suspension, high-performance brakes, and additional chassis reinforcements, which include 252 additional chassis spot welds for greater rigidity, coupled with specific-tuned dampers and electric power steering.

The Final Edition comes equipped with 18-inch aluminium wheels, dark chrome-plated front bumper trim, and a red and black interior finished in Alcantara and leather.
