The GT4 was unveiled on May 29, 2023 and is similar to a XT4, but has different dimensions including a slightly longer wheelbase and has sleeker styling and a lower roofline.

Its interior features a 33-inch instrument cluster and center infotainment combination display, heated and ventilated seats, a 15-speaker AKG audio system, surround-view camera system, digital rearview mirror, and a color heads-up display.

The 1.5-liter turbocharged engine produces 208 horsepower (155 kW; 211 PS) and 199 lb⋅ft (270 N⋅m) of torque, while the 2.0-liter turbocharged engine produces 233 horsepower (174 kW; 236 PS) and 258 lb⋅ft (350 N⋅m) of torque.

Both engines operate with a 48-volt mild hybrid system and drive the wheels through a nine-speed automatic transmission.
