As anticipated, the Tribute Edition's technological foundation is the standard Stinger's GT variant. 

That indicates that it has a 3.3-liter twin-turbo V-6 engine that 

generates 368 horsepower (275 kW) and 376 pound-feet (510 N-m) of torque. 

Kia has not yet said if the Gran Turismo would be offered with optional 

all-wheel drive in addition to the basic rear-wheel drive, which already makes it 

apparent that the Stinger won't get a power upgrade as a parting present.
