Despite swapping its old and less powerful turbo 2.0-liter I-4 for a newer and bigger turbocharged 2.5-liter four-pot with 300 hp and 311 lb-ft of torque, the updated rear-drive 2022 Stinger four-cylinder now returns 22 mpg in the city, 35 on the highway, and 25 combined, according to the Environmental Protection Agency (EPA). The outgoing I-4, meanwhile, couldn’t crack 30 mpg on the highway, plus it only packed 255 horses in its stable—45 less than the 2022’s 2.5-liter unit.
Opt for all-wheel drive, and the 2022 Stinger 2.5T’s fuel economy numbers fall to 21/29/24. Predictably, the 368-hp twin-turbo V-6 of the Kia Stinger GT models still sips fuel at a far faster rate than its four-cylinder counterpart, with the EPA rating the rear-drive Stinger GT at 18/25/20 mpg and the AWD model at 17/24/20 mpg.
If outright power is what you’re after, then nab the six-cylinder Stinger GT. However, if you’re looking for a fine combination of speed and efficiency, then you might be better served by the cheaper four-cylinder Stinger.
