TrueDelta Reviews the Real Gas Mileage of the 2015 Hyundai Genesis

2015 Hyundai Genesis Real Gas Mileage: Cons
YearComment
While competitors have been switching to relatively small turbocharged engines, the Genesis continues to rely on larger normally aspirated ones. Even the base car's 3.8-liter V6 is nearly twice the size of the Audi's turbocharged 2.0-liter four-cylinder engine. Also, Hyundai doesn't yet offer automatic stop/start. The most significant impact: the Genesis gets much worse fuel economy. With two-wheel drive, the A6 2.0T scored 24 mpg city, 35 mpg highway in the EPA's tests, the Genesis 3.8 only 18/29. Add all-wheel drive, and the Audi's ratings fall to 22/32, the Hyundai's to 16/25, not good. Hyundai has developed a new turbocharged 3.3-liter V6 to replace the 3.8, but it isn't clear how soon this new, more efficient and more powerful engine will be available in the Genesis G80. It won't be available when the car arrives this summer, so most likely the 2018 model year. According to the trip computer, my real-world fuel economy was well above the EPA figures. Only when I drove the Genesis fairly aggressively did the trip computer average fall below 20 mpg. On my usual suburban route it averaged around 23 mpg, and on a 70-mph highway it averaged about 30 mpg. The former was still a few mpg short of the Audi, but the latter was at least as good. If the trip computer is accurate, the fuel economy of the Genesis isn't nearly as dismal as the EPA ratings indicate. see full Hyundai Genesis review
