The 2020 Genesis G80 RWD makes sense for someone who wants a large rear-drive car with a turbocharged six-cylinder and automatic transmission. Plan around 20 MPG overall, with better results on highways than in city traffic. The EPA fuel-cost estimate is $4,100 per year, so fuel spending is a central part of ownership. Its 442-gram-per-mile tailpipe CO2 figure also reflects that gasoline use.
