Though it's a large luxury sedan, the 2012 Hyundai Genesis has surprisingly good fuel-economy figures with its base engine. However, it also comes in more powerful V-8 editions, and those models aren't quite as efficient.
The base Genesis 3.8 is outfitted with a 333-horsepower V-6. It's rated by the EPA at 18/28 mpg, as good as some large front-drive sedans. It's an improvement over the 2011 version by as much as 2 mpg on the highway cycle.
The 385-horsepower Genesis 4.6 earns an EPA rating of 16/25 mpg, up slightly from last year. It also benefits from the Genesis' new eight-speed automatic transmission, as does the 429-hp R-Spec sedan, which is rated at 16/25 mpg.
Unlike most other luxury vehicles, the Genesis doesn't require premium gasoline. If it's used, it yields a few more horsepower, but likely won't affect fuel economy.
NOTE: The Genesis sedan is among those Hyundai vehicles included in a restatement of fuel-economy figures. From the 2011 to the 2013 model year, the EPA has calculated that many Hyundai vehicles had overstated gas-mileage ratings that did not hold up to confirmation testing performed by the agency. Owners will receive reimbursements for extra fuel used, and can initiate payment through Hyundai's site, www.hyundaimpginfo.com.
