There are a few different trim levels sold under the 2012 Hyundai Accent badge, and even a choice of manual or automatic transmissions. But still, all Accents this year are rated at the same gas mileage.
The 2012 Accent checks in at 28/37 mpg, no matter which transmission is chosen. Compared to other subcompacts and compacts, it's still impressive. The highest mileage the Ford Fiesta manages is 28/37 mpg without options; add on the SFE package and it nudges 40 mpg. The Chevrolet Cruze tops out at 40 mpg highway, if you order the special high-economy version. The Honda Fit? It's far off the mark at 33 mpg highway.
We've found that the automatic Accent's in-town performance is helped along significantly by shifting into sport mode, which seems to improve off-the-line response. That's sure to take a bite off gas mileage. The manual-transmission Accent has an "eco" shift light to help train you to use less fuel, though, while the automatic has an ActiveEco button that triggers early upshifts to improve gas mileage.
NOTE: In November 2012, the 2012-2013 Hyundai was found to have misstated fuel-economy figures for the Accent. The initial 30/40-mpg, self-certified rating was checked by the EPA and found to be 28/37 mpg instead. Owners can register with Hyundai to receive reimbursement for the gas consumed above and beyond expected levels; more details are found at HyundaiMPGInfo.com.
