the Rio and Accent tie for second in fuel mileage ratings among all 2012 small cars that are non-hybrid and gasoline-powered.
USA Today
The acronym stands for "Idle Stop and Go," which is a fuel-saving system that turns off the engine when the car is stopped and seamlessly turns it on again when the brake pedal is released. This eco-smart mechanism is good for approximately one more mpg across the board, according to Kia.

The traffic-congested streets and freeways near our office did our fuel economy no favors, so the best we could manage was about 25 mpg in mixed driving conditions.
Edmunds
With direct injection on a small-displacement four-cylinder engine and lightweight bodies, the 2013 Kia Rio gets reasonably good--albeit not class-leading--fuel economy.
The 2012-2013 Kia Rio is one of a set of vehicles found to have overstated fuel-economy numbers. Kia initially submitted figures of 30/40 mpg and 33 mpg combined (34-mpg combined with the manual) to the EPA, which allows automakers to self-certify fuel economy. On a confirmation check of several vehicles, the EPA found the Rio's actual tested fuel economy to be 28/36 mpg (31 combined) with the automatic transmission or 29/37 (32 combined) with the manual transmission. The 2013 Rio Eco model was also downgraded, from an original 31/40 mpg (34 combined) to 30/36 mpg (32 combined). Owners can register with Kia to receive reimbursement for the gas consumed above and beyond expected levels; more details are found at KiaMPGInfo.com.
This year, Kia's introducing a stop/start system that shuts off the Rio's engine at longer pauses and stoplights. At first due in the 2012 model year, it's now being offered on 2013 Rios. And considering that EPA adjustment, it now adds 2 mpg to the EPA automatic-transmission city rating--at 30 mpg city, 36 highway.
Conclusion
Stop-start arrives for the 2013 model year and lifts the Rio's city fuel economy by one mile per gallon.
