Last year, the Kia Soul gained more fuel-efficient powertrains, and it can now be said that the Soul gets gas mileage that's just as good as most compact or subcompact sedans or hatchbacks.
Also for 2013, the Soul is now available with the Idle Stop & Go (ISG) technology that had originally been planned for the 2012 model year. ISG smartly shuts the engine down when it would otherwise be needlessly idling (at a stoplight, for instance), and automatically restarts it when you lift off the brake. The feature will be included as part of an Eco Package.
City gas mileage is good in the 2013 Kia Soul, although highway fuel economy is less of a delight.
Kia initially submitted figures of 27/35 mpg and 30 mpg combined (or 26/34/29 for the larger 2.0-liter engine) to the EPA, which allows automakers to self-certify fuel economy. But on a confirmation check of several vehicles, the EPA found the Soul's actual tested fuel economy to be 25 mpg city, 30 highway with the 1.6-liter engine, or 23/28 (25 combined) with the 2.0-liter engine and automatic transmission or 24/29 mpg with the manual transmission. 2013 Kia Soul Eco models, which earned 29/36-mpg and 27/35-mpg ratings have been downgraded to 26/31 and 24/29, respectively. Owners can register with Kia to receive reimbursement for the gas consumed above and beyond expected levels; more details are found at KiaMPGInfo.com
