Scion's 2012 iQ city car will arrive in some U.S. showrooms this December.

Scion has announced that its Smart-rivaling iQ city car will arrive is select United States markets this December. The iQ is slated to be available at Scion dealers nationwide by March 2012.

The iQ will initially launch in the western region of the United States, which includes Alaska, Hawaii, California, Oregon, Washington, Idaho and Montana. Scion will follow up that December launch with a rollout to southern states in January 2012. The U.S.' eastern seaboard will gain access to the iQ in February, followed by the Mid-West in March.

Stretching just 10 feet in length, the U.S.-spec iQ - which is sold in Europe as a Toyota - is powered by a 1.3L four-cylinder developing 94 horsepower and 89 lb-ft of torque. Power is sent to the car's front wheels via a CVT transmission.

Although the iQ's 37mpg highway rating is no longer eye-popping, its 36mpg city rating does make for an impressive 37mpg combined rating. Toyota says that mileage can be achieved on regular gas.

When the iQ finally does arrive at a Scion dealer near you, it will carry a starting price of $15,995, including destination. While that may seem high for a car so small, the iQ does come well-equipped, with standard kit including power side mirrors, ABS and a Pioneer sound system.
