The compact Aerio SX Sedan is available with FWD or AWD models. A standard 155-bhp 2.3L I-4 is more powerful than most other competitors. Transmissions choices include a 5-speed manual or 4-speed automatic. AWD models are only equipped with the automatic transmission. Folding rear seats enhance cargo capacity. Side-impact airbags are standard. A 6-CD, 7-speaker audio system is available. For buyers looking for an affordable compact sedan with AWD, the Aerio is one of the few choices.
