Antilock brakes are optional instead of standard for 2007 on sedan versions of Hyundai's smallest car. Accent comes as a 2-dr hatchback in GS and SE trim, and as a 9.2-inch-longer 4-dr sedan in GLS form. The sole engine is a 110-hp 4-cyl that teams with manual or automatic transmission. Antilock 4-wheel disc brakes are standard on SE, optional on GLS, and unavailable on GS. Front side airbags and curtain side airbags are standard on all Accents. Air conditioning is standard on GLS and SE, optional on GS. A Premium Package for GS and GLS adds power windows, heated power mirrors, and keyless entry. Those features are standard on SE. Accent lends its basic design to the Rio from Hyundai's Kia division, but differs in features, pricing, and warranty coverage.
