The letters GLS occur on Hyundai vehicles and allude to the vehicle’s trim level. Trim levels refer to the many packages available, which range from the base factory model to sport and limited-edition variants. Three model levels are available for the 2014 Hyundai Elantra four-door car, for example.
Although some automotive retailers use titles like grand luxury sport and grand limited edition, the GLS Hyundai is not an official abbreviation. The Hyundai Elantra SE is the entry-level trim level. It comes with air conditioning and cruise control as standard equipment. The Limited and GLS Sport models follow, with enhancements such as a more powerful engine and sportier suspension.
