In 2005 Hyundai facelifted the Tiburon and reshuffled the model lineup; offering GS, GT, and SE models. The SE was now a separate trim from the GT models. Hyundai's four-cylinder engine went into the GS, while the other two held the 2.7-liter V6. A five-speed manual transmission was standard. A four-speed automatic with a manual shift was optional for GS and GT models, but the SE had exclusive use of a six-speed manual gearbox. Anti-lock brakes was standard on the SE and optional for the GT coupe, which could be equipped with leather upholstery. GS coupes rode on 16-inch wheels, versus 17-inch for other models. All-disc brakes and front side airbags were standard. Anti-lock brakes were made standard on all 2006 model Tiburons.
