The 4 door 2005 Hyundai Elantra GT Sedan is a slight upgrade from the lower end GLS.  It has the same 138 hp 2.0 liter inline 4 cylinder engine, with the 4 speed automatic or 5 speed manual transmission.  And like most of the rest of the 2005 Hyundai Elantra line, the GT SEdan gets about 24/34 miles per gallon.  

Inside is where some of the difference between the GLS and the GT can be seen.  The 2005 Hyundai Elantra GT Sedan comes with air conditioning, power windows, power locks, CD player, leather seats and cruise control, all standard.  Optional is a manual or powered  sunroof.  Driver, side, passenger airbags are all standard, with ABS and traction control as options to keep everyone in vehicle safe.
