A 2.0-liter, 138 hp inline 4 cylinder engine comes standard in all trims of the 2006 Hyundai Elantra line. Standard across the board as well are the two engine options: a 5 speed manual or a 4 speed automatic. Gas mileage for the 2006 Hyundai Elantra is a respectable 24/34 mpg city/highway. Not a large car by any standard, the 2006 Elantra has plenty of space, power and zip for regular day to day driving, though families might want to steer clear.

A new trim was added for the third year in a row to the Hyundai Elantra line in 2006: the Limited Sedan, which offers a level of luxury not previously found in the Hyundai Elantra line. Depending on the trim, there are a number of standard and optional features on the 2006 Hyundai Elantra. Air conditioning, cruise control, a leather steering wheel cover, leather seats, a CD player (which now comes standard on all trims), and now even a powered or manual sunroof are all available. For safety, the 2006 Hyundai Elantra has driver, passenger and side airbags, ABS, traction control, and power windows and locks.

With a very few exceptions, the gas mileage on the 2006 Hyundai Elantra was the feature most talked about by owners in reviews. Consistently people were getting 33-35 miles per gallon, even with the air conditioning on. Other features people love were the peppiness of the engine, even with the gas mileage, and the amount of space that is available in a compact sedan. And of course, the unbeatable warrenty. There were some minor complaints, but most of them cosmetic, like dissatisfaction with the shape of the grill or there not being a remote trunk opener. Other than that, however, most of the problems that Hyundai had with previous Elantras seem to have been fixed in the 2006. A HIGHLY recommended vehicle.
