Aiming at the heart of the midsize market, the redesigned and incredibly competent 2006 Hyundai Sonata is available in three trim levels. The base GL model offers a 162-horsepower, four-cylinder motor mated to either a five-speed manual or optional four-speed automatic transmission. Step up to the GLS and choose from the same four-cylinder mated to a four-speed automatic or a 235-horsepower six-cylinder mated to a five-speed automatic transmission. At the top of the lineup is the LX, equipped with the V6/automatic combo and an array of standard features. Exclusive to the LX are exterior chrome trim, automatic climate control with Hyundai’s air quality system, and leather seating with matching door inserts and sliding armrests. All Sonatas are equipped with front, side, and curtain airbags, as well as stability control, and are covered by an impressive 10-year/100,000-mile powertrain warranty.
