The Hyundai Sonata is a mid-size car/full-size car manufactured and marketed globally by Hyundai Motor Company. The NF Sonata was launched in August 2004 in Korea, based on a new platform created from the project NF. The company's first all-aluminum I4 engine, dubbed Theta, debuted in the new Sonata. Engine choices at launch were a 2.4L I4 rated 164 bhp (122 kW) at 5800 rpm and a 3.3L V6 rated 237 bhp (177 kW) V6. The diesel version was used as a taxicab in Singapore. Diesel versions are available in Europe and New Zealand.  The U.S. May 2005 launch of the new Sonata coincided with the production commencement at the company's first U.S. assembly plant, in Montgomery, Alabama.  Classified by the U.S. Environmental Protection Agency‎ as a large car, the fourth generation was 2 in (51 mm) longer and taller and 1 in (25 mm) wider than the previous generation. Standard features in U.S. models included anti-lock braking system/electronic stability control/traction control system as well as six airbags (driver/front passenger front and side, and side curtain).
