Hyundai is introducing its latest challenger, the 2011 Hyundai Sonata, into what is arguably the most fiercely contested segment in the U.S. market – that of the family sedan. The sixth-generation Sonata, which goes into production in mid-December before going on sale early in 2010 as a 2011 model. The new shape of the car looks more inspired by the Mercedes-Benz CLS and Volkswagen CC than any Camry. Hyundai designers have adopted the increasingly popular coupe-like sedan profile with a low, sweeping roof-line that blends neatly into a short rear deck.

The 2011 Sonata will come in three trim levels: GLS, Limited and SE, with the latter being targeted as the sport-minded model. Only the Limited and SE get the chrome grille. The GLS will receive the same design, albeit painted body color. Speaking of paint, Hyundai has been doing some notable work on colors for this important new model. At launch, the new Sonata will only be available with one engine, a 2.4-liter direct injected four-cylinder that yields 198 horsepower and 184 pound-feet.

At this point, Hyundai doesn’t acknowledge any plans to put a V6 in the new Sonata. Nonetheless, there appears to be plenty of room in the engine compartment to accommodate one. There will however be one additional powertrain option later in 2010. The Sonata will be the first U.S. market Hyundai to get the company’s new hybrid system.
