After numerous leaks and spy photos, Hyundai has officially unveiled the redesigned 2011 (2010 in Korea) Sonata.

Boasting a dramatic "fluidic sculpture" exterior, the Sonata features a four-door coupe appearance with a sweeping roofline and a compact greenhouse. Inside, the car adopts premium materials and advanced technology.

According to Hyundai's Vice Chairman, Euisun Chung, "The Sonata will set a new standard for world class mid-size sedans with state-of-the-art technology, superior build quality and emotional design."

The Korean market Sonata uses a 2.0-liter Theta II MPi petrol engine with 165 PS and 202 Nm of torque. It averages 12.8km/L (30.1 mpg or 7.8L/100km), which is an 11% improvement over today's car. In January 2010, Hyundai will offer the 2.4-liter Theta II GDI engine (it will become the standard engine for US models). As we have previously reported, a Sonata hybrid will eventually be offered. All engines will be connected to a new six-speed automatic transmission, which has been specially designed to deliver improved performance and fuel efficiency.

In terms of equipment, the Sonata boasts a three-piece panoramic sunroof, a Parking Guide System (PGS), an 8-inch LCD display and an optional JBL premium audio system

Hyundai's Korean plants will begin production shortly, while US production is scheduled to occur in early 2010.
