Here’s a cool video previewing the latest concept car from Hyundai Motor Company, which made a surprising debut at the ongoing Moscow International Auto Show two days ago.

Hyundai’s Accent RB concept vehicle gives us the very-first sneak peek at the up-coming, next-generation Hyundai Accent sub-compact car, which is scheduled to debut in the US market early next year. The US-spec Accent is expected to offer exciting exterior styling and advanced powertrain technology.

The US-spec 2011 Hyundai Accent will be built on the same platform as Hyundai Verna (on sale in China), however, the model will feature slightly different front fascia design. Th front fascia of the US-market Accent will incorporate hexagonal signature grille, attractively designed headlights and L-shaped front fog lights.

According to Hyundai, serial mass production of the Accent RB concept car in Russia is scheduled to commence in January 2011, while sales will begin in the spring of 2011.

Hyundai also revealed during the 2010 Moscow International Auto Show that the all-new Accent will be powered by automaker’s Gamma engine lineup consisting of 1.6L or 1.4L DOHC in-line 4 cylinder gasoline engines.

The 1.6L engine generates 122 horsepower, while the 1.4L unit produces 105 horsepower. Both will be mated to a 4-speed automatic transmission or a standard 5-speed manual gearbox. The US-market Accent is also expected to be available with more potent 1.6L GDI four-cylinder engine producing 140 horsepower.
