Acura said Monday it would unveil three brand-new vehicles at next month's North American International Auto Show in Detroit, an aggressive push for a brand looking to position itself at the top of the luxury-vehicle market.

Acura, the luxury vehicle division of Honda, plans to introduce an ILX concept sedan that doubles as the company's first gas-electric hybrid, an RDX SUV and the NSX concept sports car.

Acura has a steady cadence of exciting new models coming to market and it will all begin in Detroit, said Jeff Conrad, vice president and general manager of Acura sales and service, in a statement.

From the all-new Acura ILX at the gateway of the lineup to the pinnacle of performance with the Acura NSX Concept, Acura vehicles are being created for luxury customers who aspire to the highest levels of quality and value, with beautiful styling and the right balance of technology, performance and environmental responsibility.

The NSX concept, which the company touted in its release as a concept version of the next generation Acura NSX super car, will likely turn the most heads. The NSX was originally produced between 1990 and 2005, but it lost its luster with buyers by the end of its run.

But speculation ramped up for a possible revival of the concept when Robert Downey Jr., on set for filming of The Avengers, was spotted with a new Acura concept car. That marked a change from the Audi R8 Downey Jr.'s character, Tony Stark, had driven in the two Iron Man films.

Then there's the ILX concept, an all-new sports sedan that Acura will launch in the spring of 2012. It will have three powertrains, and will serve as Acura's first-ever hybrid vehicle.

The company will also reveal the prototype to the 2013 RDX, the second generation five-passenger SUV. Acura said it will include a redesign.

Acura will unveil all three at the auto show, which begins Jan. 9 in Detroit.
