We don't have to wait until Wednesday for the 2012 Chicago Auto Show to open its doors to the press to see what the production versions of Acura's 2013 ILX compact sedan and RDX crossover look like as the Japanese carmaker has just released the first official photos.

As we expected, the transition from concept to production didn't bring many changes on either model, just some minor tweaks to the bumper trims and the placing of smaller and less extravagant alloy wheels.

Starting with the ILX, while based on the current Civic, Acura has made considerable efforts to differentiate the compact model from its Honda sibling, both inside and out. Acura says that the primary target customers for the ILX are "Generation Y- successful 20 and 30-somethings moving into the luxury car ranks but looking for high-value propositions in their purchases."

Next week's 2012 Chicago Auto Show will play host to the world premiere of the final production versions of Acura's all-new ILX compact sedan and the redesigned RDX crossover, both of which we're displayed in showcar form in Detroit last month.

The changes on the production models are expected to be limited to some subtle design details such as the bumpers and the alloy wheels.

The third Acura prototype to debut at the 2012 Detroit Motor Show today is the 2013 RDX crossover and just like the ILX compact sedan, there's nothing really conceptual about it as what you see here is what you'll get when the redesigned crossover model arrives in dealerships across the country in Spring 2012.

The second generation of Acura's five-passenger crossover has grown in size featuring a longer wheelbase and wider tracks that result in more passenger room, and increased cargo volume.

The styling both inside and out is intentionally more mainstream though Acura's beak-like front grille remains.

The star of Acura's lineup will be a concept version of the next generation NSX super car which in the company's own words, "represents the styling direction for the next generation of Acura's super sports car".
