Kia and Hyundai showed off some of their new designs Wednesday ahead of the opening day of the 2012 Chicago Auto Show.

Meanwhile, GMC, Ford and Nissan used the auto show to display updated versions of some of their cars.

Here's a look at some of the highlights of the auto show.

2013 Hyundai Elantra Coupe and Touring

Hyundai is adding coupe and 5-door models to its popular Elantra, which is currently available only as a 4-door sedan.

Hyundai introduced the two new models at the 2012 Chicago Auto Show Wednesday.

Kia Track'ster Concept

Also in Chicago, Kia showed off the new 3-door Track'ster concept, which is based on the 5-door Soul.

While the concept isn't intended for production, Kia managers say it hints at potential design cues for the next Soul.

2013 GMC Acadia

GMC showed off its new 2013 Acadia SUV Wednesday at the 2012 Chicago Auto Show.

The refreshed car takes several design cues from its popular smaller sibling, the GMC Terrain. While most of the SUV carries over from the 2012 model, GMC updated the headlights, taillights and bumpers.

2013 Ford Mustang Shelby GT500 Convertible

Ford's most powerful Mustang has dropped its top. Ford showed off the convertible version of its Mustang Shelby GT500 Wednesday at the Chicago Auto Show.

The car celebrates the 20-year anniversary of the Ford Special Vehicle Team (SVT), which has focused on coaxing every bit of sport and power out of Ford cars and trucks. To mark the occasion, Ford brought a 1992 Mustang SVT Cobra to Chicago.

While the 1992 version was considered extreme with its 230-horsepower engine, the 2013 car pounds out a heavy 650 horsepower.

The GT500 convertible has the necessary transmission, brakes and suspension to handle all that power. But there's also a button on the dashboard that turns down the performance to make driving the car a little more civilized.

2013 Nissan NV200

We're used to seeing cargo vans from Ford, Chevrolet and Dodge. Now, Nissan is getting in the business and taking a smaller approach.

On Wednesday, Nissan showed of its new NV200 small commercial van at the 2012 Chicago Auto Show. Nissan already sells the larger NV commercial van, but the NV200 is significantly smaller.
