Ironically, increased demand can prove to be quite a problem for car manufacturers. Kia knows this well: despite posting a 37 percent increase in sales last year, it reckons it could have done even better if only it had the capacity to produce more vehicles.

Its all-new Optima mid-size sedan has proved to be a big hit in the U.S. in its first year, tripling its sales compared to 2010 to 84,590 units.

Along with the snazzy Track'ster concept study, Kia also revealed a new range-topping version of its Optima sedan called the SX Limited at the 2012 Chicago Auto Show.

The SX Limited, which as you may recall was teased through Kia's Super Bowl XLVI commercial this past Sunday, is based on the 274-horsepower turbocharged Optima SX adding a little bling to the mix with new 18-inch chromed alloy wheels, a chrome-accented rear spoiler, LED daytime running lights and red front-brake calipers.

Only a few days left for the big game, so Kia released the full version of its 2012 Super Bowl ad titled "Drive the Dream" for the new Optima Limited Edition featuring a slew of stars including Victoria's Secret super model Angel Adriana Lima, the Motley Crew, martial arts champ Chuck Liddell and bull rider Judd Leffew.

Out of all those stars, we all know who will capture the attention of most viewers.

Kia's marketing division came to the same conclusion as us and so it created a five-hour long looped version of the hot Brazilian model repeatedly waving her chequered flag. You can watch both videos after the jump.

With the Super Bowl XLVI match-up between the New England Patriots and New York Giants just a couple of weeks away, automakers are preparing the public for their new ads that will air during the big football game on February 5.

At last year's game, Kia took on the time traveling theme to show off its new Optima sedan. For this year's commercial, the South Korean automaker has chosen the topic of dreams to introduce the new 2012 Optima Limited edition.

The Kia Rondo minivan and Optima sedan are included in a new recall over a faulty airbag in the United States.

The National Highway Traffic Safety Administration [NHTSA] said that the recall involves 145,755 vehicles and affects certain 2006-2008MY Optima sedans manufactured from September 29, 2005, through January 29, 2008, and 2007-2008MY Rondo minivans built from September 13, 2006, through March 21, 2008.

Looking to further associate itself with the world of motorsports after the first two motorsports championships in company's history in the 2011 Continental Tire Sports Car Challenge (CTSSC), Kia today unveiled two more track-ready models at the 2011 SEMA Show, the 2012 Rio 5-door B-Spec racecar and the Optima Hybrid pace car.

Developed in partnership with Kinetic Motorsports, the new Rio 5-door B-Spec racer will compete in the newly established showroom stock racing class against various subcompact rivals such as the Mazda2, Honda Fit and Ford Fiesta starting from 2012.

It's all about fun and games when it comes to Kia's 2011 SEMA Show displays as the Korean manufacturer has arrived in Las Vegas with a roster of six sports-themed vehicles.

These include the Surfboard Rio and Hockey Forte hatchbacks that we showed you earlier today, plus the golf-themed Soul, Rio 5-Door B-Spec Racer, USTCC Optima Hybrid Pace Car and the “Slam Dunk” Blake Griffin Optima Hybrid featured here.

Los Angeles Clippers forward and 2010-11 NBA Rookie of the Year Blake Griffin made headlines at February's NBA Slam Dunk Contest when he leaped over a parked Kia Optima and performed an impressive slam-dunk after an alley-oop pass through the car's open sunroof from Baron Davis.

Apparently, Kia was equally impressed as the South Korean automaker signed up the 22-year old player for a new commercial staring – what else- the latest Optima sedan.

Kia walked away with no less than four awards from the inaugural Automotive Brand Contest organized by the German Design Council. The most important was that of “Best of Best” for overall brand design, acknowledging Kia’s new styling language.

The other three awards were won in the Exterior category by the latest Sportage, the Optima sedan and the new Rio.

Kia has issued a recall on 70,115 Optima sedans manufactured from September 29, 2005, through June 13, 2007 because of a problem related to the transmission that can cause the cars to roll even while they are in park. The company said that in some cars, the transmission shift cable may have been installed incorrectly and can become detached from the shifter. If that occurs, the car would stay in the last used gear before detachment, even if the driver moves the shift lever to the park position. Read more »

This year's Super Bowl is just around the corner and automakers are getting ready to spend millions of dollars to draw the attention of buyers. For a second year in a row, Kia will be present at the event with a full marketing campaign incorporating TV, digital, print and social media as well as in-dealership components, all focusing on the 2011 Optima midsize sedan.
