IRVINE, Calif., February 1, 2011 – As part of Kia Motors America’s (KMA) largest marketing campaign to date, the brand is returning to the Super Bowl for the second year in a row with a new 60-second spot introducing the all-new 2011 Optima midsize sedan titled "One Epic Ride," and its "One Epic Contest," which gives consumers the opportunity to win one of five all-new 2011 Optimas. Beginning today at 3 p.m. ET, participants can view the first question and clue for the contest by logging onto, with three additional questions and clues to appear each day1 leading up to the big game on Sunday, February 6.
The first question in KMA’s "One Epic Contest" asks players "What is the estimated MPG on the highway for the all-new Kia Optima Turbo?" Gamers must use their wits and discover clues hidden within various media channels – including 15-second TV spots, print ads and social media postings – to answer the question and those that will follow this week.
"Following an extraordinary 2010, which included our first Super Bowl commercial, we knew we needed to return to the big game with an expanded campaign to match the magnitude of the head turning all-new Optima," said Michael Sprague, vice president, marketing & communications, KMA. "In addition to the ‘One Epic Ride’ commercial, we wanted to explore various ways to engage and interact with consumers, and ‘One Epic Contest’ offers the perfect platform to showcase the all-new Optima in a fun and challenging way."
Kia’s "One Epic Contest" invites consumers to embark on their own adventure through an online grid-based hieroglyphic game set in an ancient temple for an opportunity to win one of five all-new 2011 Optimas. The fifth question will be revealed the moment "One Epic Ride" airs during the Super Bowl on February 6, and the answer can be found within the spot.
Participants must correctly type the answer to each question at Upon answering all five questions correctly, a final challenging puzzle game will be revealed and the first five participants to solve the final puzzle before 11:59 p.m. ET on February 7 will win an all-new 2011 Kia Optima.
Optima Super Bowl Spot
In "One Epic Ride," people across space and time – from a police officer and an international villain to aliens and an ancient chief – will go to great lengths to snatch the all-new Optima from the clutches of others and put themselves behind the wheel. The eye-catching Optima becomes an object of desire, and even Poseidon, the king of the sea, does his best to get his hands on the car.
Airing during the first quarter of the big game and created by David&Goliath, "One Epic Ride" demonstrates the extreme measures people will go to get their hands on a midsize sedan that defies the conventions of the segment with a combination of striking design, exhilarating performance and outstanding value not found anywhere else in the category.
The all-new 2011 Optima advances Kia Motors’ design-led transformation with completely new and stunning design characteristics and its three new powertrains – including the brand’s first-ever turbo and hybrid engines (available in the coming months) in the U.S. – deliver a class leading combination of power2 and fuel economy3 while the sedan’s spacious cabin is outfitted with the latest technology features and luxury amenities.
Additional Super Bowl Program Elements
In addition to the spot and contest, Kia’s Super Bowl plan includes additional elements such as partnering with SocialVibe to create a Kia-branded social media game, providing consumers with a valuable test drive incentive and several homepage takeover ads following the game.
