As he was finishing high school, Hammann heard about a racing competition on television show called
GT Academy. The show gives
PlayStation Gran Turismo video game drivers a chance to compete in a variety of scenarios on real racing tracks. Only the fastest 32 drivers on a specified course advance to the following round. He finished in the top 100 in high school then top 60 in his first year of college. At a Road America race, he met one of the previous winners of the show who was racing professionally after beginning his career as a parts delivery driver. The experience caused Hammann to see the potential of show and he began to take the competition very seriously; he studied other top competitors' lap times and frequently practiced. His mother gave him improved steering equipment as a Christmas present. Hammann raced over to obtain his best lap time and averaged nearly per day; his best time was in the fastest 20 (within the top 32 positions out of 450,000 competitors)) to advance to the next round in New York City. He took a break from college to compete 2014 show. Judges, including
Danny Sullivan, interviewed Hammann to see how well he would represent
Nissan, his fitness, and his skills. He made the top 12 and was entered in a week-long competition at Silverstone, England. Hammann won the competition. ==Racing career==
