Task: Question Answering
Input (English): Passage: Cole Trickle is a young racer from Eagle Rock, California, with years of experience in open-wheel racing, winning championships in the United States Auto Club. Originally setting his sights on the Indianapolis 500, Cole realizes that "To win in Indy I'd need a great car, but stock cars are all the same". He is recruited by Chevrolet dealership tycoon Tim Daland to race for his team in the NASCAR Winston Cup Series. Daland brings former crew chief and car builder Harry Hogge out of retirement to lead Cole's pit crew. After Cole sets a fast time in a private test at Charlotte Motor Speedway, Hogge builds him a new Chevrolet Lumina.
In his first few races, Cole has difficulty adjusting to the larger NASCAR stock cars and communicating with his crew, while being intimidated on the track by Winston Cup Champion and dirty driver Rowdy Burns; these obstacles, combined with crashes and blown engines, prevent Cole from finishing the races. Discovering that Cole does not understand common NASCAR terminology, Harry puts him through rigorous training. This pays off at the Darlington race, when Cole uses a slingshot maneuver from the outside line to overtake Rowdy and win his first race.
The rivalry between Cole and Rowdy intensifies throughout the season until the Firecracker 400 in Daytona, where both drivers are seriously injured after being caught in "The Big One". Recovering in Daytona Beach, Cole develops a romantic relationship with Dr. Claire Lewicki, a neurosurgeon at Halifax Hospital. NASCAR President Big John brings Rowdy and Cole together in a meeting and warns them that he and his sport will no longer tolerate any hanky-panky from the two rivals. Persuaded by Big John, Cole and Rowdy have lunch and settle their differences by banging rental cars on the beach. The bitter rivals soon become close friends. 
Question: Who become close friends after being bitter rivals?
Output (English): Rowdy.
