Marcos Ambrose has opened up on his decision to retire from V8 Supercars in 2015, just months after returning to the sport. The Tasmanian won championships in 2003 and 2004 before moving to the USA to chase a career in NASCAR. Starting in the truck series in 2006, Ambrose moved up to the top-level Sprint Cup series in 2009 and completed six seasons. Ambrose then made the jump back to V8 Supercars when the American group Team Penske joined forces with Dick Johnson Racing. He competed in the final round of the 2014 season and the first of 2015 before coming to the realisation it was no longer for him. "The burnout was certainly there," he told respected commentator Greg Rust during a Q&A at the CAMS awards night on Saturday.
"That's why when I came back to Australia I realised that I wasn't the right person to lead Dick Johnson/Team Penske on. I've paid my price in racing. Forty races a year plus all the other show events you do throughout the season, you supersize a whole career in one season over there. That's just a fact of life. A lot of drivers do burn out. And I just realised that I'm not the right person for that team in the phase that they're in. I need to get out of the way. And that's what I did. There are no regrets there. I'm really happy with the choice. It's just unfortunate that I let people down. That's really what bugs me today. But you've got to be the bigger man to really know when to make those hard decisions, and the hard decision was made."(Yahoo Sports)
