Team Penske's elder IndyCar statesman has accomplished much in his illustrious career; 2017 was his 18th and final season in the series with the same squad (although it was also his 20th in total).
And what a record they enjoyed together: three Indianapolis 500 victories – more than any other active driver – 30 wins, and four-time IndyCar Series runner-up. The 42-year-old shows no sign of slowing down, either, having just finished fourth in the 2017 standings.
The Brazilian, who became the first driver to win back-to-back Indy 500s in his first two starts at the Brickyard in 2001 and 2002, and won the "Greatest Spectacle in Racing" again in 2009, is known for his signature victory celebration of climbing the fence after taking the chequered flag. His infectious attitude, signature smile and outbursts of unbridled enthusiasm make him one of the sport’s true entertainers.
But Helio is just as quick (on his feet, at least) outside the car. In 2007 he competed in ABC's hit television show Dancing with the Stars, wowing judges and viewers alike with his perfect Quickstep, Foxtrot and Cha Cha routines to seal the Season 5 title.
Now competing in the IMSA WeatherTech SportsCar Championship with Team Penske, Castroneves will make his second ROC appearance in Riyadh after debuting 12 months ago in Miami.
