From high-school wrestler to persistent NASCAR Cup Championship contender, Kevin Harvick knows how to do it the hard way. As the #4 team head to Homestead Miami for this Sunday’s season finale, the prospect of a second career NASCAR title is on the cards. Speaking to Lee Spencer for Mobil 1 The Grid, Harvick, Childers and stand-in Crew Chief Tony Gibson explain why adversity has been a defining source of motivation for both he and the team.

In this exclusive interview for Mobil 1 The Grid, Brazil’s Felipe Massa reflects on his F1 career – from the early days at Sauber to working with Michael Schumacher at Ferrari, and his 2014 move to Williams Martini Racing. Presenting a personal account of his career highs and lows, Massa discusses the influence of Ayrton Senna, Schumacher and Sir Frank Williams, his 2008 title battle with Lewis Hamilton, his accident in 2009 and why his U-turn on retirement left him hungrier than ever before.
