The 105th Indianapolis 500 takes place on Sunday night (BST) as IndyCar’s exciting new generation of stars take on the established old guard in what is set to be a classic edition of America’s greatest motor race. Here’s Autocar’s lowdown on who to watch out for and the points of history that are poised to be written.

New versus old on the front row

Five races down in 2021, five different IndyCar winners – four of whom are under 24 years old, and three of whom are first-time victors. Now the trio that make up the front row of the grid for the race that matters more than any other in US open-wheel racing perfectly encapsulates that delicious premise of new talent versus old.

Six-time champion and 2008 Indy 500 winner Scott Dixon starts from pole position, the 40-year-old having pipped 21-year-old Colton Herta by just 0.030mph for a four-lap average around the 2.5-mile four-corner oval of 231.685mph. The driver who starts on pole has won the 500 five times in the past 20 years and Dixon, who currently leads the points standings too, is simply one of the finest IndyCar drivers in history. He is always tough to beat.

But Herta and fellow front-row starter Rinus VeeKay, 20, will both fancy their chances. The pair are among IndyCar’s youthful race winners this year, VeeKay scoring his breakthrough victory on the Indianapolis road course earlier this month. If Herta, VeeKay or 22-year-old Alex Palou prevail they will break Troy Ruttman’s youngest-ever 500 winner record that dates all the way back to 1952. Palou starts on the second row.
