Spencer Bucknum aims to become the third generation of his family to race in IndyCar, following father Jeff and race-winning grandfather Ronnie, and enters United States Formula 4 this year.
Kiwi Motorsport has signed Bucknum to race in the country’s official FIA championship, following a title-winning sophomore campaign in Formula Pro USA’s West Coast-based F4 Western series in 2020.
His father Jeff came second in the LMP2 class of the American Le Mans Series as well as competing in IndyCar part-time in 2005, while Ronnie raced for Honda in Formula 1 and was the first ever winner of the Michigan race that went on to become one of IndyCar’s 500-milers.
“I’m excited to announce that I will be teaming up with Kiwi Motorsport this year for the 2021 US F4 season,” said Bucknum.
Also joining the US F4 grid is Trevor Russell, who will drive for Team Crosslink alongside Ryan Shehan and Emily Linscott, whose car will be co-run by Kiwi.
“I am excited to join the F4 grid and Team Crosslink in 2021,” said Russell.
“Crosslink is one of the premier teams in the series and that will go a long way in my progress. With both F4 and Formula Regional [Americas] programmes, there is a path to move up internally which is something that I am focused on.”
Russell has picked up single-seater experience in Formula Ford cars in regional competitions over the past two years, as well as racing in single-make sportscars series since making his first steps in car racing in 2018.
There are now 23 drivers signed up for the 2021 US F4 season.
