Leandro Juncos has been confirmed as Hillspeed’s second GB4 Championship signing for the coming 2025 season, following a successful test at Donington Park last week.

The 19-year-old American driver with Argentine heritage, who was born in Miami but now resides in Indiana, had originally looked to contest the sister GB3 Championship this year but has reassessed his plans and will now partner Daniel Guinchard in Hillspeed’s GB4 line-up.

Juncos arrives in British motorsport with only a small amount of competitive single-seater experience, having raced a part-season in the USF Junior Championship last year – taking a best of fourth place at Barber Motorsports Park in Alabama.

Out of the cockpit, he has gained a key understanding on the engineering side of single-seaters in the world of IndyCar racing with the Juncos Hollinger Racing team, co-owned by his father Ricardo, where Juncos Jnr worked as assistant race strategist for American star Conor Daly last year. 

Determined to continue his family’s legacy within motorsport, Juncos aims to make strong progression throughout the year with Derbyshire team Hillspeed, which makes its eagerly awaited return to GB4 this season after a couple of years focusing exclusively on GB3. When Hillspeed last competed in the series in 2022, the squad concluded the campaign as Vice-Champions in the GB4 Team Championship.
