Finnish brothers Rasmus Markkanen and Roope Markkanen have been named as the latest additions to the 2016 SMP F4 field.
Both making their single-seater debut at the age of 18, they spent the last three years competing in international Rotax championships.
Roope went on to take third in last year’s Rotax Euro Max Challenge DD2 with Rasmus finishing fifth in the same series.
The latter achieved the same position in the Rotax Grand Finals as well.
The duo joins fellow Finn karting graduates Tuomas Tujula and Juho Valtanen in the field.
