Defending W Series two-time champion Jamie Chadwick kicked off her 2022 campaign with double-header wins in Miami.
The Jenner Racing charger prevailed in Saturday's action-packed season opening round and then doubled down on Sunday with a lights-to-flag clean sweep from pole.
Contrary to the previous day's dramatic event, Sunday's race unfolded without any interruptions but with plenty of battled up and down the field.
But Chadwick remained out of reach of her rivals, the Williams develop driver crossing the checkered flag three seconds ahead of runner-up Nerea Marti and Alice Powell in third.
W Series will resume its season at the Spanish Grand Prix weekend in Barcelona in two weeks.
