Will Hoskins was fastest in practice for the United States V-Prix with a scorching lap time over half a second quicker than anyone else. Championship rivals Olen Inman and Adrien Simon were next up, split by just half a tenth in the Monegasque's favour.
Carson Davenport backed up FUN's pace with fourth fastest ahead of local hero Stuart Harrison and his team mate Johan Halvosen, the Meteor pair split by Elroy Wagner's Franklin - the German with a spring in his step following the announcement earlier this morning of his move to Lopez for 2017.
Tumo Kinnumen put in a strong lap for eighth fastest ahead of equally impressive laps from the AMR drivers of Felix Beyer and Jarod Lindsey - standing in for Lewis Ellington during the session - to get both of the Australian teams cars into the top ten.

The other was Kiara Thunder, whose Holmqvist suffered a hydraulics failure while Aleksy Nowosinki was the fastest driver of the new teams.
