Twenty-two down, two to go. The team will head to the Middle East in buoyant mood.
"We are looking forward to the penultimate race of the season in Qatar off the back of our one-two finish in Las Vegas," said Toto.
"The team did a great job across the three days in the United States. We were quick throughout and executed well on Saturday night," he added.
After a challenging run of races following the summer break, Vegas was a fitting reward for the effort put in trackside, and at Brackley and Brixworth in the past few months.
"A highlight result is exactly what we wanted at the end of the season, and it is well-deserved given the hard work and determination everyone has shown in the second half of the year."
There was high praise too for both Lewis and George, who had very different but equally impressive races.
Between them, the pair topped every session and led every lap of the Las Vegas Grand Prix weekend.
"George controlled the race from pole position, drove superbly and had pace in hand to spare," said Toto.
"Lewis meanwhile put in a stellar comeback from P10, cutting his way through the field to P2 to secure the top two steps of the podium for the team."
A triple-header though, allows little time for resting on laurels.
"The celebrations were enjoyed on Saturday night before focus quickly returned to the two Grands Prix ahead of us," said Toto.
