After a long-term tie-up with Sebastien Bourdais at both Newman/Haas Racing and Dale Coyne Racing, Craig Hampson will join Arrow McLaren SP as race and R&D engineer for 2020.
Hampson, who has fulfilled a similar role in the past at Andretti Autosport, has accumulated more than 30 wins, four Indy car (Champ Car) titles and played a significant role in two Indy 500 wins with Andretti.
Hampson joins the Arrow McLaren SP team which will run Indy Lights champion Oliver Askew and ex-Red Bull driver Patricio O'Ward full time in 2020.
"I am very excited to be joining the highly capable group of talented team members that Arrow McLaren SP has already assembled," said Hampson of the move.
"There are people there who I have worked with in the past, plus others who I have previously regarded as formidable competition.
"I am eager to integrate into the projects, preparation, and momentum that they already have underway for the 2020 season.
"This will be a year of growth and learning, but I'm confident that this team has the expertise, commercial backing, access to technology, and willful ambition that makes it possible to plot a course where in due time we will regularly challenge for race wins, Indy 500 victories, and season championships."
The team's managing director Taylor Kiel added: "Recruiting someone of Craig's experience and expertise is an important step for the team as we build towards the next level of competitiveness.
"He is not only an accomplished and well-respected engineer but a strong technical leader who will be a key member of our established team."
