Prior to joining MWR in 2009, Hallam held various positions with the McLaren Formula 1 team. When he left the team, he was Head of Racing Operations. He also spent eight years working as an engineer with Team Lotus.

Hallam’s exit is the latest in a series of recent departures this summer for MWR. In May, it was announced that director of vehicle design Mike Coughlan was leaving MWR to join the Williams F1 team. As a result, MWR is suing Coughlan for breach of contract, and they are suing Williams for interference of contract. They are seeking an undisclosed sum of damages. The team also agreed to part ways with Cal Wells, their Executive Vice President of Operations, in July.

Hallam’s bio has been removed from MWR’s website, which could be an indication that his departure was not on the best of terms.

MWR executive vice president Steve Hallam is rumored to be the one who will oversee MWR’s Grand Am effort.  Hallam joined MWR before the 2009 NASCAR season, leaving his job as head of race operations for McLaren in Formula 1 where he won a World Driving Championship with Lewis Hamilton.

There has been no word on what make or model of car MWR would field, but Waltrip and Kauffman recently drove a Ferrari 458 Italia in the 24 Hours of Le Mans endurance race at Circuit de la Sarthe, Le Mans, France. The Ferrari was prepared by an Italian team, AF Corse SRL.

Rui Águas also drove with Waltrip and Kauffman. They qualified 44th out of 56 cars, and 15th in the GT Endurance Pro category. They did not finish the race, but were scored in 38th place overall and 13th in the GTE Pro category after completing 178 laps, 136 fewer than class winner Corvette Racing.
