TORRANCE, Calif. (AP) -- David Wilson has been named acting president and general manager of Toyota Racing Development.
Wilson took over Thursday after Lee White stepped down earlier this week.
Wilson will be responsible for all of TRD's day-to-day operations and activities. These include engineering, manufacturing, engine build and supply chain management. Wilson also will continue in his role as senior vice president for TRD's administration, finance and facilities department.
White will officially retire at the end of the year, but remain with Toyota as a special adviser until then. TRD said he is stepping down immediately to tend to family health care needs.
The change comes as TRD is struggling with durability in its engines, and White took the blame for a quality control issue that led to an overly heavy part in Matt Kenseth's winning engine at Kansas.
