She takes over from Bernard Bradley who became general manager for Honda (UK) cars early last month.
Kennedy currently works as northern regional operations manager.
Bradley said: “Kennedy brings a wealth of experience from both a dealer and manufacturer perspective.
“She played an integral role in Honda’s sales success during the first half of this year and in her new position will ensure this success is continued through the remainder of 2007 and beyond.”
Kennedy will report directly to Bradley. She joined Honda (UK) in April 2005 as business operations manager, having previously worked for Reg Vardy as franchise operations manager and prior to that as an area operations manager with Renault.
