Carroll will be responsible for sales outside of Russia including Azerbaijan, Armenia, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Tajikistan, Turkmenistan, Uzbekistan and Ukraine.
Carroll resigned from Chevrolet a year ago after heading GM’s reincarnated Daewoo brand since 2002 in the UK.
Carroll said: "In my career, I have been responsible for a series of start-ups, taking new ventures from concept through to maturity.
"The goal of GAZ to double the size of the business over the next five years, with international growth playing a major part, is a unique challenge in the global automotive industry. GAZ is building a very talented international senior team, and I am excited to be part of that."
