"Cruise provides our company with a unique technology advantage that is unmatched in our industry. We intend to invest significantly to further grow the talent base and capabilities already established by the Cruise team," said Mark Reuss, GM executive vice president, in a statement.
GM has been investing heavily in autonomous driving technology, as are its rivals. It plans to launch a fleet of self-driving Chevrolet Volts at the campus of its Warren, Michigan-based technical centre late in 2016.
In early January it also spent $500 million for a large stake in ride-hailing service Lyft, with an eye to eventually having Lyft drivers use its autonomous cars.
