General Motors Co. named a new company president Jan. 3 after the previous president took the helm of GM's self-driving car unit Cruise.

Mark Reuss will take over as GM president effectively immediately, according to a GM news release. Reuss has been executive vice president and president of GM's global product group and Cadillac since June. Reuss will maintain those roles and also assume responsibility for GM's Quality organization.

The Detroit native started with GM in 1983 as an intern and played a critical role in transitioning the company to electric and autonomous technologies over the years, GM Chairman and CEO Mary Barra said in the release.

"Mark’s global operational experience, deep product knowledge and strong leadership will serve us well as we continue to strengthen our current business, take advantage of growth opportunities and further define the future of personal mobility," Barra said.

Reuss is doubling the resources for electric- and autonomous-vehicle programs in the next two years, according to GM.

On Nov. 29, 2018, GM announced its then-president Dan Ammann would take over as the CEO for Cruise. Ammann's role change was effective Jan. 1.
