GM today announced a strategy to eventually deliver a zero emission product line across all its segments, though it didn’t put a specific timeline on when it would achieve that goal. The process is complex, said Mark Reuss, EVP Global Product Development, and GM doesn’t see there being “one year where we flip a switch and it’s all electric.”

Still, GM is committing to rolling out two new all-electric vehicles within the next 18 months, and to having at least 20 new all-electric vehicles in the market by 2023. GM also debuted its new SURUS fuel-cell concept platform today, which is a four-wheel steering concept truck-based vehicle with two electric motors and a flexible design which could work with a range of different vehicles in commercial capacities, including delivery vehicles, trucks or ambulances.
