General Motors plans to completely phase out vehicles using internal combustion engines by 2035, Chairman and Chief Executive Officer Mary Barra announced Thursday. The automaker will go completely carbon neutral at all facilities worldwide by 2035.

Barra has frequently touted GM's plan for “an all-electric future,” recently increasing to 30 the number of pure battery-electric vehicles it will launch by the middle of this decade, but this marks the first time the largest Detroit automaker has set a hard target for completely phasing out gas and diesel engines for all light-duty vehicles, including pickups and SUVs.

I think Americans will like electric cars. They'll have good acceleration, with rocket-like starts onto the freeway if the drivers want to really wallop the accelerator. Battery packs are big and heavy, which necessitates larger, higher profile, longer vehicles. The demand for larger ranges and bigger battery packs might actually bring back some of the 220-inch behemoths that once ruled the road in 1950s and 1960s, especially for people who don't live in cities and have to parallel park.

It's unclear if there will be much of a push for efficiency standards with the new vehicles, especially right away, as electricity is so cheap and plentiful as gasoline once was, and the tailpipes for generating plants tends to be located outside of cities, so localized pollution is a lot less of an issue.
