GM is going to stop producing the Chevy Bolt… so it can concentrate on EV pickup.
Good: It’s better to concentrate on fewer products.
Bad: But instead of cancelling peripheral products like Hummer… they cancel their #1 selling EV.
Profit margin. GM makes a lot less on each Bolt, than they will on the pickups.
Also, GM's CAFE numbers will rise appreciably.
Once the EV Silverado / Sierra start being produced, they'll quickly be the #1 EV GM sells.
The Hummer is GM's 'halo' EV. It's purpose is to drive sales of other products, not so much to be a volume leader. Its battery tech provides the foundation for the upcoming pickups, allowing them to get real world miles on the packs, before releasing them in large scale on the pickups.
The ICE pickups will still be available for awhile. IIRC, I saw a survey recently on what people plan to choose for their next vehicle -- the majority are still going to be ICE-equipped, and the big concern is charging infrastructure / range anxiety. Not to mention all of the different industries they're used for where the vehicle can't be taken out of service midday for
x hours to recharge. That issue still needs to be resolved, compared to refueling time with gas / diesel.
Most people use their vehicles for commuting / short errands (< 50mi / day), and home chargers will easily take care of those needs. But everyone thinks they're going to drive 300 miles a day, so until there's a charger on every street corner...
