The word development. They won’t be developing ICE technology any further. It seems unlikely to me that they’d stop producing ICEs altogether, but I can see why they’d focus on developing electric technologies instead.
But they're still iterating on current ICE engines, which you could call development. And in that case they're still developing ICE technology. It sounds like the only thing they're claiming is they will not come up with completely new designs.
The old product will get big fixes and some minor performance improvements (basically maintenance mode), but all the real R&D is happening on the new product.
Yeah, this was exactly my train of thought. That and the fact that it'd be a different story/title if they had completely stopped producing ICE cars, not engine development. There are emissions targets they're still on the hook for.
