I don't think so. The design and production of a traditional ICE automobile largely involves mechanical engineering expertise. There is some electrical engineering discipline required for engine control systems, but these are just implementing mechanical engineering algorithms to make an ICE engine work. Also, let's not forget that many parts of these systems are outsourced to companies like Bosche. The electrical engineering required to design the 12V (or48V) systems is, in all reality, trivial these days. As far as software goes, BMW must have a few developers to develop their infotainment and implement any in-house mechanical engineering control requirements, but this is small stuff in the grand scheme of things.
Now let's look at Tesla. I believe the engineering talent requirements are much more balanced than at BMW. Electric motors have been around forever, and their design is not dramatically different than those from decades past. Improvements in design and efficiency require expertise in EM Fields, control systems, computer design, software. Mechanical engineer requirements mainly include: heat transfer, packaging, anything related to moving parts. The majority of everything in a Tesla drivetrain is the result of electrical engineering and software expertise, which they've developed over the last decade. They have built a platform that is highly customizable after production. You want an improvement to an existing vehicle? Change the software controls to alter electron movement.
The point of all my rambling is that I don't think BMW or any other legacy manufacturers have the talent pool needed to compete with companies like Tesla and Rivian. They are staffed to design ICE vehicles, which is a very different exercise than designing BEVs. They are staffed to design devices that change chemical energy into mechanical energy. A BEV changes electrical energy into mechanical energy. Two very different activities. Retraining, hiring, and developing this talent will take them years.
I didn't even mention the fact that efficiently building a BEV is different than building an ICE. Changing will require more training and development for their manufacturing engineers. Again, a long process.
Most of the talking heads on Wall Street are too ignorant to understand any of this.
Edit: I completely left out all the chemical engineering expertise needed for battery development. Pretty sure this talent pool is minimal at most legacy automakers.
