Imagine a ZF tie up with either Bosch or Continental.
It's kinda happening with shared supply chains and specialization. While ZF sold their steering business to Bosch and Conti bought out INA and Siemens VDO, they all depend on each other for things they can't make or OEM integration. Bosch does have the most experiences with electronics - and ZF would use Bosch ECMs or mechatronics.
In Japan, while Mitsubishi Motors isn't really considered part of the mothership, Mitsubishi Electric supplies all the Japanese automakers and suppliers with electrical bits. So does Panasonic and Hitachi. As a matter of fact, Hitachi did acquire Honda's main electronics/engine/chassis suppliers - Keihin/Nissin/Showa. Hitachi is a long-time Nissan/Subaru supplier who bought out Unisia JECS and Tokico. Hitachi, Nissan and Subaru were all joined at the hips at some point in time.
Seems like Borg-Warner wants to become a one-stop shop for powertrain, electronics and chassis. They did buy out Delco Remy a few years ago - also a former part of GM. Haldex and KKK(the turbo) were more recent acquisitions. It seems like while they might not get too much Japanese/Korean OEM business except for Honda(SH-AWD and VTM-4 are Borg-Warner), they want to solidify business with GM, VAG and the Chinese(Volvo uses Haldex AWD, Geely owns Volvo).
Toyota controls Denso/Aisin/JTEKT and Hyundai is getting more vertically integrated with their Powertech/Mobis/WIA divisions. But BW might try to get more Toyota or Hyundai business too.
