Daimler Mercedes Benz.
Daimler + Chrysler (now Fiat Chrysler), Daimler + Tesla, Daimler + Google and most recently Daimler + Nissan + Renault.
Car companies create so many strategic partnerships it's like Game of Thrones.
Most new technology comes from F1 where they really push the envelope.
At the risk of pushing off topic that’s not entirely correct.
You’re confusing ownership or part ownership for partnerships involving intellectual property sharing which is rarely the case in the Daimler AG group of companies and more so for Mercedes-Benz who relentlessly protects their property.
In some cases there is a business sale of some hardware.
Daimler AG dropped Chrysler like a hot potato when they realised what an awful fit it was to their business model.
They couldn’t sell it quick or cheap enough and just wanted to be rid of the mess.
And even during the Daimler ownership period Mercedes would only allow Chrysler access to their old tech.
For example the owners of ML Class Benz’s from 15 years ago will notice many similarities in the interiors of the newer Jeeps plus the cars being based on the old Mercedes designed chassis, they were never given access to the newer stuff.
Mercedes has never been willing to share much of its current or up and coming tech.
Mercedes-Benz main innovation focus for many years has been on safety and in particular the avoidance of accidents.
Mercedes has long been an opponent of the NCAP type safety ratings as they say it gives little credit to manufactures that fill their vehicles chock-a-block with avoidance systems which don’t rate any better than manufacturers who offer very little.
They are on record saying when it comes to NCAP you want to hope the car has an accident in the exact same spot where the test is carried out as many cars are only built to pass in those areas and they also say that when you have an accident at 100km or more you are in the hands of God as no vehicle can save you.
The cabin may retain complete integrity but the occupants will be dead because their internal organs are turned to mush from the sudden stop.
There are other manufacturers who push the envelope like Mercedes but many others are just also-rans who years after the fact ride on the back of the true innovators.
Here’s some of the systems Louis Hamilton has been using in F1 for years. :rofl:
