Looked it up, couldn’t find anything.
You would make your newest car, and put it on the market. Your marketing dude would bring up a list of other cars available in the target market and these real-world companies would be among those provided. You’d have your car, some AI created (or however you plan on doing that) cars, and some from Ford, Toyota, Bugatti, whatever. I don’t mean full on rendering them in game, but more a still and brief descriptions.
I am pretty sure there won’t be real car companies names or cars on the game, due to copyright problems.
But the beta team will be very creative when it comes to making parodies of those companies 
Obviously. I’m not asking to make an in-game mustang knock-off. Just call up Ford, be like “Yo, would you throw a fit if we used an image of your cars, in public domain, for our game?” Of course, you’d give them proper credit.
Still a legal minefield IMO, it might not be “copyright” infringement per se, but there are other legal matters such as “Passing Off”.
Also I’m pretty sure most, if not all, real world companies would want some degree of control over how their products are used and their perception of that use may differ from those of the developers.
IMO the devs shoud steer clear of any such issues, the last thing we want is an injunction banning the game and legal costs and penalties bankrupting the guys because someone took exception.
As mentioned above already, it’s quite a risk to do so even with “ringing companies up”. As numerous other games have done, the easiest way would be to create replicas, as Leonardo has said.
That way, we can play along in a totally different realm where you have to conform to what companies around you are producing instead of knowing exactly what the car is like just from the name.
Nevertheless, I’m sure a modder (Or possibly anyone) will be able to edit text strings and such, although I’m not sure what system the devs will be using to generate the AI vehicles yet.
