Hey i didnt know where to put this but here goes. So it seems that a few of these Chinese vehicles like the E-jet are transformers in Age of Extinction according to ths article
Several Models of the GAC MOTOR Shine in Transformers 4,... -- HONG KONG, June 20, 2014 /PR Newswire UK/ --

 

Better Question, WHO are those GAC cars transformers-wise?

 

Your guess is as good as mine

 

Based on the Positive Aura and Theme of the article I doubt they would be Baddies.

 

The blue one looks like its possibly the robot mode of the silver E-jet

 

Uploading the pic makes it easier for others  

 

Don't think they'll be Transformers in the film...

 

I think some of the Generic Human built robots are are Chinese cars.

 

Richest! Repeated over & over again. Richest.

 

Nice cars nothing I would drive bots look to promote ads of cars and trnasformers film at once

 

Yeah I think at this point in the film designs when we see the entirety of a vehicle hood on a robot's chest, it's safe to say it's just for advertising the cars.

 

Promotions and nothing else.
