The Japanese from Toyota have also unveiled a couple of concepts at the Auto China 2012 in Beijing yesterday.
The first two are called Dear Qin and are basically two vehicle variants that preview an upcoming model for the global market.
The Dear Qin design studies are for a 4-door sedan and a 5-door hatchback, with the automaker claiming that we are looking at two vehicles that fallow new principles in terms of design, something which will also characterise the production version models as Toyota want to "attract more people to the user base".
Due to the fact that Dear Qin is about teasing a new design, there are no powertrain or technology details available yet.
