This sneak preview shows the Toyota NS4 concept car, which will be unveiled in full at the Detroit motor show in January.
Toyota hasnt confirmed whether a production version of the NS4 will be built, but it could preview design features that will be used for the next-generation Prius.
Toyota will also show the Prius C at Detroit. The supermini-sized hybrid is built for the US market and wont be sold in the UK. Instead, Toyota will launch the Yaris Hybrid in June.
