Toyota hybrid at 2013 Frankfurt motor Show (IAA), next gen Prius
Toyota hybrid is a core area of development for the company, an the next gen Prius is one in a range of Toyota and Lexus vehicles to use an improved family of hybrid powertrains. The lighter, more compact and efficient Toyota hybrid powertrain delivers fuel economy improvement.
Next Prius adopts Toyota New Global Architecture, with a lower centre of gravity and stronger structure delivering improved dynamic performance. Next gen Plug-in is developed in parallel with standard Prius. Touyota heads to the 2013 Frankfurt motor show with focus on its hybrid leadership.
The next Prius will feature improved batteries with higher energy density, which means greater energy storage capacity within a smaller unit. Toyota, already a leader in advanced battery technology, has stepped up its research, development and production capacity for both nickel metal-hydride and lithium-ion, and will use each technology where appropriate in it expanding focus on vehicle electrification. It has also ramped up development of new battery technologies such as solid state and lithium-air, and devoted resources to chemistries beyond lithium, such as magnesium and other low-valence materials.
The next Prius will use smaller electric motors, but with a higher power density. The motors in the current model have four times the power density of those used by the original Prius back in 1999, and the improvement will be higher still in the next generation car.
The thermal efficiency of the petrol engine will improve, too, from 38.5 per cent currently to a world-best of more than 40 per cent.
The next Prius will be constructed according to the Toyota New Global Architecture, bringing a lower centre of gravity and greater structural rigidity, contributing to greatly improved driving dynamics.
A focus on raising aerodynamic performance will deliver an all-new exterior styling, with a larger interior and refinements in design, layout and ease of use.
The next generation Prius Plug-in is being developed in parallel with the standard Prius model. Toyota has learned from current Prius Plug-in customers that they would like a greater all-electric driving range and a more convenient charging solution. In response, Toyota is working on a new wireless/inductive charging system that produces resonance between an on-floor coil and an on-board coil to transmit power to the battery – simply put, this provides charging without the fuss of connecting a cable. Verification work on this system will be carried out in Japan, the USA and Europe during 2014.
