abro aqui um novo tópico para irmos acompanhando o evoluir do lançamento ainda este ano e para já apenas no Japão do novo modelo HIBRIDO da Mazda 5 que vai ter a designação oficial de "Mazda Premacy Hydrogen RE Hybrid" e que faz parte do "Mazda Green Plan 2010" que está em curso desde 2005.

"The Mazda Premacy Hydrogen RE (rotary engine) Hybrid concept features a hybrid power unit that combines a dual-fuel, hydrogen/gasoline rotary engine with an electric motor. The power unit is transversely mounted at the front in a front-wheel drive layout. The development team aimed to produce a vehicle with outstanding driving and environmental performance along with a comfortable, roomy interior".



alguém sabe mais algumas novidades sobre este lançamento?
para quando na Europa?

Já tinha visto umas imagens mas tem um senão, que é o espaço ocupado pelo depósito do hidrogénio. Não encontrei as fotografias, mas encontrei um esquema:

The RENESIS hydrogen rotary engine employs Mazda-developed RE technology to achieve high power output with lower emissions. In particular, electronicallycontrolled direct gas injection and EGR (Exhaust Gas Recirculation) assure the same reliability and ease of use in hydrogen mode as in gasoline mode. What’s more, only minimal modifications to the engine and chassis were required for use with hydrogen fuel. In addition, a dual fuel system is adopted featuring a high-pressure hydrogen tank as well as a gasoline tank, allowing the driver to freely switch between hydrogen and gasoline fuels as circumstances dictate.

To take the hydrogen rotary engine places it's never been before, Mazda redesigned the engine for use with FF vehicles, and integrated the Hydrogen RE with a hybrid system. The highvoltage battery is located beneath the second-row seats while the high-pressure hydrogen tank is beside the third row seat. This allows the HRE-based hybrid system to achieve both outstanding environmental performance and a comfortably roomy interior.
