Mazda RX-8 Hydrogen Concept

The RENESIS hydrogen rotary engine technology is currently undergoing running tests in a special-edition Mazda RX-8 Hydrogen RE test vehicle. The test vehicle is equipped with a dual-fuel system that consists of a high-pressure hydrogen tank and separate gasoline tank, and can run on either hydrogen or gasoline. It is as reliable and easy to operate when running on hydrogen as on gasoline.

In addition to the revolutionary RENESIS rotary engine, the Mazda RX-8 Hydrogen RE test vehicle benefits from improved aerodynamics, optimised tires and weight-saving measures, as well as a host of technologies for exceptional environmental compatibility. These include three layers of wet-on paint, a water-based paint that dramatically reduces emission of organic solvents, saves energy by shortening the drying process and reduces CO2.

For interior parts, plant-based plastic are used, which are an attractive alternative to plastics derived from fossil fuels such as petroleum. Plant-based fibre-reinforced extrusion-moulded plastic employing cellulose extracted from timber is used for quarter panels, and reduces CO2 emissions. The hydrogen test vehicle also features low-resistance brakes and a fast-fill tandem master cylinder reduces brake drag along with low-resistance hub carriers for reduced friction that help cut power losses.
