Will that be gas or "H"?

"The RENESIS Hydrogen RE allows the RX-8 concept to
run on either hydrogen fuel or gasoline and
capitalizes on all the advantages of the rotary to
assure RX-8’s ease-of-operation and reliability.

The RENESIS Hydrogen RE incorporates an electronically
controlled hydrogen injector system, with the hydrogen
injected in a gaseous state. The system draws air from
the side port during the intake cycle and uses dual
hydrogen injectors in each of the engine’s twin
rotor housings to directly inject hydrogen into the
intake chambers.

Because it offers separate chambers for intake and
combustion, the rotary engine is ideal for burning
hydrogen without the backfiring that can occur in a
traditional piston engine. The separate induction
chamber also provides a safer temperature for fitting
the dual hydrogen injectors with their rubber seals,
which are susceptible to the high temperatures
encountered in a conventional reciprocating piston
engine.

Also helping to maximize the benefits of the rotary
engine in hydrogen combustion mode, the RENESIS
Hydrogen RE features adequate space for the
installation of two injectors per intake chamber.
Because hydrogen has an extremely low density, a much
greater injection volume is required compared with
gasoline, thus demanding the use of more than one
injector. Typically, this can be difficult to achieve
with a conventional reciprocating piston engine
because of the structural constraints that prevent
mounting injectors in the combustion chamber. However,
with its twin hydrogen injectors, the RENESIS Hydrogen
RE is both practical and able to deliver sufficient
power."

MAZDA SENKU
The Senku is the revolutionary new concept coupe from Mazda. At
once dynamic and supremely elegant, it is a self-assured and mature
sports car that seats four adults. And with its combination rotary,
direct injection, hybrid drivetrain, the Senku is our pride and joy.
The interior is a prestigious environment, strikingly spacious and
equally emboldened with jet black and red embellishments. Large
flying wing sliding doors allow smooth entry and exit, even for the
rear seats. To meet and surpass the increasing challenges of
environmental and safety requirements, as well as your evolving
needs, Mazda continues to offer unrivalled driving dynamics while
achieving harmony with societal changes. The Senku is a radical
new direction in the genre of sports cars.
