With more and more manufacturers launching details about Hydrogen
cars, we take a look at the latest offering from Mazda. This new
prototype RX-8 is taking leaps forward to putting Hydrogen cars on our
With Hydrogen cars being in their infancies, the RX8 produced 100bhp,
somewhat less than its petrol counterpart however emissions are reduced
to water from the exhaust. At the touch of a button, the RX-8
can also revert back to its normal petrol guise.
Mazda, who still utilise the rotary engine on their RX-8 have found
it a lot more suitable to burning hydrogen than a conventional engine.
The Hydrogen/Petrol hybrid is likely to superseded by a Hydrogen/Electric
hybrid which it does not foresee to be far off.
The Mazda RX-8 RE is currently not available
in the UK however there are examples on the road in Norway and Japan
making it the worlds passenger car with a hydrogen
internal combustion engine. The majority of cars are being leased to the
Japanese governments while under testing.
It has taken 15 years of research into hydrogen vehicles for Mazda to
develop and make the RE. Although not as efficient as a
fuel cell, structurally it is closer to the petrol engine and
therefore a cheaper to produce and is far more reliable.
