Mazda RX-9 tagged posts

Yesterday’s news that Mazda is planning a 449hp rotary engine for the RX-9 attracts many attention.

Now let us take a look at some interesting facts about the rotary engine.

Advantages about the rotary engine

1. Because there is no crankshaft, valves, pistons etc., the rotary engine is lighter, runs with less vibration;

2. Longer strokes, less prone to knocking and less pumping loss, which is more suitable for turbocharging, direct injection and lean burning;

3. Quicker throttle response;

4. Less moving parts such as pistons, valves, so rotary engine has less probability of sudden failures when compared to other traditional internal combustion piston engines.

Remember we reported the Mazda RX-8 successor – the RX-9, is coming three year later?

Most of the information in that article still holds, with one exception and it is a good news. Previously we said it will come with a 300hp, naturally aspirated rotary engine; but today we get an update that, Mazda is planning to use a turbocharged rotary engine, which is planned to output around 449hp (335kW).

Rotary engine is more suitable to be paired to turbocharging, reasons are:

1. Using turbocharging, the engine can use less quantity of rotor to achieve the same output;
2. Turbocharging can significantly boost low RPM torque, which is a weak point for the RX-8 previously;
2...

We heard a news today that Mazda is busy working on the new generation of the RX-8 successor, which is famous for its industry-unique rotary engine. One possible name for the new car will be “RX-9”.

Some preliminary details:

– Naturally aspirated rotary engine with SkyActiv technology, output around 300 hp;
– Will be available in coupe style;
– Rear wheel drive layout (of course it must be)
– Two transmission options: 5MT or 6AT;
– Will be announced in 2017.
