The final chapter of the Mazda RX-8, the only model which utilises a rotary engine, is coming to a close. But there is still hope for the rotary engine. However, Mazda is not ready to let go of the rotary engine just yet. Rumor has it that Mazda is in the early stages of a rotary sports car, perhaps the newest RX-7 model.
Mazda’s engineers are currently working on the Wankel rotary engine, striving to make it more efficient while also cutting CO2 emissions to continue with Mazda’s environmentally friendly efforts. A senior insider at Mazda says that if the new rotary sports car obtains the proper funding, the goal is to cut CO2 emissions from the current RX-8 level of 299g/km to just 130g/km.
One way Mazda is trying to achieve this cut in emissions is through the use of laser ignition. Eliminating the need for spark plugs, laser ignition allows for easier combustion chamber sealing. Supposedly, the new rotary sports car will be modeled after the MX-5’s platform and would eliminate the reverse door featured on the RX-8, making the vehicle weigh much less than its predecessors. These changes along with the use of lighter materials and installing an auto stop/start capability will result in an increased efficiency.
Of course micro-hybrid technology is also a huge step toward fuel efficiency, as Mazda knows. Allegedly, Mazda has met with Audi to discuss the possibility of a range-extending rotary engine. This collaboration is no surprise considering that the new Audi A1 hatchback-based e-tron concept utilizes a 254cc Wankel engine to extend its range. Rumor has it that Mazda is looking to partner with Audi, having the German company reproduce their engine system for the new Mazda rotary sports car.
However, Mazda is keeping its lips sealed. There is no definite answer about the future of Mazda’s rotary sports car. A Car and Driver report outright denied any plans for a hybrid sports car and even said that the rotary engine was going into extinction. On the other hand, an Inside Line report asserted that work on the Wankel engine is in fact already under way, making the possibility of a rotary sports car very likely.
Time will tell whether Mazda continues the legacy of the rotary engine. Many auto enthusiasts are thrilled by the thought of a rotary engine RX-7. The truth about Mazda’s plans may remain unknown but it is safe to say that technology could take Mazda’s next sports car design in any direction it chooses.
