New design by Mazda is evident in their new Kodo and Shinari concept models. The design is future based and along with the looks there is also the rotary engine which incorporates cutting edge futuristic technology that is expected to reduce fuel consumption by an astounding 50 percent. Not to be fitted on the Shinari this engine is marked for installation on Mazda’s future cars.
Specific details about the engine of the future has not been revealed by Mazda expect for the name of the engine which is Sky. The focus currently is on fuel saving techniques and technology to be implemented on the engine. Their designers have said “Today we cannot name it this, but a Sky rotary engine is under development. We are not aiming for a small improvement. Fuel economy is our handicap, so we must drastically improve otherwise the next generation rotary cannot survive. But there is potentially a very large improvement available therefore it is important that we do this.”
It can only be contemplated that this would be the engine that Mazda would use on their future CX-5. Drawing on from this assumption it concludes that the engine would be a direct injection gasoline engine. The output and efficiency would have been tweaked to give higher efficiency and performance factors. The car itself being of lighter design would aid in providing higher fuel efficiency which could be expected to be about 30 percent. Also there would be the i-stop, a regenerative braking system added to the car.
A 13B twin rotor Renesis engine powers the current Mazda RX8 model. The engine develops 232 hp and gives a fuel consumption rate of 12.9 liter per 100 km and applying the mathematical formula of probability we get the future generation engine to have a fuel consumption of 7 liter per 100 km and that’s a tempting figure.
