The RX-8 successor (earlier post) is at least one year behind schedule, due to failure in meeting the emission requirements. Mitsuo Hitomi, general manager of Mazda's powertrain division, insists that "we will never give up" and the 16X Wankel engine under development is already 30% more fuel efficient that the Renesis engine. Hitomi stated that the 1.6L 16X engine is slightly more fuel efficient than Mazda's 2.0L petrol engine.
So, when the new RX will hit the market? "Maybe within two years we can tell you when we will introduce it to the market," according to Hitomi.
