Mazda to further refine Wankel rotary engine for more efficiency?
Like the classic 13B engine that the current Renesis is still based on, the new 16X would use two rotors, though enlarged to 800cc each for a total of 1.6 liters. Despite the increase in displacement, Mazda hopes to increase fuel economy and reduce emissions by 20 percent.
Other efficiency improvements are planned as well, including a dual-clutch transmission and a significant weight savings over the current RX-8, which isn't exactly a porker as it is. Supposedly, the new rotary would be available in both a two-door, two-seat RX-7 and a larger, four-seat RX-9 variants.
