While no official word has come out of Japan as to when and if a new Mazda RX-7 will be put into production, the chief engineer at Mazda has gone on record stating that he will bring the RX-7 back during his tenure. Many concepts have arisen over the past few years that are definite to be part of the new RX-7 styling, however no official design has been made public. Here are some rumored concepts to be part of the styling:
The new RX-7 is rumored to be equipped with a new 16X 2 rotor rotary engine (1600cc displacement). This engine is based on the side port technology used in the current RX-8 “Renesis” engine. While this engine does improve gas mileage, it only produced a lack luster 235hp, and dyno’s of RX-8s are common to only show 180-190 rear wheel horse power. This is a far cry from the original 255 flywheel and 225 to the wheels that the original RX-7 provided. Not to mention the huge aftermarket gains the original RX-7 13B could provide (up to 350-400hp on stock block).
As a rotary fan, I am hoping Mazda will release a rotary engine capable of handling forced induction (whether it be a turbo or supercharger).
