Seems like a long time from now, but Mazda is planning on increasing their fleet fuel economy by 30% over the next five or six years.
Mazda will be working on its powertrain, but without giving up the rotary engine. They are looking to add in idle-stop (start-stop technology) and direct injection spark ignition. That may also lead to regenerative braking, electric power steering, and electric water pumps.
The direct injection spark ignition will have a combination of smaller displacement, higher power output, and greater efficiency. It's estimated the 2.0 liter four-cylinder engines paired with the new transmissions will increase city and highway fuel economy by 10 mpg to 32 and 42 mpg, respectively.
Mazda is also considering lightening up the frame using alternate structural materials and new bonding tech.
The next generation of engines will most likely start with the redesign of the 2013 RX-8, Mazda 5, or the MX-5 Miata.
