Mazda says it will reduce the fuel consumption of its cars 30 percent by 2015, according to Autopia, in a global effort that will see the automaker revise almost every engine in its roster, cut at least 220 pounds from every car it builds, and continue to develop its hydrogen hybrid system—moves that come as the auto industry reels from record-high gas prices, a decline in SUV sales, and flat (at best) car sales.

For starters, the company plans to introduce a start-stop system. According to the report, the system stops the engine at idle, then restarts it by forcing fuel directly into the cylinder and igniting it to start the car—a procedure Mazda said is quieter and improved fuel economy as much as 8 percent in testing.

The company is also launching an E85 flex fuel engine and a thoroughly revised, more efficient rotary engine for the RX-8. After that, they'll begin to introduce direct-injection turbo diesels and direct-injection spark ignition gas engines, the latter of which will improve fuel economy by 15 to 20 percent compared to its current lineup.
