Washington DC August 21, 2009; The AIADA newsletter reported that Mazda will introduce a more fuel-efficient powertrain by 2011, kick-starting its pledge to increase fuel economy across its model line 30 percent by 2015.

According to Automotive News, Mazda is developing a range of four-cylinder and rotary engines that are expected to result in higher fuel economy ratings. For example, a redesign of Mazda's best-selling 2.0-liter four-cylinder engine with a new six-speed automatic transmission will see city fuel economy increase to 32 MPG from 22. Highway fuel economy would increase to 42 MPG from 32.

Mazda did not say which engine or vehicle would be the first to market with the increased efficiency. Given Mazda's product cadence, the redesigned MX-5 convertible or Mazda5 small minivan likely would get the new engines first.

The entire model lineup will be equipped with the new engines by 2015. Mazda also is concentrating its research and development resources on rotary engines. The next-generation 1.6-liter rotary is expected to have a "greater than 30 percent" fuel economy improvement while saving weight.

Mazda also is studying bringing its next-generation diesel engines to the United States.
