Mazda Develops Improved Four Cylinder Engines

by Mazda in the News on October 14, 2009

Automakers are focusing on future powertrains for major reasons. First, consumers are demanding more fuel efficient engines. Secondly, new emissions regulations have placed pressure on automakers to reduce their fleet-wide fuel economy. While some automakers that have truck and SUV heavy lineup are a little more at risk, even Mazda is researching new ways to build fuel efficient gasoline and diesel engines.

Mazda’s goal is to reduce the fuel economy of its lineup globally by the year 2015 according to Alberta Mazda dealers. The earliest result of this push will be a new four cylinder engine that will be introduced in 2011. A redesigned version of the familiar 2.0-liter four cylinder engine and an all-new six-speed automatic transmission will help increase fuel mileage in city driving from 22 mpg to 32 mpg. A used Mazda dealer Calgary believes the strategy was to make such technology widely available, and not to limit it to just a few vehicles within Mazda’s global lineup. While no specific vehicle has been identified to receive this new engine, sources say it could be applied to numerous existing vehicles without significant modification.

Two vehicles that will likely receive new fuel efficient engines first are the Mazda MX-5 roadster and the Mazda5 MPV. Not only will these engines be available fleet wide by 2015, but Mazda Calgary suggests they will give consumers added fuel efficiency without the added costs usually associated with regenerative braking and hybrid powertrains.

Rotary engines, such as the one found on the Mazda RX-7, are also continually being developed by the automaker. The next generation rotary engine is said to have more than 30 percent improved fuel economy, while also featuring reduced weight over the existing engine.
