Hiroshima, Japan – The Mazda Motor Corporation has announced that it is planning to reduce the fuel consumption of Mazda vehicles sold globally by an average 30 per cent by 2015. The commitment will entail using lightweight technologies, an upgrade of almost all gasoline engines, the introduction of a Smart Idle Stop System, a new gasoline rotary engine and new diesel engines worldwide.

By 2015, Mazda will have renewed almost its entire powertrain line-up, and from 2011, aims to reduce the weight of its new vehicles by 100 kg or more through development of safe, lightweight, new-generation platforms.

From 2001 to 2008, the average fuel economy of Mazda vehicles sold in Japan increased by approximately 30 per cent, and in 1991, the company embarked on a long-term project to develop vehicles powered by hydrogen technology.

The company will introduce the mass production version of its proprietary Smart Idle Stop System into one of its cars in 2009. The unique system restarts the engine from idle by injecting fuel directly into the cylinder and igniting it to force the piston down, enabling a fast and quiet start, and a fuel economy improvement of up to 7 to 8 per cent. The system will initially appear in Japan and Europe and eventually be rolled out worldwide.

The company has also announced an E85 flexible-fuel engine in Northern Europe and North American markets in 2009; next-generation Direct Injection Spark Ignition and other systems to boost power and improve fuel economy from 2011 onwards; new diesel engines worldwide beginning in 2011 that meet the strictest future exhaust gas regulations in each market; and a substantially upgraded gasoline rotary engine in the early 2010s. In addition, it plans to have an eco-friendly bio-plastic, made from non-food-based cellulosic biomass, ready for use in vehicles by 2013.
