Mazda publish details of next-generation powertrain technologies

The new powertrain technologies (SkyActiv) include completely new engines, transmissions, bodyshells and platforms that will be launched in 2011 making major reductions in fuel consumption and CO2 emissions for all Mazda models possible.

This process will initially concentrate on lightweight construction as a core value of the brand, along with the optimisation of conventional powertrain technologies. In further phases, efficiency improving technologies, such as regenerative brake systems and hybrid power systems, will be successively introduced.

Mazda's goal is to lower the fuel consumption of its global fleet by 30 percent by 2015 (compared to 2008).

The new SkyActiv -D diesel engine sets a new record for compression ratio at 14.0:1. This results in a drop in fuel consumption of 20 percent and especially clean combustion. Without expensive after-treatment to reduce NOx, the new Mazda SkyActiv -D engine will meet future Euro 6 emission standards.

Mazda has developed a new SkyActiv -Drive automatic transmission as part of its SkyActiv technology that combines the advantages of a conventional automatic transmission, a continuously-variable transmission and a double-clutch transmission. The new SkyActiv -Drive delivers improved fuel economy of up to 7 percent compared to a current, conventional torque-converter automatic transmission.

Mazda is convinced that lowering vehicle weight is a key factor in lowering fuel consumption and CO2 emissions. A central role in this will be played by the new body structure SkyActiv -Body and the vehicle platform SkyActiv -Chassis. The newly-developed, high-strength bodyshell is 8 percent lighter and 30 percent stiffer, and combines outstanding crash safety with an excellent foundation for agile handling attributes.
