Detailed information about Mazda’s next-generation powertrain technologies has been released. These include details on new engines, transmissions, bodyshells and platforms that have been named SKYACTIV. Set to be launched in 2011, the future range will offer improved fuel efficiency and lower CO2 emissions and it will be used in all Mazda models. Mazda said that the changes will include a lightweight construction and an improvement in the existing powertrain technologies. This will be followed by the introduction of regenerative brake systems and hybrid power systems. Mazda aims to reduce the fuel consumption of its global fleet by 30% by 2015 (compared to 2008).
When looked at separately, the SKYACTIV-G petrol engine will use 15% less fuel and will come with a 15% increase in torque output. Getting higher torque at low and mid-range engine speeds means that that the vehicle gets improved driveability with less fuel consumption in daily driving. The SKYACTIV-D diesel engine will get a 20% drop in fuel consumption while being able to comply with future Euro 6 emission standards.
A two-phase turbocharger generates smooth and linear responses from low to high engine speeds and raises low and high-end torque up to the rev limit of 5,200 rpm. Mazda also has a new SKYACTIV-Drive automatic transmission in the range. Mazda claims that it combines the benefits of a conventional automatic transmission, a continuously-variable transmission and a double-clutch transmission. As a result, it offers improved torque, a direct driving sensation that is similar to a manual transmission, and better fuel economy of up to 7%. The new SKYACTIV-MT manual transmission is lightweight and compact, with lowered internal friction that aids in reducing fuel consumption. It also gets a new body structure SKYACTIV-Body (8% lighter and 30% stiffer) and a vehicle platform SKYACTIV-Chassis (14% lighter).
