The fourth generation Mazda 2, which will be launched next year, will have a 1.5l Skyactiv diesel engine under its hood. The engine will come fitted with a twin turbocharger and will ensure C02 emissions are kept below 90g/km. Skyactiv is the marketing name for Mazdaâ€™s weight saving and fuel economy enhancing technologies. It has been applied to everything from engines to transmission and even body structures.
The Skyactiv 1.5l diesel engine will share a lot of mechanicals with the 2.5l oil burner that is currently offered in the CX5, Mazda 6 and Mazda 3. The engine is capable of churning out 104PS at 4000rpm and maximum torque of 250Nm comes from as low as 1500rpm. The torque output of this diesel engine is comparable to the 2.5l inline four gasoline engines powering the CX5. This just goes to show the remarkable feat that Mazda have been able to achieve.
The Skyactiv-D eliminates the need of NOx and particulate treatment in contemporary diesel engines and still meets Euro 6 emission norms. The turbocharger comes fitted with a rotation sensor and has received a water cooled intercooler built into the intake manifold to increase efficiency and acceleration response.
Stop Start technology and i-Eloop brake energy recuperation system work in unison with the Skyactiv 1.5l diesel engine to ensure that the Mazda 2 will have class leading fuel efficiency figures. This engine is expected to boost up the sales of Mazda 2 especially in Europe.
Mazda2 to have SkyActiv-D press release
|Hiroshima / Leverkusen, 11 June 2014. Mazda confirms its all-new Mazda2 will debut with the SKYACTIV-D 1.5, a brand-new 1.5-litre clean diesel engine, when the convention-challenging carmaker introduces its next-generation B-segment model, which will be initially launched in Japan.
First unveiled in March at the Geneva International Motor Show alongside the Mazda Hazumi concept (the basis for the all-new Mazda2), the SKYACTIV-D 1.5 shares much with its award-winning sibling: The SKYACTIV-D 2.2 clean diesel available for the Mazda CX-5, Mazda6 and Mazda3. The SKYACTIV-D 1.5 was developed in the pursuit of ideal combustion despite a very low compression ratio. As a result, the engine boasts outstanding dynamic performance from standstill to its unusually high redline..
New innovations for the small-displacement newcomer to the SKYACTIV range include an expanded homogenous lean burn range, even less mechanical resistance, and new insulation technology to counter the increased cooling loss associated with a smaller engine. So itâ€™s exceptionally efficient and clean, delivering top-class fuel economy and emissions, and will comply with Euro 6 without needing pricey exhaust aftertreatment.
In addition to the SKYACTIV-D 1.5, the all-new Mazda2 will come equipped with the full line-up of SKYACTIV Technology, including the highly efficient six-speed SKYACTIV-Drive automatic and SKYACTIV-MT manual transmissions. It will also have the carmakerâ€™s fuel-saving i-stop idle-stop and i-ELOOP brake energy regeneration systems. Mazda expects its new clean diesel-powered supermini to achieve the best fuel economy of any combustion-engine powered vehicle available in Japan*. The SKYACTIV-D 1.5 should be popular in Europe, too. The company believes the next Mazda2 will follow in the tracks of existing SKYACTIV-based Mazdas, among other things in terms of outstanding real-world fuel consumption and Mazdaâ€™s characteristic driving fun.
