Mazda’s new Skyactiv-D efficient diesel engine technologies are helping to switch motorists to cleaner diesel engines, the company claims.
While diesel cars are already very popular in Europe, where more than half of all new cars sold come with an oil-burner, in Japan they represent a mere 0.4 per cent of sales.
Yet the launch of Mazda’s CX-5 last year has led to the four out of five models sold in Japan to come fitted with the 2.2-litre SKYACTIV-D under the bonnet.
Currently, SKYACTIV engines, transmissions, chassis and body technologies are available in the UK on CX-5 compact SUV models, and the all-new Mazda6 Saloon and Tourer – with the addition of the i-ELOOP unique brake energy regeneration system that can boost fuel economy by up to 10 per cent.
What makes the firm particularly proud of its Skyactiv diesel technology is a 14:1 compression ration-unusually low for a diesel– which enhances fuel combustion and efficiency, while reducing harmful emissions, especially of nitrogen oxides (NOx).
Euro 6 emissions
It’s the only diesel to comply with Euro 6 emission standards without NOx after-treatment – long before the new standard takes effect in September 2014.
The engine’s variable twin turbocharger boosts torque and responsiveness throughout the rev range right up to the unusually high redline of well over 5,000rpm. Yet it still delivers best-in-class fuel economy and CO2 emissions – from 119g/km and up to 61.4mpg in the CX-5 and from 108g/km and up to 67.3mpg on the all-new Mazda6 sedan.
Mazda’s clean diesel technology is now destined for North America, another traditionally weak diesel market (at around 3 per cent). Scheduled for arrival later in 2013, the all-new Mazda6 will be the first passenger car powered by a modern clean diesel to be offered by any Asian manufacturer in the USA.
“Mazda’s SKYACTIV-D engines have what it takes to change people’s attitudes and overturn the negative preconceptions towards diesels that prevail in the U.S. and Canada,” explains Mazda North America President and CEO Jim O’Sullivan. “We think they’re going to make a huge splash, especially when you consider how our clean diesel technology addresses growing consumer concerns about rising fuel costs and the environment.”
Another advantage of the SKYACTIV-D is that it not only meets strict emissions requirements in Europe, but also in Japan and North America.
