Japanese firm sticks to combustion engines and efficiency tech
15 March 2010

Mazda is pushing ahead with development of its next-generation diesel models, despite the increasingly strong push towards petrol-electric hybrids.

The Japanese firm launched a new range of diesel powerplants last year, called Sky D. The motors feature two-stage turbochargers, low-friction engine blocks, direct injection and piezo-electric injectors.

The SKy D unit will feature in the next-generation Mazda 6, which is due in 2012. Mazda sources indicate that the Mondeo rival should be capable of emitting just 105g/km when equipped with the powerplant and accompanying efficiency tech including stop-start, a special six-speed transmission and regenerative braking.

Mazda believes that more efficient internal combustion engines - petrol and diesel - and its push towards lighter vehicles will remain relevant well into the middle of this decade.

Nice to see they're following where BMW have been for three years =P

I wonder if they've yet cottoned onto the fact that you can make diesels from aluminium? BMW, Merc and Subaru have proved it, yet surprisingly few others have followed suit...

They have cottoned on, the Sky-D is an all-aluminium 2.2 diesel which should achieve EU6 emissions standard without the AdBlue urea tank.

BMW and Mercs are not really paragons of reliability, so I would say stick to cast iron....

Well, since my neighbour's ally-block 535d has done 340,000 miles faultlessly, I would tend to disagree. Anyway, BMW diesel engines' problems (yes, I am aware of them) seem to be dominated by turbo trouble, it's nothing to do with the block or heads.

Mercedes came 3rd in the latest UK JD Power Customer Satisfaction Survey...I hardly doubt they would have placed so high up the table if they weren't reliable...
