Mazda has today confirmed that it will at last spill the beans on its Skyactiv fuel-saving engines and transmissions at this month's New York Auto Show.
The news follows the unveiling in February of the 2012 Mazda3, which will feature the new Skyactiv-G petrol engine and SkyActiv-Drive automatic transmission when it arrives in Australia later this year.
The Japanese carmaker first announced plans for ultra-efficient petrol and diesel engins back in 2009, but details and figures for the new SkyActiv range have remained a tightly-held secret.
There are promising signs however: it was revealed last year that the small 1.3 litre version of the engine will use just 3.3 l/100km of petrol - down from the 5.4 l/100km of the current 1.3 litre engine used in Japan.
In Australia, Mazda's 1.5 litre engine, which powers the Mazda2, uses 6.4 l/100km of petrol in manual guise.
A diesel engine will also feature in the SkyActive line, and a test drive in February of a SkyActiv-D powered Mazda6 revealed a strong future.
"Quite simply, it drove like no other diesel of my recent experience. Lighter on the inside - conrods, crank, pistons, skirts - and out, and with a compression ratio of just 14:1, the SkyActiv-D diesel spins as readily and effortlessly as a petrol engine," TMR's Tim O'Brien wrote.

The New York Auto Show will also play host to the Minagi concept, which is expected to debut in production form in the coming year - possibly as a sub-CX-7 'CX-5' compact SUV.
