To be showed in at next month’s Tokyo motor show, the four-cylinder 2.0-litre petrol SKY-G and 2.2-litre diesel SKY-D engines use latest fuel-injection designs, low-friction cylinder blocks and other technologies to cut fuel consumption by up to 15 and 20 per cent respectively. From Australia is the latest and newest generation Mazda direct-injection petrol and diesel engines that apparently produce Mazda2-type efficiency in a Mazda6-size car.
They will go into manufacture in Japan from 2011 and be phased in across a wide range of Mazda models for world-wide release, including Australia.
The engines will be mated with a new automatic transmission, called SKY-Drive, which Mazda says uses low-friction technologies to cut fuel use by a further five per cent while delivering the “feel” of a dual-clutch gearbox.
The powertrain line-up is part of Mazda’s previously announced ‘Sustainable Zoom-Zoom’ push to cut fuel consumption by 30 per cent by 2015 over 2008 levels – a project that also includes technologies such as idle-stop, light-weight construction and, ultimately, hybrid and perhaps hydrogen powertrains.
The SKY-G (for gasoline) engine and the SKY-Drive transmission will be shown at the Tokyo show in Mazda’s recycled Kiyora concept car that was originally revealed at the Paris motor show last year.
Mazda maintains the combination of featherweight Kiyora body and new SKY-G powertrain can achieve 3.1L/100km fuel economy – 0.8L/100km better than Toyota’s hybrid Prius and less than half the official 8.4L/100km figure achieved by the current petrol 2.5-litre Mazda6.
