Mazda pledged that its next generation of petrol-engine vehicles will be cleaner than electric cars due to the use of efficiency-boosting compression ignition technology - and it'll boost that promise in 2021, when a plug-in hybrid (PHEV) drivetrain will join the range.
The PHEV system will be the last of the planned drivetrains to be added to the Skyactiv-X range. The first to arrive will be the new petrol engines, which will replace the current Skyactiv-G units in 2019. These engines use compression ignition technology that has previously only been used in diesel engines. Mazda claims they are 30% more efficient than its current petrol units, matching or even improving on the brand’s Skyactiv-D diesel engine range.
Alongside the launch of these groundbreaking petrol units, the Japanese brand will add mild hybrid and full electric drivetrains to its line-up in 2019. The latter will be available in pure battery EV form or with a range extender engine. The technology will be shared with Toyota, which Mazda has recently teamed up with for research and development. The next Mazda 3 will also arrive in 2019, suggesting it could be an early benefiter of the new powertrains.
Interestingly, despite the zero tailpipe emissions of electric vehicles, Mazda claims that its Skyactiv-X engines will actually be the cleanest power sources in its range. Mazda said they'll produce lower carbon dioxide emissions than electric powertrains from a 'well-to-wheel' perspective - which accounts for the whole life cycle of a vehicle and the fuel needed to power it. The company has been developing the new engine technology for several years, as first reported by Autocar in 2014.
