Mazda to focus on better fuel efficiency in new-generation SkyActiv motors
Mazda’s new-generation CX-9 was the company’s first model to have a turbocharger in its range of gasoline-powered SkyActiv engines. It appears however that the CX-9 will be the first and last model to get a turbocharged SkyActiv gasoline motor after Drive AU reported that it will be the lone model to have that kind of technology.
Mazda stated that it has no plans of following the trend of downsizing and turbocharging gasoline engines as the use of forced induction will still yield higher fuel consumption.
“If you start using the power of the turbocharger, you suddenly start to use more fuel. Small capacity turbos are not on our horizon,” said Alastair Doak, director of marketing at Mazda Australia.
Doak also stated that the company can achieve better fuel economy results from the next-generation of SkyActiv engines. He even stated that the company expects the new engines to deliver between 25 to 30 percent better fuel efficiency.
Exact details are not yet available but Doak believed it could be achieved by tinkering with the already high compression ratio of the engines which are already at 10 or 11:1.
“In any case, the next-generation of SkyActiv engines are still years away, added Doak.
Those expecting a turbocharged MX-5 in the near future will not be getting their wishes granted as chief designer Masahi Nakayama also stated that the current roadster will remain naturally aspirated.
“The MX-5 has always been about throttle response and feel rather than outright power, so a turbo is not necessary,” said Nakayama.
