Honda's frugal Earth Dreams engine technology is already available in the form of the Civic Hatch Diesel, but according to the Japanese automaker's executive vide president an even larger roll-out of Earth Dreams tech could come to the Civic by 2015.
And it will come in the form of a direct-injected petrol four-cylinder, most likely a 1.8 litre with 110kW and 180Nm. That engine will likely replace the current 1.8 in the Civic sedan and hatch, which produces 104kW and 174Nm.
Although the difference in output between the two 1.8s is not that dramatic, the fuel efficiency gains should be more than noticeable.
The Earth Dreams engine features a lot more technological sophistication in its double overhead cam valvetrain and direct injection fuel system, which allows it to extract more power from each drop of fuel compared against the current Civic's single overhead cam port-injected 1.8.
The Earth Dreams 1.8 will probably be available with a CVT automatic transmission too, which would offer even greater efficiency gains given it would be replacing an antiquated 5-speed auto. Currently, the Civic Hybrid is the only Civic available with a CVT.
A timeline for the expansion of Earth Dreams powertrain tech for the Civic has yet to be firmed up, but it appears likely that the direct-injected 1.8 will be added to the North American Civic range for the 2015 model year.
A local release date has yet to be made official.
