Toyota has unveiled this week two new fuel-efficient gasoline engines that will serve as the basis for as many as 14 global powerplants by 2015, and boost economy by 10 percent.
Automotive News reports the two engines — 1.3-liter four-pot and 1-liter three-pot — are Atkinson cycle powerplants co-developed with partner Daihatsu, and feature fuel-efficiency goodies such as EGR, VVT and stop-start technology.
On the power front — especially since Atkinson cycle engines are more known for their efficiency than for destroying ‘Ring times — the Toyota engines will deliver high compression ratios of 13.5 for the larger engine, 11.5 for the smaller. In turn, thermal efficiency in the duo will hit a maximum of 38 percent and 37 percent, respectively.
As for where the duo and their children will reside, expect the home market to have the first crack via the automaker’s line of non-hybrid compacts before taking the global stage the following year in both non-hybrid and hybrid vehicles, as well as larger premium offerings.
