The AIADA newsletter reported that Toyota will maintain an "aggressive" strategy of putting hybrid technology in more U.S. vehicles, according to North American President Jim Press.

"Hybrid isn't an alternative. It will be the heart of most of everything we drive,'' commented Mr. Press from the automaker's annual shareholders meeting in Tokyo City.

"There will be diesel hybrids, advanced gasoline hybrids, fuel-cell hybrids, ethanol hybrids.'' Mr. Press also noted that Toyota is researching diesel and fuel-cell vehicles, as well as hybrids that can be plugged in to an electric outlet for recharging, providing even more fuel economy, reports Bloomberg.

Toyota currently holds 72 percent of the U.S. hybrid market.
