LOS ANGELES – Buick unveils the 2012 LaCrosse with eAssist,™ a new fuel-saving technology that increases fuel economy by 25 percent compared to the four-cylinder/six-speed powertrain in the 2011 LaCrosse. The eAssist technology provides class-leading highway fuel economy of 37 mpg, while maintaining the luxury, performance and value expected from Buick’s flagship sedan.

Not a whole lot new there, unless they think a belt driven motor generator is "new", eAssist is just another way of saying hybrid...

"eAssist" may sell better than "hybrid" though.
