The configuration is identical to the Lacrosse eAssist, which launched in China earlier this year. The Alpheon eAssist returns 33.2 mpg on the U.S. cycle, which is a fairly impressive figure for a comfortable sedan. So far, there's no word on what sort of price premium the vehicle will carry when it goes on sale.
As with other General Motors eAssist models, the changes to the Alpheon aren't solely mechanical. The instrument cluster boasts an Eco gauge designed to help coach drivers toward more efficient operation, and the vehicle is equipped with low-rolling resistance tires as well.
