Thanks to some revisions made to the platform, which is shared with the Buick LaCrosse, Chevy Impala, and Chevy Malibu, the Insignia will shed over 385 pounds despite being larger than its predecessor. New engine and transmission options will keep fuel economy high while plug-in hybrid variants will be kept on tap for the diehard fuel savers. General Motors will likely debut the Insignia before it rolls out the Buick Regal, so if you want a distilled version of the Avista’s styling, keep an eye out. With the unofficial early reveal of the Buick Regal now being over with, let’s hope that GM takes cues from its other pretty concept, the Cadillac Escala
, to build the next generation of Caddies.
