@Loud_R The 2.8 twin turbo unit in the Insignia OPC is fine for an Opel. But it’s not where Buick is going as a brand.
Buick is quiet, soft-spoken luxury. The Regal, in fact, was destined to be a Saturn in the first place.
Other than that, the 2.8 doesn’t result in a much faster car…
@Pontiac_Rulz have you driven the Regal GS with its high-output 4?
