GM used to allow all variants to look identical, save for the grill and wheel covers. If that's what you mean by bad badge engineering, I agree. There is no sense having clones on the market. I suppose that is the definition of badge engineering. I don't think they do that anymore though. They make enough changes in the fascias, skirts, wheels, and interiors for then to have their own identities. The Lambdas are a great example of that. So is Zeta. I am betting Alpha will continue that trend if they so choose.
