If this is accurate, this would be amazing! This would continue to move Buick up and back on the map, give it deserved respect which the Enclave is accomplishing and rid it of the stodgy, staid, AARP image which also once plagued Cadillac.
On a new Epsilon II platform replacing the aging underpinnings the current LaCrosse is based, the successor probably be similarly sized to the present generation, given that the next generation Aura (we've seen the Opel Vectra mules) is to be upsized from the current. Powerplants are not well known at this point, but I can see a DGI 3.6L V6 offered, but, I would also wonder if a V8 powered Super edition would be produced; I'm certain a V8 can be placed in a larger Epsilon II. With this and a Zeta-based flagship to succeed the Lucerne, Buicks future looks bright!!
