During a pre-Beijing Motor Show conference call today, Buick provided some more hints about the new Invicta concept that it will reveal this weekend in China. We've had a couple of teases about what to expect and won't actually be seeing any detailed images until Saturday, but what we do know now is that the Invicta (from the Latin for 'Invincible') is a four-door coupe following the current trend started by Mercedes with the sleek and sexy CLS. According to Buick designer Dave Lyons, getting a coupe to look great is easy, but the four-door layout is something that holds more market appeal. The Invicta picks up where last year's Riviera concept left off and extends that design language. It continues with what he called the "Sweep Spear" curve over the rear fender. On the inside, the cooperating design teams in Michigan and Shanghai worked to create an environment that is both functional and a reported work of art, and the driving environment is meant to impart a feeling of calm and quietness to help reduce blood pressure. Also, in spite of the low roof-line, the designers tried not to compromise rear room like in other four-door coupes. Unfortunately, at this point all we can say is, "We'll be the judge of that!" Based on the description given by GM today, the Invicta looks very promising and we will likely see hints of the next generation Lucerne in this car. But until we actually see it, it's all just hyperbole.
