To say that the Buick Avista concept may preview a future production model of some sort is a reasonably safe bet, but word out of the US suggests that the road-going version may surprise a few people.
Motortrend reports that the 2+2 coupe design seen at the Detroit Auto Show last month will gain a second pair of doors before it gets the green light from the bean-counters.
This would, in theory, make the Avista a four-door coupe - and quash any rumours that the concept would go in to bat as a Buick-badged Ford Mustang rival.
The additional doors would also require extra metal between the front and rear wheels, ensuring rear-seat passengers aren’t left wanting for leg room.
According to unnamed company insiders, GM is reportedly treating the project with enough enthusiasm that it ordered a mock-up model of the finished product to be made.
While the switch to four doors may save the Avista from a sales-war against the might of the Mustang, it may thrust the production version into the path of luxury long-wheelbase models from Germany - such as the BMW 6 Series Gran Coupe and Porsche Panamera.
But if the Avista does make it to the starting line for production, Buick is reportedly keen to see it become the company’s halo car. This would ensure the model is an all-out effort, and would likely be priced as such.
The model would also become the first four-door coupe in the entire GM catalogue, and a four-door, long-wheelbase version could increase its appeal customers in China.
A road-going Avista - two- or four-door - would be a long-shot to be built in right-hand-drive, and an even longer-shot for an Australian debut.
