That has always seemed like an unlikely proposition but Motor Trend is reporting designers have created a four-door coupe variant of the critically acclaimed concept. 

Little is known about the model but it reportedly has a longer wheelbase and two rear doors.  These changes could prove pivotal as they significantly improve the chances of a production variant.

The report goes on to say GM CEO Mary Barra is a supporter of the car and a production variant could ride on the rear-wheel-drive Alpha platform that underpins the Chevrolet Camaro and Cadillac ATS / CTS.  There is even speculation that the model could be sold overseas as a Holden, Opel, and Vauxhall.

Engine options would reportedly include a turbocharged 2.0-liter four-cylinder with 275 horsepower and a biturbo 3.0-liter V6 that develops 400 hp.  Sources have said a V8 engine is out of the question but there could be a high-performance model with a biturbo 3.6-liter V6 engine that develops up to 464 hp.
