Apparently the ATS platform was engineered to accommodate a small-block, tipped to power a new ATS-V performance model. GM could give the GNX a lower output in order to position it below the Cadillac, but a rear-drive Buick with turbo six or V8 power could be just what the proverbial doctor ordered to give the brand a boost of excitement. The original GNX
was ushered into production by Lloyd Reuss, executive VP of GM North America in the 80s. His son Mark is now president of the same division, and just happens to own a 1987 Buick 547 GNX himself. That's reason enough for us, and we could be looking towards its debut at Detroit 2014.
