We’ll start with the designation, as SLP has chosen to bring back the GNX moniker from the 80s’. Under the hood, the 2.0-liter turbocharged engine will be boosted from the standard 270 hp to at least 305 hp, which is still less than the Insignia OPC’s 321 hp .

In addition to that, the GS will be gifted with a muscular exterior package, as you can see in the adjacent rendering, as well as a set of lightweight alloy wheels. We’re also expecting the suspension and the brakes to be upgraded, but the company hasn’t mentioned anything about this.

Before we end, we have to remind you that the original 1987 Buick Regal GNX, was named after the NASCAR Grand National series and offer performance, albeit in a straight line, for an afforbadle price, with the vehicle being powered by a 3.8-liter V6 that delivered 280 hp.
