SLP released a preview of what they have in mind for tuning the Buick Regal GS.
The Europeans recognize this car as the Opel/Vauxhall Insignia OPC/VXR. The thing is, SLP have bought the rights to call this car the GNX, which is an old Buick nameplate.
The SLP tuning package for the sporty Regal includes a body kit, as showed in the sketch above, with fender flares, revised fascia, and new side skirts. One would imagine it also includes a rear diffuser and a number of tailpipes.The Regal is a good looking car. This package will only make it better.
More importantly though, the 270hp engine will get a boost to over 300 hp. The project is limited to 500 cars.
