The Buick Grand National stands as one of the most formidable American performance cars of the 1980s, combining understated, all-black menace with genuine supercar-level straight-line performance. Developed at the height of the turbo era, the Grand National’s intercooled 3.8-litre turbocharged V6 delivered immense torque and rapid acceleration that famously embarrassed contemporary V8 muscle and European exotics alike, all while retaining full street manners. The Grand National’s sinister blackout styling, GN-specific trim and suspension, and driver-focused interior created a discreet yet purpose-built performance package that resonated far beyond traditional muscle-car circles, attracting high-profile owners including Jay Leno and many others. Today, the Grand National is recognised as a landmark performance icon and one of the most collectible modern American muscle cars of its era.
