The Crew Motorfest - 1987 Buick GNX | Customization and Gameplay 

It actually is. Quite a desired retro classic.

The GNX is awesome, love the turbo that goes through the hood, only if they add a Foxbody Mustang, because that goes with the GNX

Good is an understatement. This thing was a rocket ship that took the entire high-performance automotive industry in the US by storm, managing to piss off GM executives due to its performance, blatantly overshadowing cars within the GM lineup that theoretically shouldn't be able to, and even scaring some European sports cars at the time. All in one! Picture Buick, a company mostly known for its big, comfy, and sluggish saloon cars aimed at older folks. Between 1981 and 1982, the Grand National model began to have quite a winning streak in NASCAR, and the idea of making a sportier version for a younger and more passionate public grew stronger. Then, all of a sudden, a wild V6 turbocharged Buick pushing 200-ish HP and 400 Nm of torque appeared in 1984. People were still reluctant (after all, going for a V6 instead of a V8 seemed like heresy), but it began getting accepted once it started decimating newer Camaros, even beating C4 Corvettes. Safe to say GM didn't like this one bit, telling Buick that by 1988 they must switch to a FWD platform focusing more on luxury and a lot less on performance. Buick decided to give one final middle finger to GM and sent the remaining Grand Nationals to McLaren Performance Technologies for one final edition: the GNX. McLaren worked their magic by giving it the full treatment to elevate its capabilities to a whole new level; new intercooler, improved intake, heads, new exhaust, bigger turbo, reinforced automatic transmission, upgraded differential, suspension overhaul (this included a redesign of its architecture with stiffer shocks), larger and more rigid stabilizer bars, among other enhancements. The result was a 276 HP and 488 Nm machine (as listed by Buick, although it was an open secret that these were underrated performance figures, the car was actually closer to 300 HP and +500 Nm). The GNX was a monster capable of keeping up with a Lamborghini Countach in a straight line! Quoting the actual Car and Driver review from 1987: _"The last Grand National we tested generated some impressive numbers. It ran to 60 mph in 4.9 seconds and clicked through the quarter-mile in 13.9 seconds at 98 mph. The GNX, with 55 more horses and an additional 25 pounds of mass, rockets to 60 in 4.7 seconds and squirts through the quarter-mile in 13.5 seconds at 102 mph. In zero-to-60 performance, the only car available in the U.S. that matches the Buick is the Callaway Twin-Turbo Corvette, and the only one that beats it is the Porsche 911 Turbo, at 4.6 seconds."_
