In 1987, Buick decided to conclude the production of the Regal Grand National model, which had been produced since 1984. It was released in a limited series with a sole purpose – to draw the audience’s attention to the company’s achievements in creating muscle cars. The last version of the model, named the Buick GNX 1987, was produced by ASC/McLaren, specializing in turbocharging, at a plant in Los Angeles.
ASC, commissioned by Buick, equipped the vehicles with Garrett AiResearch ceramic turbines and intercoolers with Bosch electronic control. As a result, the parameters looked impressive compared to other exclusive cars.
The heart of the Buick GNX was a 3.8-liter 6-cylinder V-shaped engine, similar to the classic Grand National, but thanks to optimization, the power increased from 245 to 280 hp, and minor modifications allowed it to increase to 300 hp and above.
The car accelerated from 0 to 60 mph in 4.7 seconds. This is a world-class indicator for a car with a medium-sized power unit. 547 copies rolled off the assembly line, most of which are now in the caring hands of classic car enthusiasts.
