Therefore, there is no announced official interior design for the GNX 2026 model. However, designers and enthusiasts envision a high-end, high-tech cabin that combines modern comfort with subtle references to the original vehicle’s heritage. These meticulously designed interiors often feature black leather with red accents and bold textures, mirroring the original black and gray interior with red gauges.

A key modern feature is a large, digital display that often serves as both the instrument panel and infotainment center; some ideas mention a 30-inch curved OLED screen or a 50-inch panoramic augmented reality display, reflecting Buick’s current design philosophy in models like the Envision and Enclave. Other features designed include wireless charging, ambient LED lighting, and advanced driver assistance systems, creating a modern and refined ambiance.
2026 Buick Grand National : Engine
Powered by these concept engines, the 2026 Buick Grand National features a powerful 3.6L twin-turbocharged V6 engine with outputs ranging from approximately 450 to 550 horsepower. This option is often touted as the first V6 engine to be supported by a drivetrain. For the high-performance GNX, a larger 6.2L LT4 V8, borrowed from other GM performance vehicles and producing over 650 horsepower, is also a popular choice among digital designers. These engines are engineered with modern performance features such as improved engine management, enhanced cooling systems, and optional all-wheel-drive systems, and will deliver significantly higher performance than the original car.

The original 1987 Buick Grand National and the limited-edition GNX were powered by a heavily modified, turbocharged 3.8-liter V6 engine. While the standard Grand National produced 245 horsepower and 355 lb-ft of torque, the GNX, developed in partnership with McLaren Performance Technologies, had an official figure of 276 horsepower and 360 lb-ft of torque. Independent testing at the time indicated that actual output often approached or exceeded 300 horsepower, making the GNX faster than many modern V8 sports cars, including the Chevrolet Corvette and Ferrari models.
