The rumored 2015 Grand National's design features a turbocharged 2.0-liter four-cylinder engine or an optional 3.6-liter V6 engine. The turbocharged inline-four engine produces 272 horsepower, while the V6 creates 321 horsepower. A special GNX model, available only in black, adds twin-turbo aspiration to the 3.6-liter V6 to generate 400 horsepower. Turbo engine models include a manual transmission option.

The Buick Grand National was released in 1982 and named after NASCAR's Winston Cup Grand National Series. The Grand National was produced from the Buick Regal, equipping this sport coupe with a 125-horsepower 4.1-liter V6 engine. A small percentage of the 1982 Grand Nationals feature a turbocharged 3.8-liter V6, generating 175 horsepower and 275 pounds of torque per foot. This turbocharged engine is standard in later model-year Grand Nationals. The last year for production of the Buick Grand National was 1987. This limited GNX model adds a Garrett T-3 turbocharger, large-capacity intercooler, low-restriction exhaust and Turbo-Hydramatic 200-4R transmission. The 1987 GNX cranks out 245 horsepower and 60 pounds of torque per foot. In 1987, the GNX was released only in black.
