Grand-National

The Buick Grand National is a high-performance muscle car that stands apart from other cars on the road. It has an impressive pedigree, offering the legendary Buick turbocharged engine along with several upgrades from the base model. From the moment you take it for a spin, you know that this car has power.

For those wanting to take it one step further, performance chips can make a dramatic difference. A chip installed in a Buick Grand National will boost horsepower and torque. The car’s power will also increase its fuel efficiency. For example, the 1984 Grand National’s 3.8-liter engine could go from 170 horsepower to 245 horsepower after installation of a chip. This improvement impacts acceleration as well, and provides drivers with the speed they desire.

The Buick Grand National came in two models, the coupe and the convertible. Both models had distinctive and classic lines, complete with iconic side striping and three spoke wheels. Drivers found these models of the Buick Grand National to have power and excellent handling on the road. Both the coupe and convertible versions of the Buick Grand National also boasted a modern look and appeal, a big plus for anyone looking for a timeless and impressive car.

Performance chips can enhance a Grand National and give it the edge needed to go fast. Adding a performance chip will instantly increase torque and horsepower while also increasing fuel mileage. The result will be a smoother ride with the potential to go fast, without the use of unnecessary fuel. Installing a performance chip on a Buick Grand National can truly make it an exceptional car and allow you to have an exceptional experience.

In the end, the Buick Grand National was a true muscle car classic. Whether you are driving the coupe or the convertible model, installing a performance chip can enhance its power, torque, and fuel efficiency, so that you can have the drive of your life.
