GMC has long been a leader in the truck industry, and has produced some of the best-known and most reliable trucks ever made. But did GMC make a semi truck? The answer is yes, they did make a semi truck, but it was only for a few years in the late 1970s and early 1980s.
The semi truck that GMC produced was known as the “General Motors Class 8” (GMC8). It was a large, heavy-duty truck designed to haul heavy loads over long distances.
The engine was a V-8 diesel with an output of up to 400 horsepower. The chassis had an independent suspension system with air brakes, and the cab had air conditioning and power steering.
The GMC8 had two different versions: the standard version and the extended version. The standard version had a wheelbase of 125 inches, while the extended version had a wheelbase of 133 inches. Both versions could be configured with either manual or automatic transmissions, as well as different axle ratios for better fuel economy or higher payload capacity.
Unfortunately, despite its impressive specifications and features, the GMC8 was not successful in the market. It lacked features such as power windows and cruise control that were becoming increasingly popular at the time, and its high price tag put it out of reach for many consumers. As a result, production stopped after only three years in 1983.
Today there are still some GMC8s on the roads, but they are few and far between as most have been retired or scrapped over time due to their age and lack of parts availability. However, they remain an interesting part of GMC’s history that is worth remembering.
In conclusion, GMC did produce a semi truck known as the GMC8 from 1977-1983. Despite its impressive specs and features it failed to sell well due to its high price tag compared to competitors at that time which led to production being discontinued after only three years on the market. Despite this it remains an interesting part of GMC’s history that is worth remembering today.
