With its production run spanning four decades, and eight generations, the Pontiac Grand Prix was among the GM-owned carmaker's most popular vehicles. For most of the decade after its 1962 introduction, Pontiac positioned the Grand Prix as a full-size performance coupe. Over successive generations, however, the car would undergo several transformational changes, culminating in it eventually becoming a four-door sedan by the time its production run ended in 2008. Well over a decade since the last Pontiac Grand Prix rolled out of the assembly lines, the car is still very much in demand — especially the older variants of the car dating back to the '60s and '70s.

What Engine Is In A 1989 Pontiac Grand Prix & How Much Horsepower Does It Have?

The 5.9L Cummins diesel engine is best known for its time when it powered Dodge trucks beginning in 1989, and it's an engine that certainly helped propel the Ram into being one of the top pickup truck brands. If you're looking to get as much performance as possible out of 5.9L Cummins diesel, then you need to set your sights on the latest iteration of the engine that you can find. For the first several years, there's no difference in performance as the engine produced 160 horsepower and 400 lb-ft of torque from 1989 to 1993.

Slapping through the gears while winding out the engine is a thrilling experience, and nothing launches a 426 Street Hemi off the line like a four-speed. Now that trucks have become daily drivers and even luxury vehicles, they mostly have automatics, but manual transmissions used to be the standard in pickups.

There is a perception that a V-patern engine is better in terms of performance and efficiency, but the reality is a straight-six has so many advantages over its V-6 cousin. An inline engine only needs one head, gets by with half the cam shafts, and is easier to cool. I-6 engines also produce more torque at lower speeds and are perfectly balanced, making them quieter with less vibrations. Most importantly, a straight-six is cheaper to manufacture.

The only manual V8 RWD sedan left in America is a compelling proposition all on its own; the Cadillac CT5-V Blackwing is a reminder of what AMG used to be, and after being refreshed for 2025 with new looks and a 33-inch touchscreen, it's on par with German automakers in the interior tech department. The 2025 CT5-V Blackwing didn't get any performance enhancements when it was revealed at the beginning of this year, and we didn't think it needed any, but now Cadillac has addressed the issue with a new Precision Package that promises enhanced handling for all driving conditions.

The Dodge Challenger, a relatively latecomer to the muscle car scene, debuted in 1970. However, its reign as a performance icon was short-lived. Chrysler’s decision to discontinue high-compression big-block engines in 1971 effectively ended the Challenger’s muscle car era. While production continued until 1974 with smaller powerplants, it’s the early, potent models that command the highest collector interest.
