The roar of a Pontiac engine often brings to mind powerful V8s. But there's another engine that played a significant role in Pontiac's history: the GM 60° V6. Introduced in 1980, this engine offered a blend of power and efficiency, making it a versatile choice for a variety of Pontiac models. This article explores the history of this engine and the Pontiac cars it powered.The 60° V6 debuted in GM's X-body cars, including the Pontiac Phoenix. Initially, it was a 2.8-liter engine producing around 115 horsepower. This engine provided a good balance for these smaller cars, offering enough pep while still being relatively fuel-efficient. According to SlashGear, this engine was a key part of GM's strategy to offer more economical options.As the 60° V6 gained popularity, it found its way into other Pontiac models, including the 6000. This mid-size car benefited from the engine's balance of power and efficiency. A high-output version, delivering 135 horsepower, was available for sportier models like the 6000 STE. This showcased the engine's adaptability to different performance needs. Hemmings describes this high-output version as a key selling point for these sportier models.The engine continued to evolve. Later versions increased in size, with displacements reaching 3.1 and even 3.4 liters. The Pontiac Grand Prix, a more performance-oriented model, also utilized the 60° V6. The Grand Prix even featured a turbocharged version of the 3.1-liter V6, boosting horsepower to 205. This demonstrated the engine's potential for higher performance applications.One common question is how reliable these engines were. Generally, the GM 60° V6 is considered a durable and reliable engine. Millions were produced and used in various GM vehicles, suggesting a solid track record. Another question is how these V6s compared to Pontiac's V8s.
