* Smooth operation: The even number of cylinders and firing intervals contributed to a notably smoother running engine compared to straight-six or V-8 engines of the time. This was a significant selling point.
* Relatively high power output: For their displacement, they produced good power, enhancing performance compared to smaller engines.
* Torque: They generally produced good torque, which is useful for pulling heavy loads or accelerating smoothly.
However, straight-eights also had some drawbacks:
* Length: Their straight design made them longer than V-8s, impacting the design and packaging of the vehicles they powered.
* Complexity: They were generally more complex and expensive to manufacture than other engine types.
* Weight: They tended to be heavier than comparable V-8 engines.
Buick's straight-eights were a significant part of their brand identity for many years, contributing to the perception of Buick as a maker of refined and powerful automobiles. They eventually gave way to V-8s as manufacturing techniques and design preferences changed.
