The speed of a 1965 GTO depends heavily on the specific model and modifications. There wasn't one single GTO; options included different engine sizes and transmissions. However, generally speaking, a stock 1965 Pontiac GTO with the top-of-the-line 389 cubic inch V8 could achieve a
0-60 mph time in the low-to-mid 7-second range, and a
quarter-mile time in the low 14-second range. Top speed was likely in the neighborhood of
120-130 mph, but this varied greatly depending on conditions and the driver's skill.
Keep in mind these are estimates based on period testing and are subject to variation. Many examples have been modified over the years, drastically affecting performance.
