1984 Camaro (Third Generation, F-body):
* Design: Sharp, angular styling, often described as "boxy." More wedge-shaped than its predecessor. Used the same body platform as the Pontiac Firebird.
* Platform: GM's F-body platform (shared with the Firebird). This platform was considered quite robust for its time.
* Engines: Offered a range of V6 and V8 engines, including the legendary 5.0L small-block V8 (which was improved and upgraded throughout the third generation) and various other smaller displacement V8 and V6 engines.
* Technology: Technology was relatively basic for the time. Power options were available, but advanced electronics were scarce.
* Size and Weight: Generally larger and heavier than later models.
1991 Camaro (Third Generation, F-body - but a later iteration):
* Design: While still based on the same F-body platform, the 1991 Camaro had received a significant facelift from the 1984 model. It featured a more rounded, aerodynamic body style. The front fascia and rear-end were substantially different.
* Platform: Still the F-body platform, but with several refinements and improvements over the earlier years of the third generation.
* Engines: Engine choices were still available, but with refinements and improvements to the existing V6 and V8 offerings. The 5.7L (350 cubic inch) V8 remained a popular choice, though power outputs likely differed from the 1984 models, and fuel injection was standard.
* Technology: Some advancements in technology might be present, though it remained relatively basic in comparison to modern vehicles. Improved fuel injection systems and some optional electronic features were likely added since 1984.
* Size and Weight: Likely more refined and slightly smaller in some dimensions due to design changes, potentially resulting in a slightly lower weight, though this may be minimal.
In short: The 1991 Camaro was a later, refined version of the same third-generation platform as the 1984 model. However, the styling changes, some mechanical refinements, and potential technological advancements made it a significantly different driving and ownership experience. The 1984 model had a more angular, boxy look, while the 1991 model sported a more rounded and aerodynamic shape. Both, however, shared the same fundamental platform. A 1991 Camaro is a far cry from a fourth-generation (1993-2002) Camaro.
