Detailed Explanations
1961-1963 (First Generation): Unitized Body Construction, Independent Rear Suspension (IRS), "Rope Drive" Transaxle, Available Four-Cylinder Engine Derived from the Pontiac V8
The first-generation Tempest was groundbreaking for its time, featuring a unitized body construction which provided greater structural rigidity. Its independent rear suspension (IRS) offered improved handling and ride quality compared to traditional solid axles. The most unique feature was the "Rope Drive" transaxle, a flexible driveshaft connecting the front-mounted engine to a rear-mounted transmission. This design aimed to improve weight distribution, but it proved to be a weak point. The four-cylinder engine, essentially half of the Pontiac V8, was economical but lacked the power desired by many drivers.
1961-1963 (First Generation): Rope Drive Prone to Failure, Rear Suspension Complex and Difficult to Repair, Four-Cylinder Engine Lacks Power for Some Drivers
The innovative "Rope Drive" was unfortunately prone to failure due to its complex design and the stresses it endured. Repairing the independent rear suspension could be complex and expensive, requiring specialized knowledge and tools. The four-cylinder engine, while fuel-efficient, often felt underpowered, especially when carrying passengers or cargo.
1962-1963 (LeMans Option): Enhanced Trim and Features Over Base Tempest, Available Bucket Seats, More Powerful Engine Options
The LeMans option offered a touch of luxury and performance compared to the base Tempest. It included enhanced trim, such as upgraded upholstery and exterior brightwork. Bucket seats were available, providing a sportier feel. Crucially, the LeMans offered more powerful engine options, addressing the performance concerns of the base four-cylinder.
1962-1963 (LeMans Option): Shares Same Potential Mechanical Issues as Base Tempest Models
Despite its upgrades, the LeMans shared the same fundamental mechanical components as the base Tempest, meaning it was still susceptible to issues with the Rope Drive, rear suspension, and rust. This is an important consideration when evaluating a potential purchase.
1964-1965 (Second Generation): Conventional Front-Engine, Rear-Wheel-Drive Layout, Available as Tempest, Tempest Custom, and LeMans, Introduction of the Pontiac Overhead Cam (OHC) Six-Cylinder Engine
The second-generation Tempest marked a significant departure from the first generation. It adopted a conventional front-engine, rear-wheel-drive layout, eliminating the problematic Rope Drive. The car was available in various trim levels, including the base Tempest, Tempest Custom, and LeMans. The introduction of the Pontiac Overhead Cam (OHC) six-cylinder engine was a notable innovation, offering a good balance of performance and fuel economy.
1964-1965 (Second Generation): OHC Six-Cylinder Engine Can Be Problematic if Not Properly Maintained, Rust Can Be a Significant Issue, Particularly in Northern Climates
While innovative, the OHC six-cylinder engine could be problematic if not properly maintained. Its complex design required regular valve adjustments and careful attention to lubrication. Rust was a common issue, especially in areas where road salt was used during winter. The Tempest’s body design was susceptible to corrosion in areas like the rocker panels, floorboards, and around the wheel wells.
1966-1967: Styling Updates, Improved Interior Appointments, Continued Availability of OHC Six-Cylinder and V8 Engines
These years saw styling updates that refined the Tempest's appearance. Improved interior appointments enhanced comfort and aesthetics. The OHC six-cylinder engine remained an option, alongside V8 engines for those seeking more power.
1966-1967: OHC Six-Cylinder Engine Still Requires Careful Maintenance, Rust Remains a Concern
The OHC six-cylinder engine continued to demand careful maintenance to avoid potential issues. Rust remained a significant concern, requiring thorough inspection before purchase.
1968-1969: Minor Styling Revisions, Focus Shifts Towards Performance and the LeMans Model, Introduction of the GTO as a Separate Model (Previously a LeMans Option)
These years brought minor styling revisions to keep the Tempest/LeMans looking fresh. The focus shifted towards performance, with the LeMans becoming increasingly popular. A key development was the introduction of the GTO as a separate model. Previously, the GTO was an option package available on the LeMans.
1968-1969: Rust Continues to Be a Potential Problem, Parts Availability Can Be Challenging for Specific Components
Rust remained a potential issue, particularly in older examples. Parts availability could be challenging for certain components, requiring patience and resourcefulness during restoration or repair.
1970: Last Year of the Tempest/LeMans Nameplate, Essentially a Continuation of the 1969 Model
1970 marked the last year of the Tempest/LeMans nameplate. The model year was essentially a continuation of the 1969 model, with minimal changes.
1970: Rust, Limited Parts Availability
Like previous years, rust was a primary concern. Limited parts availability could make restoration and maintenance difficult.
Frequently Asked Questions
