The Pontiac Tempest, introduced in the early 1960s, was a groundbreaking vehicle that challenged conventional car design. Among its many innovations was its unique 1963 Pontiac Tempest rear suspension, which offered both advantages and limitations.
Innovative Features of the 1963 Pontiac Tempest Rear Suspension
The 1963 Pontiac Tempest rear suspension was a departure from traditional designs. It featured a swing axle, which allowed the rear wheels to move independently of each other, improving handling and stability. This design also eliminated the need for engine mounts, reducing vibrations.
Another innovative feature of the 1963 Pontiac Tempest rear suspension was its transaxle, a combination of the transmission and differential located at the rear of the vehicle. This design improved weight distribution and reduced driveline losses.
Advantages of the 1963 Pontiac Tempest Rear Suspension
The innovative design of the 1963 Pontiac Tempest rear suspension offered several advantages:
Improved handling and stability due to the swing axle design
Reduced vibrations due to the elimination of engine mounts
Better weight distribution and reduced driveline losses due to the transaxle design
Limitations of the 1963 Pontiac Tempest Rear Suspension
Despite its innovative features, the 1963 Pontiac Tempest rear suspension had some limitations:
Jacking up in fast corners: The swing axle design could cause the rear wheels to “jack up” in fast corners, resulting in oversteer and potential loss of control.
Agricultural sound: The four-cylinder engine, despite innovative mounting solutions, produced an unrefined sound.
Penny-pinching: Cost-cutting measures led to the use of a swing axle rear suspension, which was technologically inferior to the double-jointed suspensions used by European manufacturers.
Mitigating the Limitations of the 1963 Pontiac Tempest Rear Suspension
Pontiac addressed some of the limitations of the 1963 Pontiac Tempest rear suspension in later model years. For example, the jacking up issue was partially mitigated in 1963 by modifying the suspension geometry and adding a rear anti-roll bar.
The 1963 Pontiac Tempest’s rear suspension was a bold and innovative design that offered both advantages and limitations. While it provided improved handling and weight distribution, it also had some drawbacks, such as the jacking up issue. Despite these limitations, the Tempest’s rear suspension remains a testament to the creativity and engineering prowess of Pontiac engineers.
FAQ: 1963 Pontiac Tempest Rear Suspension
