The Best Years For Isuzu Impulse And Some To Avoid

The Isuzu Impulse, also known as the Piazza in some markets, was a distinctive and sporty coupe that graced the automotive landscape from the early 1980s to the early 1990s. With its striking design, often attributed to Giorgetto Giugiaro of Italdesign, and available turbocharged engines, the Impulse carved out a niche for itself among enthusiasts. However, like any vehicle, some model years proved to be more reliable and desirable than others, making choosing the right one crucial for potential buyers today.

This guide aims to provide a comprehensive overview of the Isuzu Impulse model years, highlighting the best ones to consider and those that might be best avoided. We'll delve into specific aspects of each generation, including performance, reliability, features, and potential problem areas, empowering you to make an informed decision whether you're a seasoned collector or a newcomer to the world of classic Japanese sports cars.

Detailed Explanations

1983-1984 (First Generation)

The initial run of the Isuzu Impulse captured attention with its sharp, angular design penned by the legendary Giorgetto Giugiaro. These models featured a rear-wheel-drive layout and a 2.0-liter SOHC engine. The handling was considered sporty for its time, offering an engaging driving experience. However, the carbureted engine could be prone to issues, particularly in colder climates or with age. Rust was also a significant concern, especially in areas with harsh winters. Parts availability for these early models is increasingly limited, making repairs more challenging.

1985-1989 (First Generation - Mid Cycle Refresh)

Isuzu addressed some of the early concerns with a mid-cycle refresh. The most significant improvement was the introduction of fuel injection, which improved engine reliability and performance compared to the carburetor-equipped models. The interior also received some minor updates. While the styling remained largely similar, subtle tweaks enhanced the overall appearance. Despite these improvements, rust remained a prevalent issue. The early fuel injection systems, while an upgrade, could still be temperamental compared to modern systems. Sourcing parts, while slightly easier than for the 1983-1984 models, still presents a challenge.

1988-1989 Turbo (First Generation)

For those seeking more performance, the turbocharged version of the first-generation Impulse offered a significant boost in horsepower. These models featured a turbocharged 2.0-liter engine and a sport-tuned suspension for enhanced handling. However, turbocharger maintenance is crucial for longevity, and neglecting this can lead to costly repairs. The potential for higher repair costs is inherent with turbocharged vehicles due to the added complexity. As with all first-generation Impulses, rust remains a concern. These models can be quite desirable among collectors due to their increased power, but finding one in good condition requires patience and diligence.

1990-1993 (Second Generation - Piazza Nero)

The second-generation Isuzu Impulse, known as the Piazza Nero, represented a significant departure from the original. It switched to a front-wheel-drive platform and featured a sleeker, more modern design. The suspension was tuned by Lotus, renowned for their expertise in handling, providing a balanced and engaging driving experience. A turbocharged engine was still available, and some models even offered optional all-wheel drive. However, these models are known for more complex electronics, which can lead to potential electrical issues as the cars age. Finding well-maintained examples can be challenging, as many have suffered from neglect or improper maintenance. The complexity of the second-generation Impulse makes it potentially more expensive to repair and maintain compared to the first generation.

Conclusion

Choosing the best year for an Isuzu Impulse depends on your priorities and tolerance for potential maintenance challenges. The 1985-1989 fuel-injected models offer a good balance of reliability and classic styling, while the turbocharged variants provide a more thrilling driving experience. However, the second-generation Piazza Nero, while more modern, can present more complex maintenance issues. Ultimately, thorough research, careful inspection, and a willingness to address potential problems are key to finding a well-preserved Isuzu Impulse that you can enjoy for years to come.
