The Evolution of the Isuzu i-Series Trucks
The Isuzu i-Series trucks represent a significant chapter in the history of compact pickup trucks in North America. Launched with the aim of providing a versatile, durable, and efficient alternative in the small truck segment, the i-Series was produced from 2006 to 2008. Over its brief lifespan, the model line offered various configurations and trim levels designed to appeal to a broad spectrum of consumers—from work-oriented buyers to those seeking a reliable daily driver. This article explores the development, models, and trim levels of the Isuzu i-Series trucks throughout their production years.
Origins and Development
Isuzu Motors, a Japanese automotive manufacturer renowned for its commercial vehicles and diesel engines, entered the North American compact pickup market with the i-Series in 2006. The trucks were built on the GM/Toyota joint-developed GMT-355 platform, sharing much of their underpinnings with the Chevrolet Colorado and GMC Canyon, as well as the Suzuki Equator, which was introduced later.
The primary motivation behind the i-Series was to offer a rugged, compact truck that could serve both work and leisure purposes, filling a niche that had been largely abandoned by major automakers in the early 2000s. Isuzu’s focus on durability, combined with competitive pricing and a range of configurations, aimed to carve out a niche in a segment that valued practicality and reliability.
The production of the Isuzu i-Series commenced in 2006 and concluded in 2008, marking a relatively short run. Despite its brief lifespan, the truck gained a reputation for solid build quality, especially in its diesel variants.
