Introduction: A Legacy of Reliability and Performance

For decades, Isuzu Trucks have been trusted by fleets and independent operators around the world.
Known for durability, low maintenance, and excellent fuel economy, Isuzu’s line-up—from the Elf (N-Series) to the Forward (F-Series) and Giga (heavy-duty)—has evolved significantly since the 1990s.

In this article, we compare Isuzu trucks from the 1990s with modern-day models, revealing how advances in technology, safety, comfort, and environmental performance have shaped today’s commercial vehicles.
