In celebration of 50 years of Isuzu engines supporting businesses across North America, Isuzu Diesel proudly announces the winners of the Isuzu Quest, a North America–wide competition recognizing legendary Isuzu engines that continue to deliver reliable performance after decades of service.
Launched in September, the Isuzu Quest competition invited customers and Isuzu Diesel distributors to identify the oldest engine still in service and also the longest-running engine based on total operating hours. The response showcased the enduring legacy and remarkable durability of Isuzu engines in the field.
"These engines tell a powerful story about durability," said Kim Murray, director, PT operations and marketing, Isuzu Motors America LLC. "Just as important, they reflect the critical role our distributors and dealers play in helping customers maintain and support their equipment over time. Longevity like this is the result of quality engineering, knowledgeable service and long-term support."
