Reliability runs on experience
With its trusted and proven technology backed by 25+ years of leadership and experience, the 2027 X15™ gives you the confidence to move forward fearlessly.
Better fuel efficiency
Base engine optimizations contribute up to 4% improvement in fuel efficiency while maintaining similar diesel exhaust fluid consumption (vs. the 2024 EPA X15™).
Weight neutral system
A sculpted engine block reduces engine weight and adds strength to the right places, resulting in a weight-neutral system—allowing for maximum payload.
