Detroit Diesel vs. Caterpillar: Diesel’s Greatest Rivalry

Описание: For over two decades, Detroit Diesel and Caterpillar waged the fiercest rivalry in American trucking history. This documentary breaks down the battle between Detroit’s high-tech, fuel-efficient Series 60 and Caterpillar’s legendary 3406E and C15 — engines known for brute strength and unshakable durability. It’s a story of philosophy, not just horsepower: smart evolution vs. mechanical tradition.

We dive deep into the origins of the Series 60 and its groundbreaking DDEC system, the first fully integrated electronic engine management platform in a long-haul diesel. On the other side, Caterpillar refined its proven 3406 platform with MEUI injectors and ADEM controls, giving drivers massive torque with field-repairable simplicity. From fleet dominance to owner-operator loyalty, each engine carved out a loyal following that shaped the culture of American trucking.

But emissions regulations changed everything. In 2007, the EPA’s new diesel standards forced both companies to adapt. Detroit leaned into its digital roots and evolved, while Caterpillar refused to compromise its core values — ultimately walking away from the on-highway engine business. This is the untold story of how technology, regulation, and driver loyalty collided in one of diesel history’s greatest rivalries.
