Why Choose Detroit Powertrain?
Unified Component Design — Detroit uniquely designs and builds the engine, transmission, and axles to operate as a single system, creating unmatched drivetrain harmony.
Intelligent Performance — Features like Intelligent Powertrain Management (IPM10) allow the system to read the terrain ahead and optimize torque, shift points, and fuel use in real time.
Smooth & Efficient Shifting — The DT12® transmission uses GPS-enhanced control along with technologies such as eCoast and IPM to improve shift quality and reduce idle RPM for better fuel economy.
High-Efficiency Axles — Detroit steer and tandem axles are purpose-built to match downsped engines and transmissions, offering faster ratios, reduced friction, and optional lubrication systems (ALM2) that boost efficiency and reduce wear.
Lower Operational Costs — The synergy of Detroit’s powertrain reduces maintenance needs, improves durability, and enhances fuel savings—backed by 24/7 support and a widespread service network.
