Spec’ing Fundamentals: Mack Powertrain Basics

Customers invest in a truck for performance, fuel efficiency, uptime, and operating cost. Powertrain decisions drive all of it. In this course, you will explore how Mack powertrain components work together, from engine performance and transmission strategy to axle ratios and tire selection. You will see how each decision impacts performance, efficiency, and durability, building the confidence to spec complete powertrain configurations aligned to real-world customer applications.
After completing this course, you will be able to:

  • Explain how key powertrain components work together to transfer torque from the engine to the road.
  • Describe the relationship between torque, RPM, and horsepower and how they impact truck performance.
  • Identify how transmission selection and rear axle ratio influence cruise RPM, fuel efficiency, and startability.
  • Explain how torque strategy affects driveline stress, axle requirements, and long-term durability.
  • Evaluate how tire selection and axle ratio impact performance at the ground level.
  • Confidently spec a complete, application-aligned powertrain configuration based on customer operating conditions and priorities.
