Driving fuel efficiency

Mack delivers cutting edge solutions that drive both fuel saving and sustainability across its product line. According to Kevin West, senior product manager for vehicle propulsion for Mack Trucks, “whether it’s diesel or electric, regional or vocational, Mack is committed to helping fleets reduce costs and operate sustainably. The new Mack® Pioneer™ sets the standard in fuel efficiency, while maximizing performance.

1. The Mack Pioneer is Mack’s most fuel-efficient highway truck ever. Designed for long-haul and regional carriers, it delivers:

• Industry-leading aerodynamics with an updated cab design, hood, mirrors, and chassis fairings
• Advanced MP 13 series engine and mDRIVE transmission for optimal gear selection and fuel efficiency
• Predictive Cruise Control that adjusts gear selection strategy based on terrain

📣 Coming soon: Pioneer Electric – Mack’s first zero-emission, battery-electric tractor for highway applications will deliver long-haul performance with zero tailpipe emissions.

2. Medium-Duty – Mack MD Series
   The MD Series is built for local delivery, box truck, and service applications. Fuel-saving features include:

• Optimized Allison® automatic transmissions
• Lightweight frames for better MPG
• Efficient Cummins B6.7 engine
• The MD Electric eliminates diesel fuel use entirely, offering a zero-emission powertrain that incorporates regenerative braking

3. Vocational – Mack Granite, TerraPro, and LR Models
   Tough jobs don’t have to mean high fuel costs. Mack’s vocational lineup balances strength with smart efficiency:

• MP engines tuned for low-speed, high-torque performance—ideal for fuel savings in demanding environments
• Idle-reduction technology for urban and stop-start cycles
• The LR Electric for refuse applications removes diesel fuel costs entirely and offers quiet, efficient operations with lower maintenance

4. Electric Lineup – MD Electric & LR Electric with Pioneer EV Coming Soon
   Mack’s growing electric fleet is built to meet environmental goals and reduce operating costs:

• Zero tailpipe emissions
• Regenerative braking that recaptures kinetic energy
• Lower energy cost per mile than diesel
• Significant reduction in maintenance costs due to fewer moving parts

Mack is also investing in charging infrastructure and nationwide service support to ensure a seamless electric transition for fleets. 

FUEL-SAVING FEATURES ACROSS THE MACK LINEUP
1. Mack MP engines
Mack’s MP engines feature advanced combustion technology and a wave piston design that improves fuel efficiency without compromising power. Turbo compounding technology captures waste energy and turns it into usable horsepower—maximizing every drop of diesel.

2. mDRIVE
Standard across most of our highway and vocational lineup, the mDRIVE, automatic transmission learns how you drive and automatically selects the gear that delivers the best fuel economy. When paired with predictive cruise, fuel savings grow mile by mile.

3. Mack Command Steer
Fewer corrections, more control. This driver-assist technology cuts steering effort by up to 85%, helping reduce fatigue and improve smooth, consistent operation—key to optimal fuel use in stop-and-go or tight urban settings.

4. Aerodynamic Enhancements
From the Pioneer to the Mack MD Series, every truck benefits from wind-tunnel-tested features like roof fairings, chassis skirts, bumper spoilers, and side deflectors—delivering better fuel efficiency at highway speeds.

5. Mack Connect + GuardDog® Telematics
Data-driven decisions cut waste. Monitor idle times, route efficiency, and driver behavior in real time. Use insights from Mack Connect to fine-tune operations and save fuel across your fleet.

SIDEBAR: HOW FUEL ECONOMY BOOSTS YOUR BOTTOM LINE
📉 Cost Savings

• 1 MPG improvement = up to $7,000 saved annually per truck
• Across 50 trucks? That's $350,000 per year

🧰 Lower maintenance and increased uptime
Fuel-efficient trucks and EVs reduce engine wear, filter changes, and fluid needs while reducing costly downtime

♻️ Meets emissions targets and ESG goals
Fuel economy = lower carbon footprint, helping your fleet comply with regulations and satisfy sustainability-minded customers

🔍 Telematics
With Mack Connect, monitor idle time, driver behavior, and route efficiency—often improving MPG by 8–10%
With fuel costs representing a significant portion of fleet operating expenses, Mack Trucks is dedicated to delivering best-in-class fuel efficiency while incorporating sustainable solutions into every vehicle we build."
