Mack Trucks has announced what it calls a significant refresh of its Mack MD Series diesel and electric medium-duty trucks. The new MD features a larger cab that improves the driver environment and incorporates new safety features.

“The launch of the refreshed Mack MD Series once again demonstrates Mack’s commitment to delivering the best medium-duty truck for our customers,” said Jonathan Randall, president of Mack Trucks North America. “Since the MD Series was introduced in 2020, Mack has continued to listen to our customers and make ongoing improvements to meet their operational needs.

Available in Class 6 or Class 7

The Mack MD Series is available with diesel or electric drivetrain options in the MD6, a Class 6 model with a gross vehicle weight rating (GVWR) of 25,995 pounds, and the MD7, a Class 7 model with a GVWR of 33,000 pounds. Both models are exempt from the 12% Federal Excise Tax (FET).

Most Significant Mack MD Updates

Key updates – now standard on the MD without raising its price – include enhanced driver comfort and safety features, while improving ease of installation for body builders.

The biggest change is that the MD's cab is now 4 inches longer than the previous version and provides drivers with more seat recline and leg room.

This refreshed cab further shows how the Mack Anthem cab influenced the MD cab design and many of the shared driver-comfort features, such as an overhead console for additional storage.

The new interior also features:

• Premium satin aluminum trim

• Improved seating with lumbar support

• Enhanced LED lighting

• New steering wheel controls for cruise control, telephone, and audio functions

The trucks now come standard with several enhanced safety features including new ABS (Anti-Lock Braking System) with ATC (Automatic Traction Control), radio mute in reverse, and a park brake alarm.

Pre-wired body builder connections relocated air dryer and updated wheelbases to industry-standard Cab to Axle (CA) dimensions make the updated MD Series easier to install an even wider array of body installations than previously.

Mack MD6 Does Not Require CDL

The MD Series is a leading choice for various applications, including dry van/refrigerated, stake/flatbed, dump, and tank truck vocations. The MD6 model does not require a commercial driver's license (CDL) to operate for non-hazardous payloads.

"The MD Series continues to build on the success of our initial medium-duty offering,” Randall said. “Built with Mack’s heritage of reliability, these enhancements will provide a more versatile and efficient truck, across a wide range of applications.”
