Mack MD Series medium-duty trucks, both diesel and electric models, are getting a “significant refresh,” according to the company, with a larger cab and new safety features.

These 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 Mack MD cab is now 4 inches longer than the previous version, giving drivers more seat recline and leg room.

Mack noted that 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 interior features premium satin aluminum trim, improved seating with lumbar support, and enhanced LED lighting.

New steering wheel controls for cruise control, telephone and audio functions have been added, increasing driver convenience and safety.

Safety and Body Builder Features on Refreshed Mack MD

Mack MD trucks now come standard with several enhanced safety features, including:

  • A new antilock braking system with automatic traction control

  • Radio mute in reverse

  • Park brake alarm

Pre-wired body builder connections, a relocated air dryer, and wheelbases updated 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.

“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,” said Jonathan Randall, president of Mack Trucks North America.

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). 

The MD Series is a popular choice for various applications, including dry van/refrigerated, stake/flatbed, dump truck and tank truck vocations.

The MD6 model does not require a Commercial Driver's License (CDL) to operate for non-hazardous payloads.
