Really Haul

The 2007 MBE 4000 is sure to give other drivers on the road a severe case of engine-envy. The innovative cast iron block helps make this engine the lightest heavy-duty application diesel on the road—that means you save the weight for payload, not hauling around an overweight engine.

  • Up to 1650 lb-ft Torque
  •  12.8L Displacement
  • Up to580Braking Horsepower

Performance in Action

Take a look at some of the ways the MBE 4000 has become one of the best performing lightweight heavy-duty application engine on the road:

Power to Pull

With 12.8L of displacement in a trim 2,270 pound package, the MBE 4000 has the most acceleration power in its class. With extra torque at low RPM you'll have the power you need for steep grades on long hauls or stop-and-go traffic in severe applications.

Power to Stop

Peace of mind comes standard on the MBE 4000—our standard, integrated engine brake offers you 370 BHP and doesn't add weight to your engine. Need more? The Premium Engine brake boosts your braking power and control to 580 BHP—that's more horses than the MBE 4000's maximum output.

SMART Fuel System

The MBE 4000 features the reliable SMART Fuel System for better performance and improved fuel economy. The DDEC VI controlled high-pressure dual solenoid injectors provide are capable of multiple injections per combustion cycle for better performance and perfect fuel control.

DDEC VI Electronic Controls

Advanced DDEC VI electronic controls give you precise control over all systems in your engine at all times. Sophisticated diagnostics and analytics allow the DDEC VI system to monitor and report any changes in your rig's operation so you can react.

New In 2007

The new 2007 MBE 4000 puts several new key features under your hood, including an enhanced Exhaust Gas Recirculation (EGR) system. And the new DDEC VI electronic controls provide better complete engine management and diagnostic capabilities. Talk about innovative.
