Freightliner Truck has unveiled several changes to its 2004 line-up, including two EGR engines for medium and heavy-duty trucks, an AGS transmission for its Business Class M2 vehicles, a new look for the Century Class S/T and a new interior for both the Century Class S/T and the Columbia.

The Mercedes-Benz MBE4000 and MBE900 diesel engines for Freightliner heavy- and medium-duty trucks are built to meet upcoming 2004 emissions standards, using an Exhaust Gas Recirculation (EGR) system).

The 12.8 litre MBE4000 is a heavy-duty engine that can be used for regional distribution, vocation, truckload and bulk-haul applications. It’s offered in the Century Class S/T and the Columbia, as well as in heavier-duty Business Class M2 vehicles.

The 4.3-through 7.2 litre engine MBE900 is for use in medium-duty truck applications including distribution, food and beverage delivery, towing, utilities and fire and emergency service. The engine is offered in Freightliner Business Class M2 vehicles.

Both engines combine electronic controls, fuel injection and extended maintenance cycles.

The MBE4000 delivers high torque at low RPM. It develops 90% of its peak torque at 1,000 RPM, which reduces shifting while increasing acceleration and gradeability. The high-output turbocharger is matched with high-pressure injectors for better driveability, fuel economy and low emission output. The horsepower ranges from 350-450 hp and the torque ranges from 1350 to 1550 lb ft.

MBE900 diesel engines are available in four- and six-cylinder configurations and offer 170 to 330 hp and torque range from 420 to 1,000 lb. ft. The range of torque is delivered at a low RPM allowing for fewer, smoother shifts, better driveability and more capacity to climb hills and negotiate stop and go traffic.
