Sterling Trucks 2004 Engine Line-up Includes Mercedes-Benz, Detroit Diesel and Caterpillar

LOUISVILLE, KENTUCKY…Sterling Truck Corporation announces the availability of new 2004 engines from Mercedes-Benz, Detroit Diesel, and Caterpillar. Providing outstanding performance, fuel economy and electronic capabilities, the comprehensive line of powerful engines is now available for the wide variety of Sterling models and applications. Sterling exhibited its range of 2004 engines here at the Mid-America Trucking Show.

“In 2004, Sterling continues to offer a wide variety of engine options to meet our customers’ diverse operations,” said John Merrifield, Senior Vice President, Sales and Marketing for Sterling Truck Corporation.


Sterling Trucks offers the Mercedes-Benz MBE900 engine for medium-duty applications, and the Mercedes-Benz MBE4000 engine for on-highway and vocational applications. The lightweight and powerful Mercedes-Benz engines are designed to meet the tough demands of the North American market and feature excellent performance, fuel economy, technology, durability, and low operating cost.

The 2004 MBE900 and MBE4000 engines provide several capabilities that improve truck performance and increase driver satisfaction. Increased fuel economy features such as air-to-air charge cooling with a matched turbocharger, electronically-controlled high-pressure injector pumps, and data logging to monitor fuel consumption are standard. The engines also have an available power take-off (PTO) adaptation option, and leading power-to-weight ratios, which allows for increased payload and a lower operating cost. By using an Exhaust Gas Recirculation system (EGR), the engines meet the 2004 EPA emission regulations without requiring additional aftertreatment devices.

In addition, both engines offer a state-of-the-art electronic control system that allows the engine to be customized to a specific application for maximum efficiency. The technology optimizes fuel injection, diagnoses problems on the fly, monitors oil pressure and coolant levels, and protects the engine from damage with an automatic shutdown. The electronic system also assists in fleet management by offering data collection and sharing, and reports on performance and fuel economy.

Mercedes-Benz MBE900

With more than 300,000 engines in service worldwide, the MBE900 is available in 4- and 6-cylinder configurations with horsepower ratings up to 330 and torque ratings up to 800 lb.-ft. The medium-duty engine, available in 4.8-, 6.4- and 7.2-liter displacements, provides maximum power at a minimum weight and maintains a high torque at a lower RPM for better drivability and fewer shifts. A combination of high-pressure fuel injection systems and a responsive turbocharger eliminate throttle lag and improve fuel economy.

Additionally, the MBE900 features an electronically controlled cooling fan, and the optional compression brake provides excellent engine braking horsepower for the most demanding applications. The engine comes with a 3-year, 150,000 mile base warranty for on-highway applications; and a 5-year, 150,000 mile base warranty for fire, RV and rescue applications.

Mercedes-Benz MBE4000

Designed for on-highway and vocational applications, the Mercedes-Benz MBE4000 is one of the strongest and lightest engines in its class. The engine comes standard with an exhaust brake and produces additional horsepower when combined with the optional Turbo Brake. Additionally, both the standard exhaust brake and optional Turbo Brake are quieter than typical engine brakes and can often be used where others are prohibited.

The lightweight 12.8-liter engine uses advanced materials and components for an excellent power-to-weight ratio, which allows for a greater payload and increased efficiency. Six-unit injection pumps are driven from the new camshaft for an accurate injection control, four valves per cylinder allow the engine to breathe better, and a single cylinder air compressor uses less horsepower. In addition, the MBE4000 comes with a full 2-year, unlimited mileage warranty for truck applications.

Detroit Diesel

Available on Sterling’s L-Line and A-Line models, the Detroit Diesel 2004 Series 60 engine offers customers an excellent combination of a popular and proven product that is fully certified to the new emissions standards. The latest Series 60 engines features include improved performance, efficiency, and electronic capabilities.

To meet the latest emissions regulations, the Series 60 is equipped with EGR, and does not require an aftertreatment device of any kind or any changes in usual maintenance procedures. The engine offers several performance features including an EGR cooler with a lightweight tube-in-shell design for improved efficiency, and a new Electronic Fuel Injector for faster response time and increased durability. A variable geometry turbocharger provides better fuel economy while improving drivability and engine braking.

In addition, the 12.7- and 14.0-liter Series 60 features a new DDEC V electronic control for increased capability and reliability, which provides additional microprocessor power, four-times more memory, and 150 output pins versus the current 81. Also new in the 2004 Series 60 is the one-piece (Monotherm) piston with a closed oil gallery for better cooling and more durability.
