Profile: Detroit Diesel Corp. does the entire process - from design and manufacturing, to sales and service. The engines include Series 60 - that gives the perfect balance of power and fuel efficiency for heavy-duty applications; MBE 4000 - powerful acceleration, and braking power to match in a lightweight and durable package; MBE 900 - for medium-duty and vocational applications such as fire, emergency and RV. Our transmissions, MBT manual and automated gearshift (AGS) transmissions provide smoother shifting, lighter weight for maximum payloads and increased fuel efficiency. The axles, proprietary front, single rear and tandem rear axles bridge American and European technology. Using the same design platform as European and Latin American axles, our innovative axle systems provide an excellent cost-to-performance ratio for the commercial truck market. These axles are precisely designed to match the performance of our transmissions and engines.
