Gutsy Performance
The turbocharged, intercooled, dry sleeved in-line 6 cylinder MD230 Diesel engine is the heart of the UD TRUCK. With 230 horsepower and 506 pound-feet of torque, the engine delivers gutsy performance in stop-and-go city routes and during longer range interstate trips. The MD230's balanced powertrain also produces excellent startability.
The MD230 and a tuned intake/exhaust system result in optimum fuel economy. The air compressor and power steering pump are gear driven for greater reliability, while a single V-rib poly belt operates the water pump, fan clutch/fan, and alternator.
Because protecting our environment is a top priority for the Nissan Diesel Motor Company, the MD230 meets all current EPA Emissions Standards and California Air Resource Board Requirements. The 24 valve engine design, along with a high pressure, common rail fuel injection system and exhaust gas recirculation (EGR) technology combine to make the MD230 one of the cleanest commercial truck engines available today.
Putting Horses to Work
Harnessing the power of the MD230 are transmissions specifically designed to optimize the engine's strengths and payload requirements. For manual transmission applications, the U1800HD to UD3300 are equipped with the MLS63B, 6-speed overdrive. Allison automatic transmissions are available in the UD1800HD to UD3300. The 1000RDS automatic is optional in the UD1800HD and the UD2000. The 1000RDS automatic is optional in the UD2300LP, UD2300DH and the UD2600. The 2500RDS automatic is available only on the UD3300.
