Isuzu Motors has been thoroughly improving the potentials of diesel engines which have a structural advantage of thermal efficiency and making an in-depth analysis of the vehicle use. We have developed D-Core series engines, which are smaller yet more powerful and cleaner next generation highly-efficient diesel engines.

The engine of the main types of the ELF released in 2006 was downsized from 4.8L to 3.0L at a stroke. With the D-Core series engines, we were successful in improving fuel economy, payload, noise and vibration without sacrificing dynamic performances. Downsizing has been steadily advancing at Isuzu as our trucks comply with Japan's Post New Long-term Emissions Regulations. The GIGA heavy-duty truck has changed its engine displacement from 15.7L to 9.8L, and the FORWARD medium-duty truck from 7.8L to 5.2L.

The D-Core series engines extract the maximum potential out of the vehicles in combination with the most suitable devices and controls. For the Tokyo Motor Show, we have a full lineup of five D-Core series engines on display whose displacements range from 3.0L to 15.7L.

In recent years, there has been a growing interest in alternative energy to oil. It is and will be our mission to support transportation as it was yesterday no matter how drastic the fuel and energy conversion may be. Since 1997, Isuzu has sold 15,000 CNG-powered ELF, FORWARD, and ERGA buses. In addition, we are now developing a vehicle that uses dimethly ether.

As regards hybrid vehicles, we added the ELF hybrid truck that uses lithium-ion batteries to our product lineup in 2005. This time, we put an ELF plug-in hybrid truck on display for reference exhibit. It has a larger battery capacity and higher motor output. As this plug-in hybrid truck, AC100V for home use can be used for battery recharging in case of emergency.

A route bus always drives along a fixed route and frequently repeats stop-and-go cycles. A motor can effectively assist the engine that drives a bus in this application. An ERGA hybrid bus is on display for the Tokyo Motor Show. This is the first display of this model in public.

Safety is an important theme for supporting transportation. "VAT," which is an advanced visual support technology, fully uses highly accurate milliwave radars and sensors to provide a visual early warning against an accident to a driver to support his cognition, decision and operation. "IESC," an electronic vehicle stability control system keeps a stable vehicle position and contributes to danger avoidance. Please enjoy watching these systems on display and a new GIGA tractor equipped with the systems.
