Hino Trucks has introduced a new Class 4 and 5 cab-over diesel electric hybrid truck model for the North American market.  The 155h is a Class 4 model based on the 155 standard diesel (14,500lb GVWR) and the 195h is based on the 195 diesel (19,500lb GVWR).

All four models (hybrids and standards) use the Hino J05E Series engine, a 5.0L 210hp plant with 440lb-ft of torque (597Nm).  The trucks also use the Aisin A465 6-speed automatic transmission and the hybrids use a nickel-metal hydride (NiMH) battery pack.

The hybrids use a Hybrid Adaptive Control System (HACS) to communicate with the Engine Control Unit (ECU) to optimize the truck’s fuel economy and performance according to current load, road conditions, and driver requests (acceleration, coasting, etc).

Both the hybrids and non-hybrids meet EPA 2010 standards for emissions.

Major differences between the Japanese and European models of the 155h and 195h are in the size and frame.  A 33-inch standard North American frame rail width is used on the 56,900psi frame and the fuel tanks are center mounted at rear.  The wider frame means a bigger cab, whose top has been raised to accommodate drivers up to 6.5 feet in height comfortably.  A crew cab version is coming soon.

The diesel models of the 155 and 195 will be available in August and the hybrid will begin entering North American markets in December.

Hino developed the world’s first hybrid bus in 1991 and is Toyota’s heavy truck nameplate.
