Isuzu says its Class 5 FRR low cab-forward tilt model, which is powered by a 7.1-liter diesel engine, offers the same reliability as heavier models. Its turbocharged, intercooled power plant delivers 200 horsepower at 2,500 rpm. Other new features in the FRR include improved engine cooling, a redesigned electronic fuel-control system, and a wider load platform for easier body installation.

The Class 6 FSR offers a GVWR of 23,100 pounds and a 200-hp. Isuzu 6HE1-TC diesel engine. Routine engine maintenance now can be performed without tilting the cab, but for more complicated repairs, operators can tilt the cab to 45 degrees. The heavier-weight Class 7 FTR and FVR, with GVWRs of 30,000 and 33,000 pounds respectively, also include the 200- and 230-hp. 6HE1-TC engines. Six-speed manual overdrive transmissions are standard, but buyers may specify optional Allison automatic transmissions.

Also new this year is Isuzu's L-Series diesel engine, which the manufacturer says is easier to maintain, quieter, and produces lower emissions than its predecessor. The compact, lightweight 3LB1 and 3LD1 models meet both current and future emissions-control regulations. Rated at 30 and 40 horsepower respectively, they offer better reliability, easier maintenance, and longer life than other lightweight engines, says Isuzu.
