Isuzu Commercial Truck of America, Inc., distributor of America鈥檚 best-selling low cab forward trucks, today announced that the B10 durability rating of its 4HK1-TC diesel engine has been increased to 375,000 miles. The company made the announcement today at the National Truck Equipment Association鈥檚 2017 Work Truck Show in Indianapolis.
A 鈥淏10-life鈥� rating is an industry-standard gauge provided by engine makers to help consumers determine the long-term durability of an engine. The number following the 鈥淏鈥� indicates the percentage of an engine鈥檚 population that will require an overhaul before the indicated mileage.聽That means that 90% of Isuzu 4HK1-TC engines are expected to last 375,000 miles before they require a major repair or rebuild.
Previously, the 4HK1-TC engine carried an already-robust B10 durability rating of 310,000 miles.聽鈥淲e are proud to say that Isuzu diesel engines are already known worldwide for their long-term dependability,鈥� said Shaun Skinner, president of Isuzu Commercial Truck of America, Inc. 鈥淥ur new B-10 rating is strong evidence that our engines are even more durable than ever.鈥�
The turbocharged, intercooled 4HK1-TC four-cylinder diesel engine displaces 5.2 liters and generates 215 horsepower. Torque ratings vary depending on model.聽The engine is fitted to Isuzu NPR-HD, NPR-XD, NQR and NRR models, as well as the all-new 2018 Isuzu FTR Class 6 truck. Each of these models is backed by a three-year/unlimited mileage powertrain limited warranty.
