Isuzu Commercial Truck announced today that the B10 durability rating of its 4HK1-TC diesel engine has been increased to 375,000 miles. The announcement this morning at the National Truck Equipment Association’s (NTEA) 2017 Work Truck Show in Indianapolis.

A B10-life 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 letter ‘B’ indicates the percentage of an engine’s population that will require an overhaul before the indicated mileage.

That means that 90 percent of Isuzu 4HK1-TC engines are expected to last 375,000 miles before they require a major repair or rebuild.

“We are proud to say that Isuzu diesel engines are already known worldwide for their long-term dependability,” said Shaun Skinner, president of Isuzu Commercial Truck of America. “Our new B-10 rating is strong evidence that our engines are even more durable than ever.”

Previously, the 4HK1-TC engine carried an already-robust B10 durability rating of 310,000 miles.

The turbocharged, intercooled 4HK1-TC four-cylinder diesel engine displaces 5.2 liters and generates 215 horsepower. Torque ratings vary depending on model.

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.
