The b18 engine was designed with the demands of large vehicles in mind. Its 6.2-liter V8 configuration provides the substantial torque and power characteristics that drivers often seek in full-size pickup trucks and SUVs. General Motors used the engine in several vehicles, including versions of the Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, and GMC Yukon XL. These vehicles are commonly used for family transportation, long-distance driving, carrying heavy loads, and towing.
