The 2025 Chevrolet Tahoe offers three engine choices to match a variety of driving needs. Standard options include a 355-horsepower 5.3-liter V-8 and a more powerful 420-horsepower 6.2-liter V-8, both paired with a smooth-shifting 10-speed automatic transmission. Rear-wheel drive comes standard, with all-wheel drive available for added traction.

For those seeking efficiency and torque, the available 3.0-liter diesel inline-six now generates 305 horsepower and a hefty 495 pound-feet of torque. This engine also uses the 10-speed automatic and is offered across all trim levels.

The off-road-focused Tahoe Z71 adds serious capability with a two-speed transfer case, all-terrain tires on 20-inch wheels, and underbody skid plates. It also features an available air suspension system that can raise or lower the vehicle's ride height for better ground clearance or easier loading. This adjustable suspension is also offered on RST and High Country models.

The new Tahoe offers impressive towing power alongside spacious seating for up to eight passengers—or nine with the available front bench seat. When equipped with rear-wheel drive and the standard 5.3-liter V-8 engine, the Tahoe can tow up to 8,400 pounds, rivaling some full-size pickup trucks. Opting for the more powerful 6.2-liter V-8 lowers the maximum towing capacity slightly to 8,300 pounds, while models with the diesel engine can tow up to 8,200 pounds.

The EPA hasn’t published fuel economy estimates for the 2025 Chevrolet Tahoe yet, but they’re likely similar to last year’s ratings. In 2024, the diesel-powered Tahoe was the most fuel-efficient, earning 21 mpg in the city and 28 mpg on the highway. The standard 5.3-liter V-8 offered slightly better city fuel economy than the optional 6.2-liter V-8, though both engines were rated up to 20 mpg on the highway.
