OE Spotlight: 2025 Suburban And Tahoe Both Get Duramax Power

In what many will feel is great news, Chevrolet just announced that the 2025 Suburban and Tahoe will launch late next year with fresh designs inside and out, a more powerful diesel engine, and new technology.

“The updates on the 2025 Chevy Tahoe and Suburban make the industry’s best-selling full-size SUVs an ever-stronger option for our customers,” said Scott Bell, vice president, of Chevrolet. “Our segment-leading position is the envy of our competitors — no one comes close to Chevrolet.”

2025 Suburban And Tahoe Get A New Look

The 2025 Suburban and Tahoe feature a new look, framed by a fresh front-end design that’s distinguished with new, bolder lighting. All six trims — LS, LT, RST, Z71, Premier, and High Country — receive a new front fascia, with select trims offering unique design cues. The Z71 incorporates skid plates and a high-approach front fascia, while the High Country leans in on a sport-luxury theme, with a sophisticated balance of black and Galvano chrome trim.

“The new faces of Tahoe and Suburban are more expressive, borrowing inspiration from the recently refreshed Chevrolet truck lineup,” said Phil Zak, executive design director, of Global Chevrolet. “They remain as versatile as ever, but with a greater emphasis on the details that have driven these large SUVs to the top of their segment.”

Comfort And Technology Are Included

Inside, a new interior design is centered around an all-new 17.7-inch-diagonal central touchscreen, along with an enhanced High Country interior and additional refinements across the lineup. The new Tahoe and Suburban feel airier and more spacious, with a revamped interior that emulates a technology focus. Sweeping lines and a lowered instrument panel increase the perceived space for the driver and front-row passenger.

The display screens are the centerpiece of the cabin, starting with an all-new standard 17.7-inch-diagonal freeform infotainment screen paired with the 11-inch-diagonal driver information center. The “big” screen is canted slightly toward the driver, prioritizing easy access for the front-seat passenger.

2025 Suburban And Tahoe Get Duramax

Also new is the second-generation 3.0-liter inline-six turbo-diesel Duramax. This next-gen engine offers more power, particularly when trailering. It is paired with a 10-speed automatic transmission and is offered on all retail trims, including Z71.

Previously launched in the Silverado 1500, the new diesel engine is rated at 305 horsepower and 495 lb-ft of peak torque. These are increases of 10 percent and 7.6 percent, respectively, over the current diesel engine’s 277 horsepower and 460 lb-ft of torque.

Towing capacities for 2025 Suburban and Tahoe come in at 8,200 pounds and Suburban offers 8,400 pounds respectively.

A retuned turbo compressor, along with new, higher-flow fuel injectors, revised piston-cooling oil jets, new steel pistons, and improved temperature control features with the cooling system’s Active Thermal Management contributes to the engine’s enhanced power.

Enhanced safety and technology include a fully integrated network of cameras that allow customers to remotely view the interior and exterior of their vehicle, in addition to recording events like crashes and theft. Some features may require an OnStar plan.

Ride And Handling Are Better Than Ever

Underneath is a multilink independent rear suspension design introduced on the current Tahoe and Suburban which has been updated to provide more refined ride-and-handling dynamics. Additional steering calibration improvements were also made.

“The already excellent ride-and-handling characteristics enabled by the independent rear suspension are taken to the next level with the 2025 Tahoe and Suburban,” said Martin Hayes, chief engineer. “Their responsiveness makes them feel much nimbler than their full-size dimensions suggest.”

The newly available trailering app is shown on the new standard 17.7-inch-diagonal central touchscreen.

The Air Ride Adaptive Suspension is available on High Country and Z71, along with RST. It offers automatic load-leveling and ride-height adjustment. In highway driving, it automatically lowers the ride height to help reduce aerodynamic drag, which can help enhance efficiency. Driver-selectable heights can reduce entry/exit heights when the vehicle is parked, and the driver can also raise the body for additional ground clearance when driving off-road.

With Magnetic Ride Control, which is standard on Premier and High Country and available on RST and Z71, sensors continually “read” the road 1,000 times a second to alter the damping rate of the shocks almost instantly.

2025 Suburban And Tahoe Can Tow With Confidence

The 2025 Suburban and Tahoe will continue to include the trailering technologies from previous years. A Max Trailering package is available, and on select trims, includes a high-capacity radiator and cooling fan, an integrated trailer brake controller, Hitch View, Hill Decent Control, Blind Zone Steering Assist with Trailering, and the Chevrolet Trailering App. Tahoe and Suburban will also introduce the following new and enhanced features:

  • Trailer Tire Health, helps prevent trailer tire blowouts with a trailer tire life monitor and over-speed warning.
  • Mobile Trailering App Load Rating Info, which offers anytime/anywhere access to the vehicle’s load rating.
  • Forward Path Indication, which helps drivers navigate with their trailer with guidelines on the Surround View to indicate the width of the trailer and the trailer’s path. When the turn signal is activated, guidelines will show the driver the estimated turning path for both the vehicle and trailer.
  • Boat Ramp Assist, which helps customers access a checklist and step-by-step instructions to prepare for towing, launching, and retrieving a boat, is newly available within the trailering app.
  • Trailer Navigation, which calculates routes based on trailer size using built-in Google Maps
  • The 2025 Tahoe continues to offer a max towing range of 8,400 pounds and Suburban offers 8,200 pounds.
