Chevrolet announced on Nov. 29 that the 2025 Tahoe and Suburban launch late next year, available in LS, LT, RST, Z71, Premier, and High Country trims, with a more powerful diesel engine option available later in production, and new technology enhancements.

“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 in a recent news release. “Our segment-leading position is the envy of our competitors — no one comes close to Chevrolet.”

Diesel Engine Specs

The second-generation 3.0L inline-six turbo-diesel Duramax offers more power for trailering. It is paired with a 10-speed automatic transmission and is offered on all retail trims, including Z71 for the first time.

Launched previously on the Silverado 1500, the new diesel engine is rated at 305 horsepower and 495 lb-ft of peak torque, increases of 10% and 7.6%, respectively, over the current diesel engine’s 277 horsepower and 460 lb-ft of torque.

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, while new sound absorption materials and a tuned air induction system help balance its performance with quietness and improved refinement.

A 5.3L gas V-8 remains the standard engine for LS, LT, RST, Z71, and Premier. The 6.2L V-8 is standard on High Country and available on RST, Z71, and Premier. The new diesel engine will be available in 2025 after its initial launch.

Fuel Tank Capacity

  • Tahoe: 24 gal. / 91 liters (2WD & 4WD)
  • Suburban: 28 gal. / 106 liters (2WD & 4WD)

Ride-and-Handling Refinements

The multilink independent rear suspension design introduced on the current Tahoe and Suburban has been updated to provide better ride-and-handling dynamics.

“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.”

Additionally, air ride adaptive suspension and magnetic ride control return as available features.

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. With this, it helps reduce pitch, body roll, and vibrations that can resonate in a large SUV.

Towing Capability

A max trailering package is available, and on select trims, the package includes a high-capacity radiator and cooling fan, an integrated trailer brake controller, hitch view, hill decent control, and blind zone steering assist with trailering.

Tahoe and Suburban will also introduce the following new and enhanced features:

  • Trailer Tire Health - prevents trailer tire blowouts with a trailer tire life monitor and over-speed warning.
  • Mobile Trailering App Load Rating Info - offers anytime/anywhere access to the vehicle’s load rating.
  • Forward Path Indication - 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 – customers can access a checklist and step-by-step instructions to prepare for towing, launching, and retrieving a boat, which is newly available within the trailering app.
  • Trailer Navigation - can calculate routes based on trailer size using built-in Google Maps.

The 2025 Tahoe continues to offer a max towing range of 8,400 lbs and the Suburban offers 8,200 lbs.

Safety and Technology

The 2025 Tahoe and Suburban now feature a new sensor that can detect certain types of motion in the vehicle, which can help identify if a passenger has been left in the rear passenger areas of the vehicle.  

“We want to help families by introducing a feature that may help them remember their precious cargo in the back seats,” explains Tricia Morrow, head of Global Safety Technology Strategy at GM. “This feature is a testament to GM’s commitment to developing innovative safety technology.”

Interior Motion Detection may detect certain types of micro-movements in the cabin. If movement is detected in the vehicle while in park and turned off, it can progressively escalate alerts to help raise awareness.

Connected cameras comprise a fully integrated network of cameras that allow customers to remotely view the interior and exterior of their vehicle, including 360-degree views of the exterior.

Key benefits include automatic crash recording, security recording, live view, my recordings (dash cam functionality), industry-first cloud storage, etc.. Camera views and recordings are accessible via the myChevrolet mobile app.

Some features require an appropriate OnStar plan. 

Tahoe and Suburban will continue to offer the standard suite of safety features and driver assistance technologies that include:

  • Enhanced Automatic Emergency Braking
  • Forward Collision Alert
  • Lane Keep Assist with Lane Departure Warning
  • Front Pedestrian and Bicyclist Braking
  • IntelliBeam.
  • Enhanced Automatic Parking Assist
  • HD Surround Vision
  • Teen Driver
  • Buckle to Drive

Additional safety and driver convenience technology highlights include Super Cruise and AutoSense Power Liftgate. Super Cruise is a hands-free driving driver assistance technology available on more than 400,000 miles of roads in the U.S. and Canada, that will be available in 2025 after initial launch. AutoSense Power Liftgate is a feature which makes loading a Tahoe or Suburban easier when the user’s arms are full by automatically opening the liftgate when it senses the key fob behind the vehicle.

The 2025 Tahoe and Suburban are connected by OnStar to elevate the in-vehicle experience with a variety of available safety, entertainment, and convenience features, including Super Cruise functionality, 24/7 access to live OnStar advisors, on-demand vehicle diagnostics, HD streaming, and more.

Tech-Focused interior

Display screens are the centerpiece of the cabin, starting with an all-new standard 17.7-inch-diagonal infotainment screen paired with the 11-inch-diagonal driver information center.

Additional interior highlights include a redesigned center console with new storage options and a repositioned wireless charging pad, as well as a new steering wheel design.

Production and Assembly

Production will take place at GM’s Arlington Assembly plant, in Texas. Announced earlier this year, GM is investing more than $500 million in the Texas facility to strengthen its industry-leading full-size SUV business.

Through this investment, Arlington Assembly will receive new tooling and equipment in its stamping, body shop, and general assembly areas.
