“I find I'm enjoying a lot of the "extra" features I thought were unnecessary. The new model does sit a bit too high for me but I'm getting used to it as well.”
2015 Chevrolet Suburban: What's New, Specs & Features
Last updated August 4, 2026
The 2015 Chevrolet Suburban is a full redesign and the first year of its 12th generation. Its biggest change is an all-new body and cabin paired with a new 355-hp 5.3-liter V8.
About the 2015 Chevrolet Suburban
12th generation, first year of the 2015-2020 design.
Chevrolet positioned the 2015 Suburban as a full-size SUV for active families and anyone who needs maximum passenger space, cargo room, and towing ability in one vehicle. Its core appeal is straightforward: real truck-based capability, a strong V8, lots of room behind the third row, and a quieter, more useful cabin than before. Compared with large crossovers, the Suburban leans harder into heavy-duty hauling, long-trip comfort, and trailer work.
The redesigned Suburban remained a large family and towing vehicle, but its quieter cabin, fold-flat rear seats, and updated controls made it easier to live with. LS covered the family essentials, LT emphasized comfort with heated leather seats, Bose audio, and a power liftgate, and LTZ added an adaptive suspension, heated and cooled front seats, and a power-folding third row. Commercial focused on fleet duty with bench seating and built-in trailering equipment.
What changed, by category
Powertrain
A new 5.3-liter EcoTec3 V8 and six-speed automatic went into every trim. Output rose from 320 hp and 335 lb-ft of torque to 355 hp and 383 lb-ft, while fuel-economy estimates increased from 15 city/21 highway mpg to 16/23.
Styling
Chevrolet introduced an all-new exterior body and a fully redesigned cabin with updated controls, more interior storage, and better noise isolation.
Safety
The new-generation package brought a rearview camera and rear parking sensors. LT featured forward-collision and lane-departure warnings plus a vibrating driver-alert seat, while LTZ added blind-spot, lane-change, and rear cross-traffic alerts.
Tech
The redesigned LT featured Bluetooth audio streaming, five USB ports, Bose audio, and a programmable power liftgate. LTZ gained keyless entry with push-button start and a 10-speaker Bose surround-sound system. On LT, navigation, the touchscreen monitor, and fog lights were optional rather than standard.
Structural
The new long-body shell brought fold-flat second- and third-row seating, electric power steering, and four-wheel disc brakes. Maximum cargo capacity measured 121.1 cubic feet, compared with 137.4 cubic feet for 2014.

“Love the Chevrolet brand. My family for several generations have been Chevy people”
“2015 Chevy Suburban is a work of art. The only negative is: put the plastic back on the center of the rear window so finger prints don't show when shutting the hatch/glass (like the 07-14).”
