Overview
The 2026 Chevrolet Suburban has been in continuous production since 1935 — the longest-running SUV nameplate in the world. The current T1 generation (2021+) brought IRS, more interior space, and a dramatic cabin redesign.
The Suburban competes with the Ford Expedition MAX, Lincoln Navigator L, and GMC Yukon XL. It typically wins on cargo space and resale value.
No other vehicle nameplate has been in continuous production since 1935. The Suburban has served as presidential transport, police interceptor, military workhorse, and family hauler across 12 generations.

Powertrain
EPA highway rating measured at 55 mph. Real-world highway at 70 mph is typically 18–20 mpg. Towing near max capacity reduces highway fuel economy 30–40% — budget accordingly for trailer trips.
In a Suburban used for long road trips, the diesel saves ~$1,200/year vs the gas V8 at average mileage. Payback period is ~3.5 years over the diesel premium.
The 5.3L V8 (355 hp) is standard. An optional 3.0L Duramax diesel returns 23/26 mpg while maintaining 8,000-lb tow capacity — exceptional for a vehicle this large.
Cargo & Passenger Space
144.7 cu ft of max cargo — more than a Transit passenger van. The Suburban's extended wheelbase is why fleet buyers, large families, and security details choose it over shorter competitors.
The Suburban's 144.7 cubic feet of maximum cargo (all rows folded) exceeds the Expedition MAX and every other non-commercial vehicle on the market. Third-row legroom is class-leading due to the extended wheelbase.
Second-row seats fold flat and third-row power-fold is standard on LT+, making conversion from 9-passenger to full cargo quick and tool-free.
Tech & Features
Available Super Cruise on Suburban covers 400,000+ miles of pre-mapped US/Canada roads — the most extensive hands-free highway system available in any SUV.
A 10.2-inch LVDS touchscreen is standard on LT+. Available rear-seat entertainment (dual 12.6-inch screens), wireless charging, head-up display, and available Super Cruise hands-free driving make it competitive with luxury SUVs.
Reliability
Suburban reliability mirrors the Tahoe — exceptional long-term durability built on GM's proven truck platform. Many Suburbans reach 250,000+ miles in fleet service.
