2026 CHEVROLET SUBURBAN Z71 4WD — US SPECIFICATION

ENGINE AND DRIVETRAIN

The Z71 is powered by the 5.3-litre EcoTec3 L84 V8, a naturally aspirated 90-degree overhead-valve engine of 5,327 cc with an aluminium block, direct injection, variable valve timing and Dynamic Fuel Management cylinder deactivation. Bore and stroke are 96.0 mm by 92.0 mm on an 11.0:1 compression ratio. Output is 355 horsepower (265 kW) at 5,600 rpm and 383 lb-ft (519 Nm) at 4,100 rpm. Drive is through a 10-speed automatic transmission (GM code MHS) to a four-wheel-drive system with an Autotrac two-speed transfer case, a 3.23:1 rear axle and a mechanical limited-slip rear differential. An external engine oil cooler, an external auxiliary transmission oil cooler, a heavy-duty air filter, a 220-amp alternator and a heavy-duty 730 cold-cranking-amp battery are standard on this grade. The engine runs on E15-capable petrol and carries automatic stop/start with a disable button.

CHASSIS, STEERING AND BRAKES

Front suspension is independent coil-over-shock; the rear is an independent multi-link layout, both on the Premium Smooth Ride tune fitted to the Z71. Steering is power-assisted rack-and-pinion with a manual tilt-and-telescoping column. Braking is by four-wheel antilock discs with Hill Descent Control and trailer sway control. Wheels are 20-inch bright machined and painted Technical Gray aluminium, shod with Goodyear Wrangler Territory all-terrain blackwall tyres. A 17-inch full-size steel spare with an all-season tyre and a carrier is included, along with a mechanical jack and tools.

DIMENSIONS AND CAPACITIES

Overall length is 5,748 mm (226.3 in) on a 3,406 mm (134.1 in) wheelbase, with a body width of 2,057 mm (81.0 in) excluding mirrors and an overall height of 1,933 mm (76.1 in). Curb weight as specified is 2,596 kg (5,723 lb) and the gross vehicle weight rating is 3,493 kg (7,700 lb), giving a maximum payload of 897 kg (1,977 lb). Gross axle weight ratings are 1,724 kg (3,800 lb) front and 1,950 kg (4,300 lb) rear; gross combined weight rating is 6,350 kg (14,000 lb). The fuel tank holds 106 litres (28.0 US gal). Cargo volume is 1,175 litres behind the third row, 2,656 litres behind the second row and 4,092 litres with both rear rows folded.

OFF-ROAD HARDWARE

The Z71 grade adds a high-approach-angle front fascia, front and rear skid plates, red recovery hooks, Hill Descent Control, the Autotrac two-speed transfer case, a mechanical limited-slip rear differential, black tubular assist steps and all-terrain tyres. Chevrolet does not publish a Z71-specific ground clearance, approach angle or departure angle for the Suburban, so none is stated here.

TOWING AND CAPABILITY

Trailering equipment is standard and this unit was ordered with the Max Trailering Package, which adds an integrated trailer brake controller, an enhanced cooling radiator, Blind Zone Steering Assist with Trailering and Hitch View. Hitch Guidance, trailer sway control and the Smart Trailer Integration Indicator are included. The gross combined weight rating of 6,350 kg (14,000 lb) against a 2,596 kg curb weight is the governing figure; Chevrolet's per-style specification table does not publish a maximum trailer weight for this configuration, so none is asserted.

EXTERIOR

Paint is Dark Ash Metallic over body-colour mirror caps and door handles. Lighting is LED throughout — headlamps and tail lamps with animated lighting, front fog lamps and IntelliBeam automatic high-beam control. Glass is acoustic laminated with a solar-absorbing windshield, a windshield shade band and deep-tinted rear glass. Other exterior equipment includes heated power-folding outside mirrors with driver-side auto-dimming, black roof-mounted side rails, a power programmable liftgate, Rainsense automatic wipers, a rear intermittent wiper, upper active aero shutters and a dual-outlet exhaust with dual tips.

INTERIOR AND SEATING

Seating is Gideon / Very Dark Atmosphere leather-appointed. This unit was ordered with power second-row bucket seats, which replace the standard second-row bench and make it a SEVEN-seater rather than the eight-seat standard configuration. The third row is a power-folding bench. Front seats are 8-way power with 2-way power lumbar and are heated, as are the second-row outboard seats and the steering wheel. Driver seat, mirror and column memory settings are fitted. Climate control is tri-zone automatic with rear air conditioning. The cabin also carries a front centre console with covered storage, 120-volt power outlets, bright sill plates, carpeted floor covering and mats, an auto-dimming inside rearview mirror and illuminated visor vanity mirrors.

INFOTAINMENT AND CONNECTIVITY

The centre display is a 17.7-inch diagonal advanced colour LCD with Google built-in compatibility, paired with an 11-inch diagonal colour Driver Information Center. Wireless Apple CarPlay and wireless Android Auto are standard, as are wireless phone charging, SiriusXM with a 360L trial, 5G Wi-Fi hotspot capability, OnStar services capability with eight years of OnStar Basics, Universal Home Remote and USB ports in the front console, centre console and third row. Audio is the Bose CenterPoint Surround 10-speaker system.

DRIVER ASSISTANCE AND SAFETY

Standard driver assistance includes Enhanced Automatic Emergency Braking, Front Pedestrian and Bicyclist Braking, Intersection Automatic Emergency Braking, Forward Collision Alert, enhanced Lane Keep Assist with Lane Departure Warning, Rear Cross Traffic Braking, Reverse Automatic Braking, Rear Pedestrian Alert, Side Bicyclist Alert, Safety Alert Seat, Enhanced Automatic Parking Assist, HD Surround Vision with a rear camera washer, Adaptive Cruise Control and an Interior Camera. Blind Zone Steering Assist with Trailering came with the Max Trailering Package. Passive safety comprises seven airbags including full-length head-curtain protection for all three rows, a front outboard Passenger Sensing System, four-wheel antilock disc brakes, direct tyre-pressure monitoring, Rear Seat Reminder, Teen Driver and Buckle to Drive. The factory window sticker carries the NHTSA Government 5-Star Safety Ratings panel, but the star values are printed as vector glyphs and could not be read from the document, and NHTSA has not published a 2026 Suburban result — so no star rating is claimed.

EMISSIONS NOTE

The tailpipe CO2 figure recorded against this vehicle, 355 g/km, is converted from the US EPA combined-cycle value of 571 grams per mile printed on the factory window sticker. It is a US EPA test-cycle figure and is NOT a WLTP or NEDC homologation number; destinations that assess duty on WLTP CO2 should obtain a local homologation figure rather than rely on this value.
