Chevrolet Suburban

2026 CHEVROLET SUBURBAN RST 4WD — UNITED STATES SPECIFICATION

ENGINE AND DRIVETRAIN

This car carries the optional EcoTec3 6.2-litre L87 V8 in place of the 5.3-litre V8 standard on the grade. It is a naturally-aspirated overhead-valve 16-valve engine of 6,162 cc with spark-ignition direct injection, Dynamic Fuel Management variable cylinder deactivation and variable valve timing, rated by Chevrolet at 420 hp (313 kW) and 624 Nm (460 lb-ft). Drive reaches all four wheels through a Hydra-Matic 10-speed automatic transmission with Electronic Precision Shift, on a 3.23 axle ratio. A Heavy-Duty Trailering Package with an auxiliary transmission fluid cooler and engine oil cooler is standard equipment on the Suburban.

CHASSIS, STEERING AND BRAKES

Body-on-frame construction with independent front suspension and — the defining change of this generation of the full-size Chevrolet SUV — a fully independent multi-link rear suspension in place of the live rear axle used through 2020. Steering is electric power-assisted rack and pinion. Braking is four-wheel disc with anti-lock, supported by StabiliTrak electronic stability control with traction control, Hill Start Assist, Tow/Haul Mode Grade Braking and an automatic electric parking brake.

DIMENSIONS AND CAPACITIES

Overall length 5,748 mm (226.3 in); overall width excluding mirrors 2,060 mm (81.1 in); wheelbase 3,406 mm (134.1 in). Fuel tank 106 litres (28.0 US gallons). Cargo volume is 1,175 litres (41.5 cu ft) behind the third row, 2,657 litres (93.8 cu ft) behind the second row and 4,094 litres (144.6 cu ft) maximum with the second and third rows folded. Overall height, kerb weight and ground clearance are deliberately omitted: Chevrolet publishes no single figure for this configuration and the sources consulted did not agree, so no number is recorded rather than an estimated one.

TOWING AND CAPABILITY

Per the 2026 Chevrolet Trailering Guide, maximum trailer weight for a Suburban 4WD with the 6.2-litre V8 is 7,300 lb (3,311 kg) on a Gross Combination Weight Rating of 14,000 lb; with the optional Max Trailering Package those figures become 7,800 lb (3,538 kg) and 14,500 lb. This car is fitted with a factory tow hitch and seven-pin trailer wiring, but the Max Trailering Package is not confirmed, so the lower rating is the one to plan against. Trailer tongue weight should be 10 to 15 per cent of loaded trailer weight, to a maximum of 1,250 lb. Gross Vehicle Weight Rating is not published by Chevrolet per configuration — it appears only on the vehicle's own certification label — and is therefore not recorded.

EXTERIOR

RST is the monochromatic street-appearance grade of the Suburban range, substituting body-colour and gloss-black exterior detailing for the chrome used elsewhere in the line-up, with black Chevrolet bowtie emblems front and rear, a black mesh grille and dark-finish alloy wheels. This car is finished in Black. Lighting is LED front and rear with IntelliBeam automatic high-beam control. A dual-pane tilt-sliding power panoramic sunroof with power sunshade, rain-sensing wipers, heated power-adjustable mirrors with integrated turn signals and puddle lamps, assist steps, roof rails and a power liftgate are fitted.

INTERIOR AND SEATING

Three rows in a seven-seat layout: two front buckets, two second-row power-release bucket seats with a centre walk-through to the third row, and a 60/40 split-folding third-row bench. Upholstery is leather-appointed in Jet Black with Victory Red accent stitching, carried across the seats, steering wheel and door trim. Heated front seats, a heated wrapped steering wheel, driver memory settings, tri-zone automatic climate control, a power-sliding centre console with drawer, a cargo management system and two 120-volt power outlets are fitted.

INFOTAINMENT AND CONNECTIVITY

A 17.7-inch diagonal colour touchscreen running Google built-in with embedded navigation, paired with an 11-inch diagonal reconfigurable Driver Information Centre. Wireless Apple CarPlay and Android Auto, in-vehicle Wi-Fi hotspot capability, embedded OnStar hardware, Bluetooth, four USB ports and two further charge-only ports in the third row.

DRIVER ASSISTANCE AND SAFETY

Chevrolet Safety Assist and the wider standard suite comprise Adaptive Cruise Control, Enhanced Automatic Emergency Braking, Forward Collision Alert, Front Pedestrian and Bicyclist Braking, Intersection Automatic Emergency Braking, Lane Keep Assist with Lane Departure Warning, Blind Zone Steering Assist, Rear Cross Traffic Braking, Rear Pedestrian Alert, Reverse Automatic Braking, Side Bicyclist Alert, Safety Alert Seat, HD Surround Vision, Enhanced Automatic Parking Assist, Hitch Guidance, IntelliBeam, Buckle to Drive and a Tire Pressure Monitoring System with Tire Fill Alert. Airbag protection covers all three rows via roof-rail side curtains.

FUEL ECONOMY

EPA ratings for this configuration are 14 mpg city and 18 mpg highway (approximately 16.8 and 13.1 litres per 100 km). No verified homologated CO2 figure exists for this vehicle in a destination-market test cycle, so none is recorded.
