2023 Chevrolet Silverado 1500 — Pickup Buyer’s Guide
Documented scope: MY2023; United States. Do not transplant this market’s specifications to another region.
2023 scope and confirmed powertrain
The US 2023 Silverado 1500 brochure documents an updated second-generation 3.0-litre Duramax turbo-diesel rated at 305 horsepower and 495 lb-ft. Other engine choices include a 2.7-litre turbo four-cylinder rated at 310 horsepower, a 5.3-litre V8 rated at 355 horsepower and a 6.2-litre V8 rated at 420 horsepower. These powertrains have different transmissions and configuration-dependent tow ratings.
What defines this 2023 vehicle
The genuinely relevant MY2023 change is the revised diesel, which Chevrolet describes as increasing power and torque over the predecessor. This follows an earlier mid-cycle refresh; it is not a wholly new Silverado platform. Grade names from work-oriented WT through luxury High Country describe significant cabin and equipment differences, not new generations.
Who should consider it
A used full-size pickup should be selected from its payload sticker, hitch arrangement, cab and bed configuration before its appearance. Someone who mainly carries tools and commutes may prefer a different engine and grade from someone repeatedly towing heavy trailers. Factory headline maximums apply only to specific configurations and do not guarantee the same allowance on every truck.
A particularly important buying distinction
The diesel update is important because older model-year comparison tables can contain the previous 3.0-litre output. A used shopper should check engine code and year before comparing 2023 diesel listings. The same discipline applies to advertised towing: a published maximum attached to one axle ratio or equipment group must not be assumed on another configuration.
Checking a used example in 2026
Inspect frame and bed condition, signs of towing overload, brake and tyre condition and evidence of correct maintenance for the fitted engine. Diesel buyers should evaluate emissions-system service and local operating suitability through specialists, without assuming a universal repair problem. Verify recalls and build specification by VIN, particularly if imported.
Alternatives and the decision
Alternatives include a Ford F-150 or Ram 1500 with comparable cab/engine and tow equipment. For smaller occasional loads, a mid-size Colorado or Ford Ranger can reduce daily size penalties. The 2023 Silverado’s revised diesel is its sharpest year-specific research reason.
