Chevrolet Silverado 2024 review: 2500 HD - GVM test

Our test vehicle is available only with GM’s 6.6-litre 'Duramax' turbo-diesel V8, 10-speed automatic transmission and dual-range 4x4 system for a list price of $163,000.

Our example has optional 'Slate Grey' prestige paint ($1250) plus GMSV accessories including a powered roller tonneau cover ($3970) and rear under-seat storage ($455) which adds more than $5600 to the price. So, with on-road costs, it's drive-away is more than $170K.

MY24 upgrades include styling, performance, towing and safety enhancements. There’s also a redesigned interior, with its most notable feature being upsized dash screens comprising a 12.3-inch configurable driver’s info display (paired with a colour head-up display) and larger 13.4-inch multimedia touchscreen. 

There’s also a premium Bose sound system, Apple/Android connectivity and wireless phone-charging, plus USB ports front and rear, dual-zone climate control, heated leather-rimmed steering wheel (with four-way adjustment), a power sunroof and power sliding rear window.

Leather-appointed seating offers 10-way driver and front passenger power adjustment, heated/ventilated front seats, heated rear seats, rear privacy glass, a power tailgate, tubular side-steps, 360-degree camera (and up to 14 different camera views), full LED lighting including fog lamps and DRLs plus heaps more. It’s what you might call fully-loaded - even without a load.

With its towering 3762kg kerb weight, the 2500 HD offers a choice of ADR load ratings (NB1 or NB2) which must be specified by the customer at the time of ordering (at no extra cost) to ensure the correct certification for vehicle registration.

The NB1 category allows up to 4500kg GVM/733kg payload, which can be driven by car licence holders. NB2 allows up to 5148kg GVM/1386kg of payload, but requires a truck licence. Our test vehicle is certified for the lower NB1 rating.

The 2500 HD is rated to tow up to 3500kg of braked trailer with a 50mm ball and up to 4500kg with a 70mm ball. These trailer weights are well within its capabilities, given that its GCM rating (how much it can legally carry and tow at the same time) is an eye-popping 12474kg.

Yep, that’s more than 12 tonnes, which allows for trailers weighing more than 4500kg using heavy-duty connections like pintle hooks, goosenecks/fifth-wheel turntables installed and certified by specialist aftermarket suppliers.

The enormous load tub offers almost 2.0 cubic metres of cargo volume and has large external steps front and rear for easier access. The load floor is 2089mm long, 1814mm wide and 533mm deep, with 1317mm between the rear wheel-housings allowing Aussie or Euro pallets to be carried.

It’s protected by a tough spray-on liner, plus there are 12 load-anchorage points, LED lighting, power tailgate and a camera to keep an eye on loads when driving. Our test vehicle was also fitted with adjustable and removable load-dividers, which are part of the GMSV accessories range.

Cabin storage for driver and front passenger includes two bottle/cupholders and a large bin in each door plus a single glove box. The centre console has a large open tray up front, two bottle/cupholders in the centre and an Esky-sized box at the back with padded lid that doubles as a plush elbow rest.

Rear seat passengers get a bottle/cupholder and bin in each door plus two more bottle/cupholders in the rear of the centre console and another two in the fold-down centre armrest. There are also large storage pockets on both front seat backrests and compartments cleverly hidden behind hinged upper backrest cushions.

The 60/40 split rear seat base can swing up and be stored vertically if more internal load space is required. This also provides access to the under-seat storage accessory fitted to our test vehicle. You’d seriously struggle to run out of cabin storage!

Side-steps and large handles on the A- (and B-) pillars assist climbing aboard. It’s a very comfortable driving position, given the multiple seat and steering wheel adjustments along with plush elbow rests on both sides.

The large door mirrors, combined with numerous camera angles including the central rear view mirror's pin-sharp image, provide commanding all-around vision.

The steering is nicely weighted and surprisingly communicative for such a giant, providing good feel and response at all speeds.

The suspension tuning is supple enough to provide a smooth ride, yet retains enough firmness to minimise the ponderous feel inherent in vehicles of this size and weight.

Braking response is also reassuringly strong, without requiring huge pressure on the brake pedal to achieve it.

The 6.6-litre turbo-diesel V8 and 10-speed auto provide effortless performance. With maximum torque tapped at just 1600rpm, the engine is barely ticking over at city and suburban speeds.

And it requires less than 1500rpm to quietly maintain 110km/h on the highway, which combined with its low tyre and wind noise results in a supremely relaxed long-haul cruiser.

With its NB1 GVM rating, we loaded more than half a tonne into the load tub, which combined with our crew of two was just under its 733kg payload limit.

It simply didn’t notice the added weight, storming up our 13 per cent gradient, 2.0km-long set climb with acceleration unmatched by any loaded vehicle we’ve tested on this ascent.

Its engine-braking on the way down using the exhaust brake also set a new benchmark, never exceeding 50km/h and 2000rpm on overrun without once touching the brake pedal.

The Silverado is covered by a three year/100,000km warranty with three years roadside assist.

Scheduled servicing is every 12 months/12,000km, whichever occurs first, and there's no capped-price servicing. This ownership package falls short compared to rivals like Ford's RHD F-150.
