2022 Chevrolet Silverado price and features: Ram 1500 put on notice by hulking new HD LTZ Premium pick-up with 1234Nm 6.6L turbo-diesel V8

GMSV Australia will add a third variant to its ‘remanufactured’ Chevrolet Silverado line-up in November, with the 4x4 full-size pick-up to become available in an even larger Heavy Duty LTZ Premium version.

The HD LTZ Premium is $30,000 dearer than the ‘regular’ LTZ Premium, at $144,990 plus on-road costs, which also puts plenty of space between it and the entry-level LT Trail Boss variant ($106,990).

Helping to distinguish the HD LTZ Premium is a 6.6-litre Duramax turbo-diesel V8 engine with 332kW of power and 1234Nm of torque. It’s mated to a new 10-speed Alison torque-converter automatic transmission.

For reference, the LT Trail Boss and regular LTZ Premium are instead motivated by a 313kW/624Nm 6.2-litre naturally aspirated petrol V8 engine.

Compared to the rest of the Ram 1500 rival’s range, the HD LTZ Premium only shares its roof panel, with the rest of its body unique due to its increased size. In particular, its tub measures 2104mm long and 1814mm wide, offering 1968L of volume and 12 tie-down points.

To further help the HD LTZ Premium stand out from the crowd, the Silverado’s available Appearance Package is fitted as standard, with it bundling in body-colour bumpers, gloss-black 20-inch alloy wheels and a Chevytec spray-on bed liner as well as black finishes for the skid plate, bonnet vent, tubular side steps, door handles and badging.

Better yet, the Z71 Off-Road Package is also in tow, with it introducing off-road suspension with Rancho twin-tube shocks, hill-descent control and specific branding, while the Advanced Towing Package adds a reversing camera with hitch guidance, an integrated trailer brake controller and power-extendable side mirrors.

Then there’s the Technology & Safety Pack 2, which includes low-speed autonomous emergency braking with pedestrian detection, high-beam assist, blind-spot monitoring, rear cross-traffic alert and front and rear parking sensors.

Other standard equipment includes a power-operated tailgate, a sunroof, an 8.0-inch multifunction display, a 15.0-inch head-up display, a heated steering wheel, heated and cooled front seats, and dual-zone climate control.

According to GMSV Australia, the HD LTZ Premium’s full technical specifications will be released once its certification is finalised around October. In the meantime, registrations of interest are being taken on its website.
