The Ram TRX – powered by a supercharged 6.2-litre Hemi V8 (523kW/882Nm) which delivers a real-world 0 to 100km/h acceleration time of 4.5 seconds despite weighing close to three tonnes – is heading to the car park in the sky.

Although the electric Ford F-150 Lightning has quicker acceleration, the Ram TRX was the high point in terms of outright performance for V8 petrol-powered US pick-ups – and now it marks the end of an era.

The Ram TRX combined epic supercharged V8 grunt with heightened off-road ability – whereas the Ford F-150 Lightning is effectively a luxury SUV with a ute tray on the back.

Due to its might and breadth of capability, the Ram TRX is almost certain to become a future classic.

The Ram 1500 V8 range is about to be replaced by an updated model with six-cylinder power, and even the flagship of the fleet – the iconic Ram TRX – has succumbed to global pressure to downsize engines.

The updated Ram 1500’s imminent switch to six-cylinder power – which is expected to arrive in Australia early next year after going on sale in the US later this year – will leave the Chevrolet Silverado 1500 (6.2-litre petrol) and 2500 (6.6-litre diesel) as the only V8s in the US pick-up segment in Australia.

The Ford F-150 sold here has twin-turbo V6 petrol power, and the Toyota Tundra will have twin-turbo V6 petrol power paired to a hybrid system when it goes on sale locally next year after an extended trial of 300 vehicles in the hands of VIP customers.

To commemorate the end of an era – and after about 750 sales here of the regular RAM TRX over the past two years – Ram Trucks Australia has introduced the Ram TRX Final Edition.

Out of 4000 Ram TRX Final Editions to be built in the US, just 130 examples are coming to Australia, priced from $249,950 plus on-road costs – about $20,000 dearer than the standard model (of which only 30 remain in stock nationally).

The Ram 1500 Final Edition is only available in three new and unique colours (apologies to fans of black, grey, silver or white): Delmonico Red, Night Edge Blue and Harvest Sunrise (whatever that means, but here are the colours below).

There is no extra power (and frankly, it doesn’t need it) but it does get a list of other goodies.

  • Satin Titanium bead-lock capable wheels with a matching 6.2-litre hood badge and ute bed decal;
