When the team at CarExpert in Australia lines up two very different performance machines, you know something outrageous is about to happen. But this one? This was pure madness — a 1,200-horsepower Ram 1500 TRX tuned by Dontex Performance squaring off against the sleek and savage Aston Martin DBX707.
This wasn’t a battle between rivals. It was a heavyweight mismatch on paper — an American sledgehammer versus a British broadsword — and that’s exactly why it had to happen.
The Ram: Turning “Too Much” Into “Not Enough” –
The stock Ram TRX is already a monster, with a supercharged 6.2-liter HEMI® HELLCAT V8 making 702 horsepower (523 kW) and 650 lb-ft (882 Nm) of torque. But Dontex Performance doesn’t do “stock.” They strapped on twin turbos to work alongside the factory supercharger, cranking output to a staggering 1,200 horsepower (over 880 kW).
This thing doesn’t just pull — it tears at the horizon. At over 6,800 lbs (3,080+ kg), it’s far from a featherweight, and its aerodynamics are about as graceful as a brick wall. But point it straight, put drag radials on it, and the TRX turns into a blunt-force weapon.
The Aston: British Brawn In A Tailored Suit –
The Aston Martin DBX707 is the fastest SUV the British brand has ever built, and it’s not shy about flexing. Powered by a twin-turbo 4.0-liter V8 from Mercedes-AMG, this tuned version gets new ball-bearing turbos, sharper engine mapping, and a wet-clutch gearbox. The result? 697 horsepower (520 kW) and 664 lb-ft (900 Nm).
At around 5,260 lbs (2,385 kg), the DBX707 carries a big weight advantage over the TRX — about 1,540 lbs (700 kg)lighter — and it cuts through the air like, well, something that’s not a giant pickup. On paper, it’s a 0–100 km/h (0–62 mph) in just over three seconds kind of SUV.
The Weather: Not Cooperating –
The race went down at a regional airport runway. The problem? Mother Nature wasn’t on the guest list. The surface stayed damp, forcing both drivers to launch on a less-than-ideal strip. That meant traction was precious, mistakes were costly, and horsepower could be as much a liability as an advantage.
The Showdown –
First Pass: The Aston’s launch control tripped over itself, bogging hard. The TRX thundered away for an easy win.
Second Pass: The DBX707 hooked better, but this was the Ram’s house now. The Dontex-tuned beast simply overwhelmed the Aston, pulling ahead early and never looking back. Even with the weight penalty and barn-door aerodynamics, that tidal wave of horsepower was too much to overcome.
This wasn’t just a win for the TRX — it was domination. Yes, the Aston is the more polished, more aerodynamic, and far more civilized machine. But in a straight-line fight, with an overbuilt American V8 howling through a mix of supercharged and twin-turbo boost, the outcome was never really in doubt.
