Our drag racing series has fired up again and this time we’re bringing out the heavy hitters. Going up head-to-head this time around is a twin-turbo supercharged 1200hp RAM TRX up against the go fast Aston Martin DBX707.
We need to give a massive shoutout to our mates at eBay for helping us cover the cost of putting this event on. It’s an incredibly expensive undertaking and none of this would be possible without their support.

The cars
1200hp RAM TRX
Tuned by Dontex Performance, this RAM TRX is not only supercharged, but twin-turbocharged. It makes around 1200hp (over 880kW of power) and we’ve fitted the car with drag radials to ensure it gets some form of traction. But, while it makes around 1200hp, it’s both heavy and not very aero efficient. So this will be a close one!
Before the Dontex mods, the RAM TRX uses a 6.2-litre supercharged V8 engine that produces 523kW of power and 882Nm of torque.
Aston Martin DBX707
In the opposite corner is the Aston Martin DBX707. This is the new super fast version of the DBX. While it’s still powered by the same 4.0-litre twin-turbocharged V8 engine from Mercedes-AMG, there are new ball-bearing turbochargers, revised engine calibration and wet-clutch automatic transmission.
Outputs increase to 707PS (520kW of power and 900Nm of torque), up by 116kW of power and 200Nm of torque. With an official 0-100km/h time of just over 3.0 seconds it should be enough to keep pace with the TRX.
The results
The weather didn’t play ball with us for this drag race. We waited as long as we could for our regional airport runway to dry out but had to pull the trigger on the drag race while the runway surface was still a bit wet.
Our first run had the Aston Martin’s launch control system bog down massively, so it was an easy win for the TRX. Next time around it hooked up properly, but was still slaughtered by the TRX. Even though the TRX has almost double the power, it weighs around 700kg more than the Aston and becomes significantly more inefficient the faster it goes due to its frontal surface area.
It also sounds absolutely insane under full throttle. While the Aston Martin DBX707 still sounds great, this is on another level entirely.
