When the Ram 1500 Rebel TRX arrives (hopefully) later this year, it will not be engineered to tear up a quarter mile drag strip. Frankly, I have seen a production TRX completely undisguised and there is no question that it is an off-road performance truck designed to battle the Ford F-150 Raptor. It sits high in the air, it has off-road suspension and it has big, off-road-ready tires. It is just about everything that you don’t want or need in a drag strip truck, but at the end of the day, it is powered by a Hellcat Hemi and it is inevitable that some Mopar lover is going to take their Rebel TRX to the drag strip.

In fact, some members of the modern Mopar community are planning on buying a Hellcat-powered Ram 1500 and they are already talking about taking it to the track. With that in mind, we thought that we would get our minds off of the troubles of the modern world and do some speculation on Rebel TRX quarter mile times.

What We Know

There is no official information on the Ram 1500 Rebel TRX, but thanks to our contacts who are familiar with the project, we have the key details. It will be powered by the supercharged 6.2-liter Hellcat Hemi, offering somewhere in the area of 707 horsepower and 650 lb-ft of torque. It will have an 8-speed automatic transmission and it will have some sort of high strength four-wheel-drive or all-wheel-drive system with off-road suspension and off-road tires. It will be a quad or crew cab style truck with a loaded interior, likely with a short bed. It will also likely have similar high performance Brembo brakes to the systems featured on the Jeep Grand Cherokee Trackhawk.

We don’t know what it might weigh, but in speaking with a group of Ram 1500 Rebel owners , I found that their trucks weigh around 5,800 pounds. To be clear, that is actual scale weight in the real world, not the stated weight from FCA. The TRX will almost certainly be heavier, with the engine, brakes and perhaps the four-wheel-drive systems all being heavier than the components in the current Rebel. There could be some use of lightweight materials to help bring weight down a bit, but we shouldn’t be surprised if the production Ram 1500 Rebel TRX weighs 6,000 pounds. That does not include the spare tire carrier in the bed or the additional wheels/tires.

Compared to the Jeep

So, say that the Ram 1500 Rebel TRX has 707 horsepower, 650 lb-ft of torque and weighs 6,000 pounds. The Jeep Grand Cherokee Trackhawk has the same horsepower, 5 less lb-ft of torque and weighs around 5,400 pounds in the real world. That number comes from a Trackhawk owner who put the SUV on a scale.

The rule of thumb in the drag racing world is that each 100 pounds added to a vehicle with add roughly a tenth of a second to the quarter mile time. If we assume a weigh difference between the Trackhawk and the Rebel TRX of 600 pounds, that would lead to roughly 6 tenths of a second in the quarter mile. Based on FCA’s official Trackhawk quarter mile time of 11.7, adding 6 tenths to that would put the Ram 1500 in the range of 12.3, but there is one more thing that we need to take into consideration.

The Trackhawk (and the Dodge Hellcat cars) have tires that are designed to yield lots of grip on a hard launch on pavement. The Rebel TRX tires will likely be aggressive off-road tires that are less-than-ideal for drag racing. Because of those tires, traction could be an issue with the Hellcat Ram, even with four-wheel-drive. As a result, the official quarter mile time (if the company issues one for an off-road truck) would likely be a touch slower than the 12.3 mentioned above.

Now, Jeep claims that a stock Trackhawk is good for a quarter mile time of 11.7, but when I checked out the Team Trackhawk Facebook page , I found that real world stock times are significantly quicker. Quite a few Trackhawk owners have gotten into the 11.30s and 11.40s, so beating the company time of 11.7 is very realistic. If you add 6 or 7 tenths to those times to figure out the Rebel TRX quarter mile times, the Hellcat Ram might be able to get into the 11s in stock form.


Also, if a Ram 1500 Rebel TRX owner swaps out the off-road tires for a set of lighter tires that are intended for hard digs on pavement, 11-second quarter mile times seem very possible. Of course, it won’t be 100% stock with different tires, but at the end of the day, a Ram 1500 that can run in the 11s with just a tire change is mighty impressive.

My guess is that if Ram issues an official quarter mile time, it will be in the mid-to-low 12-second range, but with different tires and good air, it should be an 11-second machine.
