At 6,439 pounds (2,920 kilograms), the TRX is one of the heaviest vehicles money can buy. It also happens to have a thirsty 6.2-liter supercharged V8 engine, so fuel efficiency wasn’t a priority when Ram developed the off-road machine. Indeed, the EPA rates this 2022MY at just 10 miles per gallon in the city and 14 on the highway, producing a combined 12 mpg. That’s just as bad as its main competitor, the Ford F-150 Raptor R.
The gas-guzzling super truck underwent a range test to see how far it would go before running out of gas. Since the trip computer indicated a range of 36 miles (58 kilometers), the owner decided to speed up the process and push hard to consume fuel. With the launch control system turned on, the Ram TRX manages to sprint from 0 to 60 mph in a stunning three and a half seconds. The remaining range eventually dropped from 10 miles to “low”.
At that time, the truck averaged just 9.9 mpg, which is 23.7 liters / 100 kilometers. The test started after resetting the trip computer and putting the truck in auto mode while trying to drive it conservatively on the highway. We should point out that the TRX Ram comes with a 33 gallon fuel tank. As expected, the trip computer was developed to be foolproof in the sense that you should be able to cover a considerable distance before effectively running out of gas.
It covered a decent 26.8 miles (43.1 kilometers) in 25 minutes before drivers had to pull over. During this experiment, he managed to increase efficiency to 12.9 mpg (18.2 liters / 100 km), which is still not great, but still an increase of 3 miles per gallon. Of course, the truck failed to start afterwards, but was back on the road after the owner put about three gallons of fuel he had in reserve in the TRX bed.
In a similar test conducted about five years ago, the YouTubers did 49.2 miles (79 kilometers) in the Ford F-150 and 21.6 miles (35 kilometers) in the Fusion.
