It is still better than the Ram TRX but only barely.
Let’s face facts. The Jeep Wrangler Rubicon392 was not expected to be a hero in fuel economy. We are not sure anyone who is considering the V8-powered Wrangler would be interested in such things. The official fuel economy ratings of the EPA for this vehicle are only 13 mpg in the city and 17 mpg on the highway. This gives it a combined rating that is just 14 mpg. Ouch, Jeep.
We couldn’t resist making comparisons with other Wrangler models. The 3.0-liter turbocharged EcoDiesel gets 23 combined mpg and 26 on the highway if you swap gasoline for diesel. Although the Hemi’s horsepower is lower than the diesel, the diesel’s torque is almost equal at 442 pound-feet to 470. The turbocharged 2.0-liter Wrangler’s combined fuel economy is 22 combined mpg. This is almost the same as the V6’s 21 combined. These figures are for four-door models that have automatic transmissions. The official ratings for the plug in hybrid 4xe have not yet been released.
The Dodge Challenger can reach 60 mph in just 4.5 seconds. None of the Wranglers can do that. The same 6.4-liter engine makes 485 horsepower, but it gets much more mileage at 18 combined mpg and 24 on the highway. The Wrangler’s aerodynamics and gearing are definitely disadvantageous, but the Ford Explorer ST is also a better choice. Although it is a full second slower than 60 mph, the combined fuel consumption of the Explorer ST is 20 mpg.
You will need to look for vehicles that have similar fuel economy ratings to the Wrangler Rubicon 392 and big. Although the Hellcat-powered Dodge Durango SRT Hellcat has a slightly lower fuel economy of 13 mpg, it still packs more than 700 horsepower from its supercharged 6.2-liter V8. The Ram TX and its Hellcat get 12 combined mpg. The Lamborghini Huracan is slightly more efficient than the McLaren. To do worse, you need to take the Lamborghini Aventador or Bugatti Chiron up to the pump. However, they won’t take your rock crawling to Moab.
Yes, there have been some crazy comparisons made here. Perhaps you are already making a comment about how it doesn’t matter. You know what? You are absolutely correct. You are absolutely correct. While the Mercedes AMG G63 can be used off-road, it is quite different in terms of price, luxury, power, and performance. The Bronco-Warthog will compete directly and will likely perform better at the pump. The Wrangler Rubicon392 is rumored at nearly $80,000 so buyers won’t be too concerned about the poor fuel economy.
