Stellantis took the V8 out of some of its most popular cars, like the Dodge Charger and Ram 1500 pickup trucks, which made a lot of people sad. The company’s new 3.0-liter twin-turbocharged Hurricane inline-six engine will almost always be used instead of the famous 5.7-liter Hemi engine. Most of the time, it’s a good substitute. It has more power and performance than the old V8. But there is one problem that might surprise you: gas mileage. The Environmental Protection Agency (EPA) just released the official fuel economy ratings for the 2025 Ram 1500 range. The range has three engine options: a Hurricane I6 with normal output, a Hurricane I6 with high output, and a Pentastar V6 mild hybrid that is the base model. The Hurricane I6 also gets worse gas mileage than older V8s, even though it has two fewer cylinders and a much smaller displacement. The Hurricane I6 high-output model will definitely be the thirstiest, getting 15 mpg in the city, 21 mpg on the highway, and 17 mpg overall. It has 540 horsepower and 521 lb-ft of torque. The old 5.7-liter V8 engine got 18 mpg in the city, 22 mpg on the interstate, and 19 mpg on the highway. The new engine gets less gas mileage in total. The high-output I6 costs more because it needs fuel with 91 gas. Since the V8 only had 395 horsepower and 410 lb-ft of torque, it’s important to note that this is a lot more powerful. However, even the normal output is relatively less fuel-efficient than the old V8. While the V8 gets the same combined number, this one gets 17 mpg in the city and 24 mpg on the highway, for a total of 19 mpg. The new standard-output I6 engine is better than the V8 even though it has 420 horsepower and 469 lb-ft of torque. It saves $2,000 in fuel over five years, according to the EPA. The old V8 will cost $3,500 less to run over five years than the high-output I6. The EPA knows that most Ram owners will stick with the standard-output I6, which is more than enough for the job the car needs to do and will save them money in the long run at the gas pump. Also, buyers won’t have to worry about the drop in gas mileage because the high-output engine is only available on the most expensive trim levels (Limited, Limited Longhorn, and Tungsten). There’s no doubt that the new I6 has more power than the old V8, which means it should do better in all areas, such as speed, pulling, and towing. It will cost more at the pump, though, because it will work better. This is another warning that lowering emissions does not mean getting better gas mileage or lower costs of owning a car.
