Stellantis must have breathed a sigh of relief following the announcement of the EPA (Environmental Protection Agency), the organization that calculates official fuel consumption ratings in the United States, regarding the engine’s first application Hurricane. The latter revealed that the Jeep Grand Wagoneer with the Hurricane high-output 3.0-liter turbocharged 6-cylinder has lower fuel consumption than the 6.4-liter V8.
This new generation of engines in the Stellantis family marks the beginning of the end of the good old big V8 Hemi in all of the manufacturer’s ranges. We have known for several years now that these V8s are lacking in modernity and have changed only too little over the past 15 years. It is not the versions and the power that are lacking, but they consume and pollute too much.

Power to spare
The Hurricane arrives to save the day. Two versions are announced by the manufacturer. A basic version with ordinary performance will offer power around 400-420 horsepower and more than 450 lb-ft of torque. For this version, the official figures are not yet revealed. Next comes the High Output version, so the cavalry reaches 510 horsepower with 500 lb-ft of torque.
Frugal or not?
However, these inline 6-cylinders are very powerful and benefit from turbocharging. Therefore, even if they are highly more modern than the V8s, they could very well consume just as much gasoline. It is therefore for this reason that Stellantis must have been somewhat nervous about the unveiling of the first consumption figures.
13.8 litres/100 kilometers
Although these 6-cylinders were unveiled in the 2023 Jeep Grand Wagoneer L, there will be a few 2022 Jeep Grand Wagoneers that will be entitled to them. Being marketed, the EPA must provide fuel economy ratings and do their testing. We therefore learn that the Grand Wagoneer equipped with the High Output Hurricane will have an expected city consumption of 16.8 litres/100 kilometers, 11.7 litres/100 kilometers on the highway and a combined average of 13 .8 liters / 100 kilometers.
Better than the 6.4-liter V8
These numbers remain high, but are lower than those offered by the current 6.4-litre V8 (18.9 L/100 km city, 13 L/100 km highway and 15.7 L/100 km combined). We are still far from a fuel-efficient engine, but there is progress. Obviously, these figures are achieved under optimal conditions and without load.
And for the Wagoneer?
Barring a change, the regular-output 3.0-liter will arrive in the Wagoneer at the same time as the Wagoneer L, so for the 2023 model year. Considering the power is less swift, there should be another gain in terms of consumption. However, for the comparison, we will have to look at the side of the 5.7-liter Hemi V8. We will follow the file as the EPA provides data on the different versions of models equipped with the Hurricane.
ONECARSPOT’S NOTICE
Is it possible that the V8 Hemi era is really coming to an end at Stellantis? We are talking today about the Jeep Wagoneer, Grand Wagoneer and Grand Wagoneer L, but everyone knows that these two versions of the Hurricane engine will be called upon to replace the V8s at both Ram and Dodge in the years to come. To this, we must count on the possibility of a hybridization of the mechanics in one form or another. It is indeed the beginning of a new age at Stellantis after more than 70 years of Hemi.
