The new 3.0-liter inline-six twin-turbo "Hurricane" engines coming from Stellantis will slot into engine bays currently occupied by some of the best motors ever at Dodge, Ram and Jeep.
The Pentastar V-6, entering its 12th year of production in 2023, has been a workhorse, delivering a competitive blend of power and fuel economy and an admirable record for durability. But time has caught up with the Pentastar.
The most powerful versions of the Pentastar V-6 can be found in the Ram 1500 pickup. At 305 hp and 269 pound-feet of torque, the engine is adequate but not class-leading. And because Stellantis is planning on internal combustion-engine vehicles accounting for half of sales after 2030, it still must reduce emissions and improve fuel economy.
It needs a better, more modern six-cylinder engine.
The Hemi V-8 engine in Dodge, Ram, Jeep and Chrysler vehicles, now in its 20th year, is legendary and a fitting close to the modern horsepower wars. Some versions of the Hemi produce a stunning 807 hp. But time has also caught up with the Hemi.
In big, heavy vehicles such as the Jeep Grand Wagoneer, fuel economy can be as low as 13 mpg city, 21 highway and 16 combined — atrocious by today's standards.
There are cleaner, faster and smarter ways now to blast away from traffic lights than with a huge V-8 engine. A Lucid Air electric vehicle, for instance, can reach 60 mph in just 2.4 seconds.
