Dodge Durango SRT Hellcat Drivetrain, Performance Figures, and Fuel Economy

Power is sent to all the wheels as standard via an eight-speed TorqueFlite automatic gearbox. The same engine is plonked in the Jeep Grand Cherokee Trackhawk, too, but there it makes three horses less.
Complementing the engine is a 2.38-liter supercharger with twin-screw rotors to minimize air leakage and increase performance. This supercharger has a maximum speed of 14,600 rpm and has a drive ratio of 2.36:1. It can regulate a boost pressure up to 11.6 psi, courtesy of an integrated electronic bypass valve.
The engine comes with stuff like aluminum-alloy cylinder heads, forged steel crankshaft, specially-tuned crankshaft damper, and so on. The folks at Dodge even created a special cooling circuit that includes a water pump, coolant reservoir, and a heat exchanger. It helps keep the intake air temperatures below 140 degrees Fahrenheit, thus optimizing performance.

Dodge Durango SRT Hellcat Interior Design and Technology
Step inside and you’ll be welcomed to a rather sporty cabin. The automaker has opted for a Challenger-inspired cockpit here. The driver-centric setup features an SRT-badged flat-bottom steering wheel that’s lied straight from the Challenger. The instrument cluster also features red gauges. It free flows into the infotainment system and gives the vibes of both being in a conjoined unit. It looks very different from the previous model year Durango.
The Durango SRT Hellcat comes with black leather seats with suede inserts as standard. The only other upholstery on offer is a $1,595 option that wraps the seats in Laguna leather. Our test model came with these seats. On the center console, there’s a 10.1-inch touchscreen that runs on FCA’s UConnect 5 infotainment system. It supports Apple CarPlay, Android Auto, as well as Amazon Alexa. Stuff like navigation, HD Radio, Bluetooth, and a few Sirius XM subscriptions are offered, too. People who prefer good beats and acoustics to the Hellcat’s grunt can opt for the 19-speak Harman Kardon audio system.
Courtesy of the neatly laid out dash, Dodge was able to provide a multitude of cup holders and cubby holes. In fact, there’s a slot to place the key fob right behind the gear shifter and a wireless charging pad in front of it. There are forged carbon fiber trims all around that give the cabin a sporty and premium vibe.
Another interesting option here is the Lightweight Performance Package that is offered at no extra cost. Basically, the third row is taken out here and your Durango is transformed into a five-seater with a 60:40 split rear bench. If the seating configuration was your only reason for picking the Grand Cherokee Trackhawk over the cheaper Durango SRT Hellcat, well, Dodge has solved it for you.

This makes it around $7,000 cheaper than the Jeep Grand Cherokee Trackhawk. The GLS63 is in a different league altogether, starting at around $130,000. The SRT Hellcat is also the priciest model in Durango’s lineup, making it over $16,000 more expensive than the next-placed SRT.
The Durango SRT Hellcat’s chief rival is its cousin, the Jeep Grand Cherokee Trackhawk. There is nothing modest about this SUV. It’s big, brawny, luxurious, loud, and insanely fast. It rides on 20-inch wheels wrapped in 295/45 section tires. The SUV is powered by the same 6.2-liter, supercharged V-8 HEMI engine that dishes out 707 horses and 645 pound-feet of torque. Three horses less don’t make much of a difference, but on paper, the Durango is still more powerful.
The biggest difference is that the Trackhawk comes with a two-row setup, unlike the Durango’s three-row configuration. You can opt for a third-row delete in the latter if you’d like to. It comes with a smaller 8.4-inch touchscreen system that runs on the UConnect 4 system. Both being FCA products, there aren’t a whole lot of other differences that set them apart. You would expect them to be priced on par or have a price difference of probably a couple of thousand bucks. But, the Jeep Grand Cherokee Trackhawk is significantly more expensive, starting at $89,615. This makes it over $7,000 more expensive than the Durango SRT Hellcat.
