2021 Dodge Durango SRT Hellcat in Highland

Designed and engineered to push the boundaries of what an SUV can be, the 2021 Dodge Durango SRT Hellcat is powered by the proven supercharged 6.2-liter HEMI Hellcat V-8 engine, which delivers a best-in-class 710 horsepower and 645 lb.-ft. of torque, mated to a standard TorqueFlite 8HP95 eight-speed automatic transmission.

The performance improvements begin with the new front fascia design, a new chin splitter, updated engine oil cooler duct, air guide and snorkel for cold air induction. A new, unique rear spoiler creates an improved aerodynamic balance with the new front-end design, resulting in a massive increase in rear downforce of more than 400 percent (140 lbs. @ 180 mph).

 

SRT engineers upgraded the Durango SRT Hellcat to improve handling, including several race-inspired technologies and Brembo brakes, resulting in performance numbers never before seen on a Durango.

 

Compared with the previous top performance Durango, the 2020 Durango SRT 392, the new 2021 Durango SRT Hellcat has an upgraded suspension that delivers:

  • More comfort in Auto mode and better handling in Track mode:
    • Thanks to a tuned internal rebound spring coupled with a matched upper top mount, the dynamic tuning range is increased
    • Rear damper top mounts are 18 percent stiffer
  • More responsiveness with 20 percent increase in total rebound control
  • More grip with reduced understeer by 2.5 percent, allowing the driver to go into a corner faster and exit quicker
  • More stability turning into corners with an improved roll gradient of 5 percent


The 2021 Durango SRT 392 adopts the rebound spring shocks and the upper rear top mounts from the SRT Hellcat suspension, which helps to deliver faster lap times and better handling compared to the outgoing model.

 

The Durango SRT Hellcat comes standard with electric power steering (EPS) with selectable steering tuning to better manage increased grip, both improving handling performance and delivering better steering feel and ease of turning efforts at parking lot speeds.

  • With EPS and standard SRT drive modes accessed via the new 10.1-inch touchscreen, drivers can tailor their driving experience by controlling transmission shift speeds, steering, paddle shifters, traction, all-wheel drive (AWD) and suspension settings
  • SRT Drive modes offer selectable settings for Street (Auto), Sport and Track, while the Custom setting allows the driver to select individual preferences

Race-inspired technologies that come standard for both 2021 Durango SRT models also bolster performance:

  • Launch Control – easily accessed from a toggle switch in the cockpit, manages tire slip while launching the vehicle to allow the driver to achieve consistent straight-line acceleration
  • Launch Assist – uses wheel speed sensors to watch for driveline-damaging wheel hop at launch and, in milliseconds, modifies the engine torque to regain full grip 

The 2021 Dodge Durango SRT Hellcat delivers excellent braking performance, requiring 116 feet to come to a full stop from 60 mph. The credit belongs to the massive standard Brembo high-performance six-piston, two-piece (front) and four-piston (rear) calipers, and vented rotors at all four corners measuring 15.75 inches (front) and 13.8 inches (rear).

 

Durango-specific tuning, weight distribution, wheelbase and reduced understeer equals more grip and improved cornering. SRT engineers took the most powerful SUV ever to the track to see what it can do.

 

The result: The 2021 Durango SRT Hellcat runs 0-60 mph in 3.5 seconds, covers the quarter-mile in 11.5 seconds and has a top speed of 180 mph. It also delivers a road course lap time 1.5 seconds faster than the 2020 Durango SRT 392 on a 2.1-mile road course, equal to 9 car lengths after one lap.
