The order books are now full for the 710 horsepower 2021 Dodge Durango SRT Hellcat that went on sale last November at a starting price of $83,160.

Dodge has confirmed that its planned run of 2,000 vehicles is spoken for, and it won't be building anymore because it won't be able to pass the more stringent emissions rules going into effect in 2022.

The three-row Durango is powered by a version of the 6.2-liter supercharged V8 also offered in the Challenger and Charger, along with the Jeep Grand Cherokee Trackhawk and Ram 1500 TRX.
