Dodge is working on an all-wheel-drive Challenger.

The car was first hinted at by the Challenger GT AWD concept unveiled at the 2015 SEMA show and now confirmed by an early listing on the EPA’s website that lists fuel economy ratings.

A 2017 Dodge Challenger GT equipped with a 3.6-liter V-6 and 8-speed automatic is listed as having a fuel economy of 18 mpg city, 27 highway and 21 combined. Under the Specs tab on the EPA website, the vehicle is also listed as having all-wheel drive. This compares with the regular 2017 Dodge Challenger equipped with the same engine and transmission which is rated at 19 mpg city, 30 highway and 23 combined.

The numbers are not surprising considering all-wheel-drive systems normally increase fuel consumption.

Dodge is expected to add the Challenger GT to its lineup this fall. It will be available exclusively with a V-6 engine, rated at 305 horsepower and 268 pound-feet of torque. The Challenger’s V-8s have been ruled out due to tight packaging and torque constraints of the all-wheel-drive system, which is borrowed from the Charger.

Though it’s yet to be confirmed, it’s thought that the Challenger GT will feature a distinct wide-body design. This wide-body design will also be used for a new range-topping model positioned above the current Challenger SRT Hellcat. The new model, thought to be called a Challenger ADR, has been spied as a prototype.
