The Wrangler Backcountry arrives at Jeep dealerships in late November.
The Grand Cherokee SRT Night goes on sale in the first quarter of 2016.
Pricing has not been announced.
Jeep said the Wrangler Backcountry is aimed at "snow lovers."
It is spun off the Wrangler Sahara model and features Backcountry decals, a unique off-road front and rear powder-coated bumper, 17-inch Rubicon wheels painted in Mid-Gloss Black and a black fuel-filler door.
A black hardtop is standard and an optional body-color hardtop is available.
The cabin features Piano Black trim, black McKinley leather seat bolsters with black sport mesh inserts, a nine-speaker premium Alpine sound system and all-weather slush mats.
A black appearance package underpins the Grand Cherokee SRT Night.
Details include a unique black roof and lightweight performance wheels.
Exterior color choices include Velvet Red, Billet Silver and Granite Crystal.
Options include a dual-pane sunroof, trailer tow package and dual-screen rear entertainment system.
Edmunds says: Jeep buyers can't seem to get enough of these special-edition models, and the popular brand keeps the momentum going for the L.A. auto show.
