The Jeep Grand Cherokee is an undisputed hit in the US market; 2019 represented the model's best year for US sales since the turn of the century, with around 243k units sold. Even still, the current-generation WK2 model has grown quite long in the tooth, having been on the market without a major overhaul since 2011. A replacement is long overdue.

Now, we might finally know when the all-new, next-generation Jeep Grand Cherokee is set to debut, thanks to an email sent out to select customers this week that teases a "big reveal" set to occur on Thursday, January 7.

"The most awarded SUV ever is adding something new to the adventure-a third row," the email reads, inviting individuals to sign up "to be among the first to receive updates and save the date for the big reveal." It then provides a time and date for the big event: Thursday, January 7, at 12pm Eastern Time.

We've known for some time that an all-new Grand Cherokee is on the way, reportedly with bold new looks that borrow from the forthcoming Jeep Grand Wagoneer, an optional third-row, and a chassis based on the Alfa Romeo Stelvio's lightweight Giorgio platform. What we didn't know is that the new fifth-generation model might be arriving so soon.

Granted, the new Grand Cherokee isn't expected to start production until next summer or fall, and what we don't know about the new mid-size crossover far outweighs what we do know. The matter of what will power the next-generation model line is still a mystery, for instance. A turbocharged four-cylinder is expected to serve as the base engine, with Chrysler's 3.6-liter Pentastar V6 serving as an optional upgrade, but whether or not a V8 or two might again join the fray is unknown.

Thankfully, we might not have to wait long to find out.
