Reportedly led by Auburn Hills, since the former Chrysler marques are the main users, STLA Large was unveiled in January 2024. The platform will be used for front, rear, and all wheel drive based vehicles in the D and E sizes (e.g. Charger, Quattorporte, Grand Cherokee, Pacifica), with flexibility in the wheelbase, length, width, height, ground clearance, and even engine mounting (transverse and longitudinal).
It can take a variety of suspension modules and powertrain cradles, so the feel and performance can be quite different—and Jeeps based on it can be trail rated for off-road driving. Engineers can even adjust dimensions such as the front spindle to the driver’s foot or the passenger compartment floor.
Eight STLA Large vehicles are to be launched from 2024-26; Dodge and Jeep come first (Charger, Wagoneer S) followed by Alfa Romeo, Chrysler, and Maserati. Erik Latranyi wrote that Toluca, Mexico, would join Windsor, Canada in building STLA Large vehicles; presumably Detroit Complex will also make them, while Brampton will make STLA Medium. Motors and electronics modules for STLA Large electric vehicles (EVs) will be made in Indiana.
The platform can support gasoline and hybrid-electric powerplants, with tranverse or longitudinal engine mounts, and front, rear, or all wheel drive. However, STLA Large is also a native battery-electric platform (possibly, though Stellantis has not mentioned this, with hydrogen options) with 400-volt and 800-volt architectures. Three-in-one electric drive modules (EDMs) include the motor, power inverter, and gear reduction; they can be set up to drive the front, rear, or all wheels. Silicon carbide semiconductors minimize power losses in the inverter. Over-the-air software updates can bring new features or resolve bugs without visits to the dealer in many cases. Other technologies compatible with the system are limited slip differentials and wheel-end disconnects to increase efficiency.
Stellantis explicitly stated that the platform can “carry extreme power that will outperform any of the existing Hellcat V-8s.” The first generation of components “holds the potential” to run 0-62 mph in “the 2-second range.” However, the first models will have battery packs with 85-118 kWh, with a targeted range of 800 km or 500 miles (sedans); fast charging can reach 4.5 kWh per minute with the higher-voltage battery pack.
There are actually four sub-platforms for STLA Large, all of which can handle AWD: LP1 (RWD), LP2 (FWD), LP3 (Italian RWD), and LP4 (SUV RWD). This puts Charger and Wagoneer S onto LP1, Cherokee, Recon, and others onto LP2, Stelvio, Giulia, and Levante onto LP3, and Grand Cherokee and maybe Durango onto LP4.
The LP2 (Cherokee and others) so far can handle battery-electric or hybrid, so far with the 1.6 turbo engine confirmed, but probably the 2.0 turbo later.
The platform can handle vehicles from 187.6 to 201.8 inches long (4.76-5.13 m), and 74.7 to 79.9 inches (1.9-2.0 m) wide. This is quite a wide range, but it gets better: the ground clearance can run from 5.5 to 11.3 inches (140-288 mm) and the wheelbase can run from 113.0 to 121.1 inches (2.9-3.1 m). Tires can run up to 32.6 inches (858 mm). This is the most popular size for recent Mopars in the U.S. and Canada.
Known cars under STLA Large so far include:

M6U - Maserati Levante
J6U - Jeep GC
D6U - Dodge Durango
The first letter is brand, second is platform (4=Medium, 5=Large/Short, 6=Large/Long), third is vehicle type (U=SUV, C=Coupe, S=Sedan, O=?, X=We ain’t tellin’!).
The next letters, not always included, is body style, followed by generation and manufacturing region. These usually aren’t shown.
