Stellantis unveils STLA Large Platform with 497 miles range

Stellantis unveiled the STLA Large Platform today, which will underpin eight new vehicles from its vast array of brands between this year and 2026. Dodge and Jeep will lead with launches in North America, followed later by Alfa Romeo, Chrysler, and Maserati.

The STLA Large Platform is going to be available in both 400-volt and 800-volt architectures, and it's built with flexibility at the core. Vehicles based on it can be between 187.6 inches and 201.8 inches long, between 74.7 inches and 79.9 inches wide, and will have a wheelbase between 113 inches and 121.1 inches.

Similar flexibility is enabled for ground clearance, which can go from 5.5 inches all the way up to 11.3 inches. The maximum tire diameter for cars using STLA Large is a whopping 32".

STLA Large initially includes battery pack options between 85 kWh and 118 kWh. The 800-volt battery pack will recharge up to 4.5 kWh per minute. The maximum target range for vehicles using the platform initially is 497 miles.

The first generation of propulsion components will potentially deliver 0 to 62 mph acceleration in the 2-second range. Front wheel drive, rear wheel drive, and all wheel drive will be supported, and Stellantis says the new platform has "the potential to carry extreme power that will outperform any of the existing Hellcat V-8s".

The new platform will be one of four allowing Stellantis to reach its electrification goals over the next few years, along with STLA Small, STLA Medium, and STLA Frame. All of these are designed and engineered for extended lifecycles via interchangeability of battery cell chemistry, electric drive modules, power inverters, and software control.

STLA Large supports Stellantis' next-gen electrical and software-defined vehicle technologies: STLA Brain, STLA SmartCockpit, and STLA AutoDrive. Stellantis is investing $54 over the next decade in electrification in order to reach its target of selling only pure all-electric passenger car EVs in Europe by 2030, as well as 50% passenger car and light-duty truck EVs in the US by the same year. The company wants to have 48 EVs offered in various markets by the end of this year.
