The STLA Large platform is Stellantis' global architecture for premium and high-performance electric models. A native BEV, with batteries up to 118 kWh and a claimed range of up to 800 km (WLTP) , it offers ultra-fast 800V charging and multi-energy support. Stellantis promises performance from 0–100 km/h in 2 seconds and more power than any V8 Hellcat produced to date.

STLA LARGE PLATFORM: THE FUTURE OF STELLANTIS PREMIUM CARS

The STLA Large is the new architecture developed by Stellantis to accommodate the premium and electric models of its brands (Alfa Romeo, Maserati, Chrysler, Dodge, Jeep). It is a native electric vehicle (BEV) platform, designed to guarantee a range of up to 800 km (WLTP ), extreme performance, and advanced electronics with over-the-air updates.

🔋 Batteries and autonomy

• Available capacities : from 85 to 118 kWh.
• Declared range : up to 800 km WLTP.
• Thermal management : advanced cooling and pre-conditioning systems.

⚡ 400V/800V charging

• Compatible with both 400V and 800V .
• Ultrafast charging : up to 4.5 kWh/minute.
• Claimed times : 10–80% in less than 20 minutes with 350 kW HPC columns.

This means that in less than 10 minutes you can recover over 200 km of range.

🏁 Declared performance

• Acceleration : 0–100 km/h in around 2 seconds on the more powerful versions.
• Power : More than any Hellcat V8 ever produced (over 700 equivalent horsepower).
• Available configurations : FWD, RWD, AWD thanks to the integrated EDM modules.

📏 Dimensions and modularity

Parameter	Values
Vehicle length	4.76 – 5.12 m
Length	1.89 – 2.03 m
Step	2.87 – 3.07 m
Ground clearance	140 – 288 mm
Tire diameter	up to 858 mm

💻 STLA Brain and SmartCockpit software

The electronic part is one of the pillars of the platform:

• STLA Brain : Centralized management with continuous OTA updates.
• STLA SmartCockpit : Advanced infotainment with predictive AI, developed with Foxconn.
• STLA AutoDrive : Level 3 autonomous driving capability.

⚙️ Multi-Energy: EV, hybrid, and gasoline

Although it is fully electric, the STLA Large platform remains flexible and can also accommodate plug-in hybrid and gasoline engines . This will allow Stellantis to sell models in markets where the electric transition is not yet mature.

🚗 Stellantis models on STLA Large

• Dodge Charger EV (2024)
• Premium Electric Jeep (2025)
• Alfa Romeo Stelvio (2026)
• Alfa Romeo Giulia (2027)
• New Chrysler and Maserati models are coming soon.

🌍 Stellantis Dare Forward 2030 Strategy

The STLA Large platform is part of the Dare Forward 2030 plan, which includes over €50 billion of investments in electrification and the launch of more than 75 BEV models by 2030. The goal is for electric vehicles to represent 100% of sales in Europe and 50% in the United States .

🛠️ Note from the workshop: maintenance and updates

Our partner mechanics have a key concept: less mechanical maintenance, more attention to software and batteries. With STLA Large, this becomes essential:

• Check battery cooling systems periodically.
• Keep your software updated via OTA.
• Check for official update campaigns when purchasing a used vehicle.

Workshop note: “The STLA Large base allows for constant software updates, a bit like what happens on Teslas: less traditional maintenance, more attention to firmware and digital diagnostics.”
