Stellantis unveils first of four platforms for future BEV models

Stellantis has unveiled STLA Medium, a global platform with state-of-the-art features for battery electric vehicle (BEVs) with energy efficiency, embedded power, charging power and a claimed range of 500 – 700 kms.

With 15 motor vehicle brands in its group and 26 vehicle nameplates currently on different platforms, STLA Medium will streamline manufacturing with just four platforms to be used for up to 2 million vehicles a year.

First of 4 global platforms
The STLA Medium platform is designed for use with a variety of vehicles – largely in the C and D segments – and drivetrains.

It is the first of four global BEV platforms that Stellantis will use as it moves towards a target of 100% passenger car BEV sales mix in Europe and a 50% passenger car and light-duty truck BEV sales mix in the USA by 2030.

STLA Medium, which uses a 400V electric architecture, will have best-in-class energy efficiency and charging time and connectivity to a charging and services ecosystem.

Owners will be able to recharge their battery pack from 20% to 80% charge in 27 minutes. Depending on the application, consumption can be less than 14 kWh per 100 km, which is said to be best in class in energy efficiency.

Caters for different bodystyles
The flexibility of STLA Medium gives Stellantis designers the freedom to create vehicles with passenger car, crossover and SUV bodystyles and with FWD or AWD.

There will be a family of 3 scalable electric drive modules with electric motors generating 160 to 285 kW and receiving energy from modular, high-energy density single-layer battery packs.

Engineering and manufacturing experts are focused on making installation of the battery packs at the assembly plant as efficient as possible, maximizing space inside the vehicle and improving ride and handling with a low centre of gravity.

Platform components such as the cabin heating/cooling system, steering, braking assist and propulsion will be designed to minimize energy consumption.

Future-proofed platforms
The platforms are designed with provisions for future battery chemistries, including nickel-free, cobalt-free and solid-state batteries. This will enable Stellantis brands to tailor vehicle capabilities for the ideal balance of cost and performance.

The capabilities and performance of STLA-based vehicles will adapt and improve over the years with the implementation of the STLA Brain architecture, STLA SmartCockpit and STLA AutoDrive platforms,  enabling over-the-air updates to software and enhanced hardware.

“What we see today is the product of just over two years of no-compromise innovation to deliver clean, safe and affordable mobility, supported by our €30 billion investment in electrification and software through 2025,” said Carlos Tavares, CEO of Stellantis. “The STLA Medium platform demonstrates the power of the global Stellantis technical community, delivering products that are hyper-focused on our customers and rewriting long-held assumptions of transportation as we drive for carbon net zero by 2038.”
