Stellantis Spells Out its BEV Platform Ambitions

Automaker conglomerate, Stellantis, has announced its plan to create four BEV dedicated vehicle platforms to cover most of the most popular future segments.

It says these will form the backbone of the electrified vehicles from Stellantis’s 14 individual brands. The platforms are designed with a high level of flexibility, both in length and width, and component sharing, in a bid to deliver economies of scale with each platform supporting production of up to two million units per year.

The four platforms are:

  • STLA Small – urban focused with a claimed range up to 300 miles;
  • STLA Medium – family friendly vehicles with ranges up to 440 miles;
  • STLA Large – executive and muscle cars with range up to 500 miles;
  • STLA Frame – light commercial vehicles with ranges up to 500 miles.

Propulsion includes a family of three electric drive modules (EDM) that combine the motor, gearbox and inverter. These EDMs are compact, flexible and can be easily scaled. The EDMs can be configured for front-drive, rear-drive, all-wheel drive and 4xe. The combination of the platforms, EDMs and high energy-density battery packs is hoped to deliver vehicles with best-in-class performance in efficiency, range and recharging.

A program of hardware upgrades and over-the-air software updates will help to extend the life of the platforms well into the next decade, the automaker claims. It will also develop software and controls in-house in the hope to brand differentiation might be maintained in spite of the modular approach.

Use of two battery chemistries is planned by 2024 to support various customer needs: a high energy-density option and a nickel cobalt-free alternative. By 2026, the first competitive solid-state battery technology is targeted to be introduced.

Stellantis says it is currently involved in or is completing several technology joint ventures, ranging from e-powertrain and e-transmission operations to battery cell chemistry and production and digital cockpit and personalized connected services. CEO Carlos Tavares, said: “Our electrification journey is quite possibly the most important brick to lay as we start to reveal the future of Stellantis just six months after its birth, and now the entire company is in full execution mode to exceed every customer’s expectations and accelerate our role in redefining the way the world moves. We have the scale, the skills, the spirit and the sustainability to achieve double-digit Adjusted Operating Income margins, lead the industry with benchmark efficiencies and deliver electrified vehicles that ignite passion.”
