Stellantis launches BEV-native STLA Large Platform for D, E segments

Dodge and Jeep are to be the launch brands for Stellantis new BEV-native STLA Large Platform with Alfa Romeo, Chrysler and Maserati to follow by 2027.

Stellantis said its all-new platform will become the foundation for a wide range of new models in the D and E segments and will feature embedded energy, charging efficiency, high-performance vehicle dynamics and trail rated off-road driving capabilities.

STLA Large will be installed in several plants in Europe and North America and will be available in multi-energy variants including hybrid and internal combustion. The first vehicles will be driven in North America.

One of four global BEV platforms that will underpin the Stellantis Dare Forward 2030 strategic plan, it is the second platform to be revealed following the release of STLA Medium in July.

“Our goals for our STLA platforms are ambitious but this is what our customers need from us today,” said Stellantis CEO Carlos Tavares.

“Creating a family of vehicles from a well-engineered set of components that is flexible enough to cover multiple vehicle types and propulsions, overperforming any of our current products, will address each of our iconic brands’ customers. The flexibility and agility of this platform is its hallmark and will be a driving force for our success in the shift to electrification in North America.”

Stellantis said wheelbase, overall length, overall width and height, and ground clearance will be able to be adjusted. A variety of suspension modules and powertrain cradles can also be employed to suit vehicle specific performance objectives that include ride, handling and comfort.

Key dimensions, such as the front spindle to the driver foot, the front and rear overhang, or the passenger compartment floor, will also be able to adjust to fine-tune vehicle capabilities and performance.

STLA Large will be designed and engineered as a native BEV platform with the option of 400-volt and 800-volt electric architectures.

Three-in-one electric drive modules that incorporate the motor, power inverter and gear reduction can be configured in front-wheel-drive, rear-wheel-drive and all-wheel-drive layouts.

Embracing the importance of balancing driving range and cost, the platform initially includes battery pack options with energy ratings between 85 and 118 kilowatt hours (kWh). STLA Large targets an overall range of 800 km/500 miles for saloons and is engineered to accept future energy storage technologies when they reach production readiness.

The initial generation of propulsion components will deliver acceleration of 0-100 km/h (62 mph) in the 2-second range. Fast charging will add up to 4.5 kWh per minute to the 800-volt battery pack.
