The flexibility includes the unibody platform’s propulsion systems. STLA Large is 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 (EDMs) that combine the motor, power inverter and gear reduction can be configured in front-wheel-drive, rear-wheel-drive and all-wheel-drive layouts. The power inverter uses silicon carbide semiconductor technology to minimize power losses. Propulsion system performance can be upgraded during the vehicle’s lifespan via over-the-air software updates.

Based on specific vehicle objectives, STLA Large accepts drivetrain improvements such as limited slip differentials or wheel end disconnects that can increase performance or reduce mechanical drag to increase efficiency and range. Overall, the STLA Large platform has the potential to carry extreme power that will outperform any of the existing Hellcat V8s.

The STLA 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 sedans and is engineered to accept future energy storage technologies when they reach production readiness.

The initial generation of propulsion components holds the potential to 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.

STLA Large also supports hybrid and internal combustion propulsion systems without compromising key vehicle capabilities, it’s said. The flexibility provides a bridge for customers around the world during the transition to electric propulsion and the development of a robust and widely available charging network. Design flexibility includes transverse and longitudinal engine mounting configurations, supporting FWD/RWD/AWD drivetrains.

Key STLA Large metrics:

• Overall length range: 187.6-201.8 inches (4,764-5,126 mm)
• Overall width range: 74.7-79.9 inches (1,897-2,030 mm)
• Wheelbase range: 113.0-121.1 inches (2,870-3,075 mm)
• Ground clearance range: 5.5-11.3 inches (140-288 mm)
• Maximum tire diameter: 32.6 inches (858 mm)

The four Stellantis global BEV platforms – Small, Medium, Large and Frame – are designed and engineered for extended lifecycles via the interchangeability of battery cell chemistry, EDMs, power inverters and software control. The STLA Large platform supports Stellantis’ next-generation electrical and software-defined vehicle technologies – STLA Brain, STLA SmartCockpit and STLA AutoDrive.

Stellantis is investing more than €50 billion over the next decade in electrification to deliver on the targets of reaching a 100% passenger car BEV sales mix in Europe and 50% passenger car and light-duty truck BEV sales mix in the United States by 2030. To achieve these sales targets, Stellantis is securing approximately 400 GWh of battery capacity, including support from six battery manufacturing plants in North America and Europe. Stellantis plans to have 48 BEVs on the market by 2024 and is on track to become a carbon net zero corporation by 2038, all scopes included, with single-digit percentage compensation of remaining emissions.
