Stellantis' New STLA Large Platform Will Spawn 8 BEVs By 2026

Following the unveiling of the STLA Medium last July 2023, Stellantis has revealed the STLA Large platform — the second of the four global BEV platforms for the brand's next-gen cars. This unibody platform will underpin a wide array of full-size models in the D and E segments, aiming to launch eight models by 2026.

Dodge and Jeep are the first brands under the Stellantis umbrella to benefit from the STLA Large. The highly-anticipated electric Dodge Charger, which has already been spotted doing road tests, will be one of the first to be built on the platform, along with the Jeep Wagoneer S EV. Alfa Romeo, Chrysler, and Maserati are the other three brands destined to use the STLA Large platform.

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

The STLA Large is a flexible platform capable of underpinning various body styles, including cars and 4x4 SUV off-roaders. It has an overall length range between 187.6 and 201.8 inches, an overall width range between 74.7 and 79.9 inches, a wheelbase range between 113.0 and 121.1 inches, a ground clearance range between 5.5 and 11.3 inches, and a maximum tire diameter of 32.6 inches.

As such, models using the platform can host various suspension modules and interior layouts, as well as flexible drivetrain configurations that support front-wheel drive (FWD), rear-wheel drive (RWD), and all-wheel drive (AWD).

Regarding electric powertrain capabilities, STLA Large-based models can use either a 400-volt or an 800-volt EV architecture, paired with batteries ranging between 85 and 118 kWh. The platform has a 4.5 kWh per minute charging efficiency, a 0-62 mph acceleration within the 2-second range, and a range of up to 500 miles. The flexibility extends to enabling hybrid and ICE powertrains, suggesting the upcoming Charger will get a rumored ICE option.

Speaking of which, Stellantis claims the new platform has the potential to outperform any of the existing Hellcat V8s. Efficiency is also considered during the development phase, with components like cabin heating/cooling system, steering, braking assist, and propulsion optimized to minimize
