STLA Medium: Stellantis revealed its latest EV platform

  • The maximum range is 700 km (434 miles) with the Performance Pack.

  • The STLA Medium platform will be used in many applications.

  • The regular model offers up to 500 km (310 miles) of range.


The Stellantis group, which englobes several American, French and Italian brands, has unveiled its new STLA Medium platform, designed entirely for electric propulsion. This is the first architecture planned by automotive giant Stellantis, which plans to add three more in the coming months and years: Small, Large and Frame.

Stellantis aims to sell only battery-electric vehicles (BEV) in Europe by 2030, while in North America the goal is to sell a 50% proportion of electric vehicles by 2030, while continuing to sell ICE-powered vehicles. Carbon neutrality would be achieved by 2038.

This new architecture, conceived for a multitude of vehicles, is capable of accommodating a wheelbase of between 2,700 and 2,900 millimeters, a vehicle length of between 4.3 and 4.9 meters, and a ground clearance of up to 220 millimeters.

But what really interests EV enthusiasts is the capacity of the battery pack. The STLA Medium platform is said to be capable of driving up to 700 km between charges. Unsurprisingly, this distance was calculated using the WLTP cycle, which is more optimistic than the one used in North America. This 700 km range is made possible by the addition of the Performance Package. The regular package gives the platform a possible range of 500 km, again according to the WLTP cycle.

The useful battery capacity is 98 kWh, while the platform uses 400-volt technology, with a potential average consumption estimated at 14 kWh/100 km. Stellantis also estimates that recharging from 20% to 80% of the battery’s energy would require 27 minutes, or, according to the brand, an average of 2.4 kWh per minute.

This STLA Medium platform will be used for all purposes within the Stellantis empire, whether as a front-wheel-drive or all-wheel-drive layout, while power output is expected to range from 160 to 285 kW (214 to 382 hp).

Stellantis also indicated in its press release that it had considered the evolution of battery technology. The platform would therefore be designed to accommodate a solid-state battery pack, or even a nickel- and cobalt-free battery.
