Importantly, claimed Stellantis, the platform “enables several segment-leading capabilities” that may play to the strengths of every model that may use it.
Alfa Romeo, for instance, will profit from its “high-performance vehicle dynamics”, whereas Jeep can exploit its “trail-rated off-road driving” credentials.
Outlining the platform’s flexibility, Marc Issner, who has overseen its growth, stated it will probably accommodate trip heights starting from 140mm to 287mm.
“If you want a curve-hugging, track-ready performance car, a smooth-riding luxury car or a rock-clearing off-roader, we’ve addressed these needs within the platform,” he stated.
He added that consumers of Alfa Romeo, Chrysler, Dodge, Jeep and Maserati vehicles “are passionate and very diverse” and added that Stellantis’s aim is to “avoid saying no to any of their product-specific requirements and requests”.
As a sign of its efficiency potential, Stellantis stated the quickest STLA Large vehicles will crack 0-62mph in round 2.0sec, with “extreme power that will outperform any of the existing Hellcat V8s”.
The just lately retired Dodge Charger Hellcat, for reference, packed 707bhp and 650lb ft of torque and so may crack the identical dash in round 3.7sec.
Stellantis additionally stated the STLA Large has been “optimised for weight and rigidity” and the parts used inside it are packaged as tightly as attainable to maximise inside area.
As an instance, all EVs primarily based on this platform will likely be powered by e-axles – compact models that comprise the motors, inverters and gearbox.
They will likely be fitted with a traditional 400V electrical structure as commonplace however can optionally be upgraded to an 800V system, which is able to permit charging at charges of as much as 270kW.
The largest battery out there will likely be a 118kWh unit giving a most vary of 500 miles in essentially the most aerodynamically environment friendly variants, however Stellantis stated it has engineered the platform to assist totally different battery chemistries and drivetrain applied sciences, suggesting this determine may rise sooner or later.
