What do a big Jeep, an opulent Maserati SUV, a blisteringly fast Alfa Romeo and a Dodge muscle automotive all have in widespread? Quickly sufficient, when these issues go electrical, they’ll have the identical {hardware} beneath.
Final week, Stellantis unveiled its new STLA Massive platform, will flexibly underpin vehicles, crossovers, and SUV car sorts of many styles and sizes. Engineers and executives say the STLA Massive platform will probably be BEV-native, which signifies that by default it is designed for battery-electric automobiles (BEVs), though it is a multi-energy platform that may additionally assist hybrid, plug-in hybrid, and inside combustion engine motors too.

Stellantis develops 4 STLA platforms
Stellantis plans to have 4 world BEV platforms—Small, Medium, Massive and Body. They are going to be used globally to attain the goal of a 100% passenger automotive BEV gross sales combine in Europe and a 50% passenger automotive and light-duty truck BEV gross sales combine in the USA by 2030.
In keeping with the corporate, the STLA Massive platform will are available in single-motor and dual-motor variations, and deal with quite a lot of powertrain varieties, together with all-electric FWD, RWD, and AWD setups. It can assist 85 kWh battery packs on base variations and bigger 118 kWh packs in high-spec fashions, so this huge platform will include bigger batteries too. Nonetheless, the platform has been designed with the interchangeability of battery cell chemistry in thoughts, and we will count on greater values sooner or later as effectively.
In keeping with Stellantis, the 118-kWh battery is predicted to be large enough to attain as much as 500 miles of vary (on an unnamed check cycle) within the case of sedans. That interprets to 236 Wh per mile.
One other factor is that the battery system will be 400-volt or 800-volt, relying on the producer’s selection for specific fashions.

Stellantis additionally says that the quick charging of STLA Massive-based BEVs will add as much as 4.5 kWh per minute within the case of the 800-volt battery pack. Utilizing this quantity we will make some calculations:
Fee: 4.5 kWh per minute (or some 270 kW) Quick charging (118 kWh): 20-80% SOC (70.8 kWh)- 16 minutes assuming a theoretical best-case situation of flat peak charging rate- half-hour if the typical charging energy exceeds 141 kW (half of the height)

Stellantis famous that the STLA Massive platform is prepared for high-performance automobiles. In prime configurations, all-electric vehicles will speed up from 0-62 mph (100 km/h) within the “two-second vary.”
EVs will probably be outfitted with three-in-one electrical drive modules that incorporate the motor, energy inverter (silicon carbide semiconductors), and kit discount.
One of the vital fascinating issues is that the platform could be a base for high-performance vehicles, in addition to for giant SUVs for off-road driving: “Primarily based on particular car goals, STLA Massive accepts drivetrain enhancements comparable to restricted slip differentials or wheel finish disconnects that may enhance efficiency or cut back mechanical drag to enhance effectivity and vary. General, the STLA Massive platform has the potential to hold excessive energy that may outperform any of the present Hellcat V-8s,” firm officers mentioned.
Flexibility seems to be the primary precedence for Stellantis, which says that the brand new platform offers a bridge throughout the transition to electrical propulsion, in addition to cost-efficient manufacturing processes that may be duplicated in a number of meeting vegetation.
The STLA Massive will probably be produced at a number of vegetation in Europe and North America and bought globally with eight car launches throughout 5 manufacturers deliberate from 2024-2026. Will probably be used first within the North American market on Dodge and Jeep manufacturers, adopted by different manufacturers together with Alfa Romeo, Chrysler, and Maserati.

“Our objectives for our STLA platforms are formidable however that is what our clients want from us right now,” Stellantis CEO Carlos Tavares mentioned in an announcement. “Making a household of automobiles from a well-engineered set of elements that’s versatile sufficient to cowl a number of car varieties and propulsions, overperforming any of our present merchandise, will deal with every of our iconic manufacturers’ clients. The flexibleness and agility of this platform is its hallmark and will probably be a driving pressure for our success within the shift to electrification in North America.”
STLA Massive’s flexibility contains adjustable dimensions (wheelbase, general size, general width and top, and floor clearance), and quite a lot of suspension modules and powertrain cradles to go well with vehicle-specific efficiency goals that embody experience, dealing with, and luxury.
All key consolation and efficiency elements, such because the cabin heating/cooling system, steering, braking help, and propulsion are designed to attenuate vitality consumption to boost driving vary, Stellantis explains. Over-the-air software program updates for the propulsion system had been talked about as effectively.

In complete, there will probably be 4 Stellantis world BEV platforms—Small, Medium, Massive and Body, outlined within the Stellantis EV Day 2021 presentation in July 2021. The STLA Medium was unveiled in July 2023.
Stellantis plans to take a position over $54 billion (about €50 billion) to ship on the targets of reaching a 100% passenger automotive BEV gross sales combine in Europe and 50% passenger automotive and light-duty truck BEV gross sales combine in the USA by 2030.
As a part of the electrification effort, the group is securing roughly 400 GWh of battery capability, together with assist from six battery manufacturing vegetation in North America and Europe.
By the tip of 2024, Stellantis claims it’s going to have 48 all-electric fashions available on the market—principally in Europe— though they’re very intently associated to one another.
