Though Volvo had beforehand mentioned it will not introduce new station wagon fashions, it seems that an about-turn may very well be on the playing cards, because the Swedish model’s new platform may permit its future EV fashions to experience nearer to the bottom, and never essentially be of SUV top, reported Autocar.
The platform often known as SPA3 is first used on the EX60 that made its debut in January this yr, and has been developed for considerably higher engineering flexibility and in order that the car’s battery capability doesn’t dictate the peak of the car, in accordance with the report.
That is doable as a result of the SPA3 platform has been created for EVs from the outset, relatively than being tailored from an ICE-powered car platform, which is the case with its predecessor the SPA2 which underpins the EX90 and ES90, and thus permits extra freedom in transferring parts and constructions to go well with totally different designs, mentioned Volvo chief know-how officer Anders Bell.
His “job in engineering is to supply choices for the corporate,” Bell instructed Autocar. We are able to make [cars] excessive. We are able to make them low. It’s all in scalability and that is unlocked by eradicating the combustion engine, the exhaust, gas tanks and every little thing from the equation, and discovering new methods to construct up the bone construction and the scalability of the platform,” he mentioned.
Packaging constraints for EVs on tailored ICE-based platforms is one purpose why electrical automobiles are getting wider on the whole, as a result of with a view to enhance capability, battery packs must be made wider sideways, Bell mentioned. The SPA3 platform gives new prospects with regard to packaging, which is able to permit next-generation Volvo EVs to extra intently resemble to width, top and silhouette of conventional, ICE-powered automobiles, he mentioned.
When the entrance crash construction of a car has not been formed to accommodate an engine, because the case could be for an ground-up BEV design, there may be extra flexibility to place the battery cells throughout the floorpan, and forward of the entrance bulkhead, and subsequently the battery doesn’t strictly need to be throughout the wheelbase.
The SPA3 platform strikes the assembly level between the battery and the entrance crash construction ahead, so Volvo can put seven kilowatts – at a minimal, most likely extra – of the pack additional ahead, whereas nonetheless doing all of the loopy Volvo crash stuff,” Bell mentioned.
Putting battery cells forward of the entrance windscreen frees up room for “foot garages”, comparable to within the Porsche Taycan and Audi e-tron GT, which permits the seating place to be nearer to that of a standard inside combustion engined automotive. In a decrease automotive, you may depopulate cells within the rear footwell, as a result of that is really what units the bottom top of a automotive: the rear-seat passenger,” Bell instructed the publication.
“When you’ve got an evenly flat pack all through the entire size of the car, you get this penalty. It’s why so most of the [BEVs based on ICE platforms] seem like child SUVs, even when they attempt to be low,” Bell continued. This might, in idea, open the door to the return of a sedan and station wagon sibling to the EX60, although that relies on demand.
“You may obtain this implausible bandwidth so we are able to make super-sleek automobiles, like there’s no battery pack that impacts the peak of the roof,” Bell mentioned.
