The Tesla teardown taught Toyota that the Japanese automotive firm’s famed designed-for-manufacturing experience had been one-upped in some ways. The newest variations of the Model Y, Toyota found, appeared the identical on the skin however had been utterly revamped beneath.
Tesla’s use of giga casting eradicated numerous elements and brackets by basically casting the automobile’s back and front as two big modules.
Also, as an alternative of plunking the battery right into a body between the axles, the newest Tesla battery format acts structurally as the ground itself.
By one Toyota estimate shared with Automotive News, Tesla’s method eradicated tons of of elements and as much as 220 kilos, whereas boosting the automobile’s battery vary and slashing overallcosts.
“It’s a whole different manufacturing philosophy,” one government stated.
“We need a new platform designed as a blank-sheet EV,” stated one other.
Caresoft Global Technologies, a Michigan-based engineering firm that does digital and bodily benchmarking and price reductions, reckons full-EV startups similar to Tesla have a major first-mover benefit as a result of they rethink engineering challenges from scratch.
Tesla, for instance, changed the business’s conventional 3.5 mm thick powertrain cooling hoses with 1.5 mm ones manufactured with a lower-cost materials. Tesla was ready to take action as a result of the cooling fluid for electrical automobiles would not get as sizzling and doesn’t must be as extremely pressurized to forestall boiling as it’s used for inner combustion engine cooling.
In some automobiles Caresoft has analyzed, that saves a minimum of $25 and 11 kilos per automobile.
The similar method applies to Tesla’s frunk, utilizing the entrance engine bay for trunk house whereas hiding away such parts because the inverter beneath the rear seat.
Legacy makers similar to Toyota and Nissan, even of their newest EVs, nonetheless pack the previous engine bay space with parts, doubtlessly lacking a possibility to wow prospects with new options.
“It’s that outside view of not being part of the industry,” Caresoft CEO Mathew Vachaparampil stated of latest EV makers. “An outsider typically disrupts the traditional industry with a better idea.”
