Tesla found a huge, almighty secret when it ripped apart some Chinese EVs, and the discovery changed the manufacturing process within the company forever.

All the juicy details were revealed by a former executive of the brand during an interview with Business Insider.

By investigating beneath the hood and chassis of Chinese EVs, the company brought itself back up onto the high road.

But it may not be what you’d initially expect.

Tesla versus Chinese EVs – the battle of the manufacturing process

It’s no secret that Tesla is the dominating giant in the EV sphere in the US, but the world of Chinese EVs is developing at an even faster rate.

From new battery technology to range increases and pioneering materials, the country is amassing brand new engineering techniques each and every day.

In fact, it’s so advanced that Tesla itself decided it could learn a thing or two when it came to production, and officials conjured up a plan.

They settled on quite literally tearing apart a Chinese EV, and in one interview, former President John McNeill, who took control of the reins from 2015 to 2018, let something substantial slip.

Here’s what was discovered from the exploration endeavour

After cutting into the Chinese EVs, the team found that parts are actually reused from vehicle to vehicle, which lowers the production cost of EVs altogether, which, let’s face it, is good news for all.

“The Chinese engineers are really disciplined about reusing parts underneath the hood that the customer can’t see, and they save a lot of money that way,” McNeill.

We should also note that during the former president’s time in charge, the company was well and truly deep in the trenches of ‘Model 3 production hell’.

But thanks to the discovery of parts being reused, the company wiggled its way out to success.

So, with the EV giant reusing parts, the smart move changed the manufacturing process in Gigafactories worldwide.

“If you tear down all the BYDs – same windshield wiper motor across all of them; same heat pump across all of them; same conduit across all of them.

“In other words, there’s not a team that’s designing a particular model, and they’re off on their own,” he continued.

In fact, it was even revealed that the Model Y shares over half of its parts with the Model 3 and facilitates higher levels of production.
