- The mixing of a number of parts right into a single drive unit that BYD calls E-Axle was probably the most spectacular half.
- Between the E-Axle and the economies of scale that BYD can obtain, it might promote its EVs at very reasonably priced costs that non-Chinese language automakers merely cannot match.
Japan was once a world chief in electrical and electrified automobiles within the early 2000s, however its lead has since subsided, and it lags behind most developed nations on this regard. China is the undisputed world EV chief today, and the Central Japan Financial and Commerce Bureau organized a seminar that concerned the teardown of a number of EVs to see how others are already so superior.
In keeping with Nikkei, the BYD Atto 3 (pictured) impressed attendees with how reasonably priced it’s given its dimension and specs. In China, the place it’s known as the Yuan Plus, it begins at 139,800 yuan, or simply underneath $20,000, and for that, you get a 201 horsepower EV with a 50-kilowatt-hour battery that offers it a claimed CLTC vary of 267 miles (430 km).

The bigger elective 60.5-kWh battery ups the vary to 317 miles (510 km) for an extra 10,000 yuan or $1,400. This bigger pack can also be provided on the European model of the Atto 3, which prices almost twice as a lot because it does in China. The upper value is the results of each markup and import tariffs, that are set to rise beginning subsequent month.
The Atto 3 teardown in Japan revealed one of many methods BYD manages to maintain prices down and cross the financial savings all the way down to the one that buys the automotive. It’s all about producing as most of the parts as attainable in-house and integrating them. The supply article highlights the so-called “E-Axle” utilized by BYD, which is comprised of eight completely different parts.
It contains not solely the motor, inverter, transmission and controller but additionally the onboard AC charger, the DC-to-DC converter and the battery monitoring system (BMS). This method, mixed with the economies of scale (the bigger the variety of automobiles you construct, the cheaper you may construct them) goes a great distance towards explaining how these extremely competent Chinese language EVs may be offered at such low costs.
The BYD Atto 3 was chosen for this mission not solely due to its worldwide success but additionally as a result of it ranked very extremely within the 2023 Japan EV of the 12 months awards and one other BYD mannequin received.
Kenichi Ito, director of business equipment firm Sanyo Buying and selling and one of many seminar organizers, famous that “Chinese language producers connect nice significance to low-cost manufacturing” and “their views on high quality are completely different from these of Japanese producers.” This was a refined manner of claiming they aren’t constructed to the identical customary, however the market doesn’t appear to thoughts, and BYD offered 300,000 Atto 3s within the car’s first yr of manufacturing beginning in February 2022—it has been doing fairly effectively in some European markets too.
Tesla has an identical method of mixing a number of parts to cut back prices. The most effective instance is the Mannequin Y’s construction, which consists of simply two main items as a substitute of 70 separate components like within the smaller Mannequin 3. Apparently, despite the fact that this protects prices and cuts complexity, Tesla isn’t fascinated by pursuing gigacasting additional and making use of it to different fashions, despite the fact that it commissioned and purchased a few of the world’s most spectacular die-casting presses.
This might be as a result of Tesla’s curiosity has now shifted extra towards self-driving expertise than advancing car-building strategies.
