It's not about EV, it's about BYD

It's not about EV, it's about BYD

What..

 

[Hightech88]

BYD =

Build Your Doom
Bring You Disappointment
Bring You Defects
Bring You Disaster
Burn Your Dreams
Bought? You’re Doomed
Bonus: Yearly Deterioration

But all these complaints are mostly internal BYD models, not those exported so not to worry too much about those in SG..:

---------------------------
There are several structural reasons why domestic China-market BYD cars often show more quality issues compared to exported units — even though they’re the same brand. This is actually a known pattern in the Chinese auto industry, not only BYD.

Below is the real explanation without bias:

​

When BYD exports to Singapore, Europe, Australia, or UAE, they must meet stricter regulations, such as:

• EURO NCAP / ANCAP crash certification
• Stricter battery safety specs
• Higher corrosion-protection standards
• More rigorous inspection before release
• Export-specific QC teams overseeing every batch

BYD cannot afford major issues in foreign markets — one big recall or scandal overseas damages global reputation instantly.

▶ Result:
Export models receive more careful assembly and QC, sometimes even different suppliers (e.g., better paint, better plastics).

​

China’s internal market is extremely price-competitive.
For example:
A BYD Seal in China might cost RMB 180k.
The same car exported to Singapore/Australia is built to a higher spec, priced higher.

Cheaper domestic price → more cost-cutting on:

• Paint thickness
• Rubber seals
• Plastic trims
• Screen coatings
• Weld sealing on underbody
• Electronics QC tolerance

Not “unsafe,” but built to hit a lower price point.

​

Cars in China experience:

• Rougher roads
• Higher pollution → faster paint oxidation
• Northern China: heavy winter salt → corrosion risk
• Southern China: high humidity → water ingress & mold issues

Meanwhile, export markets like Singapore, Norway, Europe, Australia have:

• Better road conditions
• Strict maintenance schedules
• Lower dust and pollutants

▶ More environmental stress = more defects emerging sooner.

​

Because of high competition and volume in China, after-sales service centers sometimes:

• Rush repairs
• Use cheaper OEM parts
• Have less incentive to maintain long-term customer loyalty
• Handle overwhelming volume of EV maintenance (BYD sold millions)

Export markets usually have:

• Fewer cars
• Better-trained technicians
• Mandatory warranty standards
• Strong consumer protection laws

​

Inside China → BYD is seen as a mass-market “people’s car.”
Outside China → BYD is positioned as a premium alternative to Tesla, Toyota, BMW.

To preserve global brand perception, BYD pushes better builds to overseas markets.

Because:​

• Domestic units sometimes get thinner paint coats
• Paint prep (phosphate coating) may be rushed
• Screen suppliers for China-market might be cheaper
• Climate accelerates wear
• Cost-pressure pushes lower-tier components

But when selling to Europe/Singapore:

• BYD uses different factories (e.g., Changzhou or Hefei for exports)
• Tighter inspection at port
• Better corrosion treatment (4–6 layer coating vs 2–3 domestically)

BYD export cars = higher-grade QC + stricter regulations + better materials.
BYD domestic cars = built to lower cost targets, sold in tougher environments.

This is why you hear more long-term complaints from owners in China vs owners in Singapore, Norway, or Australia.

That isn't an electric car.

Its a Extended range Electric vehicle.

Electric car where got engine

It is essentially a EV but with smaller battery packs about 1/3 or 1/4 of normal EV.
And equipped with a ICE engine that runs on a Atkinson cycle that prioritise maximum efficiency to charge the batteries on longer routes.
In urban areas, it uses full EV mode as it has a range if anything between 70-200 km depending on design.
Longer trips, the ICE engine charges the batteries. One tankful of petrols and fully charge car can go 1000km or more.

This type of vehicle is better than just a EV.

So is a hybrid la

Not really .

A hybrid uses EV to assist ICE engine when more power is required. Or act as generator to slow down when stopping. These are what japs and europeans and some Chinese did to their cars.
But newer china models discard this and created a entirely new breed and better way to incorporate both engines. I like this new concept. Only way for japs and Europeans to insert this is by building their cars in china.
