Current comparison (13-Aug-2025) of hybrids via SG Car Mart with BYD SL6 and Jaecoo J7 leading in terms of upfront and annual road tax costs.

   

Will see what the OMV on BYD's SL6 is going to be when LTA release their figures in mid-August 2025.

Not sure what extra one is getting by paying the extra $56k to Borneo Motors on the Toyota Harrier hybrid? Is the real leather, an extra airbag, 0.4s faster to the century sprint and 3.7km/L better fuel consumption worth $56k more?

[Terence2112]

OMV for SL6 is $24,850

Lower OMV than a Dolphin.

Sure fudged.

Quite surprised about the OMV too. 
Comparing with the J7 PHeV which has higher OMV and retailing at $210k vs SL6 with lower OMV and retailing at $218k, the only reason I can think of is that it’s BYD.

Recently have been seeing many Chinese TikTok on Chinese EV build and parts quality. Can say with all the bloodbath pricing, something has to give. I seriously doubt the chassis can last. They all say the same. What you can see on the surface belies what is unseen underneath.

LTA has released their numbers on cost of cars for July-2025 which includes BYD's Sealion 6 DM-i, as highlighted Terence2112.

Open Market Value (OMV) of SL6 average value is $24.9k (missing some features that's available in other RHD versions in places like Oz) 

Excise Duty (20% of OMV) works out to be $5k

Goods and Services Tax (GST) is 9% of OMV + excise duty, which works out to be $2.7k

Additional Registration Fee (ARF) is a tiered tax based on OMV with 100% on 1st $20k, 140% between $20k to $40k, 190% between $40k to $60k, 250% between $60k to $80k and finally 350% after $80k. For SL6 the ARF comes out to $26.8k. Scrap value would be 50% of this at the end of CoE, so looking at 13.4k on PARF. 

Since SL6 falls in A2 band of the Vehicle Emission Scheme (VES) there is a rebate is a measly -$2.5k.😶

LTA also gives an EV Early Adoption Incentive (EEAI) rebate based on the VES and EEAI not exceeding the total value of ARF, or a maximum of -$15k or 45% of ARF - which ever is lower. For the SL6, there is no EEAI rebate.

OBU cost is $0.16k

Registration fee is $0.35k

1st year road tax (for plug in hybrid) is $1.2k (Nice, don't need to pay the $0.7k EV surcharge!)

Sub-Total of costs including OMV, excise duty, GST, ARF, VES, EEAI and registration costs before Cat B CoE is $58.5k

Cat A CoE (as at 14-Aug-2025 and reported on SG Carmart) is $123.5k

Thus cost basis before Sime Darby (Vantage Automotive) AD mark up is $58.5k + $123.5k = $182k

Current sales price as reported on SG Carmart on the SL6 is $215.9k with strings attached. If one goes for an all cash deal, there is a financial penalty of an additional $6k. So all cash deal price = $215.9k + $6k = $221.9k.

Sime Darby (Vantage Automotive) and dealer mark up is $39.9k or 160% of OMV value on the SL6. So yeah, Sime Darby, Vantange Automotive and it's dealers are making nice fat (i.e. triple digit) margin on each SL6 sold. It's a lucrative business to be a new ride seller in Singapore.

Don’t understand why the SL6 road tax is higher then J7, despite J7 having a 1.5T engine. 
 

SL 6 - $1,170

J6 - $1,096

or is there a typo?

For hybrids it is a combination of engine + power output. Sealion 6 is slightly more powerful than Jaecoo J7.

SL6 is more powerful? I thought J7 is.

The J7 advertised combined hp number is a straight addition of its EV and 1.5 ICE. Jaecoo is being obscure with the numbers.

As I stated before, if its really 350ish hp, it will be a 5 or 6 second car.

Agree… but if we look at it separately, the respective figures for j7 as compared to SL6 are more as well?

Crash test results for BYD Sealion 6 DM-i from ANCAP.

Adult occupant protection: 88%

Child occupant protection: 86%

Venerable road user protection: 83%

Safety assist: 75%

Overall, the Sealion 6 DM-i got a five star safety rating.👍 More details are available here: https://howsafeisyourcar.com.au/byd/sealion-6/2024

 

[steveting99]

The SE has confirmed that the high voltage battery pack used in Sealion 6 DM-i is the older blade battery and is the type CB4A. Battery curve of CB4A is shown below.

Since BYD offers a 10 year, 200,000 km warranty - it's worthwhile to check the State of Charge (SoC) of the high voltage battery when carrying out regular maintenance. Get in writing from the dealer that once the SoC drops below 70%, BYD, Sime Darby and the dealer would replace the battery pack if its still within the warranty period. Don't let BYD, Sime Darby and the dealer worm their way out of their warranty obligations by saying there's no fault reported by the high voltage battery pack system and thus there is no warranty claim. See an example below from MCFer (eleong) bad experience on his 2019 BMW225xe PHEV's degraded high voltage battery pack with BMW dealer (PML) here: 

 

Unfortunately eleong isn't the only one who's experiencing degraded high voltage battery pack issue on his PHEV.

Wow BYD dealers are licking their fingers on these crazy margins.

Vehicle breakdown analysis in Europe's largest vehicle market (Germany) by Europe’s largest automobile association Allgemeiner Deutscher Automobil Club (ADAC). Report is here: https://presse.adac.de/meldungen/adac-ev/technik/adac-pannenstatistik-2025.html

ADAC carried out 3.6 million breakdown events in 2024 and found that ICE vehicles broke down 9.4 vehicles per 1000 unit compared to 3.8 EVs per 1000 units. Comparisons are of vehicles of the same age, i.e. 2020 ICE vehicle vs. 2020 EV. The vehicles are relatively new from 2020 to 2022 with age range between two to four years.  

ADAC says EV's are 2.5x less likely to breakdown compared to ICE vehicles. 

There are some variability amongst manufacturers for both ICE and EVs. Surprisingly Toyota C-HR, first registered in 2020, has 63.1 breakdowns per 1,000 vehicles is the worst of all. On the EV side Hyundai's IONIQ 5 has 22.4 breakdowns per 1000 units due to problems with the integrated charging control unit (ICCU). The stars of the report are the Mini (0.3 breakdowns per 1000 units) and Audi A4 (0.4 breakdowns per 1000 units) which are on ICE side. On the EV side, the Tesla Model 3 is the star with just 0.5 breakdowns per 1000 units. 

Most of the breakdowns are due to the defective starter battery (contributing to 44.9% of the 3.6 million breakdown event). Looks like replacing the standard 12V lead acid battery with a more reliable 12V lithium ion battery is a simple way to improve reliability.  

In EU, the SL6 DM-i is re-branded as the Seal U DM-i. Similar to Tesla, SE says that for all 2025 models (and beyond) BYD will no longer have lead acid 12V battery and instead will have LFP.😃 This will improve overall reliability and minimize breakdown events in the future for BYD owners. 🤙
