Jaecoo J7 PHEV

[Terence2112]

Been driving the j7 for more then a month.

Pumped full tank and charge twice whenever the opportunity arises.

Travelled 695.5km with remaining range of 777km. 
 

not bad if u ask me…

Can share your full tank is how many litres of petrol?

1 full tank is 60L.

With each charging giving about 90km, charging twice would yield about 180km.

With total mileage per charge at about 1400km, the tank of petrol would yield about 1200km. This imply FC under hybrid mode is about 20km/L of petrol which is achievable for most hybrid cars of such dimension such as Camry hybrid which is also rated at 20km/L.

I am curious why you not charging it more to take advantage of the small EV battery onboard. But better to find out from the AD about the replacement cost of the LFP battery in case need to replace after few years of constant charging. I would be thinking to charge it daily if I were to get a Plug-in hybrid unless the EV battery is too costly to replace.

I prefer to spread out the refueling / charging cost to once per month, and stretch to see whether it’s feasible to do it once per month. 
 

The AD provides 10 yr battery warranty and it’s a 1 to 1 replacement in the event it requires to change.

@Terence2112 Did the AD say at what state of charge the LFP high voltage blade battery would be replaced? Will the 1 for 1 replacement occur once the state of charge reaches 70% or less? The concern is that the AD is waiting for the battery to be faulty or the system needs to have a battery fault signal, then the AD is on the hook to do the 1 for replacement of the LFP battery. This is the situation that an MCFer and his BMW PHEV experienced - the AD refuses the replace the high voltage battery even though it's degraded by 60% (i.e. the state of charge is 40%) and he's paying much more now in fuel costs in operating his ride.

If the AD can say with 90% degradation of the LFP high voltage battery (i.e. state of charge at 10%), the LFP battery still works and not at fault - they may consider its not a warranty issue and thus not eligible for the 1 for 1 replacement. That means you can only get 10% of the driving range (or about 8km instead of 80kms) in EV only mode. You'll be spending $$$ in fuel and get less benefits in electric operation / charging.

Looks like good value for money. Motor power is already 150KW with total combined power of 342 bhp, yet the road tax is only $1096, damn worth leh. And the kerb weight is only 1795kg, considered relatively light for a mid-size PHEV SUV.

There's now competition for Cherry's Jaecoo J7 from BYD in the form of the Sealion 06 DM-i. Looks like the AD (Vertex Automobile) had to drop their price! 👍

Competition is wonderful thing for consumers. 😁

Is the combined power really 342hp? For hybrids, its rare to use the peak output of both ICE + EV to derive the total power. With that kind of power (esp electric) and 1.8 tons, the 0-100 should be near 5.x (or 6.x to account for FWD wheelspin) seconds instead of 8.5

Price drop how much?

[Hamburger]

It's a common consensus among motor journalist that Jacoo 7 handling and ride comfort fell short of other competitors.

@13177 Looks to be around $20k from start of this year (2025). See price chart below.

List Price not accurate…. Go to vertex and will be quoted a different price.

The poor ride and comfort of the Jaecoo J7 means it deserves a $10k discount from the competition (i.e. BYD Sealion 6 DM-i). 🙃 Or around $200k region.

Not trying to defend the J7 (although I drive one), but poor ride / comfort is really subjective and depends the ride one previously driven. 
 

Of course, if the previous ride is a Macan, naturally J7 is gonna be bad. If the previous ride is a Vezel, I don’t think it’s gonna be much bad.

On singapore roads, doubt got much difference to be honest. Though of course if lot of roadworks, then road surface quality drops, then  more jittery/soft and suspension flaws can be shown more easily, like the roads affected by NSH now.

City or expressway drive, how much difference can there be.

But everything will be benchmarked to the Juniper now. 
In malaysia, J7 is ? 40k ringgit cheaper than a Juniper. just not in SG.

Yes true. 
In terms of tech, the like for like is the BYD SL6.

Given the complexity of the 4-mode drivetrain (EV, Series Hybrid, Parallel Hybrid and full ICE), good to just pay up and buy some insurance. 

Still find it hard to understand how the Dedicated Hybrid Transmission (DHT) works, probably lots of software and perfect dual motor integration with a single speed gearbox and a clutch. 

This may make more sense than Nissan epower system, which uses a small gasoline engine to charge a battery that drives the motor without the need for gearbox and clutch. But is the technology inherently less reliable than a pure ICE (proven) and BEV vehicle?

@Voodooman The following article explains how the Super Hybrid System (SHS) on the Jaecoo J7 PHEV works: https://paultan.org/2025/08/08/jaecoo-j7-phev-explained-hybrid-with-big-battery-nearly-900-units-sold-omoda-c9-phev-launching-soon/

Essentially below 70km/hr, the J7 is purely driven by the electric motor. Between 70km/hr to 80km/hr the 1.5L turbocharged four-cylinder petrol engine kicks in to assist the electric motor. This is parallel hybrid mode. At above 80km/hr, the electric motor dis-engages and the 1.5L engine drives the wheels. This is similar to what Honda implements in their e:HEV system. Think of Freed or CR-V hybrids.

The high voltage LFP battery pack (18.3 kWh from BYD) always stays above 20% State of Charge (SoC). Once the high voltage battery pack gets to 20% SoC, the 1.5L engine kicks in to re-charge as it's needed to power the electric motor below 70km/hr. This is series hybrid mode operation. 

Claimed combined fuel efficiency is 4.9L per 100 km with the high voltage battery pack SoC at 100%. The fuel efficiency drops to 5.99L per 100km once the high voltage pack drops to 20% SoC. @Terence2112 can advise if this is the case. 

To drive the J7, two conditions have to be met:

(1) The high voltage battery SOC is above 20%; and

(2) Some fuel in the tank.
