Haval " H6 " Dedicated Discussion, Owner/ Fan Club Thread

Once the EV battery is depleted, it's essentially a 1.5T front wheel drive car.

It's locked to 180 km/h and in the video it was hitting 180 km/h with the battery depleted, so what are you talking about?

I've driven several hybrids at 180+ km/h (I say plus because they've all been JDM in the past and their meters don't go beyond 180 so can't tell the speed after that), and they all behave the same way.

And are you seriously saying the performance is not good because it doesn't accelerate fast enough around 170-180 km/h? Where are you even going to drive at that speed under normal circumstances. The H6 is a mid-size family SUV, not a sports car on a track.

PHEVs don't necessarily deplete to 0. Ideally it should reserve some charge and perform like an HEV when battery gets down to that point. This is something Sazgar rep explained on video to Suneel. It's on Youtube on PW channel.

[tech_wiz]

I think the issue is that on motorway if the journey is longer and once battery gets depleted, over taking at 100-120 will become a lot harder specially if you have 4 people in car and luggage in trunk. Occasional breaking will never charge PHEV enough unless plugged at a charger.

[pwuser167550015690]

It doesn't struggle like a non-hybrid 1.5T. You can try that out yourself. In fact, the video even showed that.

It keeps around 2 kWh of battery capacity as reserve instead of depleting to 0 so it effectively becomes an H6 HEV with only sparingly going into AWD, which makes it still faster than the FWD H6 HEV we have in Pakistan. It's reserve battery capacity is still larger than the max battery capacity of standard H6 HEV (1.6 kWh vs. ~2.0 kWh).

[pwuser167550015690]

Again, so many people are misunderstanding how the Hi4 drivetrain in the H6 PHEV works.

When the battery depletes, it doesn't become an H6 1.5T FWD. It still functions as an H6 HEV AWD (a variant not sold in Pakistan).

If you think the current H6 HEV is powerful enough at overtaking 100-150 km/h (I've never had an issue doing that btw) then the H6 PHEV is even better at it because it has more reserve battery capacity and dual-motor AWD to assist.

[tech_wiz]

For a car being marketed as a 4.8 second rocket, it does seem to be struggling once battery goes to that low state of charge. Now sure how much the driver himself is a factor here. Another point is that once on reserve capacity is it able to work in parallel AWD (i.e. power goes to rear motor as well) or in series AWD i.e. works in tandem with ICE to power only the front wheels.

[darthvader]

And are you seriously saying the performance is not good because it doesn't accelerate fast enough around 170-180 km/h?

It slowed down dramatically after 150kph. Where I will need that speed isn't a fair argument because where am I going to need 0-100 of 4.8 seconds? Or 320bhp? Or 750nm of torque? It slowed down probably because it wasn't getting any more power from the electric motor. So what does that suggest about every day usage when the battery is depleted?

My question still stands. What if I'm traveling up North. There's no charging. The battery is depleted after 100km of the trip. Is the rest of the trip going to be on effectively 2WD 1.5L engine power? If that's true then this is extremely misleading.

[darthvader]

When the battery depletes, it doesn't become an H6 1.5T FWD. It still functions as an H6 HEV AWD (a variant not sold in Pakistan).

Is that confirmed? Because the Hi4 version doesn't have a drive shaft. The rear wheels are purely motor and battery driven. Even if somehow they are able to be powered by just 2kw of remaining battery, they will definitely not get anywhere close to the power they would if the battery was charged. I think the BYD Shark suffers from the same problem.

[pwuser167550015690]

Is that confirmed?

Yes. You can even see it in the video you shared. I was just at the dealership but didn't go for a test drive to confirm. Will likely try in a week or two when I go for booking (though I don't know if they'd have a test drive unit with a low SoC).

Even if somehow they are able to be powered by just 2kw of remaining battery, they will definitely not get anywhere close to the power they would if the battery was charged.

Again yes. Almost every electric car looses performance when the battery falls below a set threshold. Usually between 10%-25% depending on how the manufacturer has set it up.

It's just physics. You don't have enough voltage to drive the motors at high RPMs, so you'd have to significantly increase the current to make up for that. But there's a limit to how much current the wires and circuitry can safely handle to BMS typically limits current output.

Doesn't matter if you're a small EV like a BYD Seagull or a Tesla Model S or a performance oriented Porsche Taycan. You gradually loose power and performance as the battery depletes because of a combination of low voltage, current, back EMF etc.

When a manufacturer quotes performance figures for an electric drivetrain, they quote it at the near full State of Charge, and even then only for the dedicated Launch Control mode if the car has one. This isn't Sazgar or GWM doing deceptive marketing. It's the standard practice followed by manufacturers all over the world, and frankly, I had assumed most consumers would've known that. Obviously that's not the case so they need to do a better job at communicating this.

But all that said,

The H6 HEV already works this way with an even smaller battery pack

And I've never heard of (or experienced) any performance issues. So the H6 PHEV is more than capable of sustaining bursts of power even after it drops from EV mode because it still has about 25% larger reserve battery to work with that can power the front or rear motor when needed.

Edit: Btw I didn't have enough time to play with the vehicle settings at the dealership today but it seemed like you can set a limit for the minimum battery level after which it switches to HEV mode (unless I completely misunderstood that menu).

So in theory, if you really want to have lots of reserve battery, you can set it to like 50% and it would start behaving like an HEV after that point.

[pwuser167550015690]

One thing that was slightly disappointing regarding the H6 PHEV was that despite now having access to Coffee OS in the infotainment system, it still didn't have access to GWM's app platform like it does in China, but that kind of makes sense since most of those apps are China only.

Still would've been great if they allowed us to install apps directly from a 3rd party store. It's still Android under the hood so having native Google Maps or Waze or Spotify without having to use Android Auto or Carplay would've been nice.

Also, the delivery times are now 4 months for the PHEV so booking now means you likely get it at the end of December or early January.

Tucson Hybrid Htrac outperformsthis Haval Phev at 120kph .

[ArslanNawaz]

Lol you wish, dream on

[devils_smile]

So o have a issue (you could say) with my facelift hev. The low beams are aligned perfectly. My issue is that the full beam on the passenger side headlight is aimed lower than the one on the driver side. Thus when I turn my full beams on, I have a solid bright light on the road too close to the car which is really annoying. Told haval service center to allign the light properly

Got the car today and despite them saying it's properly adjust, this is what I saw. They've raised the beam on the left headlight from the common adjustment screw found on top of the headlight. This means the light pattern is now in a step pattern. However, even though on a wall, the full beams are now aligned, when on the road, the full beam is illuminating all the left side of the road to the center. Its as if both full beam leds are aimed too left. The full pattern doesn't illuminate anything on the driver side

What am I supposed to do? I do see 2 additional adjustment screws on the back side of each headlight which im assuming are for the angle but now that my full beams are aligned, my lows are in a weird step shape pattern

[kameetaha]

What am I supposed to do?

Park it away from wall like 8-10 feet away and start adjusting by yourself until satisfied.

[pwuser167550015690]

In theory, a repair manual should have outlined what each screw does and you should be able to adjust it yourself as well. But that's where most Chinese vehicles fall apart because repair manuals are extremely hard to come by. I had looked for one a while back and was only able to find manuals for the 2nd generation H6, not the 3rd generation.

[devils_smile]

Did that, at actually 25 feet away from a wall. Those 2 horizontal adjustment screws aint doing anything lol

[pwuser165114417161]

Civic xi has one of the best multi-link suspension setup amongst local cars. Perfect balance of sportiness and pleasure.

[pwuser165114417161]

This is what MG claimed with their phev as well, once the battery is dead it should operate as a normal hev but the fuel average you get within city is less than the normal hev even though you have reserve battery but still the weight of the car and other factors are there which makes it less efficient than a regular hev.

[pwuser167550015690]

On paper, the Tucson Hybrid (both FWD and AWD) should be able to outperform both the H6 HEV and PHEV in acceleration, once all cars deplete their electric power.

That's because of how each of these vehicles generate power. Tucson (and Sportage) are setup like more traditional hybrids where the gasoline engine is the main source of power and the electric motors provide a small assist. Think like how Toyota's hybrid drive system is setup.

The H6 is a modern ("Chinese" style) setup instead where the engine is smaller and the bulk of the power is generated from the electric motors and the engine either kicks in to provide an assist or take over once the SoC is low.

So based on these specs, Tucson has about 60% more power to offer from the engine alone in the even that electric motors can't provide power at all.

But in practice this (probably) never happens. I've never seen my H6 HEV full deplete it's battery* and even when cruising at speeds around 140-150 km/h, if I floor it, I see the motor kicking in provide an acceleration burst as well. The PHEV would be able to do this for much longer because it has more battery to work with.

I've not driven the new Tucson at highway speeds so I can't really say if it works the same but I imagine it does, because that's exactly how my Toyota hybrids worked as well, even though their motor would switch of much quickly.

---

*In fact, when you're cruising at highway speeds, it charges up the battery to near full every chance it gets so that it can provide that burst of acceleration as needed.

[darthvader]

Also notice that the combined power figures for Tuscon isn't just a straight up addition of the power figures of the engine and motor. For Haval they have just added all numbers together for torque.
