MEB platform cars have known 12V battery issues and also the occasional bad steering vibration when reverse gear and also only 8 years battery warranty. MEB cars include Audi Q4 e-tron, ID.4, ID.5 and Cupra Born and Tavascan. I was close to pulling the trigger on the Tavascan but got put off by these reported issues (i joined the FB owners clubs for other countries). Oh and they ALL have rear drum brakes (incl Q4ET). 

No car is perfect, EVs are no exceptions. I will definitely report here if my ride has encounter any issues that was flagged out before worldwide. 😃

Regarding drum brakes, I did "test" on 1 occasion when I was accelerating to 60kmph when some idiot filtered abruptly into my lane without signalling, the ABS kicked in and braked to a stop. Anyway, some prefer disc brakes in the rear, some (like me) do not need.

In my mind drum brakes are only found on those very B&B/budget cars....and when u are paying $200k++ for a conti.... u at least deserve disk brakes, not really a question of whether need it or not. And Cupra being a "performance" brand, its a particular shame....

EV has regen brake.  May not need rear disc.

Cosmetically, it looks bad against Previous Gen Jazz which is 4 wheel disc and 130hp

Yeah that's what VW Group's position is. But as I said, it's not a matter of need (after all there are many other things in a car that we don't "need"). As per ur example, many basic cars also have disc brakes and of course most other EVs also have rear disc brakes. They just wanna cut corner.

@marcuspeck thanks for the comparison and congrats on getting the Enyaq! The Skoda Enyaq sure looks interesting and the has a fantastic WLTP range of 585km which easily beats the Sealion 7 WLTP range of 480km. Interestingly both have approximately the same battery size of 82kWHr and both vehicles weigh the same around 2.2 tonnes. The efficiency of the Enyaq is a bit better at 19.2kWHr/100km compared to Sealion 7's 19.9kWHr/100km. That 4% energy efficiency still doesn't explain 21% range difference - which me scratching the head. Was trying to find out what type of lithium ion battery the Enyaq uses and not so easy to find out using Mr. Google. Either it's NMC, NMA or LFP. The Sealion 7 uses BYD's proprietary blade battery which is LFP type. Does the Enyaq owner's manual state the battery type used? A clue would be the recommendation in the owner's manual on the cut off while charging - is it 80% State of Health (SoH) or does it say to regularly top up to 100%?

Skoda does a few things right compared to BYD for the end user. This includes some physical buttons below the infotainment display, the front door storage compartment for an umbrella and rear seat shades.  One thing that Sealion 7 has that Enyaq doesn't have are the ventilated front seats - quite useful in the hot climate of Singapore. 

An important point to consider between Enyaq that Sealion 7 is the manufacture's warranty. Skoda Singapore offers a shorter 2-year manufacture's warranty with unlimited kms. BYD Singapore offers a longer 6 year 150,000km manufacture's warranty. If Skoda can match BYD's manufacturer's warranty period of six years, it would be better and give future car buyers a lot more confidence in the product. 

Rest of the features between Sealion 7 and Enyaq are about the time - so it's down to price and what one thinks are important features (i.e. personal preference).    

2 years warranty? Seriously what the hell is Skoda/VW thinking? This speaks volumes on the confidence they have of their own products.

I find the discussion pretty interesting about VW group's MEB platform equipped with rear drum brakes. The decision to go with rear drum brakes may be unfairly criticised by most people as a pure cost cutting move. There is no doubts that drum brakes are mechanically simpler, more durable and cheaper to produce. 

However, in the case of EVs, you will have to consider the following points on why its actually not that bad of an engineering alternative,

- EVs do regenerative braking by the combination of its electric motor as well as friction brakes (discs or drums). Since the electric motor is also capable of slowing down the car by regen action, EVs don't have to rely on its friction brakes that much to generate sufficient stopping force. And most modern EVs also do something like brake blending, which means the car automatically decides to activate its friction brakes, electric motor or both at the same time to slow down the car if the rate of deceleration warrants for it, especially if you're doing one pedal driving

- Also because you're doing more regen braking thru the electric motor, heat dissipation is less of an issue. And heat dissipation is one major advantage of discs over drums, and this is not really an issue for an EV as the motor is doing most of the braking 

- Precisely because EVs don't use its friction brakes that often, brake discs and pads will be more prone to corrosion, oxidisation and seizure (pads sticking to the disc rotors). In certain weather conditions, your rear pads may stick to your rear disc rotors if you engage the parking brake and park overnight

- So drum brakes while at 1st glance is a cost saving solution, its simpler and much more robust and durable design may actually be better for an EV in the long run

Has anyone taken a look at the Skoda Enyaq's rear drums? These are huge drums man, I don't think the stopping power is compromised that much. The wheel size below is 20", so drum is pretty big to compare its relative size vs the wheel. 

Before anyone accuses me of being a VW/Skoda salesman, I'm sorry I'm not as I'm driving an EV from Volvo that has 4 full discs all around 😂

its purely a cost cutting move no matter how one spins it. to say performance is good as disc is kidding oneself...

In certain weather conditions, your rear pads may stick to your rear disc rotors if you engage the parking brake and park overnight

all disc and drums will have pads/shoes sticking due to corrosion. but will clean up after you move off and apply brakes within a couple of meters. never been a problem.

- So drum brakes while at 1st glance is a cost saving solution, its simpler and much more robust and durable design may actually be better for an EV in the long run

drum brakes are also more difficult to service than disc and caliper. i DIY my own front disc. but have never done the shoes as need to adjust spinning adjustment wheel and also to remove the spring

I am sure it serves the purpose otherwise they would be exposing themselves to huge risks. My point is at this price point, can't they do better? As far as I know, no car above OMV $20,000 has rear drum brakes. And personally, i don't find large drum brakes to be something i would find attractive. It was because of this that I would have stuck to the Cupra's stock rims as they cover up the drum brakes (but washing the inner barrel of the rims would be almost impossible as the openings are very small).

 

 

[Lethalstrike]

I understand there's 2 camps with regards to rear drums on a $200k Conti car.

I can also totally see why some felt that rear drums are a blasphemy, but I also think that its also correct to point some advantages of such a design to everyone else reading this thread. 

I never had to service the rear drums of my very 1st Jap hatchback bought back in the early 2000s. Who knows maybe this Skoda Enyaq's rear drums need some special shoe pads or something? 🤣

If you are coming from an aesthetic and "they can do better" POV, then yes I will agree with you.

Putting all other engineering considerations aside.

When i get my EV i will turn off (or minimise) the regen braking so i can't (and don't want to) rely on regen braking. If i end up with an MEB car (i have not ruled it out), i would likely upgrade my front brakes to a 6 potter...

Regen brake is more efficient than mechanical.

It saved me a couple of time in a China Van.

I feel bad to say but i have convenient access to unlimited charging at a low flat rate so for me i don't really need the regen to extend my range....

model 3 regen is good. Tested up and down mountain with minimal use of brakes.

No offence but I rather take public transport than drive a tesla. Even before he became Trump's lackey.

Having said that, the 2nd gen design is much nicer (no more fish mouth in front) but still no thanks.

Most EV is brake-by-wire.

It is still regen before mechanical.

Reduced regen is just allowing the car to coast longer.

I only know less regen is less "jerky" 😅
