My current running on i20 IVT is 75 kms per day, thrice a week, to the office and a EV would save some good money on running costs.

But after seeing most of these issues and niggles, I have decided to put this on hold for a year atleast. Last thing I need is running around to fix the issues with service centre.

I don’t find any other EV in this price range appealing. Windsor - I hate the looks, Creta - I don’t see the value, MG ZS EV - Too old. Also I don’t find any of the Tata EVs to be worth paying the extra money over my current car.

So as well I will wait for some new cars or Mahindra to fix the issues. Meanwhile hope something come from VAG stable too. Until then I will bear the extra fuel cost.

The niggles are not as much as discussed in the forum as the negatives are discussed more than the positives. I have done around 1200kms in the last 1 week and have not faced issues till now. Its those whose cars were delivered without the final update are facing the issues I guess. The only thing that isn't working for me, is an apple car play and auto park which I guess I can live without till the next update.

I waited for an EV from the VAG stable since 2020. They have been talking about launching the ID4 for the last 4 years. I then picked up a ZS ev in Aug 2021 and completed around 1.5L in it. Now I picked up an XEV 9E last week. I don't think VAG will launch an EV soon. Even if they launch it, it will be exorbitantly priced around 60L which would loose it appeal. One of the reasons, I've bought the Xev 9e right now is the warranty provided by mahindra for the battery which is 15years or unlimited kms. This might or might not continue like we have seen with BYD which has reduced the warranty to match with other manufacturers. There might be an increase in road tax in Tamilnadu for Ev's since the second extension of the road tax waiver come to an end in Dec 2025. Looking at the TN govt finances, the might impose Road tax to shore up revenue on Ev's above a certain price like Karnataka. The Xev 9e's price might increase around 6L for the top end model if road tax is imposed on Ev's above a certain price range.

I've planned a road trip of 2000km round trip this month. I keep you guys posted with my first long road trip with an EV.

Partially correct. What changes is the extent of the conversion losses. Other than AC - DC conversion, there are other sources of losses as well such as BMS, Cooling systems etc that run irrespective of the amount of energy flowing through.

What compounds it is the fact that these systems are more powerful in a 11 kW OBC to ensure system can handle the higher load. Another source is the thickness of wiring. Higher thickness results in more resistance losses.

On Tuesday and Wednesday (24/25 June) we are in MH.

So when your input load is much lower these overheads create larger in efficiencies.

In fact on a 110v system it's very easy to have 30%+ conversion losses but thankfully we are on 220V in India so such extreme situations don't arise.

So whenever you talk about efficiency losses while AC charging a car, two factors matter: On board charger rating in kW and the input load.

Lowest efficiency will be using the portable charger and that is expected.

Spotted Xev 9e on Pune Mumbai expressway last month. The car looks super sexy on the roads. Especially in white. Road presence is excellent. Was eyeing on Be6. But except for interiors and Price, Xev 9e is much better in terms of Road Presence, Space, Exteriors, Comfort, Spacious boot and Frunk over Be6.

Is there a way to turn off adaptive cruise control and revert to normal cruise control?

Sorry for nitpicking but this statement is factually incorrect. Resistance, and therefore resistance losses, drop with increasing cross section (thickness) of the wire.

Not possible, that’s the only draw back of ACC in my Thar Roxx as it brakes much far away from the on going traffic even when I keep the setting at lowest distance. I would’ve loved if there is an option to only activate Cruise Control but sadly that’s not available.

Has anyone here upgraded or thinking of changing the tyres?

My 9E has the goodyear electricdrive tires which apparently have the foam inside.

I am thinking if 255 or 265 profile tyres Michelin or Pirelli tyres would improve the stance from rear and also be quieter/improve handling/grip? Or are the stock goodyears good enough till the end of life?

That's very sad, mine too just kept braking at every possible thing on the road that tried coming in my lane, making me the slowest car on the road!.

I use cruise control so often in mild traffic that this became a major put-off for me today, the car just won't move!.

Another thing I've not been able to come to terms with is the keyless entry system. It only works on the driver side?!? and it needs the hard push to the door handle to wake it up. From where I'm coming, it was a capacitive touch!

Otherwise, on the car:
On a positive note, the single pedal mode and the ability to use cruise control in stop/ go traffic was awesome.

Everyone in my family is bumping their heads while getting in the car! somehow I don't!

Suspension and ride is super good, somehow the test-drive vehicles were not this good!

Also, I have no issues with my car, so far.

That is how mahindra's adas works. I own a xuv 700 axl and have turned off the adas as it is unusable in our condition. Also you can't use just cruise control because it is adaptive cruise control. You have to turn on adas for cruise control

The stock tires are especially designed for EVs and are extremely quiet. The lack of road noise is one of the highlights of the vehicle. Don’t change them for the sake of it. The vehicle is not undertired in any way.

The ADAS related issues are very much expected in Indian traffic scenarios. Even in Expressways high speed scenarios with less traffic, this kind of braking by ADAS is expected, when there is a swift lane change from a nearby vehicle. The distance to brake might be even too optimized(more) for India.

Imagine the distance being less, and a dog/cow comes in front in a highway, the ADAS brake force might be more and quick, and even if your car brakes safe, there is high possibility of your car being rear ended by another vehicle. So it might feel inconvenient, but its like safety belts being inconvenient for my old parents, they do not know it might save your life one day.

I was using Hyundai Tucson with ADAS in US and even there, there were 1 or 2 close scenairos where my car might have been rear ended due to Adaptive cruise control. I might or might not have braked enough to avoid front end collision in those scenarios, but you never know.

I noticed this on a video of a Be6 user on YT who got 500km from 100-4% SoC, he too showed 7.6 km/kWh, which should ideally mean 576km or in reality the 7.6km/kwh is entirely wrong and it's overestimating by a good margin, with the reality being 6.6km/kwh which is pretty inefficient.

All in all, the car definitely does 500km but a 79kw battery should ideally do 600+

The auto parking in my car works great sometimes but sometimes it just keeps cancelling with the message " space is too less - parking aborted" when there seems to be plenty of space to get into the parking and park. Is there a trick to making it work well?
