Does the Toyota Aygo X hybrid have 12-volt battery problems?

Has the new Toyota Aygo X overcome the 12-volt battery problem of the Yaris which goes flat if you only do short journeys? This is a nightmare for low-mileage users.

Hi Jean,

We don't believe anything has changed on that front to help alleviate the situation.

The 12-volt battery in Toyota hybrids is not charged by an alternator turned by the engine as it would be in a traditional petrol engine. Instead, its charge is maintained by the hybrid system itself, via a DC-DC converter, though this is not done particularly quickly – and can only be done when the car is 'running' (even with the engine off, but with 'READY' showing in the instruments).

Unfortunately, during lots of short journeys, with relatively more opening and closing and other drains on the battery, there isn't enough time for the system to keep up with the discharging of the 12-volt battery. This is exacerbated by the fact that these cars use a much smaller-capacity battery than an equivalent petrol car would to start with, so they have a lot less in reserve.

It's not ideal, but the advice is to make sure the cars get a longer run periodically.


VRT on a Skoda Octavia RS from the North?

Hi.

I was looking to know how much it would cost to VRT a 2016 Skoda Octavia vRS - the car is in Northern Ireland. I am from Northern Ireland but have moved to the Republic of Ireland in recent years. Is there anyway this helps to get it cheaper?

Hi Stephen,

First up, I'm afraid your previous residence in the North can't help you if you've moved south years ago. There is a "Transfer of Residence" scheme in place that allows you bring your car with you when you move, but it can't be done years after the move.

We need the OMSP (Open Market Selling Price) and the VRT band to do the calculation - and this is just an estimate. The OMSP is the value Revenue believes the car to be worth in Ireland after registration, so that's not a fixed thing. Let's round it up to €20,000 for the sake of our calculations.

You didn't state whether it's petrol or diesel. In both cases the CO2 rating from 2016 will have to be 'uplifted' to align with the newer WLTP scheme. We believe the petrol model would be in Band 18 (156-170g/km after uplifting) at 30 per cent of OMSP and the diesel would be in Band 16 at 25 per cent. 

The former then would be €6,000 VRT and the latter €5,000 - if the OMSP is €20,000.

Do not forget that you will also have to pay the NOx levy on top of all this, which will be way more expensive on the diesel model.


How much to tax my Australian Mitsubishi ASX?

How much tax will I pay for a Mitsubishi ASX 2.0-litre petrol automatic which I brought back with me from Australia where I lived for 13 years? The car is 2017 and I owned it since 2019. Has passed the NCT.

Expert answer

Hi Ciara,

We need the CO2 rating to determine the motor tax.

According to our data, that car's original CO2 rating would have been 176g/km, but that was on the old "NEDC" system and when a car is imported into Ireland now its CO2 figure is 'uplifted' by Revenue to align it with the newer WLTP scheme. Doing that would raise your ASX's rating to 197g/km, which would mean motor tax of €790 each year.

The importation paperwork should have shown which CO2 rating the car now has according to Revenue so you can check it. If it's not the above figure, look up the motor tax on our Motor Road Tax Prices in Ireland Explained feature or come back to us if you have other questions.


Why do you classify hybrids as electric cars?

Why do you classify hybrids as electric cars? I'm not talking plug-ins, in which a case can be made. I mean non-plug-ins, which take all their power from fossil fuels - no part of their power comes from clean sources.

So the latest stats say 54-per-cent increase in sales for electric cars, but a high proportion of that is for hybrids that take all power from fossil fuels.

I have no doubt the government wants to label them as electric as it helps them in their delusional expectations that we will get to 100 -per-cent electric by 2030. But surely it is the job of journalists to state, and push for, the truth rather than push a narrative?

I'm not saying you should call them petrol/diesel but they are definitely not electric cars.

I'm not anti-electric, I'm much more for the right technology for each individual. Electric doesn't suit my use until megawatt charging (or hydrogen refuelling) is the norm, but I have suggested to others to go electric as suits their use. But I find the pro-electric push annoying and frustrating, particularly from journalists.

A 600km range is great, but a 30 to 40min recharge time (in ideal circumstances) is ridiculously slow. I can add 1,000km range to my diesel in four minutes. And no, like alot of people in cities I can't charge cheaply overnight as I don't have a garden.

Expert answer

Hi Diana and thanks for this message.

I'm a little perplexed by it though as we quite strongly believe that hybrids are not electric cars and should not be classified as such. The latest SIMI figures on this page state a 52 per cent increase in the number of EV registrations, and that is indeed fully electric cars. That figure does not include hybrids of any sort.

And likewise, we're not pushing any EV agenda - we've always maintained that we're 'powertrain agnostic' and happy to help buyers choose the car that suits them. Our content may appear skewed towards electric cars today as there are more EVs than ever for us to drive, but we're as happy to recommend a diesel if that's what the buyer wants.


Looking for a second car for up to €15,000...

Hi there,

I'm looking for a recommendation for a second car for short journeys with two children, i.e. ferrying them to weekend activities. We're in two high-back child seats at the moment and the eldest could go in a booster seat to save space if needed.

Occasionally we might also use the second car to transport fitness gear for classes I host; this can fill a good bit of our 520-litre boot so might require folding the rear seats of a smaller car.

If combining these needs is too much of a trade-off though, we could continue to use the main car only for this purpose and have the second car only for the kids activities, basically.

A third wrinkle would be that it'd like to be able to transport one bicycle on the second car, with a roof- or boot-mounted rack.

Our main car is electric, and we have a home charger. We're so used to it I imagine it would be hard to go back to a manual transmission, but I'm open to petrol, hybrid or electric for the second car.

Budget around €10-15k. Would probably prefer something newer rather than an older model in that price range.

Hi Martin,

We wish all readers were so detailed in their requirements, as it makes it easy to choose a suitable car for you.

In your position, I'd be inclined to buy as new and long-range a used Nissan Leaf as I can find to use as your second car for ferrying the kids about. It's not huge inside but should be grand for a couple of child seats in the back so long as the front-seat passengers are not really tall.

It'll be exceptionally cheap and easy to run as you already have a charger at home and maintenance will be minimal as well.

And you'll get a bike rack on any car within reason.

If you'd rather not have another EV, then perhaps consider a large hatchback such as the Skoda Octavia. It's massive inside and in the boot so could fill in all the gaps you've mentioned, and there are plenty of different models available, including plug-in hybrids, so it might offer you an extra dimension of versatility, but with the option of keeping your costs low at the same time.

Come back to us to let us know if we're on the right track (you can submit another question or send us a private message via the Contact Us page).


How much VRT on a petrol Skoda Octavia RS from the North?

Hi,

I'm looking at buying a 2022 Skoda Octavia vRS 2.0-litre petrol from Northern Ireland. It has 46,000 miles on the clock. I'm just wondering how much VRT would be on this.

I've rang Revenue but they wouldn't give me a value because it isn't listed on their system so they said they would have to bring an outside vendor to value it. I have tried the VRT valuation site which I had to pay for, but I found the valuation to be a bit low, between €3,500-4,500.

Now it would be great it that is what the VRT is but I'm just worried about buying it and being hit with a big VRT bill.

I would appreciate any help with this please.

Hi Derek,

We can only give you another estimate, I'm afraid, as there's no way to know what Revenue will actually value it at when it comes to its inspection.

There's a similar car on sale on Carzone as I write listed at about €37,000. Taking that as the OMSP (Open Market Selling Price) and the CO2 output putting it into Band 18 for VRT (156-170g/km) at 30 per cent of the OMSP, then the VRT bill would in theory be €11,100.

That's before the NOx levy, though it's only a few hundred Euro on a modern petrol car such as that.

Adjust what you think Revenue will value the car at (the OMSP) to see what effect it has on the VRT calculation, but I agree with you that €3,500-4,500 seems low and you should be prepared for more.


Looking to bring in a Lotus Elan through the North...

Hi,

I need advice please on importing a 1991 Lotus Elan to Southern Ireland using an intermediary address in Bangor N Ireland.

I heard that the Windsor Agreement permits a car to come into NI for a few months to be insured and MOT'd there and after a few months brought into to South of Ireland avoiding VAT providing there is proof of use there, ie petrol receipts. Is this correct?

Christopher Hayward (Kinsale, Co. Cork)

Mar 2026 Filed under: importing

Expert answer

Hi Christopher,

That is mostly correct, though the car must be registered to someone at the Northern Irish address and I don't believe that petrol receipts will suffice as proof. An MOT in the North should though. Revenue isn't very precise in its information around this, unfortunately.


What will I replace my Peugeot with for €15,000?

I'm looking to trade in my 2012 Peugeot 308 Active HDi (with 242,000km on the odometer) for a newer medium-sized used car and don't know if I should be looking at a diesel, petrol or a hybrid car.

Reliability, efficiency and easy maintenance are my key concerns. I travel mostly rural roads and do a short daily commute (50km per day round trip in low density traffic). I sometimes take longer trips but rarely use motorways. My annual mileage is roughly 20,000km. My budget including trade in would be in the region of €14-€15,000.

Expert answer

Hi Mary,

A diesel would probably continue to give you the best economy given your usage, but we'd worry about long-term maintenance for sure as modern diesels have expensive components that can get gummed or clogged up.

If you're willing to make that compromise, then you could do a lot worse than a 2018 Honda Civic 1.6 diesel. Lovely car. It also came with a 1.0-litre petrol engine, but it has known 'wet belt' issues so we would not recommend it.  

You could afford a 2019 Hyundai i30 with either a 1.6-litre diesel or a 1.0-litre petrol engine and that's a very good bet in terms of reliability. Same for the related Kia Ceed, though they're rarer.

Even less common is the Mazda3 of the same year. It's a lovely looking car, of great quality and though it comes with a 2.0-litre petrol engine, it's an efficient and reliable option.

If you liked your Peugeot, you could move up six or seven years to a newer 308, though best to stick with diesel if you are doing that as the 1.2 'Puretech' petrol engine can have wet belt issues like the Honda.

One of the last of the Renault Megane hatchbacks is another good option, available with petrol or diesel power depending on your preference.

The SEAT Leon is possibly our favourite find for you at this price point with good petrol and diesel engine options and great comfort. You can't ignore the Skoda Octavia for the same reasons, and it's even bigger.

Lots to think about there so come back to us and let us know if we're on the right track. We've only selected mid-sized hatchbacks, while there would be plenty of crossovers and small SUVs in budget as well.


Will I stick with diesel as I do some towing?

I own a Mazda CX-60 diesel and changing this year. I drive short distances but occasionally do some towing. What's best option, diesel again or petrol hybrid? A bit scared of going hybrid.

Francis (Ireland)

Mar 2026 Filed under: towing

Expert answer

Hi Francis,

Towing is certainly one of the strong points of diesel power with their low-down torque, but any hybrid with a big electric motor should be good too thanks to the instant-torque characteristics of the motor. For example, if you like the CX-60, Mazda does a plug-in-hybrid version with the same towing rating. You may find it difficult to find a non-plug-in hybrid to match the same rating though.

Come back to us with your budget and the weight you need to be able to tow, and we'll take a look around for other options for you. And let us know if you're willing to consider a PHEV.


Does the Macan S have a proper Porsche engine?

I used to have a diesel Porsche Macan, which I later learned was powered by a Volkswagen engine and I had loads of trouble with it.

I currently have an aging Panamera Turbo with a proper Porsche engine which has been faultless and I am thinking of changing.

Is the 3.0-litre V6 petrol engine in the Macan S a Porsche development?

 

John Moseley (Bs25 5nt )

Expert answer

Hi John,

The early Macan S certainly used a Porsche-developed engine, and even the later examples were hardly just Audi/Volkswagen engines with a different cover. 

Not that every engine Porsche has developed itself is reliable, but that V6 is generally solid so long as it has been maintained properly.
