Hi John,

The plug-in hybrid model would be very cheap to run if you can keep its battery charged up at home or work to carry out those small local journeys you mentioned, but it will certainly be thirstier than your current diesel on longer drives where you can't charge up the battery from an external source. You'll need to do the maths and decide whether you can actually keep it charged up easily.

If you want us to look for alternatives, come back to us with a rough budget, whether you want a new or used car and the number of people you need to carry regularly and we'll see what else might suit you.

Hi Daniel,

First up, the battery in those alone wouldn't cost in the 10s of thousands - it's considerably less than that. Not that you'd ever want to have to do it, but still, it's worth bearing that in mind.

I must admit we have heard of a few cases where BMW has struggled to identify an issue with the hybrid system recharging the battery and the repair is expensive as it involved replacing the whole hybrid system, not just the battery. That's frightening of course, but it's only a few cases rather than every example of the car.

If you go ahead with the purchase, perhaps consider an aftermarket used car warranty.

If you don't feel confident going for it, come back to us with more information on your budget and needs and we'll try to find you an alternative to your diesel Passat.

Hi Sean,

I drove the Macan 4 at its international launch (read that review here) and today the Audi Q6 e-tron on Irish roads so I can have a stab at comparing them, though bear in mind that both were high-spec cars. The Q6 e-tron I tested was the quattro model using the same two electric motors as the Macan 4, as well as the 100kWh (95kWh of which is usable) battery so these are quite comparable.

The Audi had loads of options though, including air suspension, so that undoubtedly alters how it drives. On that note, the Audi is a little more comfortable than the Porsche, but a little less involving and slower to respond to steering inputs and accelerator inputs. Both are very quiet, refined and smooth to drive, with the Audi slightly better in that regard. The Porsche has fractionally better 'blending' of the friction brakes and recuperation via the motors.

There's nothing to choose between them in terms of range, efficiency and charging capabilities.

Somewhat surprisingly, the Macan 4 has a marginally bigger boot and extra storage under the bonnet included in the price, while you have to pay Audi more to get the 'frunk' insert in the Q6. The rear seats of the Audi feel more spacious, however, than the Macan's.

The cabins are vastly different, but both of very high quality. I prefer the perfectly round steering wheel in the Porsche.

Finally, pricing: the comparable Audi is cheaper than the Porsche and there are more affordable versions of the Q6 e-tron - one with a smaller battery, another with rear-wheel drive - that there are no equivalents to in the Macan lineup.

So as you can see, no clear 'winner' as there are too many variables at work, but hopefully this helps you choose which is for you and your budget. 

Do let us know which one you go for. Both are lovely.

Hi Philip,

A battery in a PHEV (and an EV for that matter) and its various components are no less waterproof or more susceptible to damage in such conditions than an engine and its various components. EVs and PHEVs go through the same stringent quality control checks and have to withstand the same lifecycle as their petrol-powered counterparts.

Hi Catherine,

Stop-start systems can be tempermental. We get so many queries about them that we decided to write a feature explaining the potential issues - Why won't my car's stop-start system work?

Nonetheless, issues with it are regularly caused by weak batteries. Saying that, I wouldn't expect your car to start properly in the morning if there was a big battery problem, so I don't think the boot opening problem is linked to the battery. The Fiat 500 has a known issue where the wiring near the tailgate hinge can become damaged or broken - I suspect that's where your problem lies.

A decent mechanic should be able to quickly fix that for you.

Hi David,

It's a tricky time for choosing a new car in your situation for sure, especially given your high mileage. I feel that a diesel would still be a little more economical for you than the latest hybrids unless you keep your speeds down. If you spend most of that at 120km/h then a good diesel is hard to beat from an economy point of view. Saying that, the Corolla and new Civic are both very efficient cars and, if you adapt your driving style to their powertrains, then it is possible to return some trully outstanding fuel economy figures. And it must be said, with one eye on future values, a hybrid might be a more shrewd choice.

In your situation as described, I'd shy away from purely-electric cars for now as well. I'd be worried about relying on the public charging network to support such high mileage.

Hi Teresa,

We used to get so many queries on this subject that we published a feature called Why won't my car's stop-start system work?

If you read that you'll discover that the systems are highly sensitive to battery charge and load, even when working perfectly. Could it be that you often have high-load items switched on? Things like heated seats, air conditioning, rear window demister, that sort of thing.

Now, in a DSG-equipped automatic car, you shouldn't need to put the car into neutral to get the stop-start system to work - that's only on manual cars. You can leave it in D (drive). What does affect it, however, is how firmly you are holding your foot on the brake pedal when at a standstill. Sometimes it's necessary to give the brake pedal a firm push before the engine will cut out.

Other things to watch out for: if you move the steering wheel, it is likely to cause the engine to restart. And if you're in the Sport driving mode or you've selected the Sport gearbox setting, then stop-start might not work either.

If none of the above changes your experience, I suggest getting a mechanic to come out in the car with you to check it over and observe how you drive, and then let them do the same.

Best of luck with it - come back to us and let us know how you get on.

Hi Nelson,

OK, as ever our answers here include a certain amount of ‘it depends…’ as much does indeed depend on your driving style, the ambient temperature, the cost of your electricity at home and how much public charging you need to do. But, roughly, this is how it should all break down.

Let’s start with the Kona — and by the way, these are both excellent choices as the Kona and the Ioniq 5 are amongst the most impressive EVs on sale right now. Hyundai officially claims that the Kona Electric has consumption on the WLTP test of 14.9kWh/100km, but we’re going to be a little more pessimistic, or realistic perhaps, and assume that you’ll achieve more like 18kWh/100km.

At that rate of consumption, you’ll — obviously — burn through 18kWh of electricity for each 100km you cover. On its undercounted rate for electricity, Electric Ireland will charge you 21.9c per kWh, which means that you’ll pay €3.93 in electricity costs for each 100km journey, assuming you do all of your charging at home.

What if you’re not charging at home? Well… If you’re using one of the new very rapid ESB chargers, which cost 37c per kWh, that cost obviously jumps a bit. In fact it goes up to €6.63 per 100km. If you’re using an IONITY 350kW charger, without a discount or membership, you’ll pay 73c per kWh and that pushes the price up to more than €10 per 100km.

However, the likelihood is that you’ll be using a mix of all three, and maybe you’re lucky and can charge for free at work, so let’s stick a finger in the air and average it out at around €5 per 100km journey. That’s just for the electricity cost.

If you go for the Ioniq 5, then we reckon that you’re looking at more like 20kWh per 100km in day-to-day use, which gives you costs of €4.36 (home charging), €7,37 (ESB rapid charging), or €14.54 (IONITY). Again, all of these prices are to an extent moving targets, and can be reduced further with discounts on charging and home energy bills. Or with free or subsidised at-work charging.

Of course, there are not total life costs. You have to factor in the costs of buying the cars themselves — Hyundai currently has an offer for the Kona Electric of €254 per month on a PCP plan, or the Ioniq 5 at €380 per month.

Those are both for the basic models, but that’s actually OK — the base Ioniq 5, with the smaller battery, is actually quite a canny buy as it will still do a reliable 360km on one charge, and doesn’t look nor feel all that much different to the ritzier versions inside or out. Assuming a reasonable cost for insurance (never an entirely safe assumption to make…) I reckon we can get you in under the €450-per-month mark for either car, with the Kona obviously having a bit more headroom for costs.

The cost of the charging station at home is even more difficult to answer with surety. There is a wide variety of home chargers available now, at various price points, though of course you should be eligible for an SEAI rebate, too. The unknown is if any additional work needs to be done to your house's electrics. Take a read of our Charging your electric car at home feature for a little more detail on that.

Hi Brian,

A diesel car is quite well-suited to that journey still, as it's over 100 kilometres each way, but we can understand why you might be looking to 'electrify'.

First up, I think we can disregard plug-in hybrids for your needs. None of them have an all-electric range to do a full journey from Limerick to Killarney - or vice versa - even if you could plug it in before heading back the other way again. That would make it potentially quite inefficient overall for you.

A regular hybrid might work depending on your driving style. The N21, which I assume you use, is quite a busy road, so average speeds aren't very high, but some drivers do make the effort to overtake slower traffic and keep their average speed up. If you're the type to amble along with the flow of traffic, then a hybrid might get close to your diesel's economy. If you tend to rush and do lots of overtaking, it won't.

Depending on your budget and situation, I think an electric car would be a good option. There are loads of models with official ranges in excess of 400km now and even allowing for a deterioration of that due to higher speeds and cold temperatures, they'll all likely cover the return journey from Limerick to Killarney and back with little trouble. You could top up the battery if you need to in Killarney, but the vast majority of your charging could be done each night at home. That is of course assuming that you have off-street parking and somewhere to install an electric charger. That's key to EV ownership.

If you don't quite need the space of the 5 Series, but like the BMW brand, I'd highly recommend the BMW i4. 

Other than that, check out our list of every electric car currently on sale in Ireland for ideas - and feel free to come back to us to discuss this further. 

Either way, drop us a message to let us know what you decided to do

Hi John Paul,

You’re dead right in that four-wheel-drive EVs are currently rather expensive — the best value ones around at the moment are the Volkswagen ID.4 GTX, the Skoda Enyaq Sportline iV 80x and the Tesla Model 3 Long Range, all of which are in the region of €57,000 to €59.000.  Which is quite a lot of money, even if all three are excellent cars.

If you want to go front-wheel drive, but keep the SUV body shape, then there are still some very good options all the same. The Kia e-Niro, the Kia e-Soul and the Hyundai Kona Electric all share the same battery, electric motor and front-wheel-drive platform, and all are excellent cars. The Niro is fractionally the more practical, the Soul arguably the best to drive and the Kona a pretty good compromise between the two.

Or you could try the MG ZS if you want something a bit cheaper, but bear in mind that a new, longer-range model is coming in the new year that will bump up its price from €28,995 to €31,000. 

Mind you, you’ve said you’re happy to put winter tyres on, and this should really bring the various rear-wheel-drive models back into play. With the right tyres, and given the hefty two-tonne weight of larger models such as the ID.4 and Enyaq, you’re unlikely to experience any major traction issues, so don’t count those models out.
