A few questions on the new Toyota Aygo X hybrid...

Hi,

I'd like to know a bit more about the Toyota Aygo X hybrid.

1 – Tell me about the wheel and tyre sizes. Reckon the 18-inch, low-profile alloys would get wrecked in a pothole?

2 – Is there good ground clearance for country roads?

3 – How far does it travel on just the battery power?

4 – How big are the digital screens?

5 – Does it have Google built in?

6 – How economical is in reality?

7 – What's its coefficient of drag?

Hi Patrick,

We'll do our best to answer your questions, though you may be as well off to pop into your local Toyota dealer to talk it over and take the car for a test drive yourself.

1 – The 18-inch wheels are only available on the GR Sport model and yes, they will be more susceptible to damage than the 17-inch rims fitted to most versions, but not drastically so.

2 – Yes, the tall wheels help give the Aygo X higher ground clearance than most small hatchbacks, that's for sure. It's not an off-road vehicle, though.

3 – There is no official figure for how far the hybrid Aygo X will travel on battery power as it only has a small battery, and it is not a plug-in hybrid. The system shuts the engine off regularly when driving in slow traffic. Though there is an “EV mode” button to force the car to use the battery charge, there's no reliable way to observe how far it travels on purely battery power for a single charge of the battery.

4 – The entry-level touchscreen measures nine inches across the diagonal, while a 10.5-inch screen is available on the higher specification models.

5 – No, Toyota does not use a Google-based operating system in the Aygo X. If you want Google Maps then you'll have to use Apple CarPlay or Android Auto in conjunction with a smartphone.

6 – We managed to beat the official fuel consumption figure – of 3.7 litres/100km (76.3mpg) – recording 3.2 litres/100km (88.3mpg) on a day of mostly slow enough driving, but including one section of motorway.

7 - The coefficient of drag is 0.31.


Could I get a spare wheel for a new Toyota Aygo X?

Would a spare wheel still be an option in the new Toyota Aygo X hybrid as the auxiliary battery has been shifted under the boot floor? Looking at getting a Yaris, or Aygo if there is a big price difference between the two.

Hi Nuran,

I'm afraid not. The car is not designed to accept a spare wheel. 


Am I better off with a diesel BMW X3?

Hi guys,

I am currently driving a 241 BMW X3 M Sport plug-in hybrid - I traded up from a diesel 191. And I just don't like it! It is costing way more to run than what I was forking out for the 191.

I love love love X3s but I am wondering would I get better value if I went with the diesel hybrid? I do a lot of miles, as well as small bit of city driving, but mostly 100km a day. What would you think?

Expert answer

Hi Elaine,

The BMW X3 diesel is what's called a "mild hybrid", so it can't be plugged in. The plug-in hybrid only makes sense if you can plug it in at home to charge up the battery at every available opportunity. If you don't do that then it's essentially the same as fuelling a heavy petrol-only model.

In general, a diesel car is more efficient than a plug-in hybrid when it comes to long journeys and it sounds like that's what may suit your needs better.


Which BYD models will get the new Blade batteries?

BYD 'Blade 2' batteries will be available in what models?

Expert answer

Hi Paddy,

BYD has not announced any models for Ireland using the second-generation Blade battery, and indeed it hasn't really confirmed which cars will definitely get such a thing anywhere in the world that we know of.


Does the Aygo X get the same battery as the Toyota Yaris hybrid?

Will the new Toyota Aygo X have the same 12-volt battery as the Yaris hybrid? It has been reported that the 12-volt battery gets drained if the car isn't driven regularly.

Nuran (Birmingham)

Expert answer

Hi Nuran,

This is a challenge that affects a lot of modern cars, not just the Yaris hybrid and the issue here is not the battery itself, but the entire system that takes energy from it.

The Aygo X's electrical system is very very similar to that of the Yaris so, unless Toyota has made changes to reduce the chances of the 12-volt battery draining while the car is left idle for long periods, we'd have to assume that the Aygo X also needs to be regularly started up to avoid issues.


Which new EV for up to €45,000?

Your recommendation for a new electric car please: mid-sized, suitable for four-five long-distance trips per year, otherwise light city driving. Comfort and performance a priority and also range.

Hi William,

There are plenty of good new EVs on the market within budget to consider, though most are crossover or SUV-style vehicles. That's a good thing in terms of ease of access, as their door openings are usually large and the roofs are not too low. It also usually means a relatively high-set seating position, to the benefit of comfort and visibility.

We prefer to drive regular car-shaped vehicles, but there just aren't enough all-electric options, unfortunately. While there's some negativity towards SUVs in general, we reckon a compact electric SUV ticks a lot of boxes for a lot of buyers, while not being completely inefficient.

Before giving you a few potential EVs to book test drives for, I'd urge you not to focus on the range too much. Assuming you can get a home charger installed, then going by your usage as described, you'll do the vast majority of your charging at home.

Prioritising a longer-range car means getting one with a bigger - i.e. heavier - battery, which will cost more up front and result in worse efficiency day to day. Relying on the public network a few times a year is no reason to compromise your car for the rest of the time.

The first car to come to mind is the excellent Renault Scenic E-Tech electric. It's probably bigger than you need, but the long wheelbase helps with comfort, and it sits somewhere between a hatchback and an SUV in terms of design and shape. With your budget, you could probably get the larger (87kWh) battery pack or choose the smaller one and a higher specification.

Sticking with Renault for a moment, another cool option is the new Renault 4 E-Tech, launching in Ireland imminently, though it doesn't have as long a range as the Scenic.

If you can wait a little, then it's also worth considering the new Nissan Leaf. This is a really excellent car that will certainly be in budget. It's quiet and comfortable to drive and efficient, too. The Nissan Ariya is already available, but I suspect it's larger than what you were looking for. It is comfortable, though, so no harm test-driving it for yourself.

The Hyundai Ioniq 5 is another great option, with a fantastically comfortable interior, good efficiency and a decent range for the money.

I could go on and on, so let us know what you think of these by submitting another question and we'll try to narrow things down for you.


What's up with my Peugeot 307 HDi?

My Peugeot 307 HDi wagon (370,000km on the clock) still runs beautifully but comes up with various faults. Some cause it to derate, others cause the cruise control to not function. Examples include turbo overboost, EGR sensor malfunction, depollution system faulty, air-conditioning refrigerant low, electronic circuit high voltage, etc.

Any word on what could be causing all this?

I am totally lost as to how to stop this occurring.

Expert answer

Hi Jon,

At that mileage, your car is likely suffering from voltage fluctuations and ageing wiring and connectors, all of which can lead to the issues you are describing. 

I'd suggest you go back to basics and have the battery, alternator and each and every earth connection checked and cleaned for starters. Then plug the car into a diagnostic computer (any good mechanic can do that) and clear the faults before driving it and plugging it in again to see what comes up.

Some common 307 HDi issues we know of:

- Boost control solenoid
- EGR valve or position sensor
- BSI (Built-In Systems Interface) can act up with water ingress or voltage surge

In summary, there's unlikely to be a simple fix to this, but it's almost definitely electrical.


What warranty is there on a Volvo XC90?

What's the guarantee on the car, battery and air suspension for the Volvo XC90?

Tony Cahill (Dublin)

Aug 2025 Filed under: warranty

Expert answer

Hi Tony,

The standard warranty is three years or 150,000km on all components, including the air suspension. The battery is actually covered to eight years, but that's also capped at 150,000km. There is a 12-year anti-perforation warranty as well.


What's up with my Fiat 500?

I had my Fiat 500 looked at as engine and stop-start lights come on. The garage said it needed new battery which was replaced. Not even a day later both lights are back on. They said the alternator is fine. So what is the problem?

Marnie (Torquay )

Jul 2025 Filed under: fault

Expert answer

Hi Marnie,

It could well be that the wrong type of battery was used, so perhaps take a look at that, but there can be many other reasons causing the stop-start system to give an error. Really, it needs to be plugged into a diagnostic computer to get to the bottom of the problem. A good mechanic should be able to do that for you.


Any known issues with Honda Shuttle brake servos?

Have you heard of issues with the brake servos of Honda hybrids? I have a recently bought a Japanese import Honda Shuttle from 2020, low mileage. I am now getting intermittent faults; seems the brake servo is faulty and is not giving proper feedback to the brake pedal.

Thanks

Roy Hogan (Dublin)

Expert answer

Hi Roy,

There are documented issues with some Honda hybrid brake servos, yes, though not specifically the Shuttle that we can see. 

Many of these problems can be caused by a failing 12-volt battery, so first thing to do is have that checked or replaced. Then have the fault codes reset, drive it for a while, and if there are still issues get the car plugged into a diagnostic computer for analysis by a good mechanic.

Unfortunately, it's an expensive repair to replace the system itself, so hopefully the battery sorts it out.
