    Hi all,
    Im moving back to Ireland shortly and need to buy a new car. With diesel being on the way out i am looking at hybrids.
    I will be travelling frequently from Galway to Dublin for work and am wondering what the effecency of hybrids on the motorway for such a journey would be. 
    What cars would be most efficient for this or am I as well off in buying a 2L petrol? 
    Any advice or help is appreciated.

    Diesel won't be phased out for another while. I suggest a diesel if you're doing that distance regularly.

    On the contrary , I drove a MK II Prius for 4 years and what you loose on the motorway you gain in slower driving and in town.

    The way to think of it is what's the average per tank of petrol not per occasional trip.

    With commuting my average was 4.4 Summer and 4.6 that's about 60-64 imp mpg, Winter per tank of petrol, single trips are irrelevant really because it's what it cost per tank is what matters. Driving it hard I could not get below 5.5 L/100 km or 51 imperial Mpg. ( not U.S)

    My advice is to drive one and see for yourself, get a test drive for a day. guaranteed you'll love the petrol auto over the manual soot box and even if it costs a bit more to run which i doubt than a diesel then it would be worth it in my opinion.

    The likes of the prius is one of the most reliable cars ever made and will not need any high maintenance compared to a diesel, no belts to replace ( all prius after 2010 ) only oil, filter and spark plugs and brake fluid for the life of the car, coolant change being the major service on a Prius after about 160,000 Kms lol.

    The MK II prius only had a belt to drive the water pumps. All models after have no belts.

    The prius has moved on since 2007 or rather 2004 when the MK II was released and they're much nicer to drive today.

    Other options today are the 40 Kwh Gen II all electric Nissan Leaf and BMW I3 33 Kwh Rex which offers about 150-180 Kms all ev range with the backup of a small petrol generator.

    Hyundai ioniq EV being another.

    basically you should only need to top up at a charger for very little time or not if you drive a bit slower, the i3 Rex would mean no stopping if you do not want to or top up at a fast charger if you want to save fuel but it's got the potential to save you the most money on fuel if you want long rang EV with backup.

    It is more expensive, 2nd hand about 35K but a Prius new would not be a lot cheaper but it's larger.


  • Posts: 21,179 ✭✭✭✭ [Deleted User]


    I got from Joe duffy motors in Fingals to the KFC in Galway at Briarhill before the Rex kicked in driving at 110 kph most of the way, that was good going the battery only version can travel maybe 10-15 Kms more on electric , worst case you might need 5-10 mins top up on route in colder wet weather but in the Rex you don't have to worry about it.

    Anyway I recommend that you take this drive in the 40 Kwh leaf, Hyundai Ioniq and a BMW I3 33 Kwh Rex and the Hybrid.

    When do you want to buy and what is your budget? Hyundai Kona EV will be in the showroom in a few months time and it can almost do Dublin to Galway and back without charging. For about EUR 4 in electricity.

  • Posts: 21,179 ✭✭✭✭ [Deleted User]


    True, never thought of that..... 60 Kwh. But how available will it be I wonder ?


  • Posts: 21,179 ✭✭✭✭ [Deleted User]


    If you're to get 22 Kwh/100 km at 120 Kph could be more but lets say 22 then that would get you 4.24 kw per Km or roughly about 250 kms with 55 kwh of usable storage estimated with 60 Kwh.

    So not exactly there and back. But will depend on efficiency it's not going to be as good as the Ioniq.

    I seriously doubt this car would get much more then 50 Kms more than the Ioniq at 120 kph ? thoughts welcome lol.

    Again this doesn't take into account slower driving off the Motorway.

    Ok a few questions
    How often is frequent? weekly? monthly?
    Apart from trip to Dublin what will general day to day mileage be?
    What size of car you looking at?
    Do you have kids?
    Will car be your primary car?
    Budget of course?

    No you dont have to answer any of the above but it might be helpful.


  • Registered Users, Registered Users 2 Posts: 8,295 ✭✭✭n97 mini


    I drive a 2004 Civic IMA. Did Dublin-Cork-Limerick-Dublin during the week at motorway speeds (where applicable). Such a shame Honda don't sell a hybrid here any more and have jumped on the diesel bandwagon.

    Dublin to Galway and back on 1 charge in the Kona at motorway speeds.

    To get to Dublin and back with about 55 Kwh usable you'd need an efficiency of 13 Kwh/100 kms. No chance at motorway speeds.


  • Registered Users, Registered Users 2 Posts: 5,708 ✭✭✭Charlie-Bravo


    I'd say you'll average 45-50mpg on motorway driving with an Auris Hybrid or Prius. If you want better value, diesel would be the way to go with cheaper price per litre, and an average of 50mpg or so (say for the likes of a 1.6 litre diesel Avensis). You might have higher servicing costs with the diesels so do your homework.

    If you're eco-friendly, definitely lean towards electric cars with good range but charging may be the issue at the other end (depending on your exact destination). I own two hybrids and I can't bare the thought of going back to diesel. I'd love to go to electric but they're isn't enough infrastructure yet for my needs!

  • Registered Users, Registered Users 2 Posts: 2,318 ✭✭✭Miscreant


    I do the Dublin to Galway run once a month in an Auris hybrid and get 54mpg. I usually set the cruise control to 110kph and just let it run all the way there and back at that speed. I have never done the trip in a diesel so I can't speak for their economy or for an EV.
    I'm tempted by the thought of a 60kw Kona as I could drive to Galway in one shot on the motorway and then charge up overnight for the drive back but that is some time away for me budget wise.
    If you're looking for something that will make the journey without stopping in either direction then I would definitely recommend the hybrid.

    I said it would almost make it. And it has 64kWh usable. Hyundai don't cheat ;)

    An Ioniq with 64kWh would make it there and back at a push. In Kona, at motorway speeds, you'd need one 15 minute charge. Only Teslas can do this so far, a budget EV able to do this is a major breakthrough imho

    Almost ?

    Ok so if it's got 64 Kwh usable and it gets 22 Kwh/100 kms on the motorway then it would get 290 kms but that's to stopping.

    Hmm still a wee bit off a return trip don't ye think ? ;)

    It would need an extra 30 Kwh to make a return trip and a bit more for comfort.

    Recharging , what's the charge rate again 100 Kw ? Hyundai quote 54 mins to 80% so it's not 100 Kw ore like 70 ?

    I wonder am I being too generous with 22 kwh/100 kms. But good range and at slower speeds would be pretty good indeed.

    Its 64kWh useable

    Agree not a chance without a 10min charge

    Ioniq takes about 16kWh/100km at motorway speed so would make it, Niro is speculated to use 19.5kWh/100km, pretty close too

    Kona from reading will be pretty terrible at motorway speeds, 40% less efficient than Ioniq @ 22kWh/100km

    Ioniq hopefully will get the battery down the road too

    2018 Kona has 470km WLTP range. To put things into perspective, that's double the WLTP range of 2018 Leaf which costs nearly as much (early €30k ish)
    The only other cars with that kind of range are Teslas (over €90k)

    Dunno why you're being so dismissive, Mad_Lad. Kona will go down in history as the first budget EV that can do long distances.


  • Posts: 21,179 ✭✭✭✭ [Deleted User]


    I'm afraid the Ioniq with 64 Kwh would "almost" make it as Unkel would say lol if it achieved 16 Kwh/100 kms excluding crap weather. But I'm betting 22 Kwh/100 km would be a better bet. Still it allows a lot more freedom from fast chargers especially if it can charge quickly enough.

    Once electrics cars become more practical they'll inevitably loose efficiency as people with families opt for space over sheer range.

    A Ford Galaxy for instance might only get 25 or more Kwh/100 km.

    Where was I being dismissive ?

    So WLTP is just as deceptive as NEDC ?

    I gave 22 Kwh/100 km as an estimate at 120 Km/h.

    470 kms would require 13.5 Kwh/100 kms and hardly reflects a Dublin to Galway motorway stint.

    And we're not talking Leaf , don't even get me started on that lol we're talking Kona and I'm trying to give a estimate of driving at 120 Kmh , obviously to at 13.5 Kwh/100 km efficiency isn't going to be very practical on the motorway and it's not going to be as efficient as the ioniq.

    Not sure what you are on about here? Ioniq with a 64kWh battery would be able to do a Dublin to Limerick run and back without charging in good circumstances.

    Are you ridiculing my statement? If not, what's the point you are trying to make? To be honest, your posts seem to be all over the shop in the last few days.


  • Posts: 21,179 ✭✭✭✭ [Deleted User]


    OK lets put it another way.

    An ev with 64 Kwh would need an average of 15 Kwh/100 km efficiency with 64 Kwh to make Dublin to Galway return trip. At 120 Km/h could a 64 Kwh Ioniq do that comfortable in all conditions ?

    Yeah sure if it charged at 100 Kw and connected to an Ionity charger it would need at the very most a short time on a charger but so would most electrics at that rate.

    22 Kwh was a guess of the Kona because it's not going to get as good efficiency as the Ioniq , no hope and I'll drink petrol from my i3 tank if proven wrong !


  • Closed Accounts Posts: 18,958 ✭✭✭✭Shefwedfan


    Lets put it this way, if you are going from Dublin - Galway - Dublin at some stage you are going to stop. It just means you need to consider a top up.

    Dont get me wrong, I think the Kona will be able to do it but you might need to restrict speed and comforts.

    So throw a few kW's into it at some of your stops off's and away you go.

    The answer to every question is not to strap a petrol engine onto a car Mad_lad :-)

    I have eGolf and I knew exactly what I was buying so I hardly ever use the charge points in anger(twice in a year). So once you know what you are letting yourself in for then no issue.

    I have saved over €1400 this year in fuel doing 15k km so if OP is looking to move to electric you do get huge savings.

    I would suggest looking at the Kona thread as well before holding on.....

    Since you got that 700cc petrol your really negative about EV's

    A year ago you would have been delighted with a Kona in 2018

    300km motorway

    400km mixed driving

    I was very negative on EV's but even I can see that's a game changer, it's perfect for 99% population

    I can't believe it's out so soon

    Motorway drivers that do over 300km a day are probably better off waiting a bit for a more efficient motorway mile cruncher like a Model 3

    They are a tiny % of the population and would drive big diesel BMW or VW anyway, which Tesla are an alternative for

    Speed V charging, that's what it comes down to. Personally it's of no issue to me. 64 Kwh is a lot more juice in the tanks than a 24 Kwh Leaf. :D

    It's necessary for now until the range and charging network greatly improve, as I said before it's already proved it's worth, passing queues at charge points is just fantastic. it's got decent ev range for most of my driving and a backup when I need/want it, perfect until perhaps my next EV, it didn't work out that I'd have a 60 Kwh EV with faster charging by the time I had to say goodbye to the Leaf.

    Coming back to the OP's topic about a prius/hybrid

    We have a mark2 prius 2008. Doing a 75% motorway commute at 105-110km/h it does in the low to mid 50's MPG. More if I'm driving as I hypermile the 25% non motorway bit. I can hear Mad Lad in my head..."pulse and glide... pulse and glide"


  • Closed Accounts Posts: 18,958 ✭✭✭✭Shefwedfan



    ??

    The kona is not available so the buyer would need to wait to get.....no point waiting if the car wont suit in long termh


  • Posts: 21,179 ✭✭✭✭ [Deleted User]


    The OP hasn't come back to say how frequent the trips from Dublin to Galway would be.

    The newer generation Prius is more efficient again.

    Is the OP considering New, 2nd hand, what's the budget ?

    If considering new I'd definitely hold out to see what the Kona 64 Kwh is like without doubt the cheapest way to drive that trip is EV and having 64 Kwh would be really great and would mean only a few mins , on the return trip maybe 20-30 mins max is all you would need on such a trip.

    If and it's just a guess but if the Kona averages 22 Kwh/100 km at 120 Km/h then 30 Kwh would be needed to comfortably make the return trip but that doesn't include driving around Galway etc.

    Here's the great part, if the OP can find a public AC point then 9 hrs on a public AC point would bring the Kona from empty to full again meaning a fast charge on the way back might not be necessary at all.

    IF the OP wants hybrid then the I3 Rex offers no compromises , it can make the trip all the way without charging but it's recommended to keep the battery topped up but it will still offer 150-180 Kms EV range + unlimited on petrol, you'd have to stop to fill up which should give about 100 km range and that takes 1 min to fill up or a bit less. 8 litres.

    The i3 also looks to be roomier inside.

    The Kona 64 Kwh with a charge in Galway on AC would guarantee a return trip without having to stop on the Motorway for a charge + a wait if someone is already charging, the i3 offers no waiting in this case, just fill up with petrol and drive off.

    I've not tested the i3 at motorway speeds with a depleted battery but at 110 Km/h it will not suffer any power loss at 120 Km/h I've not experienced power loss either.

    With the Rex the idea is to turn it on as soon as it allows , at 75% battery to preserve as much battery as possible, then you can get to Galway plug into AC fill up the tank and drive back home. AC charge empty to full should take 2.5 hrs on ac with a 3 phase Charge lead which should be really convenient.

    No not available yet but the OP could buy a really cheap car drive it for a while and might be able to use it if a scrappage is offered, might get a few K off the cost of the Kona.

    We don't yet know what the OP's views on all this is and no signs of Him/Her getting back to the conversation lol.

    I wouldn't count on a Hyundai scrappage deal on the Kona, they've learnt there lesson after Unkel practically stole an Ioniq. Then again my deal wasn't much worse.

    Traded in a 2k car, dealer reckoned he could sell ours after the first year for 4k more than we bought it.

    All the Hyundai dealers will know they can sell every EV they can get, so I doubt there's any discount off the full list price. Why would they give a discount if the cars will sell without a discount? :)

    I've never gotten below 50 MPG with my 2012 Prius and motorway driving, so I'd say you're wrong :) . And that's driving with cruise control set to 120 km/h (130 km/h indicated), no "hypermiling"nonsense. I have the plug-in version (larger battery) but it makes no difference at those speeds (if anything, it's heavier). I'd also say a 1.6 diesel Avensis is gutless and unrefined in comparison.

    For the OP's comparison to a 2.0 petrol: You'd be hard pushed finding one in this country (outside of sportier models), and they will be much worse on fuel than an equivalent petrol hybrid.

    The 4th generation Prius (2016-) is even more efficient, and will do around 60 MPG at these speeds. The current Auris is still using the 3rd gen Prius drivetrain (so will be more like 50-55 MPG), but the new one will be out very soon.

    So it really depends on the OP's budget.

    If they're buying a new car, or a current gen Prius: A hybrid will match diesels for fuel efficiency
    If they're buying something older: Unless you're doing >70% motorway driving, they may still do better overall than a diesel, and there's still something to be said for reliability and total cost of ownership (lower maintenance costs + Toyota hybrids hold their value).

    People talk a lot about experience with the 2nd gen Prius (2003-2009) which does not reflect the improvements that have been made with the technology in the past 15 years.

    Not in all conditions. I said in good circumstances. I drove to Waterford last summer mostly at 120km/h and did the 170km with roughly 10% left (I slowed down to 100km/h for the last maybe 40km iirc but I drove in sport mode, with active cruise on and no hypermiling techniques whatsover)

    That's 14.5kWh/100km. So the 400km Dublin to Galway return would use 58kWh.

    In Kona at about 100-110km/h you should be able to drive to Galway and back without charging. And that's a game changer that a budget EV can do that. That's my point.

    A few people on the eGolf forum have said similar....

    One person had bought last year, was waiting for delivery, car arrived...went into dealer and they changed the whole deal, more or less told them to take it or leave it, they didnt care as they could sell the car anyway.....

    In Kona at about 100-110km/h you should be able to drive to Galway and back without charging. And that's a game changer that a budget EV can do that. That's my point.

    Lets calculate that again, my maths might have been out a bit.

    410 Km return trip , 15 Kwh/100 kms efficiency = 6.66 Km per Kwh = 426 kms.

    That's 426 Kms to empty, the question is at what speed can that be done at which will be really interesting, can't wait to try one out myself.

    100 Kw charging would be sweet , of course we need the chargers first.

    Even plugging into AC point at 7 Kw will give around 6.6 Kwh per hour and that can't be sniffed at either. It would reduce the time needed at DC points.

    Either way I reckon most people won't drive at a speed that means a return trip on one charge but don't dismiss this as me being negative , most people will have stopped anyway either in galway to do business or stay the night which they maybe able to find an AC point which will give them plenty of range the next day possible without having to stop at all or need less time on DC either way it's a big step up from a 22 Kwh EV.

    Lets calculate that again, my maths might have been out a bit.

    410 Km return trip , 15 Kwh/100 kms efficiency = 6.66 Km per Kwh = 426 kms.

    That's 426 Kms to empty, the question is at what speed can that be done at which will be really interesting, can't wait to try one out myself.

    If they include 22kw AC it's just heaven

    I haven't looked at the exact figure for consumption here but my experience in a late 2016 Prius is that one tank of fuel (€43 ish depending on price) will comfortably take me from Cork to Dublin and back again and have enough fuel to drive around Dublin while I'm there for a couple of days (short drives to offices Etc).

    I honestly can't say that I find the current Prius models inefficient on motorway driving.

    The main things to watch (And this applies to any car really by no means unique to the Prius)

    1. Use cruise control. Set your speed at 120 and avoid sharp acceleration and braking. You should be aiming to do most of the journey without ever really adjusting speed unless you absolutely have to. You waste a lot of fuel by driving by overtaking late, getting caught behind slow moving vehicles and then accelerating hard to do get back to speed again. Drive smoothly and at the speed limit and you really notice the fuel efficiencies improve.

    The hybrid system doesn't actually exclusively use the engine all the time at cruise speeds and it will make use of the power its picking up on downward inclines and use it later on upward inclines. Irish motorways aren't totally flat. It's not the Netherlands.

    2. Air conditioning - set it to a sane temperature and to automatic. It burns a lot more fuel than you'd think if you're picking very high or low temps or if you're running it exclusively on no recirculation. In auto mode the system works efficiently and gives you a pleasant cabin air change. You can otherwise be dehumidifying and heating or cooling vast amounts of air unnecessarily. Turning the AC off entirely isn't really necessary either - just make good use of the climate control settings and don't spend your trip blowing air conditioned air out the vents into the countryside, which is what you do when you put it into totally manual mode without recirculation.

    In general the Prius air-conditioning and heating is very well designed and efficient. My only complaint is that it's poor at heating the car initially on a cold day until you get moving. Preheating the car in the driveway isn't always that effective at clearing windows takes 10min + but then once the car moves it seems to rapidly kick in. Odd as it wasn't quite like that in older Priuses which had pretty high impact AC when turned on, when when started cold.

    3. Use long, gentle slows downs as you get into traffic. Start by using the "B" option to add gentle drag rather than braking repeatedly. Gently braking also generally only causes regenerative braking. You're wasting power by excessively using the disc brakes as that's just converting that potential energy to heat and losing it into the environment instead of the battery.

    Drive at the speed of the traffic and maintain a safe distance. Constantly catching up with the queue and closing the gap and changing speed is very inefficient.

    Basically : smooth, smooth and smooth!

    Also the Prius typically has very very detailed information on your hybrid system and it an help to adjust your driving style to read it. The info on other hybrids including the C-HR models I've experienced is a definitely less detailed and they use more traditional displays. You still get some info but not like the deep detail of the Prius.

    Absolutely, I had forgot about that. That means a full charge or at least 90-95% in 3 hrs.

    So you get to Galway, and lets just say for arguments sake you do get 22 Kwh/100 kms at 120 Kph, you'll get to Galway with some to spare , you plug in at 22 kw AC point ( some are still 3 Kw ) and get to 95% in about 3 hrs then you don't have to fast charge on the way home.


    Or..... you get to Galway, stay a night, full charge , take a road trip around Galway, get to another town, plug in over night and full charge all the time avoiding fast chargers.

    Some hotels even have 3.7 Kw AC points. Perfect for over night.

    CHR has all the same screens as the gen 4 prius in the entertainment and navigation screens. Off the top of my head the only thing you lose is the "score sheet" that the prius can show you for driving style.

    It could just be the optionalfeature set I saw on both but the dashboard display on the Prius provides a lot more info. It's not all on the touch screen.

    The CH-R dash display was just dials.
