Prius and Fuel Economy

    Despite the negatives in several posts on this foum I went ahead and bought a new Prius Gen 3 a few weeks ago. Took it to France where I did 1200miles of mixed motoring - cities, towns, country roads, motorways. Petrol consumption over the entire trip was 4.6litres/100kms which works out at about 61mpg which I thought was pretty impressive. This included about 700 miles of motorway at the maximum allowed 80mph. Very comfortable . Normally I have back ache after about two hours - with the lumbar support on the Prius I found I could drive for more than twice that time without any problems. The car was well powered even without using the Power function which switches it over exclusively to its 1.8l petrol engine - in fact I didn't use the power function at all and had no problems overtaking. Driving was all in western France though which is fairly level; mountainous areas might be different. Passengers, one front one back, found it comfortable too. Boot took plenty of luggage. Overall I was impressed.

    To be fair it probably deserves its own thread. There is too much knocking of the Prius by most people who are petrol heads but hybrids and renewable sources of energy are the way forward.

    I actually saw a Tesla in County Cork today.

    Anyway, the new shape Prius is quite nice to look at. Big alloys and a nice bit of kit on it as standard.

    how about Hybrid and electric thread ?

    The hybrid thread will do just fine. Until the ESB can actually provide a proper network of couplings then its all simply pillow talk and nobody will be encouraged to get a "lecy" car unless they are the "save the cheerleader, save the world" types.

    in reverse order.......

    ..nothing wrong with the look of the current Prius, I'll give you that.

    ...yes, there is knocking of the Prius more as a result of the fact that, economically, it's poor value. Paying a lot extra for a vehicle, to only match that of conventional technology (a small diesel), is well, false economy. Depreciation alone sees to that. However, if you just plain like the car, as a car, then, of course, you should buy it. I'm one (of many) who buy other, and as-often-equally-derided car choices, but hey, that doesn't stop me, either ! :D

    And I don't think Hybrid is the way forward, actually. At best it's an interim technology, until something better comes along - remember, there is nothing renewable, energy-wise, in a hybrid at all. Even the regenerative braking is there by dint of the kinetic energy imparted by........the fossil fuel it took to get it to it's terminal velocity in the first place !

    You know, even that won't do it. I'm writing this from Atlanta, where I've been for the last week, and I have to tell you, we at home are idiots for following this green philosophy to the extent we do, when, especially around here, no-one else is in the slightest bothered.

    As of today, petrol is at an all-time high in this area, of Euor 0.66 per litre. That's right - approx one-half of what we're paying.

    The current generation of cars, whilst being naturally more efficient, by dint of being new, are being sold on the basis of power, torque, acceleration, mass, even. Even a new Panamera in the showroom yesterday (at less than half the Irish price, btw.......:rolleyes: ), carries an EPA rating which rates it 50% better than the 'average sedan' car in the US, because it is efficient, not targetted on a specific mpg.

    Likewise the Dodge dealership down the road: new Challenger (fab, btw), available in either 3.5L V6 (basic), 5.2L (iirc) popular spec, or 6.2L (iirc) top spec. Mpg is not a factor in buying these cars, not because they don't care, or because it's irrelevant, but because they want the cars, and they are reasonably priced, and, well, people don't like being 'told' what they 'have' to drive. Works for me, as they say.

    Even my Mam's old car I've been driving all week, an 02 V8 Mercury, has only used US$39 worth of juice in 5 days of every-day use.

    If you are a Prius fan, you should watch "The Other Guys". It is the cop car in it. Some choice quotes too.


  • Registered Users, Registered Users 2 Posts: 26,158 ✭✭✭✭Berty


    galwaytt. The MPG is not a factor in the US because you could argue they invade countries and steal their oil. :D But thats a story for another day.

    If they were paying, 1.30c per litre and they will be eventually they wont be interested in big GAS guzzling big engined cars.

    Don't get me wrong I would love a big V8 and to hell with the world itself but I cannot afford to tax or fill the tank in this country. If I was living in the US I would have a massive engined car.

    However in this country we are all playing along to the green agenda because we have no choice unless you are loaded.

    When you refer to the Hybrid technology and only being here in the interim and not the way forward: Yeah I agree with that. Hydrogen fuel cell technology like what Honda have is probably a good idea if we can only put it out on masse. We cannot get the lecy right in this country, let alone anything else.

    Heck Bioethanol stations are few and far between.

    Sometimes you just have to "give up" with the green agenda and start sucking down regular diesel and expensive petrol instead.

    I suppose in some ways all technologies are "interim". But that doesn't mean that we shouldn't use them until the something better comes along - if they work. I agree that the hybrid may not be the way forward and it is certainly not a "renewable". But I don't think anyone makes that claim. The key thing is does is save on fuel? And in my experience it does. I can't think of any other family, saloon car with a 1.8l engine that will deliver 61mpg over 1200 miles with three adults and a boot load of luggage. Modern diesel engines are great but most of the fuel stats I see for them are manufacturers' claims, not the results of actual driving under varied conditions.

    This is true for the moment (though plug-in hybrids are on the way). That's not to say that hybrid (or hybrid-esque: see the chevy volt) cars don't have an important role. Sure, it's an 'interim' technology, but all technology is.

    Bear in mind that conventional car engines are at best about 20% efficient. That is, 20% of the fuel's calorific value actually ends up doing useful work. Electric tech has the potential to improve this figure significantly (and deliver perfect torque curves in the process ;))

    That's 97bhp and 72mpg on paper (less in your case because of the extra weight). Lets see...
    • Octavia/Golf 1.6tdi: 103bhp and 62mpg
    • 316d 2L: 114bhp and 62mpg
    • Focus 1.6tdci: 110bhp and 62mpg
    • i30 1.6crdi: 113bhp and 62mpg
    • Toyota, Honda, Citroen, Fiat, Peugeot are all at about 55mpg for that kind of power output

    Nope, I can't find a rival in the same size category that can manage 70mpg. That being said, I'd much rather a 2.0tdi with 150-170bhp and 55mpg, but each to his own I suppose.

    97bhp plus 142 torques then the motor throws out an additional 79 bhp plus 207 torques so potential 176 Bhp and 349nm engine and motor combined. Go drive one before you slag it.
    Factor in Automatic aswell and figures are even more in Prius favour.


  • Registered Users, Registered Users 2 Posts: 1,704 ✭✭✭Mr.David


    Interesting thread.

    How did you measure the economy though - pen and paper or trip computer? If it was straight off the trip I would take 10% off it to get the real figure, they are always over optimistic.

    In terms of other vehicles as with same economy and size etc I give you the BMW 320d efficient dynamics:

    http://www.whatcar.com/car-reviews/bmw/3-series-saloon/320d-efficientdynamics-4dr/summary/58414

    0-100km/h 8.0secs
    top speed 142mph
    163bhp & 380Nm
    69mpg combined and 78.5mpg extra urban.


    Not knocking the Prius just saying that there are alternatives.

    Well when you consider how dirty zinc mining is and how much pollution the creation and disposal of batteries for the prius causes, then you have to wonder how environmentally friendly you really are.

    When you think about it all, we (the human race not just boards motors members :p) will use up all of the oil available to us.

    Thats a given. The only question is when. How long can we make it last.

    So if we are going to use it all up anyway, then all that CO2 is going to be produced regardless.

    So saddle up, get yourself a V8 and enjoy ;)

    While you still can.

    Hi OP,

    can you describe the noise level in the cabin at motorway speeds.

    I am interested in a Prius, but a pet hate of mine is loud cabin noise at motorway speeds.

    Thanks.


  • Closed Accounts Posts: 8,704 ✭✭✭squod


    Volvo S40 1.6D DRIVe
    The fuel economy's very impressive too, with this car achieving 70.6mpg on the combined cycle and getting on for 75mpg at motorway speeds

    http://uk.cars.yahoo.com/car-reviews/car-and-driving/volvo-s40-1.6d-drive-1006226.html

    Also I'd bear in mid the standard focus 1.6TDCI has done 86mpg last year on a tested run to Wexford and back.

    Indeed! And the point I find most interesting here is that the known reserve of oil / gas is now much higher than it was when the doom sayers started shouting 40 years ago. According to them we would have run out several decades ago :D

    ...had the 5l V8 running in the driveway for about half an hour earlier just to enjoy the sound :pac:

    I guess these are the manufacturer's stats for the BMW? Impressive, and who wouldn't want a BMW, but at €32000 + its a bit on the pricey side. The 4.6l/100kms (61mpg) was a trip figure for the round journey of 1200miles but I kept a pen and paper record for the first part of the journey which gave almost exactly the same result as the trip. I have done a few hundred miles since I came back and the read out is 4.7l/100kms or just over 60mpg.

    I did about 700 miles on French motorways where the max limit is 130kph and I was at the limit for most of the time. To be honest cabin noise was not an issue; it simply didn't arise.

    List price has no direct bearing on how much the car will cost you to own it. I wouldn't be surprised if a 320d would not cost an awful lot more per month to own than a Prius. And like you say, the owner of the former would have a helluva lot more car for his money

    And (not aimed at you, Aeneas!) I wish that people who claim to care about our environment stopped buying new cars (any idea in the pollution involved in manufacturing and shipping a car and its parts from one end of the world to the other :eek:) with heavy toxic batteries. It is much greener to keep your relatively modern car for another year or two or ten...

    id rather pay 3200 more for a BMW than a prius. at least then i wont have to tint the windows and be sniggerd at by people in v8's. i mean 163bhp is well worth 3200.

    :eek: Thats serious mileage. Was this a test you did?

    Re; the prius and its eco friendliness. The mining of metals and their resulting release of CO2's etc. is hard to argue with.
    (nuclear also falls within this, lest we forget!)
    Modern diesels do very well on the mpg front but have this small issue with soot,CO, CO2, and NOx. This being a lot higher than petrol cars.
    There is currently a bit of an effort being made to sort this out but i feel it's a waste of time. My reason for saying this?
    The EGR valve.
    This was introduced to lower NOx. It does that by about 50% from what i can gather. Thats fine, but it apparently increases soot, CO, CO2 by an amount that i have yet to find out, but increases it nonetheless. By all means correct me if i'm wrong but with data please. Mileage also suffers but not by much. Engine oil also becomes acidic and the intake fills up with tar, as i have noticed first hand.
    The manufacturers have come out with these DPF's that filter out the soot caused by the egr system and use fuel to lower the burning temp of the soot, thereby causing it to burn off AND increase fuel consumption into the bargain. It's like a patch on a patch. Ridiculous.
    Apparently there is a section of society that use EGR blanking kits to increase power etc. They say their oil remains cleaner for longer too and there is no soot coming out of their exhausts.
    Are they lying? Is there a conspiracy?
    From what i have gathered, the rev heads by and large love their cars so i would tend to believe this nugget of information. Again, correct me if i'm wrong.
    So this emissions reduction malarkey is a bit more complicated than we would be led to believe. Diesels arguably cost less to run but thats due to taxes and their emissions are in question.
    Petrol cars can cost more to run but thats partly due to taxes. As has been said above, the US are driving their cars very cheaply. The reasons for this are plentiful and taboo to a certain extent.

    So, unfortunately yet again there is a balance of sorts going on here. Some will go diesel, some petrol. Its a bit like the french/jap thing going on. Jap cars are ultra reliable but for some reason some people keep buying unreliable cars.
    They are fun to drive apparently, when they aren't getting major surgery done. I've been there and it cost me a lot in time and money. Never again.
    How does this happen? Well, the balance is kept level and enough people keep buying on both sides. If it weren't for this, there would be a few manufacturers going out of business overnight.

    I suppose there is an overall point to this petrol/diesel argument. For the people that dont care, well, good luck to them if they can afford to run their car.
    But for the people that do worry about emissions or cost of ownership, well there are unfortunately a lot of arguments going for each side.

    Personally i'll stick with my small diesel that goes as fast as anyone else legally on the road, has not broken down at all, ever, AND does almost 800 miles to the (42L) tank.

    Re focus Diesel economy is it personal experience ...eh no



    Why are people so anxious to jump on the anti Prius bandwagon when they haven't even tried one.


    On another note Modern Diesels are effectively much more complicated than a Toyota Hybrid with all the Diesel electronics, Super high pressure pumps, electronic injectors,turbochargers, egr valves, complicated electronically controlled inlet manifolds,fly by wire accelerator actuation etc etc.
    I have personal experience of modern Passats, Audis, and four and six cylinder BMWs needing very expensive repairs that cost so much to effectively negate any savings made on fuel unless they were covered under manufacturers warranty.

    Petrol Hybrids are easily doing 300000 plus miles without any major issues including no BATTERY problems as predicted by all the opposition. Also brake pads and consequently Discs are lasting crazy high mileages because of brake energy regeneration. Check out pruischat.com to see the 200k and 300k miles + users
