turbodiesel engines

My brother-in-law Frank – the retired professor who lives in Pittsburgh PA – with my sister visited the UK a few months ago, and was quite taken, nay surprised with my Skoda Octavia with the VAG Group 1.9 ltr turbodiesel engine.

From what I gather, Diesel has not taken-off as a car fuel in the USA in the manner that it has over in Europe; there was a time here some years ago when diesel fuel was much cheaper than petrol (gasoline) but no longer, in the UK at least the two are almost at parity.

The engine is (apparently) bombproof – the service interval is in the order of 25,000 +/- 5,000, and it sips oil exceedingly sparingly after having been run-in.

It accelerates quite linearly from 50 to 100, and is very quick off-the-mark so long as you are not scared of revving it quite close to the line; the effect of deploying such torque can quite shock drivers of hot-hatchbacks who have to change gear to keep up with your one long pull.

Some statistics from my recent trip up north according to my trip computer and/or some basic maths:

Figure Value
Total Distance 830 mi (2x 340 + 150 touring)
Average MPH 48 (return route average only)
Average MPG 59.2
Fuel 14.0 br.gal. == 63.6 ltr
Cost 64 ltr * £0.89; == £57-ish

So, there you have it. 57 quid to go from Reading to Northumberland, loop round southern Scotland, and drive back; an average of 48MPH is pretty good for motorway+urban driving, which I generally reckon to be 30MPH average on my 125cc bike, and a little under 40MPH on the Suzuki.

What amazed Frank was the MPG figure – these are British gallons which are 20% larger than American gallons (there are 20 fl.oz per Pint, in the UK, 8 pints to the Gallon), so that’s the other bit of maths:

British Metric American
1 UK Gallon 4.546 ltr 1.2 US Gallon
59.2 MPG 4.8l/100km 49.3 MPG

This is probably the point where someone will say that fuel mileage gallons are normalised around the world to some standard, but I don’t know if that’s true; the figure of 49MPG is still pretty impressive in anyone’s book, especially important when you realise the price of a US gallon bought with US money in the UK:

(£0.89/ltr) * (3.785 ltr/USgal) * ($1.86/£) = $6.27/USgal

Yep – six bucks and twenty seven cents per US gallon – and you wonder why the rest of the world laughs when you complain about filling your SUV?

ps: Yes, engine aside, my car is basically the same as the VW Jetta.

    With my 1.9TDi Skoda Fabia, I tend average over a tank (with me this is driving on all road types) 53mpg. But that’s driving quite quick and not being overly careful. Though I tend to leave the computer on instantaneous MPG reading as it encourages me to lift the throttle a bit and drive a little more carefully. If I’m a little more careful to eek out more I tend to get the figure you get. Out of interest, what sort of speed were you doing on the motorway?

    The Octavia is a golf/jetta stretched floor pan, with some shared components, though I think some of the engine tech is slightly older. I know with my car the floorpan was from the 2004 model Polo. Despite it being the 2001 model Fabia, but that’s the way the VW group seem to be going.

    I’m a big fan of teh VW turdo diesel engines. They really are a good bit of tech and are good fun to drive. Though I’d like to have a play with the Fabia vRS.

    I have to say nothing seems to wind up BMW and other similar drivers (making gross stereotypes) than being overtaken by a Skoda (particularly the Fabia), it really seems to bother people. 🙂

    what mileage has your fabia done?

    my MPG improved after hitting 30k.

    ps: speed: anything from crawl to perhaps marginally over the limit, generally cruising at/below the sort of speed for which they’d bother nicking you.

    Crap US cars & Kyoto

    There is an interesting news piece in New Scientist that posits that the US could meet its Kyoto targets purely by doubling the fuel efficiency of all its cars.

    Sadly Kyoto is probably too little too late..

    It’s done just over 50k, I think the speed travelled has a good effect, though I’ve been impressed at how useful the mpg calculator is in showing you what effecient driving is. 🙂

    OT: is that an Aussie NewScientist, or do you get it imported?

    It’s an Aussie edition of NS, with the Westminster bit replaced by a section called “Antipodes” reporting on the interaction between science and politics in Australia and NZ.

    I’ve found the thing that annoys BMW (and Merc) drivers more than being overtaken by a Skoda Fabia.

    That’s someone overtaking or keeping up with them in a 26yr old VW Derby (booted Polo). Can’t think why but they definately feel the need to prove something. 😉
