    A little high priced for 'stuff' you can do yourself. For those without any technical savvy, still high priced. It might be a decent service for 1/2 of what they are charging. Also, why are they called Europrius? Do they install rear disc brakes? Hmmm, maybe worth it after all. My two cents...

    I think this site is owned and run by a Realtor who has lost a heap of income due to the housing crash, and he's looking for a cheap way of making money out of people who don't have any technical expertise and too much spare cash.

    The web design is pretty terrible too. I always regard sites like that with caution since it generally denotes a site which has been put together in a hurry...

    i was reading something about a euro diesel that can get 60 miles per gallon using euro emissions, but the american version with its emissions, can only get 42 miles per gallon.
    i think there will be a market for people who want to hypermile thier hybrids by changing the emissions out

    (yeah i know its diesel vs gasoline prius, heh)

    It's nothing to do with emissions standards - it's the different measurement procedures.

    The Imperial gallon is 20% larger, which takes you up to 50mpg. The remaining discrepancy is explainable by the different U.S. and EU fuel economy test procedures.

    The EU test cycle starts from cold, runs four cycles of the ECE15 test (simulated urban driving), then a higher-speed test (simulated extra-urban driving). It reaches 75mph for a few seconds only - most of the extra-urban driving is done at around 50mph. The results are used directly.

    The US test discounts the dynamometer results by 10% on the 'city' part of the test, and 22% on the 'highway' part of the test. That accounts for much of the drop you see. In addition, from the 2008 model year, three new tests were added to test high speed and fast acceleration, use of air-conditioning, and cold-weather driving, all of which drive the estimates down.

    The Prius, which is virtually identical in both markets, gets a combined cycle result of 65.7mpg (Imperial) on the New European Driving Cycle. The US figure is 46mpg (US gallon). The UK specification car does not have the bladder in the fuel tank (no restriction on evaporative emissions), nor the coolant thermos, which improves 'cold-start' fuel economy slightly. Note that it easily beats Euro 5 limits already.

    In a petrol car, the engine is controlled by controlling the amount of air brought into the combustion chamber, with a throttle plate. This throttle reduces the diameter of the pipe leading to the cylinder, which reduces the amount of air brought in. It also increases the amount of force required to suck the air in, though. This causes loss of power and loss of efficiency. This 'partial power problem' is why small engines get better economy for a given power output than larger ones.

    Diesel engines control their output solely by restricting the amount of fuel injected. It's most common, in fact, to use a turbocharger to increase the air supply to the engine. They therefore don't suffer this partial power problem. However, it means that they run lean at low power, which causes greater NOx production, and the compression ignition method produces soot (particulate). For that reason, petrol engines are permitted to produce more CO than diesels, and diesels more NOx than petrols.

    EuroPrius that shows MPG instead of km/l. :)

    Europrius is a hobby of mine. I am a Real Estate Broker and luckily I didn't loose any money in the economic downturn (sorry to break someone's heart). Save when times are good, and coast through the lean times.

    I take time out of my busy schedule, and I do have a busy schedule, to help some people out. In this case, Prius owners. The price of installation was arbitrary. It pays for itself quickly, so it is a good investment for the Prius owner even at a price that seems to be twice the price that other's discuss charging. I would imagine that discussing charging less, because they don't live in the Puget Sound Area or their time is of very little value.

    For those of us who can actually handle the electrical behind the glove box, it isn't that hard of an installation. For everyone else, the amount of damage can be extensive with wires getting pulled out that were not part of the instructions, which are wrong to begin with, but can be easily modified.

    Actually, it all comes down to why you bought a Prius in the first place. You may have bought if because you like the technology. Maybe you like the gas mileage. Maybe you just like to be different. I bought mine, because I like the planet. I install EV switches, because it makes a difference, and I like people.

    Never thought my website would get discussed though. For those who don't like the way my website was designed, that's fine. There are lots of things such don't like. Just add it to your list, or throw away your very long list and enjoy life. Maybe take a long drive in a Prius. Do a little coasting, drive in stealth mode, go crazy!
