relocating to Austria

Just because the car is a European brand does not mean that it has the same specs as the European version - all kinds of parts may be significantly different. This may not be a problem for a short term situation, but it is well worth your time to investigate this.

Sell the car. Shipping a car across the ocean is not cheap. And once it gets to Europe, there are as mentioned a lot of different legal requirements and it might take a lot of work to actually be able to register the car in Austria.

I agree sell the car. You'll probably need new chargers for the ebikes too. With modifications to the car if legal, It may require a new VIN number. I looked into this for a US Audi A3 I owned at the time retiring in Germany after government service. There are waivers for US Government personnel to have US Spec autos in Germany. Audi strongly recommended no conversion from US Spec to German Spec. I think you need a bonded carrier to ship a US car to Europe too. It's been some time since I looked into this and I do not know Austrian specific, but a think buying a used car in Austria is the better way to go. Your US car navigation system etc. may not function correctly either. There might be insurance issues too and eventually you will probably need an Austrian drivers licensee?

Like others have said, importing a car from the USA is not cheap. Plus probably more significant is whether it’s worth your time hassle, and also since you’ll be in Vienna, have you considered that it is possible you may use your car less or even not at all? In other words, how you move on the ground could be different from how you did it when you are in your own homeland.

But of course, perhaps you’ve considered all of this and you’re still finding importing your car worth it. In that case, I’ll say that I did a quick Google search and the Austrian government website has very clear directions on what needs to happen, and there are some older posts on other websites that talk about the hassle of importing a non-EU car vs. car from another EU country.

As for the ebikes, I don’t think difference in electricity voltage is a problem. Ebikes use DC batteries so change in voltage is not a problem. It just means your charger would need to change, not the battery. Or, it could be that your charger is already multi-voltage which it very well could be.

Another thought too, to tack on to the first post that responded:

When your car needs part replacement, does it become more difficult to get the necessary part from your local Austrian mechanic because your car is a US-spec model versus one spec for EU market? Consider that and investigate. Importing the car is one thing. Then, think about LIVING with one on the ground in a location that the car was not spec to be. Maybe the differences don’t matter enough; I don’t know. But, it’s worth exploring to see if getting maintenance causes more hassle than it’s worth.

It is highly unlikely that your car meets the emissions requirements for Austria. You would likely need to spend $$$$ to modify your car. Just sell it. Chances are you won't even need a car. I've lived here for 16 years without one and never missed it.

I agree with the others in that it's probably going to be costly to transport the car to Europe, and then modify it to meet European specifications. I assume you'll be returning the U.S. at some point in the future? If you have a relative with a large driveway or spare garage bay, perhaps you could store the car there? Get storage insurance and cover it with a car cover, and it should be fine for a few years. If you know a good mechanic, ask them about long term vehicle storage. This website provides some tips - https://www.carfax.ca/resource-centre/articles/how-to-prepare-a-car-for-long-term-storage .

The E-Bikes should be fairly easy to transport, and perhaps something like this would be an option - https://www.shiptocycle.com/shipping-usa-canada/from-or-to-usa . Have a look at the chargers to determine the Input Voltage specifications. You may only need a Plug Adapter to operate them in Europe?

Have you consulted with your new employer about any of the details you need to manage to move there for your new job? No matter who they are, I'd think they'd help you with all that. Other posters have touched on some potentially relevant issues beyond your vehicular concerns.

It was in the last century, my employer was the US Army and my initial commitment was for 3 years, but when I moved to Germany there were many tasks to be done both prior to and after my arrival in-country. I'd expect that would still be the case for Austria these days and that your employer knows what needs to be done and how to do it.

I'd expect things to go faster now, but back then my VW Rabbit was shipped from WA to Germany. It arrived about a month or so after I was already there and working. I took a train to the port and drove it back to Nuremberg.

My household goods took even longer, so I couldn't really move into an apartment until they came. That wasn't a big deal because housing was very tight and I stayed at a friend's place and took care of her cats while she was on leave for a few weeks in the US.

Note that almost all the arrangements and expenses for my move and housing were covered by the US Government. I mention my experience as a hint of just a few of the kinds of details that you'll likely need to manage. Your situation may be entirely different, but I hope you'll sort things out and have a great experience working in Vienna.
