Qt in World’s Fastest Electric Car

Digia has supported Metropolia University of Applied Sciences in their electric car project called Electric Raceabout (E-RA). This cool research project has produced a street legal electric sports car, which not only has the World record on ice, but also runs Qt.

Metropolia University, located in Helsinki, Finland, does extensive research on electric vehicles, one example being E-RA – an electric sports car built primarily by automotive engineering students.

With 4-wheel drive and well designed handling E-RA is a really capable sports car with impressive specs:

  • Top speed of over 260 km/h
  • Motor power of 282 kW
  • Peak torque of 800 Nm – in each wheel

And all this provided by an electric vehicle that is fully street legal (and rest assured, the Finnish road inspection is surely one of the toughest in the world to pass).

E-RA has achieved lap time of 8 minutes 42,72 seconds at Nürburgring Nordschleife, which was electric vehicle track record for quite a while, as well as World record as the fastest electric vehicle on ice with average speed of 252,09 km/h. Nicely driven E-RA has operating range of over 200 kilometers.

The students have built both the IVI system and the instrument cluster with Qt 4.8 running on top of Linux. I think the whole E-RA project is a really great proof of the skills the soon-to-graduate engineers have, and certainly the Qt parts are no less impressive.

Have a look on the enclosed video produced by the students at Metropolia University to hear the full story:

MartinUI says:

Great to hear that we finally have first automotive Qt application in real car (and wow! not just any car). Im currently working on my personal dashboard project which will be a combination of ergonomic and Style (yes by the big S ;):


Unfortunately I’m stuck with a problem. Could anyone tell me WHEN Qt3D return to Qt5 ? I would like to use many 3d effects in running presentation but at the moment the only tool that allows me to do that is Nvidia UI Composer, which in my in my experience terrible in terms fo implementation.

Tuukka Turunen Tuukka Turunen says:

@MartinUI: The current goal is to have Qt3D included with Qt 5.2. Naturally 3D UIs can be done with Qt without Qt3D module, but the helpers it brings are certainly beneficial.

MartinUI says:

Thank you for your reply. In that case I will wait for Qt5.2. I know that even now it is possible to create simple geometry in Qt. But I would like to import my own 3d models ( https://dl.dropboxusercontent.com/u/1331672/r1.png ) with bitmaps, 3-point light scene setup, etc… and in QML it is much much easier. Nevertheless, thanks for answer!

This application is not first.

Papierkorb says:

Good to see Qt being used in the automotive environment 🙂 Although the developer was a bit hard to understand. Anyway, the software looks like a good start!

There’s a little typo: “Nürburgring Nordcshleife” => “Nordschleife”

@Papierkorb: Thanks, fixed. My German is good only for ordering beer 😉

huytard says:

agreed, subtitles would have been nice. but still really cool!

Teppo says:

Looks like the best place to look for more resources to make the best use of.

Generally I don’t read article on blogs, however I would like to say that this write-up very pressured me to check out and do so! Your writing style has been surprised me. Thanks, very great article.
